Levamisole

Levamisole is the levorotatory isomer of tetramisole, a synthetic imidazothiazole anthelmintic that has been in veterinary and human medicine for decades. It works by selectively agonizing nicotinic acetylcholine receptors at the parasite’s neuromuscular junction, causing spastic paralysis and rapid expulsion. We supply levamisole base and hydrochloride in high-purity grade (≥99% HPLC), suitable for formulation in oral, injectable, and topical dosage forms.
