The FDA has approved Winlevi (Sun), a 1% cream formulation of the androgen receptor inhibitor clascoterone, for treatment of acne vulgaris in patients ≥12 years old. It is the first topical androgen receptor inhibitor to be approved by the FDA.

Proton pump inhibitors (PPIs), which are used for treatment of gastroesophageal reflux disease (GERD) and for prevention of upper gastrointestinal adverse effects caused by NSAIDs and aspirin, are one of the most commonly prescribed classes of drugs in the US. All PPIs are similarly effective and generally well tolerated, but their long-term use has been associated with a number of safety concerns. Recommendations addressing these concerns have recently been published.

The third sentence in the adverse effects section (Med Lett Drugs Ther 2015; 57:159) was incorrect. Cobicistat inhibits tubular secretion of creatinine, not reabsorption.

Nexplanon (Merck), a modified version of the contraceptive implant Implanon (Merck), is now available in the US. Nexplanon contains 68 mg of the progestin etonogestrel and is bioequivalent to Implanon. Both products are single-rod subdermal contraceptives implanted into the inside of the upper arm; both provide reversible effective contraception for up to 3 years.1 Nexplanon has a redesigned preloaded applicator intended to make insertion easier and reduce the risk of improperly placed devices. Proper placement is necessary to ensure adequate contraceptive efficacy and to facilitate future...

The FDA has approved a new injectable formulation of methotrexate (Otrexup – Antares) for use in rheumatoid arthritis and polyarticular juvenile idiopathic arthritis, and for severe psoriasis in adults. On its web site (www.otrexup.com), the manufacturer states: "Otrexup is the first subcutaneous (SC) methotrexate (MTX) for self-administration delivered once weekly by auto-injector." Methotrexate has been available as a once-weekly injection (IM or SC) for these indications for many years,1 but not specifically for self-administration and not in a single-dose auto-injector. Methotrexate is...

Combining a statin with another drug that lowers low-density lipoprotein cholesterol (LDL-C), such as colesevelam (Welchol), niacin (Niaspan, and others), or ezetimibe (Zetia), can reduce LDL-C levels more than a statin alone, but studies convincingly demonstrating that such combinations improve clinical outcomes have been lacking. The results of a long-term randomized, double-blind clinical trial (IMPROVE-IT) recently presented at the American Heart Association's Scientific Sessions 2014 indicate that addition of ezetimibe to simvastatin in high-risk patients reduces cardiovascular...

In our article on Bijuva, the oral fixed-dose combination of estradiol and progesterone (Med Lett Drugs Ther 2019; 61:99), Table 1 should have included single-ingredient oral formulations of estradiol and progesterone (see below). They will be added to the table as it appears online, along with medroxyprogesterone (Provera, and generics), another single-ingredient progestin available for use in women with an intact uterus who take systemic estrogen for menopausal symptoms. Taking generic estradiol and progesterone separately may be less convenient than taking Bijuva, but they cost less and...

In our article on abuse-deterrent opioids (Med Lett Drugs Ther 2017; 59:95), the information on Targiniq ER in Table 1 is incorrect. The drug, which is not available in the US, is a combination of oxycodone ER and naloxone, not naltrexone, and naloxone is dispersed throughout the tablet, not sequestered. Targiniq ER will be deleted from the table in the article as it appears on our website.

Idarubicin hydrochloride (Idamycin - Adria), an anthracycline structurally related to daunorubicin (Cerubidine, and others) and doxorubicin (Adriamycin, and others), was recently approved in the USA for treatment of acute myelogenous leukemia (AML) in adults.

Interferon β-1b (Betaseron - Berlex), an analog of human interferon β pro-duced in E. coli, may soon be approved by the US Food and Drug Administration for treatment of relapsing-remitting multiple sclerosis (MS), the most common form of the disease (G Mitchell, Med Clin North Am, 77:231, 1993).
