Diltiazem HCl (33286-22-5) is a non-dihydropyridine-type blocker of L-type Ca²⁺ channels^1,2.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.
