Comp16-Anti-Hyperten
Competency 16
Question | Answer |
---|---|
Anti-Hypertensives | drugs used to lower blood pressure through various mechanisms of action. |
Beta Blockers | Lower blood pressure by lowering cardiac output. |
examples of beta blockers | Tenormin(atenolol), Inderal(propranolol), Betopic(Betaxolol) |
Alpha Blockers | Lower blood pressure by lowering cardiac output. |
Examples of Alpha Blockers | Cardura(Doxazosin), Hytrin(terazosin), Prazosin(minipress) |
Diuretics | Decrease blood pressure by decreasing blood volume |
Thiazides | Increase the excretion of Sodium and Chloride |
Examples of Thiazides | Diuril(Chlorothiazide), HCTZ(hydrochlorothiazide) |
Loop | Generate a larger elimination response than that of the thiazides. |
Examples of Loop | Lasix(furosemide), Edecrin(ethacrynic acid) |
Potassium Sparing | Weaker diuretic often used in conjunction with other diurectics. |
Examples of Potassium sparing | Dyazide(hydrochlorothiazide & triamterene combination) |
Carbonic Anhydrase Inhibitors | Interfere with the action of carbonic anhydrase in the kidney and also the eye |
Examples of carbonic anhydrase inhibitors | Diamox(acetazolamide) Trusopt(dorzolamide) |
Osmotic | Their action solely through osmosis |
Angiotensin-Converting Enzyme inhibitors(ACE Inhibitors) | relax the blood vessels and increases excretion of sodium and water |
Examples of ACE Inhibitors | Capoten(captopril), Vasotec(enalapril), Altace(ramipril) |
Calcium Channel Blockers | Block the movement of calcium ions cell membranes and cause vasodilation |
Examples of Calcium Channel Blockers | Procardia(nifedipine), Isoptin(verapamil),Norvasc(amlodipine) |
Centrally Acting Alpha-Adrenergic Blockers | Used in patients with moderate to sever hypertension . example Catapres (clonidine) |
