How Diltiazem Works

Diltiazem works by relaxing the blood vessels and increasing the blood flow to the heart, which helps lower blood pressure and improve blood flow to the heart muscle. It does this by blocking calcium channels in the heart and blood vessels, which reduces the contraction of the heart and dilates the blood vessels. This mechanism of action helps to reduce the workload of the heart and improve oxygen supply to the heart muscle.

Benefits of Diltiazem

– Effectively lowers blood pressure and helps manage hypertension.
– Relieves chest pain associated with angina by improving blood flow to the heart.
– Can be used to treat certain types of arrhythmias or irregular heartbeats.
– May help prevent migraines in some individuals.

Side Effects of Diltiazem

While Diltiazem is generally well-tolerated, some individuals may experience side effects such as:
