Types of High Blood Pressure Medicines

High Blood Pressure Medication
  • ACE Inhibitors
  • Beta Blockers
  • Calcium Channel Blockers
  • Peripherally Acting Alpha-Adrenergic Blockers
  • Angiotension II Antagonists
  • Vasodilators
  • Centrally-Acting Alpha Adrenergics
  • Renin Inhibitors
  • Combination Medicines
  • Diuretics (sometimes called “water pills”)

ACE Inhibitors

Angiotensin Converting Enzyme (ACE) Inhibitors prevent the formation of a hormone called angiotensin II, which normally causes blood vessels to narrow. The ACE Inhibitors cause the vessels to relax and blood pressure goes down. Sometimes cause an irritating cough.

Beta Blockers

Beta-blockers reduce nerve impulses to the heart and blood vessels. This makes the heart beat slower and with less force. Blood pressure drops and the heart works less hard. Beta-blockers Can cause cool hands and feet, poor sleep, tiredness, and impotence in some users.

Calcium Channel Blockers (CCBs)

CCBs keep calcium from entering the muscle cells of the heart and blood vessels. This causes the blood vessels to relax and pressure goes down. Sometimes cause dizziness, facial flushing, swollen ankles, and constipation.

Angiotension II Antagonists

Angiotensin antagonists shield blood vessels from angiotensin II. As a result, the vessels become wider and blood pressure goes down. sometimes cause dizziness


Vasodilators directly open blood vessels by relaxing the muscle in the vessel walls, causing the blood pressure to go down.

Centrally-Acting Alpha Adrenergics

Centrally-Acting Alpha Adrenergics lowers blood pressure by decreasing certain chemicals in the blood, which relax blood vessels, and thus heart beat slowly and easily. Other clinical uses include treatment of alcohol withdrawal, pediatric pre-anesthetic, for pediatric postoperative pain control, treatment of migraine headaches, nicotine addiction, menopausal flushing, attention-deficit disorder, and pediatric panic and anxiety disorders.  Side effects of Centrally-Acting Alpha Adrenergics can be Dizziness,dry mouth,upset stomach, drowsiness or tiredness. Avoid Centrally-acting alpha adrenergics, If

  • Pregnant or nursing women should talk to their doctor before using these medications.
  • Have heart disease, recent heart attack, or kidney disease should talk to their doctor before using these medications.
  • Drinking alcohol may make side effects worse.

Renin Inhibitors

Renin inhibitors produce vasodilation by inhibiting the activity of renin, which is responsible for stimulating angiotensin II formation. Renin is a proteolytic enzyme that is released by the kidneys in response to sympathetic activation, hypotension, and decreased sodium delivery to the distal renal tubule

Diuretics (sometimes called “water pills”)

Diuretics are sometimes called “water pills” because they work in the kidney and flush excess water and sodium from the body. Can cause gout attacks in a small number of users, or can make gout worse if you already have gout. Impotence develops in some users.
