Safe administration of noradrenaline by the peripheral route: A systematic review. / Administración segura de noradrenalina por vía periférica: una revisión sistemática.

PURPOSE: To review and analyze the available literature on peripheral administration of noradrenaline (NA) with the aim of providing recommendations to ensure correct use and patient safety. METHODS: Systematic review on the databases PubMed, ISI Web of Science, SCOPUS and Science Direct, using the following search terms: ("Noradrenaline" [Mesh]) AND ("Norepinephrine" [Mesh]) AND ("Vasopressors" [Mesh]) AND ("Peripheral infusions" [Mesh]) OR ("Extravasations" [Mesh]). A total of 1,040 articles were identified. Animal studies and studies written in languages other than English were excluded. Finally, 83 articles were included. RESULTS: NA can be administered peripherally. The risk of extravasation should be taken into account, with phentolamine being the first pharmacological line of treatment. It has also been related to the appearance of thrombophlebitis, cellulitis, tissue necrosis, limb ischemia and gangrene, although its incidence seems to be low. The use of peripheral NA in children seems to be carried out without obvious complications. The use of standard concentrations is suggested to reduce the risk of errors. It is recommended to use 0.9% saline as the default diluent for peripheral NA. CONCLUSIONS: Peripheral infusions of NA could be a safe and beneficial option in early resuscitation provided that a number of guidelines are followed that reduce the likelihood of complications associated with this route.

Relative bioavailability of fedratinib through various alternative oral administration methods in healthy adults.

Fedratinib is an oral Janus kinase 2-selective inhibitor for the treatment of adult patients with intermediate-2 or high-risk myelofibrosis; however, some patients have difficulty with oral dosing. This randomized, phase 1, open-label, 2-part crossover study evaluated the relative bioavailability, safety, tolerability, taste, and palatability of fedratinib resulting from various alternative oral administration methods in healthy adults. Participants could receive fedratinib 400 mg orally as intact capsules along with a nutritional supplement; as contents of capsules dispersed in a nutritional supplement, delivered via nasogastric tube; or as a divided dose of 200 mg orally twice daily as intact capsules with a nutritional supplement. Fifty-eight participants received treatment. Total exposure to fedratinib was similar after oral administration of intact capsules or when dispersed in a nutritional supplement (area under the plasma concentration-time curve from time 0 to the time of the last quantifiable concentration geometric mean ratio [AUC0-t GMR] [90% CI], 1.007 [0.929-1.092]). Total exposure to fedratinib was slightly reduced following nasogastric administration (AUC0-t GMR 0.850 [0.802-0.901]) and as a divided dose (AUC0-t GMR 0.836 [0.789-0.886]). No new safety signals were identified for fedratinib, and most participants found the taste and palatability acceptable when dispersed in a nutritional supplement. Overall, results suggest no clinically meaningful differences in total exposure to fedratinib between the tested oral administration methods. These findings may facilitate administration of fedratinib to patients who are intolerant of swallowing the capsule dosage form. (ClinicalTrials.gov: NCT05051553).

Prevention of vasculitis and vascular pain by side route administration of vinorelbine: A case report.

A 49-year-old female with non-small-cell lung cancer was placed on adjuvant chemotherapy with vinorelbine (25 mg/m2: Day 1.8) and cisplatin (80 mg/m2: Day 1). The simultaneous intravenous infusion of vinorelbine from the side route and 500 mL of saline from the main route successfully prevented vasculitis and vascular pain.

Systemic, Intrathecal, and Intracerebroventricular Antihyperalgesic Effects of the Calcium Channel Blocker CTK 01512-2 Toxin in Persistent Pain Models.

CTK 01512-2 toxin is a recombinant peptide of the Phα1ß version derived from the venom of the Phoneutria nigriventer spider. It acts as an N-type voltage-gated calcium channel (VGCC) blocker and shows a prolonged effect on preventing and reducing nociception. Herein, CTK 01512-2 was tested on two models of persistent pain, the chronic post-ischemia pain (CPIP) and the paclitaxel-induced peripheral neuropathy, to evaluate its systemic, intrathecal, and intracerebroventricular effects on mechanical hypersensitivity and thermal allodynia. Glial cell viability was also investigated using the MTT test. The results showed that CTK 01512-2 intrathecal and systemic treatments reduced the mechanical hypersensitivity induced by CPIP, mainly between 1-4 h after its administration. Additionally, intrathecal treatment reduced the CPIP-induced thermal allodynia. In its turn, the intracerebroventricular treatment showed mechanical antihyperalgesic and thermal antiallodynic effects in the paclitaxel-induced peripheral neuropathy. These data reinforce the therapeutic potential of CTK 01512-2 to treat persistent pain conditions and offer a perspective to use the systemic route. Moreover, CTK 01512-2 increased the glial cell viability in the MTT reduction assay, and it may indicate a new approach to managing chronic pain. The results found in this study help to pave new perspectives of pain relief treatments to patients affected by chronic pain.

