FDA APPROVES GSK'S WELLBUTRIN XL FOR SAD

A A

GlaxoSmithKline's (GSK) Wellbutrin XL has been approved to be the first drug for treating patients with a history of seasonal affective disorder (SAD), the FDA announced. Wellbutrin XL (bupropion HCl extended-release tablets) was previously approved for treatment of major depressive disorder.

The approval, however, comes with requirement for a black box warning on the drug's labeling concerning the increased risk of suicidal thoughts and behavior in pediatric patients treated with antidepressant medications. This stems from an FDA announcement in early 2004 that cited the possible risk of suicide with several antidepressants -- GSK's Wellbutrin and Paxil (paroxetine), Eli Lilly's Prozac (fluoxetine), Pfizer's Zoloft (sertraline), Solvay's Luvox (fluvoxamine), Forest Laboratories' Celexa (citalopram) and Lexapro (escitalopram), Wyeth's Effexor (venlafaxine), Bristol-Myers Squibb's Serzone (nefazodone) and Organon's Remeron (mirtazapine).
