Lupanine (100-300 mg/kg for i.p.; 175-700 mg/kg for p.o.) is much less toxic in one single injection in EOPS male Swiss mice (20-22 g) and Hartley guinea-pigs (400-500 g)^[1].
Lupanine (1-7.5 mg/kg; i.v.) is more efficient than Sparteine for antagonizing secondary reflex hypertension in carotid occlusion and hypotension resulting from the stimulation of the pneumogastric nerve in both the cat and the dog^[1].
Lupanine has an inhibitory action on nicotinic type hypertension produced by injection of Acetylcholine (500 p.g/kg i.v.) in the Atropine-treated dog^[1].