Benefits of Intranasal Administration of Diamorphine and Midazolam in the Management of Patients Receiving Palliative Care in the Community: A Case Series.

Opioids and benzodiazepines are cornerstones of the pharmacological management of pain and agitation in palliative medicine. Oral drug delivery is the most popular route of administration, with the subcutaneous route typically utilized where oral medications are not tolerated or are ineffective. Intranasal drug delivery offers an important alternative administration route, with benefits including ease of administration, tolerability and avoidance of needle use, and is particularly useful in the community, where medications may be administered by lay carers or by patients themselves. Intranasal diamorphine and intranasal midazolam both have demonstrated efficacy and safety in adult and pediatric cohorts, however there is limited research into their use in managing pain and agitation in palliative care. We describe the management of three patients under the community palliative care team who received intranasal diamorphine, two of whom also received intranasal midazolam, to manage breakthrough symptoms of pain and agitation at home. In each case, the patient or their relative was taught how to prepare and administer the relevant intranasal medication. This case series demonstrates that for selected patients, diamorphine and midazolam administered intranasally by patients or lay carers at home is efficacious, acceptable and generally well tolerated.

[Prescription of phosphorus, calcium and magnesium: Choice of the millimole unit to establish the equivalence of doses between oral and injectable forms]. / Prescription de phosphore, calcium et magnésium : choix de l'unité millimole pour établir l'équivalence des apports entre les formes orales et injectables.

OBJECTIVES: Information available on the packaging of drugs indicated for patients electrolytes replenishment differs from one manufacturer to another. They relate, for example, the unit chosen to express elemental electrolyte concentration. These differences constitute a risk factor for medication errors. This article proposes a clinical decision support tool which defines dose equivalences between the oral and injectable formulation galenic forms for medications providing phosphorus, calcium and magnesium and a calculated replenishment ratio. METHODS: The amounts of elemental electrolyte were determined from the information contained on the packaging and the summaries of product characteristics. Only the specialties of our hospital drug formulary were studied. For each element, the replenishment ratio was determined from published data. RESULTS: Equivalence tables were created for the phosphorus, calcium and magnesium between oral and injectable formulation. A clinical decision support tool was developed from these data. CONCLUSION: The use of this tool is a first way to reduce the risk of medication errors. It remains to determine the conditions for its dissemination and evaluation. This issue raises the questions of the exclusive use of the millimole unit on packaging and for prescription, and that of the integration of this type of tool into prescription software and decision support systems.

Physical Compatibility of Nafamostat with Analgesics, Sedatives, and Muscle Relaxants for Treatment of Coronavirus Disease 2019.

BACKGROUND: Severe coronavirus disease 2019 (COVID-19) may require continuous administration of analgesics, sedatives, and muscle relaxants. Nafamostat has recently been reported as a therapeutic agent for COVID-19. However, there is a lack of information on the compatibility of nafamostat with the aforementioned drug classes. This study evaluated the physical compatibility of nafamostat with these drug classes. METHODS: Nafamostat was combined with 1-3 target drugs (fentanyl, morphine, midazolam, dexmedetomidine, and rocuronium). Fifteen physical compatibility tests were conducted. Nafamostat was dissolved in 5% glucose solution; the final concentration was 10 mg/mL. All other medications were diluted in 0.9% sodium chloride to obtain clinically relevant concentrations. The power of hydrogen (pH) of all medications was measured during each test. Compatibility tests were conducted with 4 test solutions in which nafamostat and the target drugs were compounded at equal volume ratios (1:1, 1:1:1, or 1:1:1:1). Visual appearance, turbidity, and pH were evaluated immediately after mixing and at 1 and 3 hours. Physical incompatibilities were defined as gross precipitation, cloudiness, appearance of the Tyndall effect, or a turbidity change of ≥0.5 nephelometric turbidity units (NTU) based on nafamostat. RESULTS: The mean pH of nafamostat was 3.13 ± 0.03. The combination of nafamostat, fentanyl, and dexmedetomidine had the highest pH (3.39 ± 0.01; 3 hours after mixing). All drugs were compatible with nafamostat until 3 hours after admixture, with a mean turbidity value of ≤0.03 NTU. CONCLUSIONS: Infusions combining nafamostat with the tested sedatives, analgesics, and muscle relaxants could be safely administered.

Patient compliance with new oral anticoagulants after major orthopaedic surgery: rivaroxaban and dabigatran compared with subcutaneous injection of fondaparinux.

