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.

Policies to mitigate nonmedical use of prescription medications: how should emerging evidence of gabapentin misuse be addressed?
Over the past decade, increased prescription supply has facilitated an epidemic of nonmedical use of controlled substances, including predominantly opioids, as well as benzodiazepines, z-hypnotics, and stimulants. Areas covered: More recently, misuse of noncontrolled prescriptions, such as gabapentin, has been detected. Gabapentin misuse has been associated with drug-related harm and increased healthcare service utilization in a few studies, including a recent large-sample analysis of commercially insured enrollees in the United States (U. ⋯ S. states have acted to prevent or detect gabapentin misuse by requiring the inclusion of gabapentin utilization in reporting to local Prescription Drug Monitoring Programs (PDMPs) and/or imposing other restrictions on gabapentin prescribing (e.g., classification as a controlled substance, quantity limits). These efforts may result in unintentional harm by (1) encouraging 'doctor shopping' across state lines to seek lenient regulatory policies and (2) placing the burden for mitigating misuse on individual practitioners. Expert opinion: We call for a unified national approach, comprising federal regulation and enhanced PDMP reporting to address gabapentin misuse, while laying the groundwork for management of new medications of abuse that the healthcare industry may encounter in the future.

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.
