A new enteric-coated delayed-release formulation of risedronate (Atelvia – Warner Chilcott) has been approved by the FDA for treatment of postmenopausal osteoporosis. Unlike immediate-release risedronate (Actonel) and all other oral bisphosphonates, which must be taken after an overnight fast and at least 30 minutes before eating breakfast, the new formulation is taken immediately after breakfast with at least 4 ounces of water. Then the patient must remain upright for at least 30 minutes.CLINICAL TRIAL — Approval of Atelvia was based on a 52-week non-inferiority study in more than 900...

A randomized, placebo-controlled trial evaluating the addition of the direct renin inhibitor aliskiren (Tekturna – Novartis) to an angiotensin-converting enzyme (ACE) inhibitor or angiotensin receptor blocker (ARB) in 8606 patients with type 2 diabetes and renal impairment (ALTITUDE) was terminated prematurely by the manufacturer because the combined incidence of cardiovascular and renal events was higher in patients who received aliskiren than in those who received placebo.1Combining two different types of drugs that block the renin angiotensin system in patients at high-risk for...

The FDA has approved a new extended-release capsule formulation of topiramate (Qudexy XR – Upsher Smith), which can be opened and sprinkled on food for patients who have difficulty swallowing tablets or capsules, for treatment of epilepsy. Qudexy XR was marketed as a branded drug in March 2014 and as a generic drug four months later.

In 2007, an FDA advisory committee asked that placebo-controlled, dose-ranging trials be conducted to establish the efficacy of the oral decongestant phenylephrine (Sudafed PE, and others), which is sold over the counter (OTC) as a single agent and in combination with other drugs for treatment of cold and allergy symptoms. Phenylephrine replaced pseudoephedrine (Sudafed, and others) in many OTC formulations when access to pseudoephedrine-containing products was restricted in an effort to reduce their use in the synthesis of methamphetamine.CLINICAL STUDIES — In a randomized, open-label,...

The once-monthly, subcutaneously injected calcitonin gene-related peptide (CGRP) receptor antagonist erenumab-aooe (Aimovig) was approved by the FDA in 2018 for preventive treatment of migraine in adults. Now the FDA has added a new warning to its labeling about a risk of new-onset hypertension and worsening of preexisting hypertension associated with use of the drug. CGRP is a potent microvascular vasodilator; blocking or deleting it has produced hypertensive effects in animals.

The FDA has approved release of omalizumab (oh mah lye zoo mab; Xolair - Genentech, Novartis), a humanized monoclonal antibody given subcutaneously that binds to immunoglobulin E (IgE). The drug is labeled for patients at least 12 years old with moderate to severe persistent asthma who have shown reactivity to an allergen and whose symptoms are inadequately controlled by an inhaled corticosteroid. The manufacturer claims the drug can help stop allergic reactions before they begin.

The FDA recently approved the monoamine oxidase inhibitor (MAOI) selegiline in a transdermal (patch) formulation (Emsam - Bristol-Myers Squibb/Somerset) for treatment of major depressive disorder.

ThermaClear is indicated only for use on mild to moderate inflammatory acne, not severe nodular or severe cystic acne, and it is not meant to be used on blackheads and whiteheads. Two similar devices are already on the market: Zeno, another handheld device that delivers heat to acne lesions, and the Radiancy Clear Touch Lite Acne Clearance System, a larger heat-delivery device.

Ruxolitinib (Jakafi) is the only other JAK inhibitor available in the US; it is FDA-approved for treatment of myelofibrosis.
