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.

Review Meta AnalysisThe tolerability and safety profile of patiromer: a novel polymer-based potassium binder for the treatment of hyperkalemia.
Hyperkalemia (HK) occurs often among patients with chronic kidney disease (CKD) and heart failure (HF) and those treated with renin-angiotensin-aldosterone system inhibitors (RAASI). Even small deviations from normal potassium levels carry increased risk of mortality. Patiromer is approved for treatment of HK and has been shown in clinical trials to reduce serum potassium among patients with HK and comorbid conditions. ⋯ Patiromer effectively reduces serum potassium, and gastrointestinal adverse events (AEs) are the most common patiromer-associated AEs. Effective management of HK with patiromer may allow use of RAASI at optimal doses as recommended by treatment guidelines. Future research should examine the potential for potassium binders, including patiromer, to extend use of RAASI in appropriate patient populations.

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.

ReviewRecommendations on managing lenvatinib and everolimus in patients with advanced or metastatic renal cell carcinoma.
There are several second-line treatment options for patients with renal cell carcinoma after first-line failure of a tyrosine kinase inhibitor, especially with the recent approvals of cabozantinib, nivolumab, and the lenvatinib plus everolimus combination. A lack of reliable biomarkers and an overall lack of prospective head-to-head comparisons make it a challenge to choose a second-line treatment in the clinic. ⋯ At the same time, the safety profile of this combination, including the rate of total and severe adverse events, the percentage of dose reductions required, and the rate of treatment discontinuation, was less favorable compared with available monotherapy options, suggesting that better management could help to maximize the activity of this combination while protecting patients from undue harm. Expert opinion: Herein, we aim to postulate multidisciplinary recommendations on the advice to offer to patients and caregivers before starting treatment and how to manage the combination from the perspective of daily clinical practice.
