The FDA has approved daclatasvir (Daklinza – BMS), an oral direct-acting antiviral drug, for use with sofosbuvir (Sovaldi) for treatment of chronic hepatitis C virus (HCV) genotype 3 infection. Daclatasvir is the first drug approved for this indication that does not require the addition of interferon or ribavirin. It is approved in Japan and Europe in combination with other drugs for treatment of HCV genotypes 1-4.

The FDA has approved eluxadoline (Viberzi – Actavis), a mu-opioid receptor agonist and delta-opioid receptor antagonist, for oral treatment of adults with irritable bowel syndrome with diarrhea (IBS-D).

Resmetirom (Rezdiffra – Madrigal), a thyroid hormone receptor-beta agonist, has received accelerated approval from the FDA for treatment of noncirrhotic nonalcoholic steatohepatitis (NASH) with moderate to advanced fibrosis in adults. NASH has recently been renamed metabolic dysfunction-associated steatohepatitis (MASH). Resmetirom is the first drug to be approved in the US for this indication.

The FDA has approved darolutamide (Nubeqa – Bayer), an androgen receptor inhibitor, for oral treatment of nonmetastatic castration-resistant prostate cancer (nmCRPC). Darolutamide is the third androgen receptor inhibitor to be approved for this indication; apalutamide (Erleada) and enzalutamide (Xtandi), which are also approved for use in patients with metastatic castration-resistant prostate cancer (mCRPC), were approved earlier.

The FDA has approved Mavyret (Abbvie) and Vosevi (Gilead), two new fixed-dose combinations of direct-acting antiviral (DAA) drugs, for treatment of chronic hepatitis C virus (HCV) infection caused by any of the six major HCV genotypes in patients without cirrhosis or with compensated cirrhosis. Both are approved for use in treatment-experienced patients. Mavyret is also approved for treatment-naive patients.

Per capita spending on prescription drugs in the US is higher than in other industrialized nations, including Canada.

Annovera (TherapeuticsMD), a contraceptive vaginal ring that releases segesterone acetate, a synthetic progestin, and ethinyl estradiol, was approved by the FDA in 2018 and is now available. It is the first product to contain segesterone and the second vaginal ring to become available in the US; NuvaRing, which delivers etonogestrel and ethinyl estradiol, was the first. Unlike NuvaRing, which requires use of a new ring each month, the Annovera ring can be used for an entire year, but it must be removed for one week each month.

The FDA has approved the monoamine oxidase type B (MAO-B) inhibitor safinamide (Xadago – US Worldmeds) as an adjunct to levodopa/carbidopa for management of "off" episodes in patients with Parkinson’s disease (PD). It is the first reversible MAO-B inhibitor to be approved for this indication. Selegiline (Eldepryl, and others) and rasagiline (Azilect, and generics), two irreversible MAO-B inhibitors, have been used alone and as adjuncts to levodopa/carbidopa for many years. Safinamide is not approved for use as monotherapy.

The FDA has approved inclisiran (Leqvio – Novartis), a small interfering RNA (siRNA) directed to proprotein convertase subtilisin/kexin type 9 (PCSK9) mRNA, as an adjunct to diet and maximally tolerated statin therapy for subcutaneous (SC) treatment of adults with heterozygous familial hypercholesterolemia (HeFH) or clinical atherosclerotic cardiovascular disease (ASCVD) who require additional lowering of low-density lipoprotein cholesterol (LDL-C). Inclisiran is the first FDA-approved PCSK9-directed siRNA therapeutic agent.
