My office is investigating claims of injury because of this recalled product.
Sibutramine is a centrally-acting serotonin-norepinephrine reuptake inhibitor. Serotonin and norepinephrine reuptake inhibitors (SNRIs) are a type of antidepressant medication that increases the levels of both serotonin and norepinephrine by inhibiting their reabsorption (reuptake) into cells in the brain. Although the precise mechanism of action isn't clear, it's thought that these higher levels enhance neurotransmission — the sending of nerve impulses — and so improve and elevate mood. Medications in this group of antidepressants are sometimes called dual reuptake inhibitors.
Sibutramine was originally launched and marketed by Knoll Pharmaceuticals and was most recently manufactured and marketed by Abbott Laboratories before its withdrawal from the market.
