The cardiovascular safety of the thiazolidinedione rosiglitazone (Avandia – GlaxoSmithKline) is in the news again, with some authorities calling for its removal from the market (New York Times, February 19, 2010).

Resveratrol is a phytochemical found in the skin of red grapes and in many other plants, including berries, plums and peanuts. As a constituent of red wine, it has been associated with cardioprotective effects. Dietary supplements containing resveratrol are now being widely promoted as antioxidants that can prevent agerelated diseases.

In recently published clinical trials, once-weekly subcutaneous injection of the glucagon-like peptide 1 (GLP-1) receptor agonist semaglutide (Ozempic – Novo Nordisk), which is FDA-approved for treatment of type 2 diabetes and to reduce the risk of major adverse cardiovascular events in adults with type 2 diabetes and established cardiovascular disease, has reduced body weight significantly in patients with and without type 2 diabetes when given in addition to lifestyle intervention. Liraglutide (Saxenda), another GLP-1 receptor agonist, has been FDA-approved for chronic weight...

The injectable glucagon-like peptide-1 (GLP-1) receptor agonist semaglutide (Wegovy) has received accelerated approval from the FDA for treatment of noncirrhotic metabolic dysfunction-associated steatohepatitis (MASH; previously known as nonalcoholic steatohepatitis [NASH]) with moderate to advanced liver fibrosis in adults. It is the second drug and the first GLP-1 receptor agonist to be approved in the US for treatment of MASH; resmetirom (Rezdiffra), a thyroid hormone receptor-beta agonist, was granted accelerated approval for the same indication in 2024.

Infertility occurs in about 15% of couples. About one-third of cases are due to problems with ovulation or other female factors, another third are due to a male infertility factor, and the remaining third are unexplained. In older women, unexplained infertility is probably caused by diminished quality and quantity of oocytes. The first approach to treatment of female-factor infertility generally is the use of drugs that stimulate oocyte production.

The FDA has approved sodium zirconium cyclosilicate (Lokelma – AstraZeneca), an oral potassium binder that exchanges hydrogen and sodium for potassium in the gastrointestinal (GI) lumen, for treatment of non-life-threatening hyperkalemia in adults. Sodium zirconium cyclosilicate (SZC) is the third drug to be approved for this indication; sodium polystyrene sulfonate and patiromer (Veltassa) were approved earlier.

The FDA has approved a fixed-dose combination of the opioid receptor antagonist naltrexone (ReVia, and others) and the antidepressant and smoking cessation agent bupropion (Wellbutrin SR, Zyban, and others), as Contrave (Orexigen/Takeda) for weight loss. The combination was approved for use as an adjunct to diet and increased physical activity in patients with a body mass index (BMI) ≥30 kg/m2 or a BMI ≥27 kg/m2 and one or more weight-related comorbidities such as hypertension, diabetes, or dyslipidemia. Naltrexone/bupropion is not a controlled...

Atazanavir (Reyataz - Bristol-Myers Squibb), a new protease inhibitor (PI), and emtricitabine (Emtriva - Gilead), a nucleoside analogue reverse transcriptase inhibitor (NRTI) chemically similar to lamivudine, have been approved by the FDA for treatment of HIV-1 infection. Both are taken once daily, unlike most anti-HIV drugs.

Every pharmaceutical drug is a dose-dependent poison. This article describes the clinical presentation and treatment of some dangerous overdoses commonly reported in adults.

Coenzyme Q10, a fat-soluble antioxidant also known as ubidecarenone, ubiquinone and CoQ10, is marketed as a dietary supplement in the US, both as a single ingredient and in various combination products.
