Uso de ibuprofeno en el tratamiento de pacientes pediátricos con poliuria y disnatremia. Reporte de una serie de casos / Ibuprofen use for the treatment of pediatric patients with polyuria and dysnatremia. A case series report

Los niños con lesiones selares y/o supraselares pueden presentar diabetes insípida central con posterior secreción inadecuada de hormona antidiurética. Nosotros observamos, en algunos casos, aumento de la incidencia de poliuria, natriuresis e hiponatremia, tríada diagnóstica del síndrome cerebral perdedor de sal. Aquí comunicamos la evolución de 7 pacientes con antecedentes de daño agudo del sistema nervioso central y diabetes insípida central seguida por síndrome cerebral perdedor de sal. Como tratamiento aportamos secuencialmente fluidos salinos parenterales, cloruro de sodio oral, desmopresina, mineralocorticoides e incluso tiazidas. Ante la persistencia de poliuria con hiponatremia, agregamos ibuprofeno. Como resultado de este esquema terapéutico secuencial, este grupo redujo significativamente los valores de diuresis diaria de 10 ml/kg/h a 2 ml/kg/h en un tiempo promedio de 5 días, normalizando también las natremias (de 161 mEq/L a 143 mEq/L) en un tiempo promedio de 9 días. En ningún caso observamos efectos adversos asociados al tratamiento.

Children with sellar and/or suprasellar lesions may develop central diabetes insipidus with subsequent inappropriate antidiuretic hormone secretion. An increased incidence of polyuria, natriuresis, and hyponatremia has been reported in some cases, which make up the diagnostic triad of cerebral salt wasting syndrome. Here we report the clinical course of 7 patients with a history of acute central nervous system injury and central diabetes insipidus followed by cerebral salt wasting syndrome. Treatment included the sequential use of parenteral saline solution, oral sodium chloride, desmopressin, mineralocorticoids, and even thiazides. Due to persistent polyuria and hyponatremia, ibuprofen was added. As a result of this sequential therapeutic regimen, daily urine output reduced significantly from 10 mL/ kg/h to 2 mL/kg/h over an average period of 5 days, together with a normalization of natremia (from 161 mEq/L to 143 mEq/L) over an average period of 9 days. No treatment-related adverse effects were observed in any case.

Efficacy of Ibuprofen after Total Hip Arthroplasty to Prevent Heterotopic Ossification: Systematic Review and Meta-Analysis / Eficácia do ibuprofeno após artroplastia total de quadril para prevenção de ossificação heterotópica: Revisão sistemática e metanálise

Abstract The objective of this study was to conduct a systematic review and meta-analysis of relevant randomized control trials (RCTs) to determine the role of ibuprofen, as well as the optimum dose and duration of therapy, in preventing the incidence of heterotopic ossification (HO) after primary total hip arthroplasty (THA). A literature search was performed using the PubMed/MEDLINE and Cochrane Library databases for RCTs that compared the use of ibuprofen versus placebo as prophylaxis for HO in patients after THA. The main outcomes for this study were overall occurrence of HO, occurrence according to the Brooker classification, and gastrointestinal complications. A total of 27 potential articles were identified from the database. Eventually, four trials with 1,153 patients were included in the final analysis. When compared with placebo, the use of ibuprofen is associated with a reduction in the incidence of HO at the 3- and 12-month follow-up appointments, as well as the incidence of Brooker II and III HO (p < 0.05). However, there was no significant difference between the ibuprofen and placebo groups in terms of treatment discontinuation due to gastrointestinal complications or the incidence of Brooker I and IV HO (p > 0.05). The existing data indicates that ibuprofen is safe and efficacious in reducing the total incidence of HO along with Brooker II and III HO at follow-up. However, due to the small number of studies, the conclusions are limited; therefore, more high-quality clinical trials are required to develop guidelines for optimal dose and duration of therapy.

Resumo O objetivo deste estudo foi realizar uma revisão sistemática e metanálise de estudos clínicos randomizados (ECRs) relevantes para determinar o papel do ibuprofeno, sua dose ideal, e a duração do tratamento na prevenção de ossificação heterotópica (OH) após a artroplastia total primária do quadril (ATQ). Uma pesquisa bibliográfica foi feita nos bancos de dados PubMed/MEDLINE e Cochrane Library para a obtenção de ECRs quecomparassem ouso de ibuprofeno edeplacebo como profilaxiaparaOHem pacientes submetidos à ATQ. Os principais desfechos deste estudo foram ocorrência geral de OH, classificação de Brooker da OH, e complicações gastrintestinais. No total, 27 artigos foram identificados nos bancos de dados e 4 estudos, com 1.153 pacientes, foram incluídos na análise final. Em comparação ao placebo, o uso de ibuprofeno reduziu a incidência de OH aos 3 e 12 meses de acompanhamento e a incidência de OH Brooker II e III (p < 0,05). No entanto, não houve diferença significativa entre os grupos que receberam ibuprofeno e placebo em termos de interrupção do tratamento devido a complicações gastrintestinais ou da incidência de OH Brooker I e IV (p > 0,05). Os dados existentes indicam que o ibuprofeno é seguro e eficaz na redução da incidência total de OH e de OH Brooker II e III durante o acompanhamento. No entanto, as conclusões são limitadas devido ao pequeno número de estudos; logo, mais estudos clínicos de alta qualidade são necessários para o desenvolvimento de diretrizes em relação à dose e duração ideal da terapia.

