Acute heart failure (AHF) is one of the most important causes of mortality, morbidity and rising healthcare costs. Despite this, there has been minimal advancement in the management of AHF and the treatment continues to focus on symptomatic improvement using vasodilators, diuretics and inotropes, none of which have shown any mortality benefits. ⋯ A single intravenous infusion of relaxin over 48 hours has been shown to provide significant dyspnea relief among AHF patients, with an ongoing study to evaluate its potential for mortality benefit. This article provides an insight into the pharmacology of this novel therapy for AHF with an eye towards future clinical applications.

Empagliflozin is an oral sodium-glucose cotransporter 2 (SGLT2) inhibitor that reduces hyperglycemia in type 2 diabetes mellitus (T2DM) by decreasing renal glucose reabsorption and promoting urinary glucose excretion. In clinical trials, empagliflozin demonstrated significant improvements in glycemic control, as monotherapy and in combination regimens. In addition, empagliflozin was associated with weight loss and moderate reductions in blood pressure. ⋯ Across the trials in general, empagliflozin was well tolerated, with no increased risk of hypoglycemia except when used with an insulin secretagogue or insulin. An increased risk of genital infections and urinary tract infections has been reported, although the association is less clear for urinary tract infections. Overall, empagliflozin appears to be a promising treatment for T2DM.

The mile-high city of Denver was the site of this year's World Conference on Lung Cancer, which reached its 16th event. The conference scheduled 3 days of intensive scientific research presentations and discussions arranged in oral, mini-oral and poster sessions, plus an array of additional educational sessions. Being the largest international gathering of lung cancer and thoracic malignancy clinicians and researchers, important new research on prevention, screening and treatment of lung cancer and other malignancies of the thorax, with special emphasis on thymoma and mesothelioma, was presented during the conference.

Treatment of opioid-induced constipation (OIC) is becoming a relevant clinical challenge as most of the treatments demonstrated to be more effective than placebo in treating OIC have safety issues limiting a broad clinical application. Naloxegol is the first orally administered, peripherally acting, µ opioid receptor antagonist approved by the FDA and EMA specifically for the treatment of noncancer patients with OIC. This review summarizes the results of the studies regarding the effects of naloxegol in OIC. ⋯ Side effects were mainly gastrointestinal in origin (and usually transient and mild) and there were no signs of opioid withdrawal in the studies. Safety and tolerability were shown in a long-term safety study. Considering its efficacy, safety, route of administration and the limitations of most of the other available treatments, naloxegol has the potential to become the first-line treatment for noncancer patients with OIC.

Hydrocodone bitartrate is the most commonly used drug for acute and chronic pain in the U. S. with over 135 million prescriptions in 2012. The U. ⋯ The FDA has rescheduled hydrocodone from Schedule III to Schedule II which went into effect on October 6, 2014, along with a limit on added acetaminophen of 325 mg for each dose of hydrocodone. This review examines the evolution of hydrocodone into a common and yet controversial drug in the U. S. with its pharmacokinetics, pharmacodynamics, safety and efficacy.
