The FDA has added a boxed warning to fluoroquinolone package inserts about tendon injuries that may occur as a result of their use. Tendinitis or tendon rupture may occur rarely with systemic use of any fluoroquinolone, either while the drug is being taken or for up to several months afterwards.Fluoroquinolone-related tendon injury is rare; estimates for its incidence in the general population range from 0.14% to 0.4%. The risk is higher for patients >60 years old and for those taking corticosteroids. For patients with organ transplants, the incidence may be as high as 15%.1 A case-control...

An article published in the New York Times on May 1, 2015 listed the 10 drugs on which Medicare Part D spent the most in 2013. The most costly ($2.53 billion) was the proton pump inhibitor (PPI) Nexium (esomeprazole magnesium), which has recently become available generically.

The FDA has approved Trijardy XR (Boehringer Ingelheim/Lilly), a fixed-dose combination of the sodium-glucose cotransporter 2 (SGLT2) inhibitor empagliflozin, the dipeptidyl peptidase-4 (DPP-4) inhibitor linagliptin, and extended-release metformin, for oral treatment of type 2 diabetes in adults. Empagliflozin and linagliptin have been available in a fixed-dose combination as Glyxambi since 2015, and both have been available in 2-drug combinations with extended-release metformin for years (see Table 1).

The FDA has approved a 0.25% ophthalmic solution of the ectoparasiticide lotilaner (Xdemvy – Tarsus) for treatment of Demodex blepharitis. Lotilaner is the first drug to be approved in the US for this indication.

Bexagliflozin (Brenzavvy – TheracosBio), a sodium-glucose cotransporter 2 (SGLT2) inhibitor, has been approved by the FDA to improve glycemic control in adults with type 2 diabetes. It is the fifth SGLT2 inhibitor to be approved in the US for this indication (see Table 4).

Aspirin is now widely used for antithrombotic prophylaxis in patients who have had angina pectoris or a myocardial infarction and has also been tried in healthy people to prevent myocardial infarction. Recent studies have focused on increasingly lower doses of the drug. The use of aspirin in patients who have had transient ischemic attacks or strokes will not be discussed here.

Belzutifan (Welireg – Merck), a first-in-class hypoxia-inducible factor inhibitor, has been approved by the FDA for treatment of advanced renal cell carcinoma (RCC) in adults who received prior treatment with a programmed death receptor-1 (PD-1) or programmed death-ligand 1 (PD-L1) inhibitor and a vascular endothelial growth factor tyrosine kinase inhibitor (VEGF-TKI). Belzutifan was previously approved for use in patients with von Hippel-Lindau disease.

The FDA has required labeling changes that replace serum creatinine (SCr) with estimated glomerular filtration rate (eGFR) as the parameter used to determine the appropriateness of treatment with the biguanide metformin (Glucophage, and others) in patients with renal impairment. These changes will allow more patients with mild to moderate renal impairment to receive metformin, which is generally the first drug prescribed for treatment of type 2 diabetes.Metformin was previously contraindicated in women with a SCr level ≥1.4 mg/dL and in men with a SCr level ≥1.5 mg/dL, but use of SCr as a...

The results of a clinical trial (PRECISION) comparing the cardiovascular safety of the COX-2 selective NSAID celecoxib (Celebrex, and generics) with that of ibuprofen and naproxen, which are nonselective, have been described in the lay press in terms that may overestimate the safety of celecoxib.