Comparación: acetaminofén vs ibuprofeno para el tratamiento de los síntomas en pacientes con infección por SARS-CoV-2 / Comparação: paracetamol vs ibuprofeno para o tratamento de sintomas em pacientes com infecção por SARS-CoV-2 / Comparison: acetaminophen vs ibuprofen for the treatment of symptoms in patients with SARS-CoV-2 infection

La propagación del COVID-19 fue expedita y tras varios informes la eficacia de algunos medicamentos antiinflamatorios no esteroideos, como el ibuprofeno, estuvo bajo sospecha. Mientas que el paracetamol (acetaminofén) se sugirió como una alternativa segura y recomendable para el manejo temprano y domiciliario del dolor y fiebre en pacientes. Objetivo. Comparar el uso del acetaminofén vs ibuprofeno para tratamiento de los síntomas en pacientes con infección por SARS-COV-2". Metodología. La investigación es una revisión sistemática, donde, se analizaron artículos científicos publicados en revistas vinculadas a áreas de salud, disponibles en buscadores y plataformas digitales tales, como Scienedirect, Pubmed, Elsevier y Springer Link. Las búsquedas se realizaron utilizando las palabras claves previamente definidas. Conclusión. El uso del ibuprofeno ha estado en duda desde sus inicios, en pacientes con COVID-19. Sin embargo, ningún estudio afirma asociar el uso del mismo con aumentos importantes en estadía hospitalaria, ingresos en UCI, necesidad de ventilación mecánica, ni mortalidad. Sin embargo, el acetaminofén ha sido utilizado desde un principio, su uso no estuvo en duda, pero los hallazgos recientes parecen indicar que no es tan eficaz como se pensaba en un principio. Siendo bastante inferior en la comparación directa con el ibuprofeno.

The spread of COVID-19 was expeditious and after several reports the efficacy of some non-steroidal anti-inflammatory drugs, such as ibuprofen, was under suspicion. While paracetamol (acetaminophen) was suggested as a safe and recommended alternative for early and home management of pain and fever in patients. Objective. To compare the use of acetaminophen vs ibuprofen for symptom management in patients with SARS-COV-2 infection". Methodology. The research is a systematic review, where scientific articles published in journals related to health areas, available in search engines and digital platforms such as Scienedirect, Pubmed, Elsevier and Springer Link, were analyzed. Searches were performed using previously defined keywords. Conclusion. The use of ibuprofen has been in question since its inception in patients with COVID-19. However, no study claims to associate its use with significant increases in hospital stay, ICU admissions, need for mechanical ventilation, or mortality. However, acetaminophen has been used from the beginning, its use was not in doubt, but recent findings seem to indicate that it is not as effective as originally thought. It is quite inferior in direct comparison with ibuprofen.

Conducto arterioso permeable: mecanismos moleculares del cierre y su relacion con el tratamiento

El conducto arterioso establece una conexión esencial entre la arteria aorta descendente proximal y la arteria pulmonar principal cerca del origen de la rama pulmonar izquierda, siendo vital durante la vida fetal y generalmente cerrándose poco después del nacimiento en la mayoría de los recién nacidos a término; no obstante, en recien nacidos pretermino, es común la persistencia del conducto arterioso debido a estímulos vasodilatadores que mantienen su permeabilidad y flujo sanguíneo constante, requiriendo enfoques de tratamiento que involucran la inhibición de la prostaglandina E2 y antiinflamatorios no esteroides, aunque la comparación de su eficacia con métodos conservadores sigue siendo poco clara, especialmente en recién nacidos prematuros extremos. La presente revisión tiene como objetivo proporcionar una comprensión de los mecanismos moleculares clave detrás de la fisiopatología del conducto arterioso persistente y su abordaje terapéutico.

The ductus arteriosus establishes an essential connection between the proximal descending aorta and the main pulmonary artery near the origin of he left pulmonary branch, being vital during fetal life and generally closing shortly after birth in most term newborns; However, in preterm infants, persistence of the ductus arteriosus is common due to vasodilator stimuli that maintain its patency and constant blood flow, requiring treatment approaches involving prostaglandin E2 inhibition and nonsteroidal anti-inflammatory drugs, although the comparison of their efficacy with conservative methods remains unclear, especially in extremely preterm infants. The present review aims to provide an understanding of the key molecular mechanisms behind the pathophysiology of patent ductus arteriosus and its therapeutic approach.

Interchangeability of medications and biopharmaceutical implication of taking drugs with fluids other than water: ibuprofen case study

Abstract The aim of this study was to compare the dissolution properties of ibuprofen solid oral dosage forms commercially available in Bosnia and Herzegovina and to estimate the influence of dissolution medium composition on the drug release. Eight products (A-H) were subjected to in vitro dissolution test using experimental conditions described in USP42-NF37. Dissolution properties of one selected product were examined in the presence of alcohol (22.2% v/v) and fruit juice (22.2% v/v). Products marked B-H complied with the pharmacopeial criteria. Dissolution profile of product B was similar with dissolution profiles of products D, E, F and G and similarity was also found between products A-D, C-G, D-G and E-F. Drug release from most of the examined preparations fitted best to the Weibull kinetic model. In the presence of alcohol in the medium, higher amount of ibuprofen was dissolved. Contrary, ibuprofen dissolved in the presence of fruit juice was significantly lower. Differences in the dissolution profiles of investigated preparations suggest that their interchangeability should be additionally considered and demonstrated with in vivo bioequivalence studies. Presence of different substances in the medium can affect dissolution properties of ibuprofen, emphasizing the importance of the patient's compliance.

