Answer: False

Which of the following medications have no primary effect on heart rate, but can lower blood pressure
Sergeeva-Olga [200]

Calcium channel blocker

These medications lower blood pressure and treat other conditions such as chest pain and an irregular heartbeat.

<h3>What are Calcium channel blocker ?</h3>

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.

  • The medications may also be prescribed to relieve chest pain (angina) and control an irregular heartbeat.

  • Calcium channel blockers are also called calcium antagonists.
