Bellergamin possesses cholinolytic ganglioplegic and sedative action and has
a regulation effect on the functions of vegetative nervous system. Alkaloids of
Atropa belladonna, exerting a manifested peripheral and a certain central M-cholinolytic
action, suppress the spasms of smooth muscles of gastrointestinal and urogenital
tract, inhibit the secretion of exocrine glands, at therapeutic doses manifest a
sedative effect. Ergotamine exerts adrenolytic effect, weakly inhibits metabolism,
exerts a manifested antiserotonine action, has a manifested uterotonic and vasospastic
effect. Phenobarbital exerts a central sedative effect, suppresses insomnia, has
a manifested anticonvulsive action.
