Mechanism
Isradipine, a calcium channel antagonist, produces its effects by binding to the alpha-1 subunit of the L-type Ca2+ channels. This binding reduces Ca2+ flux through the channel, thereby altering the plateau phase of the cardiac action potential and decreasing contraction in cardiac and vascular smooth muscle cells.
Indications
Hypertension
Pharmacokinetics
Metabolism
Metabolized by CYP3A4.
