Mechanism of Action
Possibly by deforming the channel, inhibiting ion-control gating mechanisms, and/or interfering with the release of calcium from the sarcoplasmic reticulum, diltiazem, like verapamil, inhibits the influx of extracellular calcium across both the myocardial and vascular smooth muscle cell membranes. The resultant inhibition of the contractile processes of the myocardial smooth muscle cells leads to dilation of the coronary and systemic arteries and improved oxygen delivery to the myocardial tissue.
- Diltiazem is well absorbed from the gastrointestinal tract but undergoes substantial hepatic first-pass effect.
- Diltiazem is metabolized by and acts as an inhibitor of the CYP3A4 enzyme.
