(German Commission E.)Berberine is bactericidal, amoebici- dal and trypanocidal. Berberine is an- tidiarrhoeal, asitentersinto the cytosol or binds to the cell membrane and inhibits the catalytic unit of andenylate cyclase. It is active in vitro and in animals against cholera.Berberine stimulates bile secretion and shows sedative, hypotensive, anti- convulsant and uterine stimulant activity in animals. Alkaloid bermarine is also strongly antibacterial. It has been shown to increase white blood cell and platelet counts in animals with iatro- genic leukocytopaenia.Berberine, berbamine and jatror- rhizine are hypotensive and sedative.Many of the alkaloids are antineo- plastic.The alkaloid berbamine (50 mg three times daily for 1-4 weeks) helped reverse leukopaenia induced by benzene, cancer chemotherapy or radiotherapy in a clinical study. (Francis Brinker.)Berberine, when combined with pyrimethamine, was more effective than combinations with other antibiotics in treating chloroquine-resistant malaria. (Sharon M. Herr.)
