Overview of commonly prescribed blood pressure medications

Brief Introduction to the Different Classes of Blood Pressure Medications

There are several classes of medications commonly prescribed to treat high blood pressure, also known as hypertension. These medications work in different ways to lower blood pressure and maintain it within a healthy range.

Some of the most commonly prescribed classes of blood pressure medications include:

  • Diuretics: These medications help the kidneys remove excess water and salt from the body, thus reducing blood volume and lowering blood pressure.
  • Calcium channel blockers: Calan belongs to this class of medications. Calcium channel blockers work by blocking the entry of calcium into the cells of the heart and blood vessels, which helps relax the blood vessels and improve blood flow, thereby reducing blood pressure.
  • Angiotensin-converting enzyme (ACE) inhibitors: These medications prevent the production of angiotensin II, a hormone that constricts blood vessels. By doing so, ACE inhibitors promote vasodilation and lower blood pressure.
  • Angiotensin II receptor blockers (ARBs): ARBs block the action of angiotensin II, similar to ACE inhibitors, leading to vasodilation and decreased blood pressure.
  • Beta-blockers: These medications reduce the workload on the heart by blocking the effects of adrenaline, thereby slowing down heart rate and reducing blood pressure.