The effects of metformin, acetylsalicylic acid and ibuprofen on telomerase enzyme activity: inhibitory effect of ibuprofen

Abstract Telomerase enzyme is necessary for the elongation of telomeres while telomerase being critical for aging and cancer. Metformin, ibuprofen, and acetylsalicylic acid used in this research are drugs that millions of people already use and that many are likely to use in future. In this study, the effects of these drugs on telomerase activity of Mus musculus swiss albino mice in liver tissue were investigated and the telomerase activity was measured with a PCR-ELISA based kit. In the study a possible connection between telomerase enzyme activity and activities of antioxidant enzymes was also investigated by determining the activity of superoxide dismutase (SOD) and catalase enzymes. The data obtained show that metformin slightly decreased telomerase enzyme activity in low dose application; however, this change was not statistically significant. In ibuprofen application, there was a significant inhibitory effect when high doses were used; whereas, there was a slight inhibitory effect at low doses. In acetylsalicylic acid application, a slight activator effect was detected; it was not statistically significant, though. Metformin was observed to increase catalase and SOD activities in general while low and high doses of acetyl salicylic acid showed different effects. In addition, ibuprofen caused a statistically significant increase in liver SOD values. It is important to note that this study demonstrated a significant inhibitory effect of ibuprofen on telomerase enzyme activity in animal models..

Effect of ibuprofen and low-intensity pulsed ultrasound on the reduction of pain after initial archwire placement: a double-blind randomized clinical trial / Efecto del ibuprofeno y el ultrasonido pulsado de baja intensidad en la reducción del dolor después de la colocación inicial del arco de ortodoncia: un ensayo clínico aleatorizado doble ciego

Objective: This study aimed to compare the effect of ibuprofen and low intensity pulsed ultrasound (LIPUS) on the reduction of pain after the placement of initial archwire in orthodontic patients. Material and Methods: This double-blind clinical trial study was carried out on 60 female candidates for fixed orthodontic treatment referring to the Orthodontic Department of School of Dentistry in Mashhad University of Medical Sciences, Mashhad, Iran, during 2015-2016. The subjects were divided into four groups of ibuprofen, LIPUS, placebo, and mock LIPUS. A questionnaire and a rectangular and flexible cubic silicone were given to each patient to record the severity of pain based on the visual analog scale at specified time points (i.e., 2 h, 6 h, at bedtime, 2nd, 3rd, and 7th days after archwire placement) when biting the silicone block with the anterior and posterior teeth and without biting at all. Repeated measures analysis of variance was used in order to compare the pain severity at different time points. Results: The comparison of pain severity at various time points showed that the highest and lowest mean scores of pain were reported at bedtime and seven days after the intervention (p<0.001). In each of the three conditions (i.e., biting the silicone block with the anterior and posterior teeth and without biting the teeth) at six time points (i.e., 2 h, 6 h, at bedtime, 2nd, 3rd, and 7th days following archwire placement), no significant difference was observed in the severity of pain (p>0.05). Conclusion: In conclusion, LIPUS (with a frequency of 1 MHz and an intensity of 100 mW) and ibuprofen have no significant effects on reduction of the pain severity at different time points and various conditions in orthodontic patients.

Objetivo: Este estudio tuvo como objetivo comparar el efecto del ibuprofeno y el ultrasonido pulsado de baja intensidad (LIPUS) en la reducción del dolor después de la colocación del arco inicial en pacientes de ortodoncia. Material y Métodos: Este estudio de ensayo clínico doble ciego se llevó a cabo en 60 candidatas a tratamiento de ortodoncia fija referidas al Departamento de Ortodoncia de la Facultad de Odontología de la Universidad de Ciencias Médicas de Mashhad, Mashhad, Irán, durante 2015-2016. Los sujetos se dividieron en cuatro grupos: ibuprofeno, LIPUS, placebo y LIPUS simulado. Se entregó un cuestionario y un bloque de silicona cúbica rectangular y flexible a cada paciente para registrar la intensidad del dolor según la escala analógica visual en puntos de tiempo específicos (es decir, 2 h, 6 h, hora de acostarse, 2do, 3er y 7mo día después de la colocación del arco) al morder el bloque de silicona con los dientes anteriores y posteriores, y sin morder en absoluto. Se utilizó el análisis de varianza de medidas repetidas para comparar la intensidad del dolor en diferentes momentos.Resultados: La comparación de la intensidad del dolor en varios puntos de tiempo mostró que las puntuaciones medias de dolor más altas y más bajas se informaron a la hora de acostarse y siete días después de la intervención (p<0,001). En cada una de las tres condiciones (es decir, al morder el bloque de silicona con los dientes anteriores y posteriores, y sin morder) en seis momentos (2 h, 6 h, antes de acostarse 2do, 3er y 7mo día después de la colocación del arco), no se observó diferencia significativa en la severidad del dolor (p>0.05).Conclusión: En conclusión, LIPUS (con una frecuencia de 1 MHz y una intensidad de 100 mW) y el ibuprofeno no tienen efectos significativos en la reducción de la severidad del dolor en diferentes puntos de tiempo y diversas condiciones en pacientes de ortodoncia.

