The FDA has approved a new tablet formulation of bromocriptine mesylate (Cycloset – VeroScience) for treatment of type 2 diabetes in adults. Bromocriptine (Parlodel, and others) is an ergot-derived dopamine agonist that has been used for more than 20 years to treat hyperprolactinemia, acromegaly, Parkinson’s disease and restless leg syndrome.

Rasagiline (Azilect - Teva), a monoamine oxidase-type B (MAO-B) inhibitor, was recently approved by the FDA for once-daily oral treatment of Parkinson's disease (PD). It can be taken alone for treatment of early disease or with levodopa/carbidopa (Sinemet, and others) for advanced disease. Selegiline (Eldepryl, and others), the first MAO-B inhibitor marketed in the US, has been available since 1988; a new lower-dose disintegrating tablet (Zelapar) was recently approved.

Ever-increasing specialization has made it difficult for many physicians to keep up with therapeutic standards in intensive-care units (ICUs). This issue of Treatment Guidelines offers current recommendations for use of cardiovascular drugs in the ICU for treatment of hypertensive emergencies; shock, cardiac arrest or decompensated heart failure; and ventricular arrhythmias.

Controlled-release carbidopa/levodopa (Sinemet CR - Dupont Pharma) was recently approved by the US Food and Drug Administration for treatment of Parkinson's disease. The new formulation of this old combination (Sinemet) has the drugs suspended in a polymeric matrix that erodes slowly in the gastrointestinal tract.

Aripiprazole (Abilify - Bristol-Myers Squibb/Otsuka), a quinolinone derivative, has been approved by the FDA for treatment of schizophrenia.

Armodafinil (Nuvigil – Cephalon), the R-enantiomer of the non-amphetamine stimulant modafinil (Provigil – Cephalon; Alertec – Shire in Canada), is being promoted directly to the public for treatment of excessive daytime sleepiness associated with shift work.

Cabergoline (Dostinex - Pharmacia & Upjohn), an ergot alkaloid derivative recently marketed for treatment of hyperprolactinemia, is a selective D2 dopamine agonist that inhibits prolactin-secreting cells in the pituitary. Bromocriptine (Parlodel - Sandoz), the drug most commonly used for this condition, is also a D2 agonist, but affects D1 receptors as well.

A patch formulation of the non-ergot dopamine agonist rotigotine (Neupro – UCB) has returned to the US market after a 4-year absence. Originally approved by the FDA in 2007 for treatment of early Parkinson’s disease,1 it was withdrawn in 2008 because of crystallization of the drug in the patch, which could have led to under-dosing. The new patch has somewhat broader indications than the old one; it is approved for use in any stage of Parkinson’s disease (PD) and also for moderate-to-severe restless legs syndrome (RLS).1. Transdermal rotigotine (Neupro) for Parkinson’s disease. Med Lett...

Ziprasidone (Geodon - Pfizer), a benzisothiazolyl piperazine, has been approved by the FDA for oral treatment of schizophrenia. An intramuscular formulation will probably be available in the near future.

Nabilone (Cesamet - Lilly), a synthetic cannabinoid chemically related to tetrahydrocannabinol (THC), the main active ingredient in marijuana, was recently marketed in the USA for oral treatment of nausea and vomiting associated with cancer chemotherapy. Oral THC itself, known generically as dronabinol (Marinol), is also commercially available as an antiemetic for cancer patients (Medical Letter, 27:97, 1985). Other drugs used for this purpose include metoclopramide (Reglan - Medical Letter, 24:67, 1982), prochlorperazine (Compazine; and others), haloperidol (Haldol; and others), and...
