3.3 Classes of Medications-Part 1

Watch this video for a quick introduction to this topic, understanding your medication.

 

There are different classes of high blood pressure medications. Each class contains many different drugs. They are listed below. The generic name is listed first, followed by the brand name. Some medications interact with food, supplements, vitamins, herbs, alcohol, and other medications. This can increase or decrease the effect of the medication. Always talk to your doctor about other medications or supplements you may be taking.

DIURETICS: They decrease the volume of blood in your body by getting rid of excess water and sodium. This helps to decrease blood pressure. There are three types: thiazide diuretics, loop diuretics, and potassium-sparing diuretics. They are also called water-pills.

THIAZIDE DIURETICS: They increase the amount of sodium and water that your body gets rid of.

  • Chlorothiazide (Diuril ®)
  • Chlorthalidone (Hygroton ®)
  • Hydrochlorothiazide (Esidrix ®, Microzide ®, Hydrodiruril ®)
  • Indapamide (Lozol ®)
  • Metolazone (Mykrox ®, Zaroxolyn ®)

LOOP DIURETICS: They block your kidneys from taking in extra sodium and chloride.

  • Bumetanide (Bumex ®)
  • Ethacrynic acid (Edecrin ®
  • Furosemide (Lasix ®)
  • Torsemide (Demadex ®)

POTASSIUM-SPARING DIURETICS: They increase the amount of water and sodium that your body gets rid of. But, it reduces the amount of potassium that your body gets rid of. So, you get rid of sodium, but you keep potassium.

  • Amiloride (Midamor ®)
  • Eplerenone (Inspra ®)
  • Spironolactone (Aldactone ®)
  • Triamterene (Dyrenium ®)

Food-Drug Interactions:

  • Some diuretics cause loss of the minerals potassium, calcium, and magnesium from the body.
  • Potassium-Sparing diuretics can increase the amount of potassium in your body. Avoid eating large amounts of foods high in potassium.
    • This includes bananas, oranges, green leafy vegetables, and salt substitutes that contain potassium.
  • Licorice may reduce the effects of diuretic drugs such as hydrochlorothiazide (Hydrodiruril ®) and spironolactone (Aldactone ®).

 

Food-Drug Interactions: ACE inhibitors can increase the amount of potassium in your body. Avoid eating large amounts of foods high in potassium, such as bananas, oranges, green leafy vegetables, and salt substitutes that contain potassium.

ANGIOTENSIN II RECEPTOR BLOCKERS: They are like ACE inhibitors. They allow the blood vessels to widen, and they decrease the amount of sodium and water that is kept in the body. This lowers blood pressure.

  • Azilsartan medoxomil (Edarbi ®)
  • Candesartan (Atacand®)
  • Eprosartan (Teveten®)
  • Irbesaratan (Avapro®)
  • Losartan (Cozaar®)

RENIN INHIBITORS: Renin is an enzyme that is produced in the kidneys and it starts a process that increases blood pressure. Renin inhibitors stop this process.
