Stability indicating Rp-UPLC method development and validation for the simultaneous estimation of fosnetupitant and palonosetron in bulk and injection dosage form

Abstract A stability indicating UPLC method has been developed and validated for the simultaneous determination of fosnetupitant and palonosetron in bulk and in injection dosage form. This combination is used for the prevention of acute and delayed nausea and vomiting associated with initial and repeated courses of highly emetogenic chemotherapy for cancer. The chromatographic analysis was performed on an HSS, RP C18 column (2.1 x 100 mm, 1.8 µm) with an isocratic mobile phase composed of 0.25 M potassium dihydrogen orthophosphate buffer (pH 6.5), pH adjusted with dilute sodium hydroxide:acetonitrile (55:45 v/v), at a flow rate of 0.5 mL/min, and the eluents were monitored at an isosbestic point of 286 nm. The developed method was validated according to the ICH guidelines pertaining to specificity, precision, accuracy, linearity and robustness, and the stability indicating nature of the method was established by forced degradation studies. The retention times of fosnetupitant and palonosetron were observed at 1.390 and 2.404 min, respectively. The developed method proved to be accurate and precise. Linearity was established between 4.70 and 14.10 µg/mL for fosnetupitant and between 0.05 and 0.15 µg/mL for palonosetron. The LOD and LOQ were 0.115 and 0.385 µg/mL, respectively, for fosnetupitant, and 0.005 and 0.016 µg/mL, respectively, for palonosetron. Therefore, the proposed UPLC method was reliable, reproducible, precise and sensitive for the quantification of fosnetupitant and palonosetron.

Analytical lifecycle management oriented development and validation of a new stability-indicating ultra-fast liquid chromatographic method: case study of Glycopyrrolate

A new stability-indicating liquid chromatographic method was developed and validated for the estimation of glycopyrrolate in pharmaceutical formulations. A contemporary approach to analytical life-cycle management was followed to develop a robust and reliable chromatographic method. Scouted method variables such as % methanol, the strength of tetra butyl ammonium hydrogen sulfate and mobile phase flow rate were optimized using the design of experiment approach and their effect on critical quality attributes was studied. The critical quality attributes viz. retention time, theoretical plate count and symmetry factor were highly influenced by the three critical method variables. Optimum chromatography was attained on a C-18 column with a mobile phase methanol: 10 mM tetra butyl ammonium hydrogen sulfate (80:20, v/v) flowing at 1.0 mL.min-1. Chromatographic method specificity was ensured by degrading the drug forcefully. Validation studies postulated method acceptability and suitability for estimating glycopyrrolate in both bulk as well as injection formulation. Results for parameters viz. linearity (5-250 µg.mL-1), accuracy (>99%) and precision (<2%) advocated method reliability. Overall the method was reliable and of optimum quality and, possess the potential of application in routine and bio-analytical purposes

Lidocaine alleviates propofol related pain much better than metoprolol and nitroglycerin / Lidocaína é mais eficaz do que metoprolol e nitroglicerina para o alívio da dor relacionada à injeção de propofol

ABSTRACTBACKGROUND AND OBJECTIVES: Injection pain after propofol administration is common and maydisturb patients' comfort. The aim of this study was to compare effectiveness of intravenous(iv) nitroglycerin, lidocaine and metoprolol applied through the veins on the dorsum of hand orantecubital vein on eliminating propofol injection pain.METHOD: There were 147 patients and they were grouped according to the analgesic adminis-tered. Metoprolol (n = 31, Group M), lidocaine (n = 32, Group L) and nitroglycerin (n = 29, GroupN) were applied through iv catheter at dorsum hand vein or antecubital vein. Pain was evalu-ated by 4 point scale (0 - no pain, 1 --- light pain, 2 --- mild pain, 3 --- severe pain) in 5, 10, 15and 20th seconds. ASA, BMI, patient demographics, education level and the effect of pathwaysfor injection and location of operations were analyzed for their effect on total pain score.RESULTS: There were no differences between the groups in terms of total pain score (p = 0.981).There were no differences in terms of total pain score depending on ASA, education level,location of operation. However, lidocaine was more effective when compared with metoprolol(p = 0.015) and nitroglycerin (p = 0.001) among groups. Although neither lidocaine nor metopro-lol had any difference on pain management when applied from antecubital or dorsal hand vein(p > 0.05), nitroglycerin injection from antecubital vein had demonstrated statistically lowerpain scores (p = 0.001).CONCLUSION: We found lidocaine to be the most effective analgesic in decreasing propofolrelated pain. We therefore suggest iv lidocaine for alleviating propofol related pain at operations.

