Nifedipine

Uses

Nifedipine is used in the treatment of angina (heart-related chest pain), hypertension (high blood pressure), arrhythmia, heart attack, hypertensive emergency, subarachnoid hemorrhage, stroke, and anal fissure.

How it Works

How Nifedipine works Nifedipine is a calcium channel blocker. In cases of high blood pressure, it normalizes blood pressure by relaxing the blood vessels, which reduces the pressure on them and improves blood flow throughout the body. The increased blood flow further relaxes the heart muscles by decreasing the workload on the heart. Additionally, it enhances oxygen delivery in the body, thereby preventing heart-related chest pain.

Side Effects

Common side effects of Nifedipine include dizziness, fatigue, flushing (a sense of warmth in the face, ears, neck, and trunk), headache, and peripheral edema.
