Background: Amiodarone-induced anaphylaxis is seldom reported. The mechanism of this anaphylaxis is unknown. Methods: A literature search was carried out with keywords "Amiodarone" and "Anaphylaxis" and "polysorbate 80" or "hypotension." A search using "amiodarone" in the FDA Adverse Event Reporting System (FAERS) from 1969 to 2024 was also conducted. Results: There are a total of 10 cases of amiodarone-induced anaphylaxis in the literature. Six patients were male. Ages ranged from 15 to 86 years old. Nine cases were triggered by intravenous injection (IV) and one by oral administration. Eight patients did not have previous exposure to amiodarone. The trigger times for IV amiodarone were immediate to 90 minutes. All nine cases of IV amiodarone resulted in hypotension (90%), with an immeasurable blood pressure (70%). Presentations included bronchospasm or a skin rash (60%), angioedema (40%), and unconsciousness (20%). Only one patient had a history of allergy to penicillin and sulfonamide. An amiodarone skin test was positive on one patient. Increased blood tryptase (4 cases), positive basophil activation test to amiodarone (2 cases), increased eosinophil count (1 case), and increased serum IgE (1 case) were reported. Amiodarone was terminated in 80% of the patients. Epinephrine, norepinephrine, antihistamine-1, or steroids were used to rescue patients. Four patients were intubated. All patients fully recovered. In the FAERS database, 89 cases of amiodarone-associated anaphylaxis were reported, resulting in 14 deaths. Conclusions: Solvent polysorbate 80, amiodarone, and iodide may contribute to amiodarone-induced anaphylaxis. Prompt treatment is the key to saving patients.

Background: Initiation of sacubitril-valsartan and mineralocorticoid receptor antagonists (MRA) during hospitalization for acute decompensated heart failure (ADHF) may be an ideal time to optimize guideline-directed medical therapy. However, there is limited research assessing the safety of combining these agents in the hospital. Methods: This was a multi-center, retrospective, propensity-score matched cohort study performed at 7 acute-care hospitals within a large health care system. All adult patients admitted with ADHF between January 1, 2019 to December 31, 2021 who received sacubitril-valsartan with MRA (MRA group) or without MRA (non-MRA group) and had a left ventricular ejection fraction (LVEF) < 40% were included in the study. Results: 220 patients were screened during the study time frame with 179 meeting inclusion criteria. Following propensity-score matching, 50 patients in the MRA group were matched to 50 patients in the non-MRA group. The overall incidence of adverse drug reactions (ADRs) was 24% in the non-MRA group compared to 20% in the MRA group (P = .629). There was a significantly greater incidence of hyperkalemia in the MRA group (0% vs 10%; P = .022). None of the patients in the non-MRA group were readmitted within 30 days due to an ADR compared to 6% in the MRA group (P = .079). Conclusion: The addition of spironolactone to sacubitril-valsartan in the hospital setting following stabilization of ADHF did not lead to a significantly greater incidence of overall ADRs, but patients were more likely to develop hyperkalemia and there was a numerically higher incidence of 30-day readmissions due to ADRs.

Background: Currently, irrational uses of medicines becoming global problem largely in developing countries like Ethiopia. Inappropriate prescribing is a major cause for poor treatment outcome and higher costs. Hence, this study was aimed to investigate medicine prescribing practice and prescription errors using WHO medicine-utilization core indicators. Methods: A hospital based retrospective cross sectional study design was used to evaluate prescribing practices and prescription errors from September to October, 2024 at the OPD pharmacy using systematic random sampling technique while a prospective approach was employed for facility indicators. Presence of potential drug-drug interactions (DDIs) were evaluated using Medscape Online Drug Interaction Checker. Data were analyzed using SPSS version 25 and interpreted as tables and figures. Results: A total of 1019 medicines were prescribed in 524 prescriptions and 81.6% (n = 832) were actually dispensed. The percentage of antibiotic, injections and medicine prescribed from Essential Drug List was 33.9% (n = 345),3.5% (n = 36) and 92.3% (n = 941) respectively. The most frequently prescribed class of medicine were antibiotics 33.9% (n = 345). 65.1% (n = 341) were ≥2 medicines and 8.3% (n = 85) had at least one potential DDIs. Among overall DDIs, the monitor closely and serious level was 60% (n = 51) and 11.8% (n = 10) respectively. The average prescription error was 4.3. Prescription errors due to failure to mention diagnosis was 40.6% (n = 213). Conclusion: Based on findings, the prescribing practices had defects to the optimum value recommended by WHO and showed high prescription errors. Antibiotics prescribing was the major problem in practice. Remarkable DDIs were observed in prescribed medicines. Therefore, designing and implementing policy to improve medicine use practice is highly indispensable.