RESUMOJUSTIFICATIVA E OBJETIVOS: A dor no local da injeção após a administração de propofol é comum e pode causar desconforto nos pacientes. O objetivo deste estudo foi comparar a eficácia de nitroglicerina, lidocaína e metoprolol, aplicados intravenosamente através de veias do dorso das mãos ou antecubitais, para eliminar a dor causada pela injeção de propofol.MÉTODOS: Foram alocados em grupos 147 pacientes de acordo com o analgésico administrado: metoprolol (n = 31, Grupo M), lidocaína (n = 32, Grupo L) e nitroglicerina (n = 29, Grupo N). Os analgésicos foram aplicados via cateter intravenoso em veia do dorso da mão ou antecubital. A dor foi avaliada com uma escala de quatro pontos (0 = sem dor, 1 = dor leve, 2 = dor moderada, 3 = dor intensa) nos segundos cinco, 10, 15 e 20. Os dados demográficos dos pacientes, estado físico ASA, IMC, nível de escolaridade, efeito das vias de injeção e local das cirurgias foram analisados quanto a seus efeitos no escore total de dor.RESULTADOS: Não houve diferença entre os grupos em relação ao escore total de dor (p = 0,981). Não houve diferença no escore total de dor em relação ao estado físico ASA, escolaridade e local da cirurgia. No entanto, lidocaína foi mais eficaz em comparação com metoprolol (p = 0,015) e nitroglicerina (p = 0,001), na comparação entre os grupos. Embora lidocaína e metoprolol não tenham apresentado diferença no tratamento da dor quando aplicados em veia antecubital ou do dorso da mão (p > 0,05), a injeção de nitroglicerina em veia antecubital apresentou escores de dor estatisticamente menores (p = 0,001).CONCLUSÃO: Lidocaína mostrou-se como analgésico mais eficaz para diminuir a dor relacionada à injeção de propofol. Sugerimos, portanto, lidocaína IV para aliviar a dor relacionada à injeção de propofol em operações.

Tumor necrosis factor-α antagonists: Side effects and their management.

As elevated levels of tumor necrosis factor-alpha (TNF-α) are associated with disease severity in psoriasis and psoriatic arthritis, TNF-α antagonists are being used to treat moderate to severe disease in patients who have contraindications, fail to respond or develop side effects to conventional systemic therapies. It is of utmost importance to be well versed with the possible adverse effects and contraindications of TNF-α antagonists so that they can be used effectively and safely. Many of their adverse effects have been well studied in patients of rheumatoid arthritis (RA) and inflammatory bowel disease (IBD) and may not be completely applicable in psoriasis. This is because patients with RA and IBD are on multiple immunosuppressants while those with psoriasis are mostly receiving single systemic therapy and often have comorbidities that distinguish them from those with RA or IBD. Also, some of the side effects are still controversial and debated. Long-term prospective randomized controlled studies are needed to better understand the associated risk in patients of psoriasis. Baseline screening and periodic monitoring during treatment can reduce and help in early identification and appropriate management of the adverse outcomes. This article reviews the side effects known to be associated with TNF-α antagonists, their pathomechanisms and management guidelines. Some of the common side effects include infusion and injection site reactions, infections particularly reactivation of tuberculosis, autoantibody formation and drug induced lupus erythematosus, liver function abnormalities, hematological, and solid organ malignancies.

