The studies of survival and the life span of mice and the toxin in LD50 have shown that 4-
aminopyridine (4-AP) at doses of 1, 2 and 5 mg/kg has a therapeutic effect on type C
botulinic intoxication. Maximum protective effect is observed when 4-AP at a dose of 2 mg/kg
is injected twice daily. Therefore, 4-AP, enhancing the transmitter release into cholinergic
synapses, weakens the toxic effect of botulinic toxin.
