Electronic cigarettes, also called e-cigarettes, are battery-operated nicotine-delivery devices that resemble tobacco cigarettes. They deliver vapor containing a mixture of nicotine and either propylene glycol or glycerol. E-cigarettes are widely available in retail stores and on the internet in labeled strengths ranging from zero to high levels of nicotine and in flavors such as tobacco, mint, coffee, cherry, bubblegum, and chocolate. They are advertised as a healthier alternative to smoking a tobacco cigarette and, although not FDA-approved, as a smoking cessation tool.

Deep brain stimulation is FDA-approved and has been used for years to treat patients with advanced Parkinson's disease (PD) who have severe levodopa-induced motor complications. New evidence from a controlled trial suggests that it may also be effective for patients with PD and early motor complications.

With the widespread adoption of the CHA₂DS₂-VASc scoring system, oral anticoagulation therapy is now recommended for all patients ≥75 years old with nonvalvular atrial fibrillation. Atrial fibrillation has, however, been associated with an increased risk of falls, and older patients starting warfarin for atrial fibrillation have a high rate of hospitalization for intracranial bleeding. Many practitioners are reluctant, therefore, to prescribe an oral anticoagulant for elderly patients who are at high risk for falls.

The investigational neutralizing IgG1 monoclonal antibody bamlanivimab (LY-CoV555; Lilly) has been granted an FDA Emergency Use Authorization (EUA) for treatment of recently diagnosed mild to moderate COVID-19 in patients who are ≥12 years old, weigh at least 40 kg, and are at high risk for progressing to severe disease and/or hospitalization (see Table 1).

The FDA recently approved axicabtagene ciloleucel (Yescarta – Kite), a CD19-directed genetically modified cellular product, for treatment of large B-cell lymphoma that is refractory to first-line chemoimmunotherapy or that relapses within 12 months of first-line treatment. It was previously approved for treatment of relapsed or refractory B-cell lymphoma after ≥2 lines of systemic therapy and for treatment of relapsed or refractory follicular lymphoma after ≥2 lines of systemic therapy. Yescarta is an individualized cellular product prepared from the patient's own T cells,...

The FDA has approved lisocabtagene maraleucel (Breyanzi – BMS) for treatment of adults with large B-cell lymphoma (LBCL), including diffuse large B-cell lymphoma (DLBCL) not otherwise specified, high-grade B-cell lymphoma, primary mediastinal large B-cell lymphoma, or follicular lymphoma grade 3B who have disease refractory to first-line chemoimmunotherapy, relapsed within 12 months of or after first-line chemoimmunotherapy, are not eligible for hematopoietic stem cell transplantation due to comorbidities or age, or have relapsed or refractory disease after ≥2 lines of...

The FDA has approved Clenpiq (Ferring), a low-volume oral solution that contains sodium picosulfate, magnesium oxide, and anhydrous citric acid, for colon cleansing prior to colonoscopy in adults. The ready-to-drink solution contains the same ingredients as Prepopik, which is supplied as a powder for reconstitution.

Acesulfame potassium (Sunette - Hoechst), an oxathiazinondioxide, was recently approved by the US Food and Drug Administration (FDA) for use as a non-caloric table-top sweetener and as an ingredient in chewing gum, powdered beverages, gelatins and puddings. The other non-caloric artificial sweeteners available in the USA are saccharin (Sweet 'N Low; and others) and aspartame (NutraSweet; Equal) (Medical Letter, 24:1, 1982).

Two new substitutes for fat will soon be available in supermarkets in the USA, not directly, but incorporated into low-fat foods. Simplesse (NutraSweet) has already been approved for use by the US Food and Drug Administration (FDA) and is commercially available in some areas, but only in an ice-cream-like product called Simple Pleasures. Trailblazer (Kraft General Foods) is expected to be approved soon.

Breathe Right, an adhesive bandage device that pulls open the nostrils, has been approved by the US Food and Drug Administration and is being heavily promoted to the general public as a treatment for snoring and night-time nasal congestion. The manufacturer's suggested retail price is $4.99 for a box of 10 strips.