Introduction: Methotrexate (MTX) is a common medication used to treat rheumatoid arthritis (RA). MTX inhibits rapid cell turnover throughout the body which can lead to significant side effects. Patients who present with oral lesions may have suffered severe acute toxicity from MTX. Supportive pain treatment includes magic mouthwash solution and/or oral viscous lidocaine to manage pain and allow for healing. We report a case of MTX induced oral mucositis that did not respond to magic mouthwash but did improve with a morphine mouthwash solution. Case: A 67-year-old female with RA presented with worsening oral lesions over 2 weeks. She reported non-compliance with folic acid for 2 weeks while on MTX. Physical exam revealed ulcerating oral lesions on the mucous membranes consistent with mucositis. Pain treatment was initiated with magic mouthwash, but her pain was not well controlled after 24 hours, and still unable to swallow. An oral morphine mouthwash solution was initiated, and patient reported improved pain control over the next 48 hours. She was on the morphine mouthwash for 6 days during which improvement in the lesions was noted. Discussion: Pain management is imperative for oral mucositis. When traditional therapies do not provide adequate control, morphine mouthwash can be considered. It is a safer alternative to systemic opioids and topical opioids may influence cell proliferation and migration, which can positively impact healing of oral lesions. Conclusion: A morphine mouthwash solution can provide effective pain management for oral mucositis lesions in patients who do not respond adequately to magic mouthwash.

Carbamazepine is utilized for various indications. Due to its pharmacokinetic profile and drug properties, toxicity can be delayed and persistent despite supportive care. We report a severe case of intentional carbamazepine toxicity in a carbamazepine naive individual mimicking brain death that was not diagnosed until three days after consumption of carbamazepine when the patient was comatose. Symptoms of overdose persisted for several days despite attempted treatment with activated charcoal and whole bowel irrigation, hemodialysis, and plasmapheresis. Symptoms only began to improve with bowel evacuation as a result of administration of neostigmine intravenously plus hemodialysis and plasmapheresis additionally. Despite previous literature that reported success with hemodialysis and/or plasmapheresis we did not find either to be overly effective in our case possibly due to lack of ability to perform multidose activated charcoal and whole bowel irrigation. To our knowledge this is one of the few cases of carbamazepine overdose utilizing both hemodialysis and plasmapheresis but without activated charcoal and the only case report in which neostigmine was administered as an attempt to remove drug via the gastrointestinal tract with success.

This research aims to summarize and discuss issues related to psychiatric drugs by using the classification system of the Pharmaceutical Care Network Europe (PCNE) and to provide a reference for the development and direction of clinical pharmacists' work in the future. Psychiatric patients who were hospitalized in our hospital from Janurary 2023 to December 2023 were enrolled. Drug-related problems (DRPs) were evaluated using the PCNE classification system (version 9.0). The types, causes, intervention plans, acceptance of intervention plans, and statuses of DRPs were analyzed. A total of 362 patients were included, covering 405 DRP cases, with an average DRP of 1.12 for each patient. All 405 DRP cases underwent interventions, with a success rate of 83.46%. The main categories of related drugs were psychotropic drugs (70.37%), anti-infective drugs (8.89%), and cardiovascular system drugs (5.19%). The main DRPs were possible adverse drug events (21.24%), poor treatment effects (69.14%), and unnecessary medication treatment (9.63%). The main causes of DRPs were inappropriate drug selection (18.52%), inappropriate combinations of drugs (16.05%), and excessive drug dosage (13.58%). The PCNE classification system helps clinical pharmacists improve their ability to identify and solve DRPs faced by psychiatric departments, improve pharmaceutical care efficiency, and ensure rational drug use.

Background: The challenge with obtaining a best possible medication history (BPMH) post-surgery is the delay in clarifying medications due to decreased post-operative cognitive status and pain, which can lead to missed or late administration of medications. Studies have suggested that unintentional medication discrepancies at the time of admission are common in general medical patients. Objectives: To investigate if a pre-admission pharmacist completing BPMHs for adult elective surgery patients with planned overnight admission increases the proportion of patients with (i) a BPMH completed, (ii) medication reconciliation completed and (iii) all home medications charted correctly within 24 hours of admission. Methods: Patients in the pre-intervention group had a BPMH completed on admission as standard of care. Patients in the post-intervention group were contacted by the pre-admission pharmacist 1 to 3 business days prior to admission to complete a BPMH. The pre-admission pharmacist role was performed by a surgical ward pharmacist in addition to their daily workload. Descriptive statistics, Chi-squared test and Mann-Whitney U test were used to analyse the data. Results: The post-intervention group had more patients with a completed BPMH (47.2% vs 25.3%, P = .005), medication reconciliation (43.8% vs 15.5%, P = .0001) and all home medications charted correctly (36% vs 16.9%, P = .007) within 24 hours of admission compared with the pre-intervention group. Conclusion: The introduction of a pre-admission service utilising the surgical ward pharmacist increased the proportion of patients with a completed BPMH, medication reconciliation and home medications charted correctly within 24 hours of admission.

