title: Cardiovascular effects of Azadirachta indica extract.
abstract: A crude extract of the leaves of Azadirachta indica was studied for its effects on the cardiovascular system of anesthetized guinea pigs and rabbits. These effects include profound hypotension and a minimal negative chronotropic effect, which increased at higher doses. In one rabbit, 200 mg of extract/kg decreased the heart rate from 280 to 150 beats/min. The extract also exhibited a weak antiarrhythmic activity in rabbits against ouabain-induced dysrhythmia.
