🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
This medicine works by blocking calcium channels in the smooth muscle cells of blood vessels. Calcium is needed for these muscles to contract. By blocking calcium entry, the medicine causes the muscles to relax, which widens the blood vessels (vasodilation). This lowers blood pressure and improves blood flow to the heart, reducing the frequency and severity of angina attacks.
