How do calcium channel blockers work for hypertension?

Calcium channel blockers are medications used to lower blood pressure. They work by preventing calcium from entering the cells of the heart and arteries. Calcium causes the heart and arteries to squeeze (contract) more strongly. By blocking calcium, calcium channel blockers allow blood vessels to relax and open.

What are dihydropyridine calcium channel blockers used for?

Dihydropyridine calcium channel blockers are drugs used to treat high blood pressure and severe angina (chest pain caused by lack of oxygen to the heart muscle). Dihydropyridines are one of the different types of calcium channel blockers; they predominately act on blood vessels with less effect on the heart.

What is a natural calcium-channel blocker?

Magnesium is an example of a nutrient that acts as a natural CCB. Research has shown that higher levels of magnesium block the movement of calcium. In animal studies, magnesium supplementation seemed to be most effective in the young with elevated blood pressure, before they developed hypertension.

Are there any antihypertensives that block calcium channels?

There are sufficient clinical data to demonstrate that the dihydropyridine calcium channel blocker (DHP CCB) class of antihypertensives such as amlodipine and nifedipine, although effective in reducing systemic hypertension, lack activity in reducing proteinuria or attenuating sympathetic activity.

When to start an antihypertensive medication for Stage 1 HTN?

In patients with stage 1 HTN, recommendations are to start antihypertensive medications if the patient has a 10-year ASCVD risk of 10% or higher with a target of BP less than 130/80 to prevent patients from cardiovascular events.

What should my BP be with Stage 2 HTN?

Recommendations are for all patients with stage 2 HTN to start antihypertensive medications to lower BP to a target lower than 130/80 even if the 10-year ASCVD risk is less than 10%. In patients with chronic kidney disease, the target BP is 130/80
