The FDA has licensed two new pneumococcal conjugate vaccines (PCVs) for prevention of invasive pneumococcal disease in adults: Prevnar 20 (PCV20; Pfizer), which contains antigens from 20 serotypes of pneumococcus, and Vaxneuvance (PCV15; Merck), which contains antigens from 15 serotypes. Two other pneumococcal vaccines are available in the US: Prevnar 13 (PCV13; Pfizer), a 13-valent conjugate vaccine licensed for use in persons ≥6 weeks old, and Pneumovax 23 (PPSV23; Merck), a 23-valent pneumococcal polysaccharide vaccine licensed for use in persons ≥2 years...

The drugs of choice for treatment of viral infections (other than HIV) and their dosages are listed in Tables 1-6 on the pages that follow. Some of the indications and dosages recommended here have not been approved by the FDA. Vaccines used for the prevention of viral infections are discussed elsewhere.

Becaplermin (be kap' ler min; Regranex - Ortho-McNeil), a 0.01% topical gel formulation of recombinant human platelet-derived growth factor (rhPDGF), was recently approved by the FDA for adjunctive treatment of diabetic ulcers of the lower extremities that extend subcutaneously or beyond and have an adequate blood supply. Endogenous platelet-derived growth factor increases proliferation of cells that repair wounds and form granulation tissue.

Pioglitazone is the third thiazolidinedione ("glitazone") to be marketed in the USA for treatment of type 2 diabetes. Thiazolidinediones decrease resistance to insulin.

The FDA now requires boxed warnings in the package inserts of benzodiazepines describing the potential for these drugs to be abused and misused and to cause addiction and physical dependence. Benzodiazepine labels have contained a boxed warning about a risk of serious drug interactions with opioids since 2016.

The direct oral anticoagulants (DOACs) apixaban (Eliquis) and rivaroxaban (Xarelto, and generics) are frequently used for treatment of acute venous thromboembolism (VTE) and are usually continued for at least 3 months. The other DOACs (edoxaban [Savaysa] and dabigatran [Pradaxa, and generics]) are alternatives for long-term treatment, but they require prior treatment with low-molecular-weight heparin for ≥5 days. Until recently, no large randomized trial directly comparing the safety of apixaban and rivaroxaban for treatment of VTE was available.

Oral antipsychotic drugs used for treatment of schizophrenia, schizoaffective disorder, delusional disorder, and other manifestations of psychosis or mania are listed in Table 1. Parenteral antipsychotic drugs used for treatment of these disorders are listed in Table 2.

In June 2021, the FDA approved the IV amyloid beta-directed monoclonal antibody aducanumab (Aduhelm) for treatment of Alzheimer’s disease. The approval did not restrict use of the drug to patients with mild cognitive impairment or mild dementia, which was the population enrolled in the clinical trials. Now, Biogen, with the permission of the FDA, has made an addition to the labeling of the drug that says: Treatment with Aduhelm should be initiated in patients with mild cognitive impairment or mild dementia stage of disease, the population in which treatment was initiated in clinical...

Consumption of alcohol has increased during the COVID-19 pandemic. The Diagnostic and Statistical Manual for Mental Disorders, 5th edition (DSM-5) defines alcohol use disorder (AUD; previously called alcohol dependence) as meeting ≥2 of the 11 criteria listed in Table 1 in the past year. The lifetime prevalence of AUD in the US population has been estimated to be about 30%. Despite this high prevalence and the associated morbidity, mortality, and costs, only 3 drugs are FDA-approved for treatment of the disorder.

The subcutaneously injected interleukin-13 (IL-13) antagonist tralokinumab-ldrm (Adbry – Leo) and the oral Janus kinase (JAK) inhibitors abrocitinib (Cibinqo – Pfizer) and upadacitinib (Rinvoq – Abbvie) have been approved by the FDA for treatment of moderate to severe atopic dermatitis.
