How Amlodipine 5 mg Works in the Body
Amlodipine 5 mg relaxes the smooth muscles in blood vessel walls. By blocking calcium from entering these cells, it widens arteries, which lowers blood pressure and improves blood flow to the heart.
This action reduces the heart's workload and helps prevent angina episodes. Because the drug has a long half-life, it provides steady control with once-daily dosing, which supports consistent blood pressure management.
