In 2011, the FDA asked the manufacturers of the selective serotonin reuptake inhibitor (SSRI) citalopram (Celexa, and generics) to lower the maximum daily dosage of the drug because of a dose-related increase in the QT interval. Since then, some of our readers have asked whether escitalopram (Lexapro, and generics), the active enantiomer of citalopram, could have the same effect.

Ocriplasmin (Jetrea – ThromboGenics) was recently approved by the FDA as an intravitreal injection for treatment of symptomatic vitreomacular adhesion. It is the first drug to be approved in the US for this indication.

Electronic cigarettes, also called e-cigarettes, are advertised as a safer, more convenient, and socially acceptable alternative to smoking tobacco cigarettes. Widely available in retail stores and on the Internet, their use has been increasing over recent years, primarily among smokers, but also among non-smokers.

Pancreatic enzyme replacement products have been used for years to improve digestion in patients with exocrine pancreatic insufficiency (EPI). These products were initially marketed before formal FDA approval was required; in 1991, however, the FDA told all manufacturers of pancreatic enzyme replacement products that they would have to submit a new drug application by April 2010 in order to keep their products on the market.EPI is a chronic disorder characterized by a deficiency of exocrine pancreatic enzymes, which results in malabsorption, steatorrhea, and weight loss. Irreversible EPI is...

The FDA has approved vancomycin oral solution (Firvanq – Cutis Pharma) for treatment of Clostridium difficile-associated diarrhea and enterocolitis caused by Staphylococcus aureus, including methicillin-resistant strains (MRSA).

The FDA has granted regular approval to the oral kinase inhibitor capmatinib (Tabrecta – Novartis) for treatment of metastatic non-small cell lung cancer (NSCLC) in adults whose tumors have a mutation that leads to mesenchymal-epithelial transition (MET) exon 14 skipping. MET exon 14 skipping mutations occur in 3-4% of NSCLC cases. The drug received accelerated approval for the same indication in 2020 based on initial overall response rates and duration of response.

The copper T 380A (ParaGard - GynoPharma), a new intrauterine contraceptive device (IUD) soon to be marketed in the USA, will be one of only two IUDs available in this country. Progestasert (Alza), which gradually releases progesterone (Medical Letter, 18:65, 1976), is the other.

Pneumocystis carinii pneumonia (PCP) occurs in nearly 80% of patients with the acquired immune deficiency syndrome (AIDS) and is a common cause of morbidity and mortality. Oral trimethoprim-sulfamethoxazole (Bactrim; and others), intravenous isethionate (Pentam 300) and other systemic drugs have been used to prevent PCP, but in AIDS patients, all of these agents can occasionally cause severe adverse effects (Medical Letter, 30:94, 1988). Recently, the US Food and Drug Administration approved marketing of aerosolized pentamidine isethionate (NebuPent - LyphoMed) for this indication. Another...

Clozapine (Clozaril - Sandoz), a dibenzodiazepine antipsychotic drug that has been available in Europe for many years, was recently approved for marketing by the US Food and Drug Administration.
