一种突触后肌肉松弛剂，可抑制肌浆网储存的 Ca2+ 离子释放；拮抗兰尼碱受体。

Oxodipine, a dihydropyridine-type calcium antagonist, inhibited KCl-induced aortic contraction in rabbits and reduced cardiac force in less potent rat ventricular test-paper contractions. In rat cultured neonatal ventricular myocytes, Oxodipine reduced L-type Ca currents (I) with an IC of 0.24 μM, and against T-type Ca currents (I) with an IC of 0.41 μM. Oxodipine causes constipation in mice and gingival hyperplasia in dogs.
