The established drug names have also been changed, in order to reinforce individual potencies and prevent medication errors. The new name to replace botulinum toxin type A is OnabotulinumtoxinA (marketed as Botox and Botox Cosmetic). The name that replaces to botulinum toxin type B is RimabotulinumtoxinB (marketed as Myobloc). The FDA has also approved another botulinum toxin product in this class, AbobotulinumtoxinA (marketed as Dysport), and this product also includes boxed warnings. 

Surprisingly perhaps, given its extreme toxicity, botulinum toxin was introduced into medical practice in 1983 to treat patients with squint. Since then, its use has been expanded to include other disorders of muscle control suffered by patients with cerebral palsy or after a severe stroke where the brain cannot control the muscles, which may remain permanently contracted. Tiny amounts of the toxin are injected into the affected muscle, which then becomes paralyzed and, so, relaxed. There are several forms of the toxin that are now marketed as "Botox 7 (type A toxin) and Myobloc (type B toxin). More recently, Botox has been used in "cosmetic77 medicine as a way of reducing lines and wrinkles in the face due to aging.
