The FDA has approved the nitrofuran antiprotozoal drug nifurtimox (Lampit – Bayer) for treatment of Chagas disease (American trypanosomiasis) in children who weigh ≥2.5 kg. Nifurtimox was previously available in the US only through a CDC-sponsored Investigational New Drug (IND) program.

Fluticasone furoate nasal spray (Veramyst - GSK) is now available for once-daily treatment of seasonal and perennial allergic rhinitis in adults and children ≥2 years old. It is similar to fluticasone propionate nasal spray (Flonase, and others), which is now available generically.

Levocetirizine (Xyzal - UCB/Sanofi-aventis), the active enantiomer of the second-generation H₁-antihistamine cetirizine (Zyrtec), has been approved by the FDA for treatment of seasonal and perennial allergic rhinitis (SAR and PAR) and chronic idiopathic urticaria in adults and children 6 years of age and older. Cetirizine has been approved by the FDA for over-the-counter use and may also become available generically in the US. Levocetirizine has been available in Europe since 2001.

Recently published results of a large, carefully conducted retrospective study indicated that use of the antibiotic azithromycin (Zithromax, and others) may increase the risk of cardiovascular death, especially in patients with a high baseline risk of cardiovascular disease.1 One possible mechanism is prolongation of the QT interval, which is known to occur rarely with azithromycin and more frequently with the other macrolide antibiotics erythromycin (Erythrocin, and others) and clarithromycin (Biaxin, and others).Among the patients who received 347,795 prescriptions for azithromycin, there...

Cefuroxime axetil (Ceftin - Glaxo), an oral form of the second-generation parenteral cephalosporin cefuroxime (Zinacef), was recently marketed in the USA. Previously available oral cephalosporins are the first-generation drugs cephalexin (Keflex; and others), cephradine (Anspor; and others) and cefadroxil (Duricef; and others), and the second-generation cefaclor (Ceclor); second-generation cephalosporins have more activity against gram-negative bacteria.

Perindopril, the tenth angiotensin converting enzyme (ACE) inhibitor to be marketed in the USA, and telmisartan and eprosartan, the fifth and sixth angiotensin receptor blockers, have recently become available for treatment of hypertension.

The FDA has approved the marketing of buprenorphine in sublingual tablets (Reckitt Benckiser) both alone (Subutex) and with naloxone (Suboxone) for treatment of opioid dependence. Previously available only for parenteral use in treatment of pain (Buprenex, and others), it offers an alternative to methadone (Dolophine, and others), which is now often abused (New York Times, February 9, 2003; page 1). As a schedule III narcotic, buprenorphine will be subject to fewer prescribing restrictions than a schedule II drug such as methadone (MJ Kreek and FJ Vocci, J Subst Abuse Treat 2002;...
