The oral kinase inhibitor capivasertib (Truqap – AstraZeneca), a first-in-class AKT inhibitor, has been approved by the FDA for use in combination with the selective estrogen receptor degrader (SERD) fulvestrant (Faslodex, and generics) for treatment of hormone receptor (HR)-positive, human epidermal growth factor receptor 2 (HER2)-negative, locally advanced or metastatic breast cancer in adults with one or more PIK3CA/AKT1/PTEN-alterations who had disease progression on at least one endocrine-based regimen for metastatic disease or recurrence on or within 12 months of completing...

Resmetirom (Rezdiffra – Madrigal), a thyroid hormone receptor-beta agonist, has received accelerated approval from the FDA for treatment of noncirrhotic nonalcoholic steatohepatitis (NASH) with moderate to advanced fibrosis in adults. NASH has recently been renamed metabolic dysfunction-associated steatohepatitis (MASH). Resmetirom is the first drug to be approved in the US for this indication.

Since 2007, antimicrobial prophylaxis for dental procedures has been recommended to prevent viridans group streptococcal infective endocarditis only for patients at highest risk of an adverse outcome. Limiting use to such patients does not appear to have led to an increased incidence of infective endocarditis or increased mortality due to infective endocarditis.

The FDA has approved the intravenously administered beta₁-adrenergic blocker landiolol (Rapiblyk – AOP) for short-term reduction of ventricular rate in adults with supraventricular tachycardia including atrial fibrillation and atrial flutter. Esmolol (Brevibloc, and generics), another IV beta blocker, was approved earlier for the same indication.

Aliskiren (ah LIS ker in; Tekturna - Novartis), the first direct renin inhibitor, has been approved by the FDA for treatment of hypertension. It is indicated for oral use either as monotherapy or in combination with other antihypertensive agents.

Infertility occurs in about 15% of couples. About one third of infertility is due to problems with ovulation or an anatomic abnormality of the fallopian tube or peritoneum, such as scarring, adhesions or endometriosis. Another third is due to a male infertility factor, most commonly insufficient sperm production or abnormal motility or morphology. The remaining third is unexplained. In older women unexplained infertility is probably caused by diminished quality and quantity of oocytes, decreased implantation and spontaneous pregnancy wastage.

The FDA has approved istradefylline (Nourianz — Kyowa Kirin), an oral adenosine A_2A receptor antagonist, for use as an adjunct to carbidopa/levodopa in adults with Parkinson's disease (PD) who experience "off" episodes. Istradefylline is the first adenosine A_2A receptor antagonist to be approved in the US; it has been available in Japan since 2013.

In addition to surgery and radiation therapy, a variety of drugs are used both singly and in combination to treat breast cancer. This article summarizes the principles of adjuvant therapy and treatment for metastatic disease. A summary of individual drugs and their adverse effects begins on page 3.

The drugs of choice for treatment of common cardiac arrhythmias are listed in Tables 1 and 2. Some drugs are recommended for indications that have not been approved by the FDA.

Production of erythropoietin, a glycoprotein hormone secreted mainly by the kidney, is often low in patients with chronic renal failure (JW Eschbach, Kidney Int, 35:134, 1989). The US Food and Drug Administration recently approved marketing of epoetin alfa (Epogen - Amgen), a recombinant human erythropoietin, for treatment of anemia in such patients. Epoetin is commercially available in Europe as Eprex (Ortho), and Eprex is available from Ortho in the USA on an investigational basis for treatment of anemia related to AIDS. Epogen and Eprex are chemically...
