Used primarily in the treatment of hypertension and chronic stable angina, this compound functions as a calcium channel blocker, specifically targeting L-type calcium channels in vascular smooth muscle. It promotes vasodilation, reducing peripheral vascular resistance and lowering blood pressure. Due to its enantiomeric specificity, the (S)-enantiomer exhibits significantly greater potency in calcium channel blockade compared to the (R)-form, allowing for lower dosing and reduced side effects. It is commonly prescribed as a once-daily oral medication, offering sustained release and consistent blood levels over 24 hours. Its long half-life contributes to improved patient compliance and steady control of cardiovascular symptoms.
