Background: Previous studies in Europe and the USA have reported a high prevalence of adverse drug reactions (ADRs), but data on local ADRs in Myanmar are sparse.
Objective: Our objective was to study ADRs in patients admitted to selected wards of Yangon General Hospital (YGH) and Yangon Specialty Hospital (YSH), Myanmar.
Methods: This was a prospective observational study in three hospital wards during the first quarter of 2019. Suspected ADRs were carefully investigated in a face-to-face interview with each patient and via review of clinical records. Patients transferred to other wards or discharged were followed-up by the researchers until day 28 after admission. ADRs were divided into those that (1) led to the admission and (2) occurred during the hospital stay or after discharge (up to day 28 after admission).
Results: A total of 65 ADRs were identified, with 47 (29.4%) of 160 patients experiencing at least one ADR. Among these, 16 (24.6%) had led to hospital admission and 49 (75.4%) occurred in 31 patients during their hospital stay. Of 160 patients, 21 had taken at least one herbal remedy and six of these developed an ADR. Five ADR-drug associations (hypokalaemia with methylprednisolone, increased transaminase levels with standard antituberculosis drugs, upper gastrointestinal bleeding with nonsteroidal anti-inflammatory drugs, constipation with tramadol, and increased transaminase levels with herbal remedies) represented 18 (27.7%) of the 65 ADRs in this study. According to the Schumock and Thornton preventability scale, more than half of these ADRs (35 [53.9%]) were preventable.
Conclusion: The present study highlights the existence of ADRs among patients attending these hospitals. The implementation of active pharmacovigilance in hospitals could be a helpful first step to improving the awareness of unwanted effects of medicines and patient safety, as well as a way to strengthen the national pharmacovigilance system in countries such as Myanmar.

Opioid Allergy Cross-Reactivity: A Retrospective Study Across Three Opioid Classes.

IgE-mediated opioid hypersensitivities, or true allergies, are rare and most adverse reactions to opioids can be attributed to side effects or to pseudo-allergies. Given that immune-mediated allergies to opioids are uncommon, literature regarding cross-reactivity among opioid classes are limited. This retrospective study aimed to determine the rates of cross-reactivity and tolerance among patients with previously documented opioid allergy or adverse drug reaction (ADR) across three opioid drug classes (natural, semisynthetic, and synthetic opioids).

Introduction: Tuberculosis (TB) is the leading infectious cause of death globally. Despite WHO recommendations for TB preventive therapy (TPT), challenges persist, including incompletion of treatment and adverse drug reactions (ADRs). There is limited data on the 3-month isoniazid and rifapentine (3HP) pharmacokinetics, pharmacogenomics and their relation with ADRs.

Background: Reversible cerebral vasoconstriction syndrome (RCVS) is characterized by severe headaches, often thunderclap headaches, and a multifocal constriction of the cerebral arteries. Although RCVS can occur spontaneously, some cases occur after exposure to drugs. We describe the first case of RCVS in which methylphenidate, a drug with vasoconstrictive properties, is the only suspected drug.

Background: Excessive submental fat under the chin is a known aesthetic concern because of its negative impact on facial appearance and psychological well-being. AYP-101 is a newly developed injectable agent containing 93% soybean phosphatidylcholine (SPC) designed to reduce submental fat. We conducted a phase 1 study to evaluate the safety, pharmacokinetic (PK), and lipid profile effects of AYP-101.
