High blood pressure -- and by extension, heart disease -- is the leading cause of death among Americans. Fortunately, there are a number of safe and effective blood pressure medications that can vastly reduce a patient's risk for the many grave consequences of hypertension.

At the bottom of this page, we group the most common blood pressure medications by type. We also provide links to articles that clearly explain the effect each drug has on the body, its possible side effects, and any dangerous interactions the patient should be aware of before filling a prescription.


Naturally, with a condition as serious as high blood pressure, it is important to work closely with your doctor -- but it is equally important to be knowledgeable about all of your treatment options and consequences.


ACE, or angiotensin converting enzyme, inhibitors block the formation of a hormone that causes blood vessels to narrow or constrict.

  • Benazepril (Lotensin)
  • Enalapril (Vasotec)
  • Fosinopril (Monopril)
  • Moexipril (Univasc)
  • Quinapril (Accupril)
  • Ramipril (Altace)
  • Trandolapril (Mavik)


Alpha-blockers relax certain muscles in the body that can constrict or tighten blood vessels. Relaxing these muscles can improve blood flow and lower blood pressure.

  • Doxazosin (Cardura)
  • Terazosin (Hytrin)

Beta Blockers By reducing nerve impulses to certain parts of the body, beta-blockers reduce the body's need for oxygen-rich blood and, ultimately, the heart's workload.

  • Atenolol (Tenormin)
  • Betaxolol (Kerlone)
  • Metoprolol (Lopressor or Toprol)
  • Propranolol (Inderal)
  • Timolol Maleate (Blocadren)

Calcium Channel Blockers

Calcium channel blockers slow the absorption of calcium into the muscle cells, which widens blood vessels and leads to greater oxygen delivery to the heart.

  • Amlodipine (Norvasc)
  • Diltiazem (Cardizem, Dilacor, or Tiazac)
  • Felodipine (Plendil)
  • Isradipine (DynaCirc)
  • Nifedipine (Adalat, Nifedical, or Procardia)
  • Verapamil (Calan, Isoptin, Verelan)


Diuretics, sometimes called "water pills," mainly affect the kidneys and the amount of sodium in your body. With less sodium in the body, there is less water in the blood, which reduces the amount of pressure on the arterial walls.

  • Furosemide (Lasix)
  • Hydrochlorothiazide (Esidrix, HydroDIURIL, Microzide, or Oretic)
  • Spironolactone (Aldactone)
  • Triamterene (Dyrenium)


Vasodilators actually widen, or dilate, the blood vessels by relaxing the muscle in the vessel walls. This allows for an easier flow of blood and lower blood pressure.

  • Captopril (Capoten)
  • Clonidine (Catapres)
  • Irbesartan (Avapro)
  • Losartan (Cozaar)
  • Nitroglycerin (Nitrogard, Nitroglyn, Nitrolingual, Nitrong, NitroQuick, or Nitrostat)
  • Perindopril (Aceon)
  • Prazosin (Minipress)
  • Telmisartan (Micardis)
  • Valsartan (Diovan)
