ReviewAn update on adverse drug reactions related to β-lactam antibiotics.
β-lactams have been consistently associated with the majority of drug-related adverse events. Generally, these are mild under proper dosing and judicious selection. ⋯ The currently available data denote that in addition to age, gender, co-morbidity, renal or liver function, and co-administered agents, the antibiotic levels rather than the dose itself seem to be associated with the emergence of adverse events. Most of them subside with time after withdrawal of the offending agent, but the number of cases resulting in chronic disabilities or even deaths in not negligible.

The nature, magnitude, and reporting compliance of device-related events for intravenous patient-controlled analgesia in the FDA Manufacturer and User Facility Device Experience (MAUDE) database.
The aim of this study is to determine the characteristics, magnitude, and the quality of reporting of mandated events involving intravenous patient-controlled analgesia (IV-PCA) devices in the Food and Drug Administration (FDA) Manufacturer and User Facility Device Experience (MAUDE) database; a postmarket surveillance system. ⋯ Patients on IV-PCA continue to experience serious complications as a result of preventable errors. Multi-modal interventions including educational training and the development and adoption of PCA devices with improved safety features are needed to improve safety.

Comparative Study Observational StudySuspected adverse drug reaction reports with oral anticoagulants in Portugal: a pharmacovigilance study.
In this pharmacovigilance study, we aimed to determine the incidence of spontaneously reported suspected adverse drug reactions (ADRs) related to oral anticoagulants: non-vitamin K antagonist oral anticoagulants (NOACs; apixaban, dabigatran, edoxaban, rivaroxaban) and vitamin K antagonists (VKA) Research design and methods: In this retrospective observational study, we extracted all the individual case safety reports related to oral anticoagulants recorded in the Portuguese Pharmacovigilance Database (January 2010 to April 2015). The annual incidence of suspected ADRs was estimated using drug exposure data. Disproportionality of reporting ADR was addressed through reporting odds ratio (ROR) and 99% confidence intervals. ⋯ Reporting of ADRs associated with oral anticoagulants (mainly NOACs), is increasing. Exploratory disproportion analyses showed an increase of reports of nervous system ADRs with NOACs, and INR-related ADRs with VKA.

Review Comparative StudyA review of clinical safety data for sumatriptan nasal powder administered by a breath powered exhalation delivery system in the acute treatment of migraine.
AVP-825 (sumatriptan nasal powder) is an FDA-approved intranasal medication delivery system containing low-dose sumatriptan powder for acute treatment of migraine with or without aura in adults. AVP-825 utilizes unique nasal anatomy features to avoid limitations of other intranasal delivery methods. Areas covered: Literature search terms: 'AVP-825', 'sumatriptan nasal powder', 'intranasal sumatriptan', 'sumatriptan safety', 'sumatriptan acute migraine'. ⋯ AVP-825 has the advantage of early efficacy onset associated with faster absorption at a lower delivered dose than liquid nasal spray or oral formulations. AVP-825 provided earlier efficacy (within 30 min) vs. 100 mg oral sumatriptan and similar sustained efficacy. AVP-825 offers the benefits of a non-oral, low-dose, tolerable acute migraine medication.

ReviewA narrative review of the safety concerns of deprescribing in older adults and strategies to mitigate potential harms.
As with prescribing or continuing medications, deprescribing brings with it the potential for harm as well as benefit. Uncertainty and avoidance of harm has been reported as a barrier to deprescribing in practice and may contribute to continuation of inappropriate medications. ⋯ More research is needed into the safety concerns of deprescribing, however, avenues exist during drug development and post-marketing surveillance to gain knowledge on this topic. Questions remain about when it is suitable to discontinue certain medications/medication classes and there is uncertainty about the harms and benefits of both medication continuation and discontinuation in complex older adults.
