Review of clinical data on andexanet alfa for the reversal of factor Xa (FXa) inhibitor associated anticoagulation. ⋯ Studies evaluating laboratory parameters for coagulation show that andexanet alfa rapidly neutralizes the anticoagulant effects of apixaban, enoxaparin, edoxaban, and rivaroxaban. Clinical studies show that andexanet alfa improves markers related to coagulation, and reverses major bleeding in healthy volunteers and patients with life-threatening bleeding. Interruption of anticoagulation may result in thromboembolic and ischemic events. The use of andexanet alfa requires close monitoring for signs and symptoms of thromboembolic events, ischemic events, and cardiac arrest. Furthermore, anticoagulation should be resumed following the administration of andexanet alfa as soon as medically appropriate.

Atypical antipsychotics (AAP) have been associated with reduced duration of delirium in the intensive care setting. However, long-term use of these drugs is associated with significant adverse events, including increased all-cause mortality in the elderly. Inappropriate continuation of AAPs after discharge from the intensive care unit (ICU) is worrisome and needs to be addressed.The aim of this work was to assess the prevalence of continuation of AAPs after hospital discharge and evaluate the associated risk factors. ⋯ Male sex and discharge to a healthcare facility were associated with a higher rate of continuation. Research into practical methods to reduce their continuation upon discharge should be performed to mitigate the long-term risks of AAP administration.

Patients from residential aged care facilities are commonly exposed to inappropriate polypharmacy. Unplanned inpatient admissions can provide an opportunity for review of complex medical regimens and deprescribing of inappropriate or nonbeneficial medications. The aim of this study was to assess the efficacy, safety and sustainability of in-hospital deprescribing. ⋯ Deprescribing medications during an unplanned hospital admission was not associated with mortality, readmissions, or overall HRQOL.

Sugammadex is used for the reversal of neuromuscular blockade caused by rocuronium bromide and vecuronium bromide. As part of the post licensing phase of drug development, adverse events related to the use of sugammadex are still being uncovered and being reported. The potential association between sugammadex and adverse events bronchospasm and coronary arteriospasm using a retrospective pharmacovigilance signal analysis was carried out. ⋯ The results of the pharmacovigilance analysis highlight a statistically significant disproportionality signal between sugammadex usage and bronchospasm and coronary arteriospasm adverse events. Physicians need to be aware of these adverse events when using sugammadex.

Hyperkalemia is an electrolyte abnormality that may cause ventricular dysrhythmias and cardiac arrest. The presence of hyperkalemia may necessitate prompt treatment via intravenous insulin and dextrose. One notable complication of this therapy is the development of hypoglycemia. Previous trials have examined the impact of altering the insulin dose administered on hypoglycemia development; no trials to date however, have examined the impact of altering the dextrose dose. ⋯ In the overall patient population, use of 50 g of dextrose instead of 25 g does not reduce hypoglycemia incidence. However, it may be beneficial is select patient populations, such as patients without type 2 diabetes or patients with a baseline blood glucose <110 mg/dl. Administration of 50 g of dextrose did not appear to place patients at significant risk for hyperglycemia however and could be considered during treatment of hyperkalemia.
