SGLT2 inhibitors for heart failure with reduced ejection fraction: a real EMPEROR?
Introduction: In individuals with type 2 diabetes mellitus, sodium-glucose cotransporter 2 (SGLT2) inhibitors reduce the risk of hospitalization for heart failure and serious adverse renal events, both in randomized controlled trials and observational studies. Areas covered: In this paper, the authors critically discuss the rationale, results, and implications of the recent placebo-controlled EMPEROR-Reduced trial [NCT03057977], which evaluated empagliflozin in subjects with chronic heart failure and a reduced ejection fraction (HFrEF), with or without diabetes. ⋯ Expert opinion: EMPEROR-Reduced confirmed and extended the findings from DAPA-HF, especially on renal outcomes, thus strengthening the rationale for considering SGLT2 inhibitors among established treatments in HFrEF. Forthcoming guidelines supported by the knowledge of the clinical pharmacology of SGLT2 inhibitors will hopefully assist cardiologists, nephrologists, and general practitioners in selecting the target population and promoting safe prescribing.

ReviewPharmacological strategies to treat attacks of episodic migraine in adults.
Migraine patients prioritize early complete relief of headache and associated symptoms, sustained freedom of pain, and good tolerability. One major obstacle for the successful use of drug treatment of migraine attack is that the speed of action of triptans, 5-HT1B/1D receptor agonists, is delayed. ⋯ The delay in the onset of effect of acute migraine drugs is likely due to a complex antimigraine system involving more than one site of action. Investigations into the mechanisms of the delay should have a high priority, both in studies with animals, migraine models, and in migraine patients during attacks. Non-oral administration of antimigraine drugs resulting in early absorption of drugs should be developed as they possibly also can increase Emax.

Evaluation of cardiovascular and renal outcomes with ertugliflozin: what is the VERdict from the VERTIS-CV trial?
A growing number of antidiabetic agents have demonstrated cardiovascular and renal benefits in cardiovascular outcome trials (CVOTs), despite such trials being principally required to rule out excess cardiovascular risk. ⋯ In patients with type 2 diabetes and ASCVD, ertugliflozin appears safe with a noted non-significant trend toward improved renal outcomes. Approximately 23.7% of patients in the VERTIS-CV trial had heart failure, the highest among SGLT-2 inhibitor CVOTs. The VERTIS-CV trial reaffirms the reduction in heart failure hospitalizations as a likely class effect of SGLT-2 inhibitors. While the trial supports the use of ertugliflozin beyond glycemic control, agents with confirmed superiority for improved cardiovascular outcomes and mortality may be preferred.

ReviewAn evaluation of sodium zirconium cyclosilicate as a treatment option for hyperkalemia.
Hyperkalemia, defined as serum potassium level > 5.0 mEq/l, is associated with serious cardiac dysrhythmias, sudden death and increased mortality risk. It is common in patients with chronic kidney disease (CKD), diabetes (DM) and heart failure (HF), particularly in those treated with the renin-angiotensin-aldosterone system (RAAS) inhibitors or potassium-sparing diuretics. Although these drugs have documented renal and cardiac protective benefits, frequent hyperkalemia associated with their use often dictates administration of suboptimal doses or their discontinuation altogether. Treatment for chronic hyperkalemia in these settings has been challenging; however, the recent introduction of two new potassium-binding resins has revolutionized our approach to treating hyperkalemia. ⋯ SZC and Patiromer are promising new agents for lowering serum potassium in hyperkalemic patients, including those with CKD, with and without DM or HF, facilitating the use of the RAAS inhibitors for renal and cardiac protection. Recent randomized clinical trials have shown that SZC effectively lowers serum potassium and maintains normokalemia in most hyperkalemic patients. Clinical trials showed that SZC lowers serum potassium within 1 h, although it is not approved for treating acute hyperkalemia. SZC was well tolerated and associated with minimal adverse effects.

Uterine fibroids (UF) are benign tumors common in premenopausal women, with strong impact on the health-care systems. For many years, surgery represented the only therapy for symptomatic fibroids. However, clinicians are observing a switch from surgery to noninvasive methods; in particular, medical treatment has been shown to be efficacious in obtaining a bleeding reduction and in ameliorating patient conditions. ⋯ Relugolix is a promising drug for the non-surgical treatment of women with UF. To date, the only published data come from a well-selected Japanese female population study while results from worldwide ongoing studies are ongoing in order to confirm the efficacy of this GnRH agonist receptor.
