New guidelines from The National Cholesterol Education Program recommend, as a therapeutic option, lowering treatment goals for LDL cholesterol (LDL-C) from <100 mg/dL to <70 mg/dL for patients at very high risk for coronary heart disease and from 130 mg/dL to <100 mg/dL for those at moderately high risk. A likely consequence of these recommendations is increased use of statins and use of higher doses with a concomitant increase in adverse effects.

The FDA has approved the fully-human programmed death ligand 1 (PD-L1) blocking antibody avelumab (Bavencio – EMD Serono/Pfizer) for treatment of metastatic Merkel cell carcinoma (MCC) in patients ≥12 years old. Avelumab is the first drug to be approved in the US for this rare skin cancer. About 1600 people in the US, most commonly older adults (mean age at presentation is 75 years), are diagnosed each year with MCC. Most of these patients can be treated with surgical resection, but ~50% will have a recurrence and >30% will eventually have metastatic disease. Median progression-free...

The FDA has removed a boxed warning from the labeling of products containing the sodium-glucose co-transporter 2 (SGLT2) inhibitor canagliflozin (Invokana, Invokamet, Invokamet XR) that described an increased risk of lower limb amputation associated with use of the drug. Package inserts for canagliflozin products still contain a standard warning about a risk of lower limb amputation.

Age-related macular degeneration (AMD) has two major forms: dry or non-neovascular (~90% of patients) and wet or neovascular (~10% of patients).

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

With increasing travel, immigration, use of immunosuppressive drugs and the spread of AIDS, physicians anywhere may see infections caused by parasites. The table in this document lists first-choice and alternative drugs for most parasitic infections.

Dronedarone (Multaq – Sanofi), an analog of amiodarone, was approved by the FDA in 2009 for oral treatment of paroxysmal or persistent (non-permanent) atrial fibrillation or atrial flutter. Amiodarone (Cordarone, and others) is more effective for this indication, but its use is often limited by its adverse effects, including thyroid and pulmonary toxicity.

The oral biguanide metformin (Glucophage, and others) is generally the drug of choice for initial treatment of type 2 diabetes. It has also been used to prevent or at least delay the onset of diabetes in patients considered to be at high risk for the disease. Recent guidelines recommend considering use of metformin in patients with prediabetes (fasting plasma glucose 100-125 mg/dL, 2-hr post-load glucose 140-199 mg/dL, or A1C 5.7-6.4%), especially in those who are <60 years old, have a BMI >35 kg/m2, or have a history of gestational diabetes. Metformin has not been approved...

The FDA has expanded its Emergency Use Authorization for the adjuvanted protein subunit COVID-19 vaccine manufactured by Novavax to include use of the vaccine as a two-dose primary series in adolescents 12-17 years old. The vaccine was authorized for primary immunization of adults in July 2022.

The FDA has approved Furoscix (scPharmaceuticals), a subcutaneous formulation of the loop diuretic furosemide administered via a single-use, on-body infusor, for treatment of congestion due to fluid overload in adults with New York Heart Association (NYHA) Class II-III chronic heart failure (HF). Furosemide (Lasix, and generics) has been available for years in oral and IV formulations.
