Toxta 100U is a peripheral muscle relaxant that contains purified botulinum toxin type A combined with hemagglutinin and sodium chloride (as an excipient). It works by blocking nerve impulse transmission to muscles, leading to muscle relaxation and a reduction in the appearance of facial wrinkles. Toxta is supplied as a lyophilized white powder which is reconstituted into a solution before use, and is packaged in glass vials containing 100 units of the active ingredient.