A Randomized Double-Blind Comparative Study of Efficacy and Safety Between Low-Dose Etoricoxib and Ibuprofen Coadministered with Low-Dose Paracetamol for Dental Pain

Objective: To study the safety and efficacy of low-dose etoricoxib and low-dose paracetamol versus ibuprofen and low-dose paracetamol treatments in patients who experienced acute pain after tooth extraction. Methods: A total of 80 patients were recruited and randomized to two study groups, i.e., EP and IP. Group EP received etoricoxib 30 mg once a day and add-on paracetamol 325 mg eight-hourly, and Group IP received ibuprofen 400 mg and paracetamol 325 mg eight-hourly for three days. The analgesic efficacy was assessed by a visual analog scale, pain relief score, and global evaluation score. Patients were assessed at 0, 6, 24, 48, and 72 h. Safety was assessed by the patient’s estimation of the severity of adverse drug reactions using a 3-point scale and the type of adverse drug reactions reported by the patients after 72 h. Results: Mean pain intensity reduction, mean pain relief score, and global evaluation score all showed better analgesic efficacy results in Group EP as compared to Group IP but were not significant (P > 0.05) at 6, 24, 48, and 72 h, respectively. No patient had reported any serious adverse drug reaction in both the groups. Mild to moderate adverse reactions were reported in 20% cases in the IP group and 10% cases in the EP group; however, the incidence of GIT intolerance was seen in 17.5% of the cases in the IP group and none in the EP group. Conclusion: Low-dose etoricoxib with low-dose paracetamol has comparable analgesic efficacy with better safety than therapeutic dose ibuprofen and low-dose paracetamol.

Qual Deve Ser o Tratamento de Primeira Linha para o Fechamento de Persistência de Canal Arterial Hemodinamicamente Significativo em Bebês Prematuros? / What Should be the First-line Treatment for the Closure of Hemodynamically Significant Patent Ductus Arteriosus in Premature Infants?

Resumo Fundamento É importante saber qual medicamento usar como tratamento de primeira linha para fechar o duto. Objetivos O objetivo deste estudo é comparar a eficácia e os efeitos colaterais das formas intravenosas (IV) de ibuprofeno e paracetamol e contribuir para a literatura investigando o primeiro medicamento selecionado no tratamento clínico da persistência do canal arterial (PCA). Métodos Nosso estudo foi realizado entre janeiro de 2017 e dezembro de 2019. Foram incluídos no estudo bebês prematuros com peso ao nascer (PN) ≤1500 g e idade gestacional (IG) ≤32 semanas. No período do estudo, todos os bebês com persistência do canal arterial hemodinamicamente significativa (hsPCA) receberam ibuprofeno intravenoso (IV) como resgate como tratamento clínico primário ou tratamento com paracetamol IV se houvesse contraindicações para o ibuprofeno. Os pacientes foram divididos em dois grupos: pacientes que receberam ibuprofeno IV e pacientes que receberam paracetamol IV. Resultados Desses pacientes, 101 receberam paracetamol IV e 169 receberam ibuprofeno IV. A taxa de sucesso do fechamento da PCA com o primeiro curso do tratamento foi de 74,3% no grupo de paracetamol IV e 72,8% no grupo de ibuprofeno IV (p=0,212). Conclusões Nossos resultados mostram que o paracetamol IV é tão eficaz quanto o ibuprofeno IV no tratamento de primeira linha de hsPCA, podendo se tornar o tratamento preferencial para o controle de hsPCA.

Abstract Background It is important which medicine to use as a first-line treatment to close the duct. Objectives The aim of this study is to compare the effectiveness and side effects of intravenous (IV) forms of ibuprofen and paracetamol and to contribute to the literature investigating the first drug selected in the medical treatment of patent ductus arteriosus (PDA). Methods Our study was conducted between January 2017 and December 2019. Premature infants with birth weight (BW) ≤1500 g and gestational age (GA) ≤32 weeks were included in the study. In the study period, all infants with hemodynamically significant patent ductus arteriosus (hsPDA) were given rescue intravenous (IV) ibuprofen as a primary medical treatment or IV paracetamol treatment if there were contraindications for ibuprofen. The patients were divided into two groups: patients receiving IV ibuprofen and patients receiving IV paracetamol. Results Of these patients, 101 were given IV paracetamol and 169 were given IV ibuprofen. The success rate of PDA closure with first-course treatment was 74.3% in the IV paracetamol group and 72.8% in the IV ibuprofen group (p=0.212). Conclusions Our results show that IV paracetamol is as effective as IV ibuprofen in the first-line treatment of hsPDA, and can become the preferred treatment for the management of hsPDA.

Efficacy and safety of initial treatment with ibuprofen or paracetamol and rescue treatment with high-dose ibuprofen in preterm infants with patent ductus arteriosus / 中华全科医师杂志

