The FDA has approved ferric citrate (Auryxia – Keryx), an oral phosphate binder, for treatment of hyperphosphatemia in patients with chronic kidney disease (CKD) on dialysis. It is the second iron-based phosphate binder to be approved in the US, and the first that causes significant systemic absorption of iron. Auryxia is not FDA-approved for treatment of iron deficiency anemia.

The FDA has approved the nonsteroidal mineralocorticoid receptor antagonist (MRA) finerenone (Kerendia) to reduce the risk of cardiovascular death, hospitalization for heart failure (HF), and urgent HF visits in adults with HF with a left ventricular ejection fraction (LVEF) ≥40%. Finerenone was approved in 2021 to reduce the risk of kidney disease progression and cardiovascular events in adults with chronic kidney disease (CKD) associated with type 2 diabetes.

Some readers have objected to our recommendation (Med Lett Drugs Ther 2013; 55:55) that postmenopausal women with an intact uterus who take the oral estrogen agonist/antagonist ospemifene (Osphena) to reduce the severity of dyspareunia should also take a progestin.1 Ospemifene has agonistic effects on the endometrium, and the Osphena package insert says: "Generally, when a product with estrogen agonistic effects on the endometrium is prescribed for a postmenopausal woman with a uterus, a progestin should be considered to reduce the risk of endometrial cancer."Endometrial hyperplasia has been...

Betaxolol (Kerlone - Searle), an oral beta-adrenergic blocker, was recently approved by the US Food and Drug Administration for once-daily treatment of hypertension. The new drug is beta 1 (cardio)-selective with no intrinsic sympathomimetic (partial agonist) activity. It is also available in a topical formulation for treatment of glaucoma (Betoptic - Medical Letter, 28:45, 1986). Beta-blockers currently available in the USA for treatment of hypertension are listed in the table below.

Losartan potassium (Cozaar - Merck), the first angiotensin II receptor antagonist, has been approved for oral treatment of hypertension by the US Food and Drug Administration. It will be marketed both alone and in a fixed-dose combination with the diuretic hydrochlorothiazide (Hyzaar).

Vardenafil (Levitra -Bayer) is the second oral drug approved by the FDA for treatment of erectile dysfunction. Sildenafil (Viagra - Medical Letter 1998; 40:51), the first oral drug, has been available for 5 years. Pharmacokinetics, effectiveness, adverse effects, dosage and cost of the new drug are reviewed. Whether it offers any benefits over sildenafil is discussed.

The investigational monoclonal antibody sotrovimab (VIR-7831; GSK/Vir Biotechnology) has been granted an FDA Emergency Use Authorization (EUA) for treatment of mild to moderate COVID-19 in patients ≥12 years old who weigh ≥40 kg and are at high risk of progressing to severe disease, including hospitalization and death.1 Two other monoclonal antibody regimens are authorized for the same indication: casirivimab (REGN10933) and imdevimab (REGN10987) administered together, and bamlanivimab (LY-CoV555) and etesevimab (LYCoV016) administered together. The FDA revoked its EUA...

Inclisiran (Leqvio – Novartis), a subcutaneously injected small interfering RNA (siRNA) that decreases LDL-cholesterol (LDL-C) levels by reducing synthesis of proprotein convertase subtilisin/kexin type 9 (PCSK9), has been approved by the FDA for use with or without a statin to reduce LDL-C in adults with hypercholesterolemia, including heterozygous familial hypercholesterolemia (HeFH). Inclisiran had previously been approved for use only in combination with statin therapy.

Fibrates, niacin and fish oil are promoted for treatment of hypertriglyceridemia. HMG-CoA reductase inhibitors (statins) can lower elevated serum concentrations of triglycerides, but less so than fibrates, niacins or fish oil. Lifestyle changes such as weight reduction, exercise and decreasing alcohol intake can also lower serum triglyceride levels and should be tried first.

Pharmacologic management of chronic heart failure (HF) is primarily determined by the patient's left ventricular ejection fraction (LVEF) and severity of symptoms. Patients with chronic HF who have an LVEF ≤40% are considered to have heart failure with reduced ejection fraction (HFrEF) and those with an LVEF ≥50% are considered to have heart failure with preserved ejection fraction (HFpEF). Patients with an LVEF of 41-49% have heart failure with mildly reduced or mid-range ejection fraction.
