Amlodipine besylate is a calcium antagonist or a calcium channel blocker. The drug is a type of antihypertensive because it relaxes blood vessels, resulting in lower blood pressure. Lower blood pressure helps reduce the risk of heart attacks, kidney problems and strokes. The drug is prescribed to patients who have heart conditions such as angina and high blood pressure. Amlodipine besylate is marketed under the brand name Norvasc, and it comes in tablet form.

Prescribing physicians should know what medications you take before they prescribe Amlodipine besylate as some combinations of medicine may require special types of tests and dosage considerations or may result in Amlodipine besylate not being prescribed at all.
