The FDA has expanded its Emergency Use Authorizations (EUAs) for the COVID-19 vaccines manufactured by Pfizer/BioNTech (Comirnaty) and Moderna (Spikevax) to permit use of the bivalent formulations of these products (containing mRNA from the original and BA.4/5 Omicron strains of SARS-CoV-2) as a booster dose in children as young as 5 years old (Pfizer) or 6 years old (Moderna). The bivalent Pfizer vaccine had previously been authorized for use in persons ≥12 years old and the bivalent Moderna vaccine in persons ≥18 years old. Bivalent vaccines are not authorized for...

Topical minoxidil (Rogaine, and others), which is available over the counter, has been used for treatment of hair loss in men and women for more than 30 years. Recently published trials suggest that off-label use of a low dose of oral minoxidil may also be effective.

The FDA has approved mannitol powder for oral inhalation (Bronchitol – Chiesi) as add-on maintenance treatment to improve pulmonary function in adults with cystic fibrosis (CF). This product has been available in Europe for the same indication since 2012. Another formulation of mannitol inhalation powder (Aridol) is approved in the US for assessment of bronchial hyperresponsiveness.

The FDA has approved Lybalvi (Alkermes), a fixed-dose combination of the second-generation antipsychotic olanzapine (Zyprexa, and generics) and samidorphan, a new opioid antagonist, for treatment of adults with schizophrenia or with manic or mixed episodes of bipolar I disorder. The addition of samidorphan is intended to mitigate the weight gain that occurs with olanzapine. This is the first FDA approval for samidorphan.

Three products are currently available in the US for treatment of high-risk,1 nonhospitalized adults with mild to moderate COVID-19: oral ritonavir-boosted nirmatrelvir (Paxlovid), IV remdesivir (Veklury), and oral molnupiravir (Lagevrio). Remdesivir is FDA-approved for such use; nirmatrelvir/ritonavir and molnupiravir are available under an FDA Emergency Use Authorization. Because the pivotal clinical trials of these products for outpatient use were conducted in patients who were not vaccinated against COVID-19, some clinicians have questioned whether they can benefit vaccinated...

Donanemab-azbt (Kisunla – Lilly), an IV amyloid beta-directed monoclonal antibody, has been approved by the FDA for treatment of Alzheimer's disease (AD). The label states that the drug should only be started in patients with mild cognitive impairment (MCI) or mild dementia. Donanemab is the third IV amyloid beta-directed monoclonal antibody to be marketed in the US. Lecanemab (Leqembi – Biogen/Eisai) was approved by the FDA in 2023 for the same indication as donanemab. Aducanumab (Aduhelm – Lilly) was granted accelerated approval in 2021, but it was withdrawn from the market...

Donidalorsen (Dawnzera – Ionis), a subcutaneously injected prekallikrein-directed antisense oligonucleotide, has been approved by the FDA for prevention of hereditary angioedema (HAE) attacks in patients ≥12 years old. It is the first RNA-targeted drug to be approved in the US for this indication.

Yutrepia (Liquidia), a dry powder inhaler formulation of the prostacyclin analog treprostinil, has been approved by the FDA to improve exercise ability in adults with pulmonary arterial hypertension (PAH; WHO Group 1) or pulmonary hypertension associated with interstitial lung disease (PH-ILD; WHO Group 3). Tyvaso DPI, another treprostinil dry powder inhaler, was approved earlier for the same indication.

The FDA now requires that product labels for the long-acting injectable progestin contraceptive medroxyprogesterone acetate (MPA; Depo-Provera CI, and generics; Depo-SubQ Provera 104) include a warning about the risk of meningioma associated with its use.