Objective:To investigate the efficacy and safety of initial treatment with ibuprofen or paracetamol and rescue treatment with high-dose ibuprofen in preterm infants with haemodynamically significant patent ductus arteriosus (hsPDA).Methods:The preterm infants (gestational age ≤ 32 weeks) with hsPDA who were admitted to neonatal intensive care unit (NICU) of Xuzhou Central Hospital from October 2016 to November 2019 were enrolled in the study. A total of 110 eligible cases were included and randomly divided into three groups for initial treatment: 38 cases received oral ibuprofen 10 mg/kg, and 5 mg/kg after 24 h and 48 h (ibuprofen group), 37 cases received oral paracetamol 15 mg/kg, q.8.h for 3 d (paracetamol group) and 35 cases received oral injection water 1 ml/kg, and 0.5 ml/kg after 24 h and 48 h (conservative management group). The preterm infants who failed in the initial treatment were given high-dose ibuprofen for rescue treatment (oral ibuprofen 20mg/kg, and 10 mg/kg after 24 h and 48 h). Serum creatinine, cystatin C, glutamic-pyruvic transaminase (GPT), total bilirubin, fecal occult blood and urinary prostaglandin E 2 were measured; echocardiography and brain color Doppler ultrasonography examinations were performed before and after treatment. Urine output and complications were recorded. The data were analyzed by ANOVA, t-test, non-parametric test, chi-square test and Pearson correlation coefficient with SPSS 20.0 statistical software. Results:During initial treatment, the success rates of ibuprofen group and paracetamol group were higher than that of conservative management group [71.1% (27/38) and 70.3%(26/37) vs. 40.0% (14/35), P=0.008 and 0.010]. Thirty one patients, who failed in initial treatment, received rescue treatment (8, 7, 16 cases from ibuprofen, paracetamol and conservative groups, respectively). The success rate of rescue treatment with high-dose ibuprofen was 58.1% (18/31). During initial treatment, there were no significant differences in the incidence of oliguria, upper gastrointestinal bleeding, positive fecal occult blood tests, Ⅲ-Ⅳ grade intraventricular hemorrhage, and ≥Ⅱ stage necrotizing enterocolitis among the three groups (all P>0.05). There were no significant differences in the incidence of above complications between rescue treatment and initial treatment [6.5% (2/31) vs. 6.4%(7/110), 3.2%(1/31) vs. 4.5%(5/110), 12.9%(4/31) vs. 6.4%(7/110), 0 vs. 4.5%(5/110), 3.2%(1/31) vs. 1.8%(2/110), all P>0.05]. The changes of serum creatinine and GPT before and after treatment were not significant in all groups ( P>0.05). Serum cystatin C were increased in both ibuprofen group[(0.44±0.17)μmol/L] and paracetamol group [(0.18±0.09)μmol/L] after treatment ( t=-15.70, -14.64; P<0.001), and the increase in ibuprofen group was greater than that in paracetamol group ( P<0.001). Urinary prostaglandin E 2 were decreased in both ibuprofen group [(-11.63±3.70)ng/L] and paracetamol group[(-4.89±1.91)ng/L] after treatment ( t=15.57, 7.03; P<0.001), and the decrease in ibuprofen group was greater than that in paracetamol group ( P<0.001). Serum cystatin C was not significantly increased after high dose ibuprofen rescue treatment [(1.67±0.17)mg/L vs.(1.71±0.21)mg/L; t=-1.12, P=0.273]. Conclusion:Both initial treatment with ibuprofen or paracetamol and rescue treatment with high-dose ibuprofen can effectively promote hsPDA closure in preterm infants without increase of complications. However, renal function indexes such as urine output and serum cystatin C should be monitored. The high-dose ibuprofen is relatively safe, and can be used as one of rescue treatment.

Prevalence, impact, and management perception of dysmenorrhea among university students: A cross-sectional study

Abstract Dysmenorrhea is a common condition among females that is characterized by painful cramps before or during menstruation. It is considered as a common gynecological complaint that affects the quality of women's life. The study evaluated prevalence of dysmenorrhea, its impact, associated risk factors, and the management strategies adopted by female university students in Taif city, Saudi Arabia. A cross-sectional study was conducted among 562 female students aged 18-30 years at the university level. The results showed a high prevalence rate of dysmenorrhea (79.4%) among the students. The most common risk factors were family history (87.4%) and length of menstruation (79%). Half (50.2%) of the respondents were absent at the university at least 1 day every month. The most widely used medications by the respondents were ibuprofen (42%) and paracetamol (40%), whereas only 3% used mefenamic acid, despite that they experienced complete pain relief with mefenamic acid. High prevalence rate of dysmenorrhea associated with risk factors such as family history and length of menstruation, was found among university students. However, pain and associated symptoms affect the quality of life.

Effects of polyvinylpyrrolidone and poly (ethylene glycol) on preparation of ibuprofen pharmaceutical cocrystal

Abstract In this study, we investigated the effects of polymers on the pharmaceutical cocrystal formation process. Ibuprofen (IBU) was selected as the active pharmaceutical ingredient (API), nicotinamide (NIC) and saccharin (SAC) as the cocrystal coformer (CCF), ethanol/water as the solvent, polyvinylpyrrolidone (PVP) and poly (ethylene glycol) (PEG) as the representative polymers. We prepared IBU-NIC and IBU-SAC cocrystals in ethanol-water cosolvent in the absence or presence of polymers. Cocrystal screening products were characterized by FTIR, DSC, PXRD, and HPLC. The results showed that the mixture of IBU and IBU-NIC cocrystal can be prepared in ethanol-water cosolvent without polymers. The addition of PVP facilitates the formation of pure IBU-NIC cocrystal; however, no cocrystal was formed in PEG solutions. SAC could not cocrystallize with IBU in the ethanol-water solvent in the absence of polymers. Neither PVP nor PEG could facilitate the formation of the IBU-SAC cocrystal.

