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

Losartan potassium (Cozaar - Merck), the first angiotensin II receptor antagonist, has been approved for oral treatment of hypertension by the US Food and Drug Administration. It will be marketed both alone and in a fixed-dose combination with the diuretic hydrochlorothiazide (Hyzaar).

Pramipexole (Mirapex - Pharmacia & Upjohn) and ropinirole (Requip - SmithKline Beecham), two new dopamine agonists, have been approved by the US Food and Drug Administration (FDA) for treatment of both early (without levodopa) and advanced (with levodopa) Parkinson's disease. Bromocriptine (Parlodel) and pergolide (Permax) are older dopamine agonists marketed in the USA for adjunctive use with levodopa.

Repaglinide (Prandin - Novo Nordisk) is a new oral glucose-lowering agent for treating type 2 diabetes (formerly called non-insulin-dependent diabetes mellitus or NIDDM). It has been approved by the FDA for monotherapy or for use in combination with metformin.

Fenoldopam mesylte (Corlopam - Neurex), a peripheral dopamine-1 (DA₁) agonist, has been approved by the FDA for parenteral use in lowering blood pressure. The manufacturer claims that, unlike other parenteral antihypertensive agents, fenoldopam not only lowers blood pressure but also maintains or improves renal function.

Older patients are especially susceptible to drug-induced cognitive impairment. They are more likely to be taking multiple drugs, to have higher blood levels of those drugs because of renal or hepatic dysfunction, and to have pre-existing cognitive problems that make it difficult to detect the role of drugs causing new symptoms or making old ones worse.

Aripiprazole (Abilify - Bristol-Myers Squibb/Otsuka), a second-generation (atypical) antipsychotic drug, was approved by the FDA in 2002 for treatment of schizophrenia and more recently for bipolar disorder as well. It has been promoted as causing fewer adverse effects than other antipsychotics, without sacrificing efficacy.

The FDA has approved ticagrelor (Brilinta – AstraZeneca), an oral antiplatelet drug, for use with low-dose aspirin to reduce the rate of thrombotic cardiovascular events in patients with acute coronary syndrome (ACS). It will compete with clopidogrel (Plavix) and prasugrel (Effient) for such use. Clopidogrel is expected to become available generically in the US within the next few months.

The FDA has approved pomalidomide (Pomalyst – Celgene), an oral thalidomide analog, for treatment of patients with multiple myeloma who have received at least 2 prior therapies including lenalidomide (Revlimid) and bortezomib (Velcade) and whose disease had progressed on or within 60 days of completion of the last therapy.

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.
