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).

The FDA has approved a subcutaneously injected, extended-release formulation of the mu-opioid receptor partial agonist and kappa-opioid receptor antagonist buprenorphine (Brixadi – Braeburn) for once-weekly or once-monthly treatment of moderate to severe opioid use disorder. Brixadi is the second subcutaneously injected buprenorphine formulation to be approved in the US; Sublocade, which is administered once monthly, was the first. Buprenorphine is also available for treatment of opioid use disorder in sublingual formulations with and without the opioid antagonist...

Betaxolol (Kerlone - Searle), an oral beta-adrenergic blocker, was recently approved by the US Food and Drug Administration for once-daily treatment of hypertension. The new drug is beta 1 (cardio)-selective with no intrinsic sympathomimetic (partial agonist) activity. It is also available in a topical formulation for treatment of glaucoma (Betoptic - Medical Letter, 28:45, 1986).

The FDA has approved ingenol mebutate (Picato – Leo) for topical treatment of actinic keratoses (AKs). The new drug is derived from the sap of the Euphorbia peplus plant, a traditional folk remedy for warts and other skin lesions.

Tofersen (Qalsody – Biogen), an intrathecally administered antisense oligonucleotide, has received accelerated approval from the FDA for treatment of amyotrophic lateral sclerosis (ALS) in adults who have a mutation in the superoxide dismutase 1 (SOD1) gene. About 2% of patients with ALS have mutations in the SOD1 gene. Tofersen is the first drug to be approved in the US that targets a genetic cause of ALS. Accelerated approval of the drug was based on the surrogate endpoint of a reduction in plasma neurofilament light chain, which is considered likely to predict clinical...

Grepafloxacin (Raxar - Glaxo Wellcome), a once-daily oral fluoroquinolone, is now being marketed for treatment of community-acquired pneumonia, acute bacterial exacerbations of chronic bronchitis, uncomplicated gonorrhea, and nongonococcal urethritis and cervicitis.

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).

The FDA has approved the use of ulipristal acetate (ella – Watson) as an emergency contraceptive that can be taken up to 5 days after unprotected intercourse. It is available only by prescription.
