Diltiazem HCl (33286-22-5) is a non-dihydropyridine-type blocker of L-type Ca2+ channels1,2.Reduces Ca2+ oscillations in subcellular compartments in vascular smooth muscle cells3. Also blocks P-type Ca2+ channels in freshly dissociated rat cerebellar Purkinje neurons4. Clinically useful antihypertensive agent5. Cell permeable.
