The oral kinase inhibitors dabrafenib (Tafinlar – GSK) and trametinib (Mekinist – Novartis) have been approved by the FDA for use together for a sixth indication: treatment of low-grade glioma (LGG) with a BRAF V600E mutation in patients ≥1 years old who require systemic therapy. This combination is the first systemic therapy to be approved in the US for first-line treatment of LGG with a BRAF V600E mutation in pediatric patients. The FDA also approved new oral formulations of both drugs for patients who are unable to swallow dabrafenib capsules or trametinib...

Lansoprazole (Prevacid -TAP), a proton pump inhibitor similar to omeprazole (Prilosec - Medical Letter, 32:19, 1990), has been approved by the US Food and Drug Administration for short-term treatment of active duodenal ulcer and erosive reflux esophagitis and for long-term treatment of chronic hypersecretory conditions, including the Zollinger-Ellison syndrome.

In the recent Medical Letter article on the treatment of Clostridium difficile–associated disease (CDAD) we wrote: “Healthcare workers caring for patients with C. difficile infection should follow contact isolation precautions, especially use of gloves and hand washing with soap and water after glove removal. Alcohol-based products such as hand sanitizers will not eradicate C. difficile spores.”1 One reader pointed out that alcoholbased products do eradicate some C. difficile spores and have been invaluable against other pathogens.In an unpublished study available as an abstract, both...

The FDA has approved vismodegib (vis moe deg´ ib; Erivedge – Genentech), the first hedgehog (Hh) pathway inhibitor, for oral treatment of metastatic basal cell cancer, locally advanced basal cell carcinoma that has recurred after surgery, or locally advanced basal cell carcinoma in adults who are not candidates for surgery or radiation.

Recently pharmaceutical manufacturers have marketed a stereoisomer of a successful drug nearing patent expiration as a new drug. Examples, such as esomeprazole (Nexium) , levalbuterol (Xopenex), escitalopram (Lexapro) and dexmethylphenidate

The FDA has approved a subcutaneously injected formulation of recombinant human parathyroid hormone (Natpara – NPS) as an adjunct to calcium and vitamin D to control hypocalcemia in adults with hypoparathyroidism. Natpara is an 84-amino acid single-chain polypeptide identical to native parathyroid hormone. It is the first parathyroid hormone formulation to be approved for this indication.

About 2.5 million persons in the US had hepatitis C between 2017 and 2020. Guidelines from the American Association for the Study of Liver Diseases (AASLD) and the Infectious Diseases Society of America (IDSA) on management of hepatitis C virus (HCV) infection were updated in 2023.

The FDA has approved two new oral kinase inhibitors for treatment of unresectable or metastatic melanoma: dabrafenib (Tafinlar – GSK) for melanomas with BRAF V600E mutations and trametinib (Mekinist – GSK) for melanomas with either BRAF V600E or V600K mutations. Dabrafenib is not recommended for patients with wild-type BRAF (BRAF-negative) melanoma, and trametinib is not recommended for patients who have received prior BRAF-inhibitor therapy.

The oral kinase inhibitors dabrafenib (Tafinlar – GSK) and trametinib (Mekinist – Novartis) have received accelerated approval by the FDA for use together for a fifth indication: treatment of unresectable or metastatic solid tumors with a BRAF V600E mutation in patients ≥6 years old who have progressed following prior treatment and have no satisfactory alternative treatment options. The combination is not approved for treatment of colorectal cancer because of known intrinsic resistance to BRAF inhibition and dabrafenib is not approved for use in patients with wild-type BRAF...

Primary hypothyroidism is usually the result of Hashimoto's (autoimmune) thyroiditis, thyroidectomy, or radioactive iodine therapy. Treatment of hypothyroidism with replacement doses of thyroid hormone is usually lifelong. Levothyroxine (LT4; synthetic thyroxine; Synthroid, and others) is the drug of choice.1
