The FDA has approved ustekinumab-auub (Wezlana – Amgen), an interchangeable biosimilar product similar to the interleukin-12 and -23 antagonist Stelara, for treatment of the same indications as Stelara (see Table 1). Wezlana is the first Stelara biosimilar to be approved in the US.

Lisdexamfetamine dimesylate (Vyvanse), a prodrug of dextroamphetamine previously approved for treatment of attention-deficit/hyperactivity disorder, has now been approved for treatment of moderate-to-severe binge eating disorder (recurrent episodes of compulsive overeating without purging) in adults.FDA approval of lisdexamfetamine for this indication was based on two unpublished, 12-week trials, summarized in the package insert, that randomized patients with moderate-to-severe binge eating disorder to lisdexamfetamine 30 mg/day, which was titrated to 50 mg or, if needed, 70 mg, or to placebo....

IV antiviral drug remdesivir (Veklury) has now been FDA-approved for treatment of COVID-19 in patients ≥28 days old who weigh ≥3 kg and are either hospitalized or at high risk for progression to severe disease. Remdesivir was already FDA-approved for these indications in patients ≥12 years old who weigh ≥40 kg; it was available under an Emergency Use Authorization (EUA) for younger or lighter patients. Remdesivir is the first drug to be FDA-approved for treatment of COVID-19 in children <12 years old.

Advertisements for atorvastatin (Lipitor), the market leader facing generic competition, have been in the news recently in the US. Lovastatin, pravastatin and simvastatin are all available generically at a much lower retail price or lower co-pay than atorvastatin.

A new formulation of the H1-antihistamine azelastine hydrochloride 0.1% nasal spray (Astepro - Meda) has been approved by the FDA for treatment of seasonal allergic rhinitis (SAR) in patients ≥12 years old and is being heavily advertised to the public on radio, television and the Internet. All azelastine products require a prescription.

Telavancin (Vibativ - Astellas and Theravance), a lipoglycopeptide derivative of vancomycin (Vancocin, and others), has received FDA approval for treatment of complicated skin and skin structure infections caused by susceptible gram-positive bacteria in adults.

Initial treatment of allergic rhinitis (AR) depends on the severity of symptoms and whether they are intermittent or persistent (see Table 1).

Standard approaches to therapy for gastroesophageal reflux disease (GERD) include lifestyle changes, over-the-counter and prescription drugs, and sometimes surgery. Emerging endoscopic anti-reflux procedures that are less invasive than surgery are potential additions to current treatment options. An endoscopicallyguided radiofrequency (RF) energy delivery system, Stretta (Curon Medical), was approved by the FDA for treatment of GERD in 2000.

Quantiferon - TB Gold (Cellestis) is a T-cell interferon-gamma release assay approved by the FDA as an alternative to the tuberculin skin test for diagnosis of infection with Mycobacterium tuberculosis (TB). An earlier assay (Quantiferon-TB), which is no longer commercially available, was approved by the FDA in 2001. Other interferon-gamma release assays (IGRAs) are available abroad.

Major orthopedic surgery creates a prothrombotic state by causing tissue injury during the operation and requiring relative immobilization during recovery. Without thromboprophylaxis, 40-60% of patients undergoing major knee or hip surgery develop venographically detectable deep vein thrombosis (DVT) and 1 in 300 undergoing total hip replacement will have a symptomatic pulmonary embolism (PE). Thromboprophylaxis reduces the incidence of venous thromboembolism (VTE), but it also can cause bleeding. New guidelines for prevention of VTE have recently been published.
