A long-term study comparing lacidipine and nifedipine SR in hypertensive patients: safety data

Abstract

The clinical safety of lacidipine, a new dihydropyridine calcium antagonist, has been assessed in a long-term, comparative study in hypertensive patients. Slow-release (SR) nifedipine was used for comparison. The type and incidence of adverse events seen with both drugs are characteristic of the dihydropyridine class of drugs and were mainly due to pharmacologically induced vasodilation, but lacidipine caused a significantly lower incidence of ankle edema than nifedipine SR. There were no unexpected adverse events during the treatment. The addition of atenolol 50 mg once daily did not increase the frequency of adverse events. Therefore, lacidipine can be considered a safe antihypertensive drug, which can be used as a suitable agent for first-line treatment of hypertension.