PURPOSE: the main purpose of our study was to compare patient compliance with the orally administered new oral anticoagulants (NOCs) dabigatran and rivaroxaban compared with subcutaneously injected fondaparinux after major orthopaedic surgery, and to assess patient preference for the oral vs subcutaneous administration route. METHODS: prophylactic antithrombotic drug therapy with dabigatran (group D; GD, n=32 patients), rivaroxaban (group R; GR, n=38 patients) or fondaparinux (group F; GF, n=30 patients), to prevent deep vein thrombosis, was started immediately after surgery in 100 patients submitted to total hip arthroplasty. RESULTS: the patients had a mean age of 68.7±11 years and 62% were female. In GD, 87.5% of patients indicated that they preferred oral intake of medications to subcutaneous injection (12.5%). In GR, 84.2% declared a preference for oral administration over subcutaneous injection (15.8%). In GF, a surprisingly high proportion of patients (73.3%; p < 0.001) declared that they preferred subcutaneous administration of medications over the oral route (26.7%). Overall, the rate of compliance with antithrombotic drug therapy was very high, at 99%. CONCLUSIONS: intake of the NOAs dabigatran and rivaroxaban following hospital discharge is entirely the responsibility of the patient; a high level of patient compliance with these drugs must therefore be demonstrated in order for them to become well accepted within the medical community. The results of this study showed a very high level of compliance both with orally and subcutaneously administered drugs. LEVEL OF EVIDENCE: Level I, randomized clinical study.

Effects of Hormone Therapy on Serum Lipid Levels in Postmenopausal Korean Women.

OBJECTIVES: This study was conducted to examine the effects of hormone therapy on serum lipid levels in postmenopausal Korean women. METHODS: This retrospective cohort study included 154 healthy postmenopausal Korean women. Seventy-nine women took oral estrogen (conjugated equine estrogen 0.625 mg/day or equivalent), and 75 applied estrogen transdermally using 0.1% 17ß-estradiol gel. Micronized progesterone (MP) was added to 40 women of oral group and 49 women in transdermal group. Serum levels of triglyceride, low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), and lipoprotein (a) were measured before, 3 and 6 month after hormone therapy. RESULTS: At baseline, mean body mass index (BMI) were lower (22.76 vs. 23.74 kg/m(2)) and proportion of family history of cardiovascular disease (CVD) (61 vs. 39%) were higher in oral group. In oral group, LDL-C and lipoprotein(a) levels decreased, and triglyceride and HDL-C levels increased significantly after 3 and 6 months. There was no significant change in lipoprotein levels compared to the baseline in transdermal group. There were also no differences with additional MP. Changing pattern of HDL-C during 6 months was significantly different by the route of estrogen administration. CONCLUSION: Oral estrogen therapy might be more beneficial than transdermal estrogen in terms of lipid in postmenopausal Korean women. The estrogen effects are not influenced by adding MP.

Investigação da técnica de administração de medicamentos por sondas enterais em hospital geral / Investigation of the technique of medication administration through enteral feeding tubes in a general hospital / Investigación de la técnica de administración de medicamentos por sondas enterales en hospital general

A administração de fármacos por sondas enterais é uma prática cotidiana nos hospitais indicada para pacientes com transtornos de deglutição. O objetivo do estudo foi verificar a técnica empregada pela equipe de enfermagem no preparo e administração de medicamentos por sondas enterais em hospital geral de Dourados, MS. Tratou-se de estudo exploratório e descritivo realizado entre agosto de 2004 e maio de 2005. Como método, realizou-se a observação não-participante e direta das técnicas de administração, entrevista estruturada e análise dos prontuários. Constatou-se que 78,26% dos medicamentos foram administrados por sonda nasogástrica nas 23 situações observadas. Cerca de 97% dos fármacos estavam em formas farmacêuticas sólidas, tendo que passar por processo de derivação. Foram observados erros no preparo e administração, como trituração de comprimidos de liberação controlada, administração ao mesmo tempo de mais de um medicamento e associação do medicamento com a dieta enteral, levando à possível redução do efeito farmacológico.

The administration of drugs through enteral feeding tubes is an everyday practice in hospitals and indicated for patients with swallowing disorders. The aim of the study was to ascertain the technique applied by the nursing team in preparing and administering drugs through enteral feeding tubes in a general hospital in Dourados, Mato Grosso do Sul State. This exploratory and descriptive study was conducted between August 2004 and May 2005. The method used was non-participant, direct observation of the administration techniques, structured interview and chart analysis. In the 23 situations observed, 78.26% of the medication was administered through nasal-gastric tubes. About 97% of the drugs were in solid pharmaceutical form and required manipulation before application. Mistakes were observed in preparation and administration, such as grinding of time release tablets, administration of more than one medication at the same time and association of medication with enteral diet, leading to possible reduced pharmacological effect.