Background: Clostridioides difficile (C. difficile) is a leading cause of healthcare-associated infections. Using opioids while infected with C. difficile may hypothetically lead to reduced clearance of the organism and higher risk of progressing to severe or fulminant infection. Objective: The objective of this study was to determine if opioid use leads to worsening of C. difficile infection. Methods: This was a single-center, retrospective cohort study of patients with C. difficile infection. The primary endpoint was progression to severe or fulminant disease, defined as serum creatinine greater than 1.5 mg/dL or over 50% of baseline, white blood cells above 15,000 cells/mm³, shock requiring vasopressors, ileus, toxic megacolon, or vancomycin dose increase. Secondary outcomes included hospital length of stay and time to resolution of diarrhea. The groups were stratified based on average morphine milligram equivalents received during the treatment. Results: A total of 73 patients were included in the non-opioid group and 93 patients in the opioid group. The composite outcome occurred in 16 patients (21.9%) without opioids vs 26 patients (28.0%) with opioids; (P = 0.37). The average length of stay was 7.2 days without opioids and 9.3 days with opioids (P = 0.11) and the average time to resolution of diarrhea was 3.5 days without opioids and 5.5 days with opioids (P = 0.40). Conclusion: There was no significant difference in the rate of progression to severe or fulminant disease. There was a numerical trend towards increase in progression in patients who had opioids, primarily driven by those who had higher dosages of opioids used.

Background: Post-traumatic stress disorder (PTSD) and substance use disorder (SUD) frequently occur together. Serotonergic agents are preferred medications to treat PTSD, while bupropion is reserved due to limited evidence. Ongoing studies suggest bupropion may be effective for treating methamphetamine use disorder (MUD). Investigators aimed to evaluate if bupropion would confer benefit to patients with Diagnostic and Statistical Manual of Mental Disorders, Fifth edition diagnoses for PTSD and MUD compared to traditional pharmacotherapy. Methods: This report describes four patients with comorbid PTSD and MUD who had a positive response to medication regimens containing bupropion compared to non-bupropion regimens for their trauma symptoms. Investigators were able to compare this to a control group of 41 patients receiving serotonergic agents alone. Case Report: PTSD checklist-civilian scores at time of medication initiation, site discharge, and post-discharge in the bupropion and non-bupropion group were 77, 35, and 29, compared to 51 ± 15, 52 ± 20 and 53 ± 10, respectively. Rates of relapse, average time to relapse, and hospital utilization in the bupropion vs non-bupropion group were 25.0% vs 48.8%, 107 days vs 210 ± 191 days, and 0% vs 29.3%, respectively. Discussion: Use of bupropion showed a greater reduction in PTSD symptom severity and a lower frequency of methamphetamine relapse and hospital utilization. Though missing data limited inclusion of patients in all outcomes, quantitative data suggests benefit with bupropion in comorbid PTSD and MUD. Conclusion: This case series suggests the potential for earlier initiation of bupropion treatment in those with PTSD who have comorbid MUD.

Objective: We evaluated the impact of a methicillin-resistant Staphylococcus aureus (MRSA) nasal polymerase chain reaction (PCR) protocol on the vancomycin length of therapy (LOT) for skin and soft tissue infections (SSTIs). Design: Retrospective quasi-experimental pre- and post- MRSA nasal PCR protocol implementation study. Setting: Tertiary-care academic medical center in Jacksonville, Florida. Patients: Eligible patients received empiric vancomycin for SSTIs from January 1st to September 30th 2020 (pre-implementation group) and from January 1st to September 30th 2022 (post-implementation group). Intervention: The electronic health system software was modified to provide a best-practice advisory (BPA) prompt to the pharmacist upon order verification of vancomycin for patients with SSTIs. Methods: We reviewed patient records to determine the time from vancomycin prescription to de-escalation. The secondary outcomes were incidence of acute kidney injury (AKI), number of vancomycin levels collected, and hospital length of stay (LOS). Results: The study included 131 patients (pre-implementation, n = 86 and post-implementation, n = 45). There was no significant difference in vancomycin length of therapy (LOT) between implementation groups: mean LOT in days and standard deviation (SD) were 2.7 (1.9) and 2.6 (1.3), respectively, p-value 0.493. Of significance, in the post-implementation group, vancomycin LOT between patients with a negative and positive MRSA PCR were 2.3 (1.1) and 3.9 (1.6), p-value 0.006. There was no difference in secondary outcomes. Conclusion: The utilization of the MRSA nasal PCR to guide vancomycin de-escalation did not significantly change the vancomycin LOT, however in the post-implementation group there was a significant difference in vancomycin LOT between negative and positive MRSA PCRs.
