The FDA has approved the interleukin (IL)-6 inhibitor sarilumab (Kevzara – Sanofi/Regeneron) for treatment of polymyalgia rheumatica (PMR) in adults who had an inadequate response to corticosteroids or cannot tolerate a corticosteroid taper. Sarilumab is the first biologic drug to be approved for treatment of PMR; it was previously approved for treatment of rheumatoid arthritis.

The FDA has approved Menveo (Novartis), a new quadrivalent conjugated polysaccharide vaccine, for protection against disease caused by Neisseria meningitidis in people 11-55 years old.

The FDA has approved the subcutaneously injected interleukin (IL)-4 receptor alpha antagonist dupilumab (Dupixent – Sanofi/Regeneron) for treatment of eosinophilic esophagitis (EoE) in patients ≥12 years old who weigh ≥40 kg and treatment of prurigo nodularis in adults. Dupilumab is the first drug to be approved in the US for each of these indications. It is also FDA-approved for treatment of atopic dermatitis, asthma, and chronic rhinosinusitis with nasal polyposis.

Treatment of community-acquired pneumonia (CAP) is usually empiric, with selected antibiotic regimens directed against some of the most common causative pathogens. Recommended empiric regimens are listed in Table 2; recommended antibiotic dosages for treatment of CAP are listed in Tables 3 and 4. Joint guidelines for treatment of CAP by the American Thoracic Society and the Infectious Diseases Society of America (ATS/IDSA) were updated in 2019.

Acute cough (<3 weeks in duration) generally does not require pharmacologic treatment, especially in children. Suppression of productive cough may be harmful. Management of patients with cough should include elimination of any precipitating factor (e.g., cigarette smoking) and treatment of any underlying cause such as upper airway cough syndrome, gastroesophageal reflux disease, asthma, or other pulmonary disease.

immune globulin (human) has been available for many years in an intramuscular (IM) formulation for prevention of Rh isoimmunization in pregnant Rh-negative women (Medical Letter, 16:3, 1974). Recently, the US Food and Drug Administration (FDA) approved the first intravenous (IV) immune globulin preparation (WinRho SD - Univax), not only for preventing Rh isoimmunization, but also for treatment of immune thrombocytopenic purpura (ITP) in Rh-positive patients.

A vaccine to prevent both Hepatitis A and Hepatitis B (Twinrix), previously licensed in Canada and Europe, is now available in the US for adults.

The FDA has approved Glyxambi (Boehringer Ingelheim/Lilly), a fixed-dose combination of empagliflozin (Jardiance) and linagliptin (Tradjenta), for oral treatment of type 2 diabetes in adults. It is the first combination of a sodium-glucose co-transporter 2 (SGLT2) inhibitor and a dipeptidyl peptidase-4 (DPP-4) inhibitor to be approved in the US.

Immune globulin (IgG) has been available for administration intravenously once every 3-4 weeks or subcutaneously once daily, once weekly, or every 2 weeks for treatment of primary immunodeficiencies. Now the FDA has approved human immune globulin 10% with recombinant human hyaluronidase (HyQvia – Baxter) for subcutaneous administration only every 3-4 weeks in adults with these disorders. The IgG component of HyQvia is identical to Gammagard Liquid, which was approved in 2005 for IV administration and in 2011 for SC administration.

The FDA has approved Synjardy (Boehringer Ingelheim/Lilly), a fixed-dose combination of the sodium-glucose co-transporter 2 (SGLT2) inhibitor empagliflozin (Jardiance) and metformin (Glucophage, and others), for treatment of patients with type 2 diabetes not adequately controlled on either of these drugs alone or already being treated with both empagliflozin and metformin. It is the third SGLT2 inhibitor/metformin combination to be approved in the US.