At present, some teenagers and young people in Cuba, in their desire to quickly increase the size of their muscles, are injecting soybean oil for domestic use, which has led them to serious injuries and even risk to their lives. The aim of this work is to present this new condition, to show the characteristics of the lesions and spread the results for education and prevention. We presented three cases on the adverse effects of oil injection into muscles in patients who were admitted to the Paediatric Hospital Eliseo ¨Noel¨ Caamaño of Matanzas from December 2010 to May 2011. Their clinical features were a high increase in volume of the injected muscles, heat, redness, intense pain and functional impotence with general malaise. The surgical treatment consisted on the incision, debridement and drainage which showed abundant oil, pus, blood and necrotic muscle fibres, procedure that had to be performed many times. The lesions did not occur immediately, but with varying intervals and not in unison but in a disorganized form with great difficulty in healing. Treatment with broad-spectrum antibiotic was also used as well as hyperbaric chamber. We conclude that the use of domestic oil provokes serious consequences to health such as sepsis and serious muscle necrosis, Hepatitis C, septicaemia and danger to the lives of those who use it(AU)

Unsafe injection practices in Hodeidah governorate, Yemen

Unsafe injection practices are a major public health problem and can lead to the transmission of blood borne pathogens, including hepatitis B virus [HBV], hepatitis C virus [HCV] and human immunodeficiency virus [HIV]. The present study was conducted to determine the nature and magnitude of unsafe injection practices in healthcare facilities in Hodeidah governorate, Yemen. The study was conducted in two hospitals and a representative sample of the governorate's health centers. A total of 1600 injections were observed in these facilities. This study revealed several unsafe practices, particularly the recapping of needles after use, which occurred in 61.1% and 36.8% of the observations in the hospitals and the health centers, respectively. This study showed that most healthcare workers [HCWs] followed the proper injection protocols but performed some procedures that exposed themselves and the community to the risk of needlestick injuries [NSIs] and blood borne infections

Descemet's tear due to injector cartridge tip deformity.

Foldable intraocular lens (IOL) implantation using an injector system through 2.8-mm clear corneal incision following phacoemulsification provides excellent speedy postoperative recovery. In our reported case, a Sensar AR40e IOL (Abbott Medical Optics, USA) was loaded into Emerald C cartridge, outside the view of the operating microscope, by the first assistant. The surgeon proceeded with the IOL injection through a 2.8-mm clear corneal incision after uneventful phacoemulsification, immediately following which he noted a Descemet's tear with a rolled out flap of about 2 mm near the incision site. Gross downward beaking of the bevelled anterior end of the cartridge was subsequently noticed upon examination under the microscope. We suggest careful preoperative microscopic inspection of all instruments and devices entering the patient's eyes to ensure maximum safety to the patient.

Can ephedrine pretreatment be effective in alleviating rocuronium injection pain?

The aim of this randomized, double-blind, placebo-controlled study was to evaluate the effect of ephedrine pretreatment on the intensity of rocuronium injection pain when rocuronium was applied by timing principle and also to compare this effect with lidocaine and placebo. 120 American Society of Anesthesiology risk score I-II patients scheduled for elective surgery under general anesthesia were randomized into three groups to receive either 70 micro g/kg ephedrine [ephedrine group, n = 40] or 0.5 mg/kg lidocaine [lidocaine group, n = 40] or 5 ml NaCl 0.9% [placebo group, n = 40] as pretreatment. Thirty seconds after pretreatment drugs, rocuronium 0.6 mg/kg was administered by the timing principle and rocuronium injection pain scores were recorded. Twenty seconds after rocuronium administration, anesthesia was induced with thiopental and the patient's trachea was intubated. Hemodynamic parameters and adverse effects were recorded. The overall frequency of having pain was 82.5, 52.5 and 22.5% in placebo, ephedrine and lidocaine groups, respectively. Although the frequency of mild and moderate pain scores was higher in the ephedrine group than in the lidocaine group, this difference was not statistically significant [p = 0.032 and p = 0.001, respectively]. Although not as effective as lidocaine 0.5 mg/kg, 70 micro g/kg ephedrine pretreatment was able to alleviate rocuronium injection pain when rocuronium was applied by timing principle

Is palatal injection mandatory prior to extraction of permanent maxillary tooth: A preliminary study.

