The FDA has approved rivaroxaban (Xarelto – Janssen), an oral direct factor Xa inhibitor, for prevention of deep vein thrombosis (DVT) in patients undergoing knee or hip replacement surgery.

The FDA has approved the oral kinase inhibitor quizartinib (Vanflyta – Daiichi Sankyo) for use in combination with standard cytarabine and anthracycline induction and cytarabine consolidation, and as maintenance monotherapy following consolidation chemotherapy in adults with FLT3 internal tandem duplication (ITD)-positive, newly-diagnosed acute myeloid leukemia (AML).

The FDA has recently approved intradetrusor injection of onabotulinumtoxinA (Botox – Allergan) for treatment of overactive bladder in patients who cannot tolerate or have an inadequate response to anticholinergic therapy. Botox is also approved by the FDA for use in detrusor overactivity associated with a neurologic condition such as multiple sclerosis or spinal cord injury, and for chronic migraine, upper limb spasticity, axillary hyperhidrosis, cervical dystonia, blepharospasm, strabismus, and cosmetic reduction of wrinkles.

The FDA has approved sugammadex (Bridion – Merck), a selective relaxant binding agent, for reversal of rocuronium- or vecuronium-induced neuromuscular blockade in adult surgical patients. It is the first selective relaxant binding agent to be approved in the US. Sugammadex has been available in the European Union, Japan, and elsewhere for several years. Previous FDA reviews of sugammadex did not result in approval because of concerns about a risk of anaphylaxis and other hypersensitivity reactions with its use.

The FDA has approved Cinvanti (Heron), an IV emulsion formulation of the substance P/neurokinin-1 (NK1) receptor antagonist aprepitant, for prevention of acute and delayed chemotherapy-induced nausea and vomiting (CINV) in adults. Aprepitant is also available in oral capsule and suspension formulations (Emend, and generics), and fosaprepitant, a prodrug of aprepitant, is available in an IV formulation (Emend for injection).

Spinal decompression machines offer a motorized form of mechanical traction. These devices, which are widely advertised to the public as a noninvasive alternative to surgery, are claimed to relieve low back pain by decompressing discs, improving the flow of nutrients into the disc and rehydrating dried-out discs. Devices cleared by the FDA based on substantial similarity to previously approved power traction devices include the Accu- Spina System, DRS System, DRX9000, Lordex Traction Unit, Spinal Health Elite, SpineMED Decompression Table, SpineRx-LDM and VAX-D Therapeutic Table.

Two cell-based gene therapies – exagamglogene autotemcel (Casgevy – Vertex) and lovotibeglogene autotemcel (Lyfgenia – Bluebird Bio) – have been approved by the FDA for treatment of sickle cell disease in patients ≥12 years old with recurrent vaso-occlusive crises. They are the first gene therapies to be approved in the US for use in sickle cell disease; Casgevy is the first treatment to be approved in the US that uses CRISPR/Cas9 gene-editing technology.

Onychomycosis is caused most commonly by Trichophyton rubrum or T. mentagrophytes. About 10% of all persons worldwide and 40% of those ≥60 years old are believed to have the disease. Risk factors include older age, diabetes, poor peripheral circulation, smoking, HIV infection, psoriasis, and immunosuppression. Left untreated, onychomycosis can cause nail plate destruction, ingrown nails, and (particularly in patients with diabetes) secondary infections. Guidelines on treatment of onychomycosis have been published.

Cisapride (Propulsid - Janssen), a piperidinyl benzamide prokinetic drug, is now available in the USA for symptomatic relief of nocturnal heartburn due to gastroesophageal reflux disease. In Canada, cisapride is also marketed for treatment of gastroparesis.

Lubiprostone (Amitiza), which was previously approved for treatment of chronic idiopathic constipation in adults, has now also been approved in a lower dose for use in women with irritable bowel syndrome with constipation (IBS-C). Since tegaserod (Zelnorm) has been withdrawn from the market,2 lubiprostone is the only drug approved by the FDA for treatment of this common condition.
