Plenity (Gelesis), a nonsystemic oral superabsorbent hydrogel formulation of cellulose and citric acid is now available. It was cleared by the FDA in 2019 to aid in weight management together with diet and exercise in overweight and obese adults (BMI of 25-40 kg/m2). It is classified by the FDA as a device because the contents of the capsule are not absorbed systemically. Plenity is the first ingested, transient, space-occupying hydrogel to be marketed in the US and the only weight management treatment available by prescription for patients with a BMI of 25-30 kg/m2, regardless of...

Nexplanon (Merck), a modified version of the contraceptive implant Implanon (Merck), is now available in the US. Nexplanon contains 68 mg of the progestin etonogestrel and is bioequivalent to Implanon. Both products are single-rod subdermal contraceptives implanted into the inside of the upper arm; both provide reversible effective contraception for up to 3 years.1 Nexplanon has a redesigned preloaded applicator intended to make insertion easier and reduce the risk of improperly placed devices. Proper placement is necessary to ensure adequate contraceptive efficacy and to facilitate future...

A new epinephrine auto-injector is available in the US (Auvi-Q – Sanofi; Allerject in Canada) for emergency treatment of anaphylaxis. The new device is about the length and width of a credit card and as thick as a smartphone. It has a retractable needle system and a red safety guard located at the same end as the needle. Activation of the device by removing the outer case initiates an audio voice recording that provides step-by-step instructions and a 5-second countdown during the injection. The shelf-life of the epinephrine in the auto-injector is 18 months; the shelf-life of the battery is...

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...

Inhaled antibiotics, which can achieve high concentrations in the lung with minimal systemic side effects, are probably the most effective therapy available for chronic Pseudomonas aeruginosa infection in patients with cystic fibrosis. An orally inhaled dry powder formulation of the aminoglycoside antibiotic tobramycin (Tobi Podhaler – Novartis) has been approved by the FDA for management of P. aeruginosa pulmonary infection in cystic fibrosis patients ≥6 years old. The new formulation is administered via a hand-held pocket-sized inhaler. Tobramycin is also available as an...

Tiotropium bromide inhalation powder (Spiriva HandiHaler - Boehringer Ingelheim), a long-acting anticholinergic agent, has been approved by the FDA for once-daily maintenance treatment of bronchospasm associated with chronic obstructive pulmonary disease (COPD). Available in Europe since 2002, it is the first long-acting inhaled anticholinergic drug for treatment of COPD. Ipratropium bromide (Atrovent), an anticholinergic used four times daily, has been available in the US for many years.

Annovera (TherapeuticsMD), a contraceptive vaginal ring that releases segesterone acetate, a synthetic progestin, and ethinyl estradiol, was approved by the FDA in 2018 and is now available. It is the first product to contain segesterone and the second vaginal ring to become available in the US; NuvaRing, which delivers etonogestrel and ethinyl estradiol, was the first. Unlike NuvaRing, which requires use of a new ring each month, the Annovera ring can be used for an entire year, but it must be removed for one week each month.

The FDA has approved nasal spray formulations of the benzodiazepines diazepam (Valtoco — Neurelis) and midazolam (Nayzilam — UCB) for acute treatment of intermittent episodes of frequent seizure activity (seizure clusters). Diazepam rectal gel (Diastat, Diastat AcuDial, and generics) has been used for this indication for many years.

Deep brain stimulation is FDA-approved and has been used for years to treat patients with advanced Parkinson's disease (PD) who have severe levodopa-induced motor complications. New evidence from a controlled trial suggests that it may also be effective for patients with PD and early motor complications.