Introduction: Even after the invention of the modern injection techniques, palatal injection still remains a painful experience for patients, and this pain is attributed to the presence of rich nerve complement and displacement of palatal mucosa during anesthesia. Objective: The aim of the present study was to demonstrate if lidocaine HCl could provide palatal anesthesia if given buccally during maxillary tooth removal without the need for a palatal injection. Materials and Methods: The study group consisted of 75 patients, and 25 were controls. All the patients in the study group had unilateral extractions. In 75 patients, 2 ml of 2% lidocaine HCl with 1:80,000 epinephrine was injected into the buccal vestibule of tooth indicated for extraction without palatal injection. After 8 min, the extraction of maxillary tooth was carried out. Twenty-five subjects in the control group underwent same protocol with palatal injection. All the patients completed a faces pain scale (FPS) and a 100 mm visual analog scale (VAS) after extraction. Statistical Analysis Used: Unpaired t test and Chi-square test. Results: According to VAS and FPS scores, when comparison was carried out between permanent maxillary tooth removal with and without palatal injection, the difference in the pain levels were not statistically significant (P>0.05). Conclusion: The extraction of permanent maxillary tooth is possible by depositing 2 mL of lidocaine to the buccal vestibule of the tooth without the need for palatal anesthesia.

Peribulbar anesthesia for cataract surgery: Effect of lidocaine warming and alkalinization on injection pain, motor and sensory nerve blockade.

Aim: To compare self-reported pain and efficacy of warmed, alkalinized, and warmed alkalinized lidocaine with plain 2% lidocaine at room temperature for peribulbar anesthesia in cataract surgery. Materials and Methods: Through a prospective, single-blinded, randomized, controlled clinical trial 200 patients were divided into four groups. They received either lidocaine at operating room temperature 18°C, control group (Group C), lidocaine warmed to 37°C (Group W), lidocaine alkalinized to a pH of 7.09 ± 0.10 (Group B) or lidocaine at 37°C alkalinized to a pH of 6.94 ± 0.05 (Group WB). All solutions contained Inj. Hyaluronidase 50 IU/ml. Pain was assessed using a 10-cm visual analog score scale. Time of onset of sensory and motor blockade and time to onset of postoperative pain were recorded by a blinded observer. Results: Mean pain score was significantly lower in Group B and WB compared with Group C (P < 0.001). Onset of analgesia was delayed in Group C compared with Group B (P = 0.021) and WB (P < 0.001). Mean time taken for the onset of complete akinesia and supplementation required for the block was significantly lower in Group B. Time of onset of pain after operation was significantly earlier in Group W compared with Group C (P = 0.036). Conclusion: Alkalinized lidocaine with or without warming produced less pain than lidocaine injected at room temperature. Alkalinization enhances the effect of warming for sensory nerve blockade, but warming does not enhance alkalinization, in fact it reduces the efficacy of alkalinized solution for blocking the motor nerves in the eye.

Dental anxiety among university students and its correlation with their field of study

Objective: This study was designed to investigate the subjective ratings of dental anxiety levels among university students enrolled at Jordan University of Science and Technology. In addition, the present study aimed to explore the sources of dental anxiety and the impact of gender on the perceived dental anxiety and the correlation between field of study and dental anxiety level.Material and Methods: The Modified Corah Dental Anxiety Scale was used to measure dental anxiety among the study population. Six hundred subjects were recruited into the study from Jordanian undergraduate students from the faculties of Medicine, Engineering, and Dentistry. Results: Five hundred and thirty five complete questionnaires were returned, which accounts for a response rate of 89.2%. The totals of the mean anxiety scores were the following: Medical students, 13.58%; Engineering students, 13.27% and dental students, 11.22%. About 32% of the study population has scored 15 or more. Dental students had the lowest percentage of those who scored 15 or more. Surprisingly, the medical students were responsible for the highest percentage of those who scored 15or above. Although women demonstrated statistically higher total dental anxiety scores than men (p= 0.03), the difference between both genders was small and could be clinically insignificant. The students were anxious mostly about tooth drilling and local anesthetic injection. Conclusion: Lack of adequate dental health education may result in a high level of dental anxiety among nondentaluniversity students in Jordan. Further studies are required to identify the correlates of dental anxiety among university students.