Evaluation of copaiba oil as enhancer of ibuprofen skin permeation

Abstract The administration of medications on the skin through transcutaneous routes is a practice that has been used by mankind for millennia. Some studies have been reporting the use of terpenes and natural oils rich in terpenes as an enhancer of cutaneous penetration. Copaiba oil, due to its rich content of terpenes, presents itself as a great choice of penetration enhancer for drugs administered on the skin. In this study, we developed two cream formulations containing 5% of ibuprofen (IBU) and copaiba oil: IBCO5 and IBCO10 with 5% and 10% of copaiba oil respectively. Ex vivo cutaneous penetration/permeation studies of IBU were performed using pig ear skin as biological membrane in the Franz-type diffusion cells. The steady-state flux of IBU samples, IBCO5 (35.72 ± 6.35) and IBCO10 (29.78 ± 2.41) were significantly higher when compared with control without copaiba oil (10.32 ±1.52) and with a commercial product (14.44 ± 2.39). In the penetration analysis, the amount of IBU found in the samples IBCO5 and IBCO10 was markedly higher in the dermis than epidermis. Our results showed that copaiba oil possesses attracting properties in promoting skin penetration and permeation of IBU when added into cream formulations.

Patent ductus arteriosus closure: experience from a tertiary referral center / Experiência de uma maternidade terciária no fechamento do canal arterial patente

ABSTRACT Objective: To characterize the number and methods of closure of Persistent Ductus Arteriosus (PDA) over a span of 16 years in a third level maternity hospital. Methods: Retrospective study of neonates born between January 2003 and Deccember 2018, who underwent ductus arteriosus closure by pharmacological, surgical and/or transcatheter methods. Gestational age, birth weight, number and methods of closures per year were evaluated. The success rate of the pharmacologic method was calculated, as well as the mortality rate. The association between mortality and birthweight, treatment used and treatment failure was explored. Results: There were 47,198 births, 5,156 were preterm, 325 presented PDA and 106 were eligible for closure (median gestational age - 27 weeks, birthweight <1000 g - 61%). Frequency of PDA closure decreased during the study period, especially starting in 2010. Success rate with pharmacologic treatment was 62% after the first cycle and 74% after the second. After drug failure, 12 underwent surgical ligation and two underwent transcatheter closure. Exclusive surgical ligation was indicated in four infants. Ibuprofen replaced indomethacin in 2010, and acetaminophen was used in three infants. Among the 106 infants, hospital mortality was 12% and it was associated with birthweight <1000 g (13/65 <1000 vs. 0/41 >1000 g; p=0.002) and with failure in the first pharmacologic treatment cycle (13/27 with failure, vs. 0/75 without failure; p<0.001). Conclusions: The national consensus published in 2010 for the diagnosis and treatment of PDA in preterm infants led to a decrease in the indication for closure. Pharmacological closure was the method of choice, followed by surgical ligation. Birthweight <1000 g and first cycle of pharmacologic treatment failure were associated with higher mortality.

RESUMO Objetivo: Caraterizar o número e métodos de fechamento de canal arterial durante 16 anos numa maternidade de nível terciário. Métodos: Estudo retrospetivo de nascidos entre 01 de janeiro de 2003 a 31 de dezembro de 2018 submetidos a fechamento do canal arterial por métodos farmacológico, cirúrgico e/ou percutâneo. Avaliaram-se idade gestacional, sexo, peso ao nascimento, número de fechamentos por ano e método utilizado. Aferiram-se as taxas de sucesso de método farmacológico e de mortalidade e sua associação com peso ao nascer, fármaco utilizado e insucesso do fechamento. Resultados: Verificaram-se 47.198 recém-nascidos, 5.156 prematuros, dos quais 325 com canal arterial patente, sendo 106 com indicação para fechamento (idade gestacional mediana 27 semanas, peso <1000 g em 61%). Verificou-se diminuição do número de fechamentos ao longo dos anos, sobretudo a partir de 2010. O fechamento ocorreu em 62% após primeiro ciclo de tratamento farmacológico e em 74% após segundo. Após insucesso farmacológico, 12 realizaram ligadura cirúrgica e dois, fechamento percutâneo. Houve indicação de ligadura cirúrgica exclusiva em quatro. O ibuprofeno substituiu a indometacina em 2010. O acetaminofen foi usado em três doentes. A mortalidade nos 106 pacientes foi de 12%, associando-se ao peso ao nascer (13/65 <1000 vs. 0/41 >1000 g; p=0,002) e à falha do primeiro ciclo de tratamento farmacológico (13/27 com falha vs. 0/75 com sucesso; p<0,001). Conclusões: Consenso nacional de 2010 para diagnóstico e tratamento do canal arterial nos prematuros levou à diminuição do número de fechamentos desse canal. O fechamento farmacológico foi o método mais utilizado, seguido da ligadura cirúrgica. Peso <1000 g e falha no primeiro ciclo de fechamento farmacológico se associaram à maior mortalidade.

Preemptive use of intravenous ibuprofen to reduce postoperative pain after lower third molar surgery: a systematic review of randomized controlled trials

This study aimed to systematically review the literature to assess the effect of preemptive intravenous ibuprofen on pain reduction after lower third molar surgery. Nine databases (PubMed, Scopus, LILACS, SciELO, Embase, Web of Science, Cochrane, Open Gray, and Open Thesis) were used as sources of research, including "grey literature." The protocol was registered in PROSPERO. Only randomized clinical trials evaluating the effects of preemptive intravenous ibuprofen on pain during and immediately after the extraction of lower third molars were included, without restrictions of year and language. Two reviewers independently performed the study selection, data extraction, and assessment of the risk of bias. The "Joanna Briggs Institute for Randomized Controlled Trials" tool was used to assess the risk of bias. Each study was categorized according to the percentage of positive responses to the questions corresponding to the assessment instrument. The results were measured narratively/descriptively. The initial search resulted in 3,257 records, of which only three studies (n=150 participants) met the eligibility criteria and were included in the qualitative analysis. All studies were published in 2019. The risk of bias ranged from low to moderate. Two studies found significant pain reduction within 48 h after the procedure. In conclusion, the use of preemptive intravenous ibuprofen for extracting third molars reduces pain and analgesic consumption after the surgical procedure.

