The FDA has approved a once-weekly extendedrelease formulation of exenatide (Bydureon – Amylin), an injectable glucagon-like peptide-1 (GLP-1) receptor agonist, for treatment of type 2 diabetes.

In 2012, the FDA required manufacturers of HMG-CoA reductase inhibitors (statins) to add a warning to their labels about reports of increased blood glucose and glycosylated hemoglobin (HbA1c) levels. Since then, several new studies have been published.

The FDA has approved Xtampza ER (Collegium), a new extended-release, abuse-deterrent capsule formulation of oxycodone, for management of pain severe enough to require daily, around-the-clock, long-term opioid treatment and for which alternative treatment options are inadequate.

A reader has questioned why the label for the COX-2 selective NSAID celecoxib (Celebrex, and generics), which contains a sulfonamide moiety, states that it is contraindicated for use in patients with an allergy to sulfonamides, while the labels of some other sulfonamide drugs recommend either caution or no precautions at all. The concept of cross-reactivity among sulfonamide drugs, particularly between antibacterial and nonantibacterial sulfonamides, has been controversial for many years.

The FDA has approved a progestin-only oral contraceptive ("minipill") containing drospirenone (Slynd – Exeltis). All other progestin-only oral contraceptives available in the US contain norethindrone (Camila, and others). Progestin-only oral contraceptives are similar in efficacy to combination oral contraceptives. They are used predominantly by breastfeeding women and by those in whom estrogen is poorly tolerated or contraindicated. Combination oral contraceptives containing drospirenone and ethinyl estradiol have been available for years.

Maribavir (Livtencity – Takeda), an oral cytomegalovirus (CMV) pUL97 kinase inhibitor, has been approved by the FDA for treatment of post-transplant CMV infection refractory to standard antiviral therapy in patients ≥12 years old who weigh at least 35 kg.

Colchicine (Colcrys, and others), which has been available in the US for decades for prophylaxis and treatment of gout flares and other indications in oral formulations that contain 0.6 mg of the drug, has now been approved in 0.5-mg tablets as Lodoco (Agepha) to reduce the risk of myocardial infarction (MI), stroke, coronary revascularization, and cardiovascular death in adults with established atherosclerotic disease or multiple risk factors for cardiovascular disease.

The FDA has approved the oral tyrosine kinase inhibitor repotrectinib (Augtyro – BMS) for treatment of locally advanced or metastatic ROS1-positive non-small cell lung cancer (NSCLC) in adults. Repotrectinib is the third oral tyrosine kinase inhibitor to be approved for this indication in the US; crizotinib (Xalkori) and entrectinib (Rozlytrek) were approved earlier.

The FDA has approved cariprazine (Vraylar – Actavis), an oral, once-daily, second-generation antipsychotic, for treatment of schizophrenia and for acute treatment of manic or mixed episodes associated with bipolar I disorder.

The FDA has warned that use of an SGLT2 (sodium-glucose co-transporter 2) inhibitor for treatment of type 2 diabetes may lead to ketoacidosis.1 Three SGLT2 inhibitors, canagliflozin (Invokana, Invokamet), dapagliflozin (Farxiga, Xigduo XR), and empagliflozin (Jardiance, Glyxambi), are approved for treatment of type 2 diabetes in the US. Between March 2013 and June 2014, 20 cases of ketoacidosis requiring emergency room visits or hospitalization were reported in patients who had recently started taking an SGLT2 inhibitor; the median time to onset of symptoms after initiation of therapy was 2...