Propofol in an emulsion of long chain triglyceride and medium-long chain triglyceride: the effect on pain during injection

Pain on injection is major disadvantage of standard propofol formulated with long chain triglycerides [LCT] during induction of anesthesia and sedation in critically ill patients. It is found that concentration of free propofol in aqueous phase of emulsion is responsible for pain on injection and that reducing amount of free propofol would also reduced frequency and intensity of pain on injection. The study was design to investigate whether pain on injection can be reduced by new formulation of propofol which consist of medium chain and long chain triglycerides [MCT/LCT] which is now available in market, and claimed reduced concentration of free propofol in aqueous phase. We devised a prospective, analytical; double blind randomized study to compare the pain on injection of two formulation of propofol for induction of general anesthesia. The present study included 200, non premeditated ASA I, II - adult patients scheduled for elective surgery under general anesthesia at Abbasi shaheed hospital. Patients were allocated randomly in two groups to receive either propofol - MCT/LCT [group I] or propofol - LCT [group II]. The study solution injected at speed of 1ml/sec in a dose of 2.5 mg /kg for induction of general anesthesia and patients graded any associated pain on injection using four point scale: 0= no pain, 1= mild pain, 2= moderate pain, 3= severe pain. There was a significantly less incidence and intensity of injection pain in group-I compared with group-II. The author concluded that propofol MCT/LCT significantly reduced the incidence and severity of pain on injection

Técnica para injeção intravítrea de drogas no tratamento de doenças vítreorretinianas / Technique of intravitreal drug injection for therapy of vitreoretinal diseases

A injeção intravítrea é atualmente a técnica mais utilizada no tratamento de várias doenças vítreorretinianas. Neste artigo serão discutidas a técnica e complicações da injeção intravítrea de drogas no tratamento de doenças vítreorretinianas. Em resumo, a técnica envolve várias etapas. Inicialmente dias antes da injeção pode-se realizar aplicação de antibióticos e acetazolamida para prevenção de infecção e redução da pressão intra-ocular. Antes do procedimento deve-se dilatar a pupila e executar anestesia tópica com colírios ou gel anestésico. A antissepsia pré-operatória envolve aplicação de colírios de iodo-povidona 5 por cento no fundo de saco conjuntival ao menos 10 minutos antes do procedimento. A injeção deve ser realizada no centro cirúrgico com uso de luvas estéreis e máscara pelo cirurgião. O olho deve ser exposto com blefarostato estéril, e proteção com "sterile-drape" para evitar contato entre a agulha e pálpebras/cílios. A agulha deve ser posicionada no momento da injeção a 3,5 - 4 mm do limbo, e leve mobilização da conjuntiva com um cotonete estéril ou uma pinça facilitam a penetração da agulha através da conjuntiva e esclera. A agulha deve ser inserida gentilmente para dentro da cavidade vítrea até 6 mm de profundidade. Imediatamente após a injeção o paciente deve ser examinado por técnica de oftalmoscopia binocular indireta. Caso a acuidade visual seja ausência de percepção luminosa ou oclusão vascular arterial retiniana seja observada, terapias para diminuição da pressão como paracentese na camada anterior ou massagem por oculopressão diretamente sobre o globo ocular devem ser imediatamente tomadas. A alta ambulatorial deve ser realizada quando o cirurgião estiver ciente da ausência de complicações intra-operatórias; o paciente deverá sair do centro cirúrgico com curativo oclusivo. O paciente deve ser submetido a exame oftalmológico completo no primeiro dia pós-operatório quando associação de antibióticos com corticosteróides...

Intravitreal injections are the standard technique applied in the treatment of some vitreoretinal diseases. In this paper the technique and complications of intravitreal injections are presented. In summary, the procedure involves various consecutive steps. Initially, days before the treatment topical antibiotics and acetazolamide may be prescribed for reduction of the ocular flora and intraocular pressure. Before the injection, the pupil should be dilated and topical anesthesia should be achieved. Injection shall be performed in the operating room under sterile conditions, the surgeon should wear surgical gloves and mask. The eye is then exposed with sterile blepharostat and sterile-drape thereby providing protection of the needle against the contact with contaminated lashes and lids. Injection is done 3.5 mm from the limbus through the pars plana. The needle should be inserted up to 6 mm into the vitreous cavity. Immediately after injection the patient must be examined by indirect ophthalmoscopy to verify central artery perfusion and complications as vitreous hemorrhage. Visual acuity better than light perception should be detected right after injection. If persistent central retinal artery occlusion is diagnosed, anterior chamber paracentesis should be performed. The patient may be discharged with an occlusive patch. Examination at the first postoperative day should exclude various complications such as endophthalmitis, and topical steroid and antibiotics should be prescribed for 7 days. Some complications encountered after intravitreal injections include retinal detachment, vitreous hemorrhage, cataract, uveitis, ocular hypertension, or endophthalmitis.