Effectiveness of Manual Physical Therapy and NSAIDs as a Combination Therapy in Arthritis Patient-A Case Series

Among various types of arthritis Osteoarthritis (OA), Psoriatic arthritis (PA) and Gouty arthritis (GA) are the major ones which have been studied and cause hindrance in movements in many patients. Here we have discussed the treatment modality, a combination of manual therapy and NSAIDs (Ibuprofen) for relieving the symptoms of arthritis. A total of six patients were included consisting of osteoarthritis, psoriatic arthritis and gouty arthritis who presented at the medical office of Dr. Barengolts (MD in USA) and Aybek Izzatov (MD in Uzbekistan) Tyan Anmo Massage School. The study was conducted from October 2019 to March 2020. The treatment consisted of 30 sessions performed for half a year, one week per month (5 days in a month). Significant improvement in symptoms was seen as after 6 months we saw there was reduction in morning stiffness and improved range of motion. The pain score shifted from 5-6 to 2-3 on VAS pain scale. The results signify that the combination therapy wherein manual therapy and NSAIDs worked in an effective way to reduce the level of severity of pain and other associated symptoms.

Study of the antifungal activity of ibuprofen and its association with amphotericin B or ketoconazole against Candida spp / Estudio de la actividad antifúngica del ibuprofeno y su asociación con anfotericina B o ketoconazol contra Candida spp / Estudo da atividade antifúngica do ibuprofeno e sua associação com anfotericina B ou cetoconazol contra Candida spp

SUMMARY The objective was evaluating the antifungal activity of ibuprofen alone and when associated with amphotericin B or ketoconazole against Candida species. Strains of C. albicans, C. tropicalis, C. guilliermondii, C. krusei and C. parapsilosis were used. The minimum inhibitory concentration (MIC) was determined by the microdilution method and the association study performed through the checkerboard assay. The concentration of 512 μg/mL inhibited approximately 65% of the tested strains, while against 35% of the strains presented MIC values above 2048 μg/mL. Associations of ibuprofen with amphotericin B against C. tropicalis and ibuprofen with ketoconazole against C. krusei showed synergistic effect. Antagonistic effects were evidenced in the combination of ibuprofen with amphotericin B against C. guilliermondii and C. albicans, as well as in the association of ibuprofen with ketoconazole against C. albicans and C. tropicalis. Through the experiments, it was found that ibuprofen showed antifungal activity against most of the Candida species tested. The combinations of ibuprofen and antifungals had synergistic effects. However, antagonistic results were evidenced in the association with ibuprofen, which would make clinical applicability difficult. Therefore, studies of this combined activity should be investigated, considering that this association may be positive for anti-fungal therapy.

RESUMEN El objetivo fue evaluar la actividad antifúngica del ibuprofeno solo y asociado con anfotericina B o ketoconazol contra especies de Candida. Se utilizaron cepas de C. albicans, C. tropicalis, C. guilliermondii, C. krusei y C. parapsilosis. La concentración inhibitoria mínima (MIC) se determinó mediante el método de microdilución y el estudio de asociación fue realizado a través del ensayo de checkboard. La concentración de 512 μg/mL inhibió aproximadamente el 65% de las cepas analizadas, mientras 35% de las cepas presentaron valores de MIC superiores a 2048 μg/mL. Las asociaciones de ibuprofeno con anfotericina B contra C. tropicalis e ibuprofeno con ketoconazol contra C. krusei mostraron un efecto sinérgico. Se evidenciaron efectos antagonistas en la combinación de ibuprofeno con anfotericina B contra C. guilliermondii y C. albicans, así como en la asociación de ibuprofeno con ketoconazol contra C. albicans y C. tropicalis. Se descubrió, a través de los experimentos, que el ibuprofeno mostró actividad antifúngica contra la mayoría de las especies de Candida probadas. Las combinaciones de ibuprofeno y antifúngicos tuvieron efectos sinérgicos. Sin embargo, se evidenciaron resultados antagónicos en la asociación con ibuprofeno, lo que dificultaría la aplicabilidad clínica. Por lo tanto, los estudios de esta actividad combinada deben investigarse, considerando que esta asociación puede ser positiva para la terapia antimicótica.

RESUMO O objetivo do estudo foi avaliar a atividade antifúngica do ibuprofeno sozinho e quando associado com anfotericina B ou cetoconazol contra espécies de Candida. Foram utilizadas cepas fúngicas de C. albicans, C. tropicalis, C. guilliermondii, C. krusei e C. parapsilosis, entre isolados clínicos e cepas padrão. A concentração inibitória mínima (CIM) foi determinada pela técnica de microdiluição e o estudo de associação realizado através do ensaio checkerboard. A concentração de 512 μg/mL foi capaz de inibir, aproximadamente, 65% das cepas ensaiadas, enquanto que 35% das estirpes apresentaram valores da CIM acima de 2048 μg/mL. Associações do ibuprofeno com anfotericina B contra C. tropicalis e ibuprofeno mais cetoconazol contra C. krusei mostraram efeito sinérgico. Efeitos antagônicos foram evidenciados na combinação do ibuprofeno com anfotericina B contra C. guilliermondii e C. albicans, como também na associação do ibuprofeno com cetoconazol contra C. albicans e C. tropicalis. Por meio dos experimentos, pôde-se afirmar que o ibuprofeno exerceu atividade antifúngica contra a maioria das espécies de Candida ensaiadas. Os efeitos das combinações entre o ibuprofeno e os antifúngicos promoveram efeitos sinérgicos. No entanto, resultados antagônicos foram evidenciados na associação com o ibuprofeno, o que dificultaria aplicabilidade clínica. Logo, estudos dessa atividade combinada devem ser investigados, pois esta associação pode traçar pontos positivos na terapia antifúngica.

