The FDA has approved iDose TR (Glaukos), an intracameral implant containing the prostaglandin analog (PGA) travoprost, for reduction of intraocular pressure (IOP) in patients with open-angle glaucoma or ocular hypertension. Travoprost is also available as a topical ophthalmic solution (Travatan Z, and generics) for the same indication. iDose TR is the second ocular implant to become available in the US for this indication; Durysta, an intracameral implant containing the prostaglandin analog bimatoprost, was the first.

Implantable cardioverter defibrillators (ICDs) are widely used in patients at risk for sudden cardiac death (SCD) because these devices have been highly successful in terminating life-threatening ventricular arrhythmias and in increasing survival.

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 (DBS) is increasingly used to treat advanced Parkinson's disease (PD), but few controlled clinical trials have been published. New evidence from a large controlled study has recently become available.

Sudden cardiac arrest has a survival rate of about 6% without immediate defibrillation. Automated external defibrillators (AEDs) can be found in many public locations such as shopping malls, office buildings and schools. Some patients may ask their physicians whether they should purchase an AED for personal use. One device has been FDA-approved for sale over the counter (HeartStart Home Defibrillator - Philips). Purchase of all other AEDs for public places or home use requires authorization from a physician.

The recent attack in the Tokyo subway has led to many questions about the clinical effects, treatment and prevention of nerve gas poisoning.

Systemic allergic reactions to insect stings can include generalized urticaria, bronchospasm, laryngeal edema, hypotension and death. About 1% to 3% of adults in the USA have had a systemic allergic reaction to an insect sting (RE Reisman, Med Clin North Am, 76:883, 1992; UR M ller, Monogr Allergy, 31:131, 1993).

Zanamivir, a neuraminidase inhibitor taken by inhalation, has been approved by the FDA for treatment of influenza. Oseltamivir phosphate, an oral neuraminidase inhibitor, will probably be approved soon.

The FDA has approved an inhaled fixed-dose combination of the long-acting anticholinergic umeclidinium (ue mek" li din' ee um) and the long-acting beta₂-adrenergic agonist (LABA) vilanterol (Anoro Ellipta – GSK/Theravance) for once-daily maintenance treatment of chronic obstructive pulmonary disease (COPD). Anoro Ellipta is the first product available in the US that combines two long-acting bronchodilators in a single delivery device.

The FDA has approved indacaterol (in´´ da ka´ ter ol; Arcapta Neohaler – Novartis), an inhaled long-acting beta₂-agonist, for once-daily maintenance treatment of airflow obstruction in patients with chronic obstructive pulmonary disease (COPD). Indacaterol is not approved for treatment of exacerbations of COPD or for treatment of asthma. It has been available in Europe as Onbrez Breezhaler since 2009.
