The FDA has approved Sinuva (Intersect ENT), a sinus implant that gradually releases the corticosteroid mometasone furoate over a 90-day period, for treatment of nasal polyps in adults who have had ethmoid sinus surgery. Propel, a sinus implant that releases mometasone furoate over 30 days, is FDA-approved to maintain the sinus opening after ethmoid sinus surgery; it is marketed by the same manufacturer as Sinuva.

The FDA has approved obiltoxaximab (Anthim – Elusys Therapeutics), a toxin-targeting monoclonal antibody, for treatment of inhalational anthrax in combination with antibacterial drugs and prophylaxis of inhalational anthrax when other therapies are unavailable or inappropriate. Raxibacumab, another monoclonal antibody, was approved earlier for the same indication. Like raxibacumab, obiltoxaximab is being manufactured only for the CDC national stockpile and is not available for commercial sale.

The FDA has approved an extended-release tablet formulation of amantadine (Osmolex ER – Vertical/Osmotica) for once-daily treatment of Parkinson's disease (PD) and drug-induced extrapyramidal symptoms (EPS) in adults. An extended-release capsule formulation of amantadine (Gocovri) was approved in 2017 for treatment of levodopa-induced dyskinesia in patients with PD.

The FDA has approved lutetium Lu 177 dotatate (Lutathera – Advanced Accelerator Applications), a radiolabeled somatostatin analog, for treatment of somatostatin receptor-positive gastroenteropancreatic neuroendocrine tumors (GEPNETs) in adults.

Pharmacologic management of opioid withdrawal symptoms can reduce the intensity of drug craving and improve treatment retention in patients with opioid use disorder who will receive maintenance treatment. Withdrawal management without subsequent maintenance treatment is associated with high rates of relapse, overdose death, and HIV and/or hepatitis C virus infection. Several guidelines on management of opioid withdrawal are available. Maintenance treatment of opioid use disorder was reviewed in a previous issue.

The FDA has approved a single-injection hyaluronic acid gel (Durolane – Bioventus) and an extended-release (ER) formulation of the synthetic corticosteroid triamcinolone acetonide (Zilretta – Flexion) for intra-articular (IA) treatment of osteoarthritic knee pain.

The FDA has required changes in the labeling of all systemic fluoroquinolone antibiotics to strengthen warnings about the risk of severe hypoglycemia and mental health effects associated with their use.1An FDA review identified 67 cases of hypoglycemic coma associated with fluoroquinolone use, 22 of which resulted in death or disability. Most cases occurred in patients with risk factors such as diabetes (especially those taking a sulfonylurea), older age, or renal insufficiency.1 In observational studies in older adults and patients with diabetes, fluoroquinolones have been associated with...

The FDA has approved Biktarvy (Gilead), a once-daily, fixed-dose combination of bictegravir, a new integrase strand transfer inhibitor (INSTI), and the nucleoside reverse transcriptase inhibitors (NRTIs) emtricitabine and tenofovir alafenamide (TAF), for treatment of HIV-1 infection in adults. The new combination is indicated for use in patients who are antiretroviral-naive or who have been virologically suppressed on a stable antiretroviral regimen for ≥3 months with no history of treatment failure and no known substitutions associated with resistance to any component of the...

The FDA has approved a 6% otic suspension formulation of the fluoroquinolone antibiotic ciprofloxacin (Otiprio – Otonomy) for single-dose treatment of acute otitis externa (swimmer's ear) caused by Pseudomonas aeruginosa or Staphylococcus aureus in patients ≥6 months old. Otiprio was approved earlier for prophylaxis in children with bilateral otitis media with effusion who are undergoing tympanostomy tube placement.
