The FDA recently approved the monoamine oxidase inhibitor (MAOI) selegiline in a transdermal (patch) formulation (Emsam - Bristol-Myers Squibb/Somerset) for treatment of major depressive disorder. Selegiline is also available in an oral formulation (Eldepryl, and others) for treatment of Parkinson's disease.

An injectable extended-release formulation of the opioid-receptor antagonist naltrexone (Vivitrol - Alkermes/Cephalon) has been approved by the FDA for once-monthly use, along with psychosocial support, to maintain abstinence from alcohol. Naltrexone inhibits the rewarding effects of alcohol. Oral naltrexone (Revia, and others) has been approved for treatment of alcohol dependence since 1994, but poor adherence has limited its effectiveness. In the new extended-release (XR) formulation, naltrexone is encapsulated in polylactide-co-glycolide microspheres (similar to absorbable suture material)...

The FDA has approved ivabradine (Corlanor – Amgen) to reduce the risk of hospitalization for worsening heart failure in adults with stable, symptomatic chronic heart failure with left ventricular ejection fraction (LVEF) ≤35% who are in sinus rhythm with a resting heart rate ≥70 beats per minute and who are on maximum tolerated doses of beta blockers or have a contraindication to beta blocker use. Ivabradine has been available internationally for years as Procoralan and Corlentor for treatment of stable angina and heart failure.

Methadone, an opioid agonist that can be taken orally, has been used for maintenance treatment for many years in the USA (DM Novick et al, Drug Alcohol Depend, 33:235, 1993). Last year, the US Food and Drug Administration approved the distribution and use of L-alpha-acetyl-methadol (LAAM; ORLAAM - Bio Development Corporation, McLean, VA), a long-acting congener of methadone. LAAM, like methadone, will be available for this indication only through federal and state-regulated treatment programs.

Ketoconazole (Nizoral - Janssen), an imidazole antifungal drug widely used in a tablet formulation for treatment of systemic fungal infections (Medical Letter 36:16, 1994) and as a topical preparation for fungal skin infections, is also available as a shampoo for treatment of seborrheic dandruff. The shampoo is sold only by prescription.

The FDA has approved ipilimumab (Yervoy – Bristol-Myers Squibb), a recombinant human monoclonal antibody, for treatment of unresectable or metastatic melanoma.

The FDA has approved Yosprala (Aralez), a fixed-dose combination of delayed-release aspirin and immediate-release omeprazole, for secondary prevention of cardiovascular and cerebrovascular events in patients who are at risk of developing aspirin-associated gastric ulcers (≥55 years old or history of gastric ulcers). Yosprala is the first product to become available in the US that combines aspirin and a proton pump inhibitor (PPI).

The oral kinase inhibitor pemigatinib (Pemazyre – Incyte) has been approved by the FDA for treatment of adults with relapsed or refractory myeloid/lymphoid neoplasms (MLNs) with fibroblast growth factor receptor 1 (FGFR1) rearrangements. It is the first targeted therapy to be approved in the US for this indication. The drug received accelerated approval from the FDA in 2020 for treatment of adults with previously treated, unresectable, locally advanced or metastatic cholangiocarcinoma with FGFR2 fusions or other rearrangements.

As cocaine continues to be widely available in the USA (Medical Letter, 28:69, 1986), new problems associated with its use continue to emerge. Some recent reports indicate that use of the drug during pregnancy can damage the fetus, lead to abortion or premature labor, and cause toxic effects in the newborn infant.

Ibutilide fumarate (Corvert - Pharmacia & Upjohn), a new antiarrhythmic drug for intravenous use, has been approved by the US Food and Drug Administration for acute termination of atrial fibrillation or flutter of recent onset.