Evaluation of ibuprofen prescriptions into a Psychiatric Hospital: regarding safety, indication, and dose / Avaliação das prescrições de ibuprofeno em um hospital psiquiátrico: aspectos de segurança, indicação e dose

Introduction: non-steroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen are widely used throughout the world. In the psychiatric hospital, where this study was conducted, drugs such as selective serotonin reuptake inhibitors (SSRI) and lithium are widely used and may interact with ibuprofen (IBU). The literature also shows that ibuprofen may lead to changes in the central nervous system, which may trigger the imbalance of psychiatric disorders. Objective: to evaluate whether both the frequency of use and the prescriptions of ibuprofen are in agreement with the information contained in the literature regarding safety, indication, and dose. Methodology: retrospective observational cross-sectional study to evaluate the use of ibuprofen on patients from a psychiatric hospital. The prescriptions were evaluated for a 10-month period. Results: of the total number of prescriptions, 43 contained ibuprofen 600 mg. Note that in most cases, the drug was being prescribed according to the literature. However, in some cases there were divergences in the literature regarding: i) safety ­ information about the absence or presence of ulcers (1; 2.3%), gastrointestinal events (0; 0%) and absence of dyspepsia, abdominal pain and discomfort gastrointestinal (11; 25.5%) ­ ii) and the dose, in which in 19 cases (44%) it was higher than recommended by the literature. In addition, in 2 prescriptions (4.7%), the concomitant use of IBU and SSRI was observed and in 5 (11.6%) of IBU and lithium. Conclusion: the use of this drug often escaped safety and dosage criteria concerning scientific literature.

Introdução: os anti-inflamatórios não esteróides (AINEs), como o ibuprofeno, são amplamente utilizados no mundo todo. No hospital psiquiátrico em que este estudo foi realizado, medicamentos como inibidores seletivos da recaptação de serotonina e lítio são amplamente utilizados e sabe-se que podem interagir com o ibuprofeno. A literatura também mostra que o ibuprofeno pode levar a alterações no sistema nervoso central, o que pode desencadear o desequilíbrio dos distúrbios psiquiátricos. Objetivo: avaliar a frequência da utilização do ibuprofeno e se suas prescrições estão de acordo com as informações contidas na literatura com relação à segurança, indicação e dose. Metodologia: realizou-se um estudo transversal observacional retrospectivo para avaliar o uso de ibuprofeno em pacientes de um hospital psiquiátrico. As prescrições foram avaliadas por um período de 10 meses. Resultados: entre as 43 prescrições avaliadas, recomendou-se a dose de 600 mg. Foi observado que, na maioria dos casos, o medicamento estava sendo usado conforme prescrito na literatura. No entanto, em alguns casos houve divergências da literatura em relação a i) segurança ­ informações sobre a ausência ou presença de úlceras (1; 2,3%), de eventos gastrointestinais (0; 0%) e ausência de dispepsia, dor abdominal e desconforto gastrointestinal (11; 25,5%) ­ ii) dose, em que em 19 casos (44%) foi maior do que o preconizado pela literatura. Além disso, em duas (4,7%) prescrições, foi observado o uso concomitante de IBU e ISRS) e em cinco (11,6%) de IBU e lítio. Conclusão: o uso desse medicamento frequentemente de modo geral não obedeceu aos critérios de segurança e dosagem referentes à literatura científica.

Effect of Oral Administration of Ibuprofen on Prothrombin Time, Activated Partial Thromboplastin and Platelet Count in Wistar Albino Rats

Aim:Ibuprofen is analgesic, antipyretic and anti-inflammatory drug, which is widely used as a cheap over-the counter drug(OTC); however, this drug accompanies anti coagulation/anti platelets effects which sometimes might illicit adverse effects. In this study, we investigated effect of ibuprofen on prothrombin time (PT), activated partial thromboplastin time (aPTT) and platelet count using wistar albino rats.Methods:A total of 21 rats grouped into 3(control, acute and chronic exposure groups, with all consisting of 7rats each) was used. The acute and chronic exposure group were given 0.7mg of ibuprofen orally for 1 and 21 days, respectively. Blood sample was collected via cardiac puncture thenanalyzed.Results:PT was significantly higher in both group 2 and 3 (acute and chronic exposure, respectively)than that of the control. Acute exposure group showed the highest PT rise.A PTT was not significantly different between group 2 and 3 versus the control group. Platelet count was significantly lower in both group 2 and 3than that in the control group (p<0.05). Group 3 (chronic exposure) showed the lowest platelet count.Conclusion:Oral administration of ibuprofen affected coagulation parameters and a longer exposure reduce platelets count. A strictly prescription for this drug may be needed to prevent its indiscriminate use
