ACE inhibitors: angiotensin converting enzyme inhibitors.
They are antihypertensive drugs that reduce the synthesis of angiotensin II, which causes vasocontriction of blood vessels, which helps control blood pressure. The ACE inhibitors prevent the hormone being produced, from an inactive form angiotensin I- thus reduces vasoconstriction and lowers blood pressure.
SIDE EFFECTS: dry cough, dizziness, abnormal heart rhythm, a reduction in kidney function.
Calcium channel blockers
They are antihypertensive drugs that block calcium channels in the muscle cells in artery linings. The calcium must pass through these channels into the muscle cells for the muscles to contract. If the calcium doesn't enter the cell contraction of the muscle is prevented, so blood vessels do not contrict and…
