The FDA, which had previously approved intravenous (IV) administration of 5 mg of zoledronic acid (Reclast – Novartis) once a year for treatment of postmenopausal osteoporosis (Med Lett Drugs Ther 2007; 49:89), has now approved the same dose for use once every 2 years to prevent osteoporosis in postmenopausal women with osteopenia.Clinical Studies – In an unpublished study summarized in the package insert, 224 women with osteopenia ≤5 years after menopause were given an IV infusion of zoledronic acid 5 mg or placebo; 2 years later, total hip bone mineral density (BMD) had increased by...

Transdermal fentanyl (Duragesic, and others) offers a convenient delivery system for patients with chronic pain1 but it has some drawbacks. One is that exposing the patch to heat, either from an external source, increased exertion or possibly high fever, could increase release of the drug, which might lead to an overdose and fatal respiratory depression.2 A recent article in the NY Times about this problem may have aroused the concerns of some patients using the patches.3First approved for marketing by the FDA in 19914, transdermal fentanyl provides continuous delivery of the drug for about 3...

Linagliptin (Tradjenta – Boehringer Ingelheim/Lilly), a third oral dipeptidyl peptidase-4 (DPP-4) enzyme inhibitor, was recently approved by the FDA for treatment of type 2 diabetes, either alone or in combination with metformin, a sulfonylurea or pioglitazone

The main purpose of vasopressors is to raise arterial blood pressure, while that of inotropes is to increase cardiac contractility. The choice of drugs is dictated by the clinical setting. Controlled trials comparing the efficacy and safety of these drugs are generally lacking.

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.

At the same time that the FDA announced it was strengthening existing warnings about the risk of acute kidney injury in patients with type 2 diabetes treated with the sodium-glucose co-transporter 2 (SGLT2) inhibitors canagliflozin (Invokana, and others) and dapagliflozin (Farxiga, and others), a study was published showing that the third SGLT2 inhibitor, empagliflozin (Jardiance, and others), slowed the progression of renal dysfunction in patients with type 2 diabetes.

Development of abuse-deterrent opioid products, including reformulation of existing products, has become a priority for drug manufacturers and public health advocates. Since our last article on this subject, several new abuse-deterrent opioid formulations have been approved by the FDA, including an oxycodone tablet formulation (Roxybond – Inspirion) that is the first immediate-release opioid product FDA-approved to include claims of abuse deterrence in its labeling. No opioid formulation prevents consumption of a large number of intact dosage units, the most common method of...

The FDA has approved an extended-release tablet formulation of amantadine (Osmolex ER – Vertical/Osmotica) for once-daily treatment of Parkinson's disease (PD) and drug-induced extrapyramidal symptoms (EPS) in adults. An extended-release capsule formulation of amantadine (Gocovri) was approved in 2017 for treatment of levodopa-induced dyskinesia in patients with PD.

The FDA has approved anifrolumab-fnia (Saphnelo – AstraZeneca), a type I interferon receptor antagonist, for IV treatment of adults with moderate to severe systemic lupus erythematosus (SLE) who are receiving standard treatment. Anifrolumab has not been studied in patients with severe active lupus nephritis or severe active CNS lupus. It is the first type I interferon receptor antagonist to become available in the US.

Lecanemab-irmb (Leqembi – Biogen/Eisai), an IV amyloid beta-directed monoclonal antibody, has received accelerated approval from the FDA for treatment of Alzheimer's disease. The label states that treatment with Leqembi should be initiated in patients with mild cognitive impairment (MCI) or mild dementia, the population in which the drug was initiated in clinical trials. Lecanemab is the second IV amyloid-beta directed monoclonal antibody to be approved for this indication; aducanumab (Aduhelm) was approved in 2021 and has the same restrictions on treatment...