Comparison of two pain scales in Indian children.

OBJECTIVE: To compare the faces pain scale and color analogue scale among children aged 6-12 years undergoing selected procedures (venipuncture, intravenous cannulation, intramuscular injection, lumbar puncture, bone marrow aspiration) and to compare the procedural pain in a child as perceived by the child, parents and health care professionals using the above mentioned scales. METHODS: This was a prospective, descriptive correlational study of children aged 6-12 years, who had undergone selected procedures. Children were assessed for their pain severity using Faces Pain Scale and Color Analogue Scale. Parents and health care professionals also independently assessed the child's pain using the same scales. RESULTS: 181 children who fulfilled the eligibility criteria were enrolled in the study. There was a significant positive correlation (R = >0.8) between both the pain scales. There was fair to moderate positive correlation (R = 0.29 to 0.58) of pain perception of child with parents and health care professionals. CONCLUSIONS: Faces Pain Scale and Color Analogue Scales seem to be appropriate instruments for measuring pain intensity among Indian children aged 6-12 years undergoing selected procedures.

Acute orbital abscess complicating deep posterior subtenon triamcinolone injection.

A 54-year-old diabetic female presented with orbital abscess and corneal infiltrate 3 days after deep posterior subtenon triamcinolone acetonide injection in her right eye. This was administered immediately after focal laser photocoagulation for diabetic macular edema. The orbital abscess and corneal infiltrate responded to systemic and topical antibiotics.

Descemet's membrane detachment caused by inadvertent vancomycin injection.

Descemet's membrane detachment is a condition with a wide range of etiologies. The most common cause is a localized detachment occurring after cataract surgery. We report a case of vancomycin injection-induced Descemet's membrane detachment as a complication following a routine cataract surgery and its management.

Primary cutaneous actinomycosis: a rare soft tissue infection.

Actinomycosis caused by Actinomyces spp. is a chronic and suppurative infection caused by an endogenous gram positive bacterium. The unusual sites of infection are the head and neck, thorax and abdomen and are almost always endogenous in origin. Primary cutaneous actinomycosis is very rare and is usually associated with external trauma and local ischemia. We report a case of a primary cutaneous actinomycosis of the thigh in a 30-year-old man. The patient acquired the infection through an injection wound which progressed to multiple discharging sinuses. Clinical material from the wound demonstrated the presence of Actinomyces in smears and cultures. The patient was diagnosed and successfully treated with surgical resection and combined antibiotic therapy.

Evaluation of 19 cases of inadvertent globe perforation due to periocular injections.

BACKGROUND: Inadvertent globe perforation due to periocular injection is a serious iatrogenic complication. AIM: To study risk factors, management and visual outcome of inadvertent globe perforation during periocular injection, in cases referred to a tertiary eye care center. DESIGN AND SETTING: Retrospective study at a tertiary referral center with a single investigator. MATERIALS AND METHODS: Nineteen consecutive cases with a clinical diagnosis of globe perforation were studied (1998-2004). Clinical setting, risk factors, clinical presentation, management and visual outcome were analyzed. RESULTS: Retrobulbar injections 6 (32%), peribulbar injections 10 (53%) and subconjunctival injections 3 (16%) were responsible for inadvertent globe perforation. Anesthetists accounted for 6 (32%) injections and 13 (69%) were referred from high volume community settings. Anesthetists identified the mishap on the table in 17% (1 out of 6) of cases and the ophthalmologists in 69% (9 out of 13) myopia was present in 10 (53%). Breaks were located inferotemporally in nine eyes. Four underwent laser and cryopexy, 14 (74%) underwent vitreous surgery. Visual acuity greater than 20/200 was achieved in 12 patients. CONCLUSION: Myopia was found to be a significant risk factor. Inferotemporal breaks were common. Anesthetists were more likely to miss this complication when it occurred. In this series, intervention salvaged vision in a significant number of eyes.
