The FDA has approved oritavancin (Orbactiv – The Medicines Company), a long-acting lipoglycopeptide antibiotic given as a single intravenous (IV) dose, for treatment of acute bacterial skin and skin structure infections caused by susceptible gram-positive bacteria in adults. It is the third lipoglycopeptide antibiotic to be marketed in the US; telavancin (Vibativ) and dalbavancin (Dalvance) were approved earlier.

The FDA has approved the 5-HT4 receptor agonist prucalopride (Motegrity – Shire) for treatment of chronic idiopathic constipation (CIC) in adults. Prucalopride is the only drug currently approved in the US for treatment of CIC that stimulates colonic peristalsis. It has been available in Europe and Canada for several years.

Atogepant (Qulipta – Abbvie), an oral small-molecule calcitonin gene-related peptide (CGRP) receptor antagonist ("gepant"), has been approved by the FDA for prevention of episodic migraine in adults. It is the second oral CGRP receptor antagonist to be approved in the US for this indication; the first was rimegepant (Nurtec ODT), which is also approved for acute treatment of migraine. Parenteral CGRP monoclonal antibodies are approved for prevention of migraine (see Table 3).

Faricimab-svoa (Vabysmo – Genentech), an inhibitor of both vascular endothelial growth factor (VEGF) and angiopoietin-2 (Ang-2), has been approved by the FDA for intravitreal treatment of neovascular (wet) age-related macular degeneration (nAMD) and diabetic macular edema (DME). It is the first drug to become available in the US that targets two pathways involved in maintaining vascular homeostasis. Several VEGF inhibitors are available for treatment of nAMD and DME (see Table 2).

A 0.75% vaginal gel formulation of metronidazole (MetroGel-Vaginal - Curatek) and a 2% vaginal cream formulation of clindamycin phosphate (Cleocin - Upjohn) were recently approved by the US Food and Drug Administration for treatment of bacterial vaginosis. Seven days' treatment with oral metronidazole, 500 mg b.i.d., has been the usual treatment for this condition, with oral clindamycin, 300 mg b.i.d., as an alternative (JL Thomason et al, Am J Obstet Gynecol, 165:1210, 1991).

Dolasetron (Anzemet - Hoechst Marion Roussel), a selective serotonin (5-HT3) receptor antagonist similar to ondansetron (Zofran) and granisetron (Kytril - Medical Letter, 36:61, 1994) is now available for both oral and intravenous use in prevention of nausea and vomiting due to cancer chemotherapy. A 5-HT3 antagonist plus dexamethasone (Decadron, and others) is the most effective regimen for prevention of acute vomiting caused by cancer chemotherapy. Dolasetron has also been approved by the FDA for prevention and treatment of postoperative nausea and...

Adjuvant hormone therapy with anti-estrogen drugs has been shown to reduce disease recurrence and mortality in postmenopausal women with estrogen receptor (ER)-positive breast cancer. In recent years, aromatase inhibitors (AI) have become the preferred first-line hormonal treatment over tamoxifen for such patients.1,2

A recent article in JAMA and an interview of its senior author on 60 Minutes have heightened interest in off-label use of the oral selective serotonin reuptake inhibitor (SSRI) fluvoxamine (Luvox, and generics) to treat COVID-19.
