Beta Blockers and Diuretics

  1. What is the mechanism for beta-blockers?
    blocks the effects of adrenaline on your body's beta receptors
  2. What are the Beta 1-receptors responsible for?
    heart rate and strength of your heart beat
  3. What are Beta 2-receptors responsible for?
    function of smooth muscles in blood vessels, bronchi, GI tract, and genitourinary tract
  4. Where are the adrenal glands located and what do they secrete?
    they are located on top of the kidneys; they secrete epinephrine and norepinephrine
  5. What is epinephrine?
    a hormone that increases heart rate and force of heart contractions, thus increasing blood pressure
  6. what is norepinephrine?
    a hormone has strong vasoconstrictive effects, thus increasing blood pressure
  7. what are some other names for beta blockers?
    beta-adrenergic blocking agents; beta-blocking agents
  8. What are the indications for beta blockers?
    Hypertension; Angina: Helps prevent additional heart attacks in heart; attack patients; Corrects irregular heartbeat; Prevents migraine; headaches; Treat tremors
  9. What do beta-blockers reduce?
    heart rate and blood pressure
  10. are all beta blockers receptor selective?
    no some are non-selective (affecting both beta-1 and beta-2 sites
  11. What are some possible side effects of beta blockers?
    Slow heart-rate (bradycardia); Fatigue; Dizziness; Depression; Shortness of breath; Nightmares; increases skin sensitivity to sunlight
  12. Why should diabetics be careful while taking beta blockers?
    may cause blood glucose to rise, can increase glucose intolerance, can mask symptoms of hypoglycemia
  13. Why can beta blockers possibly mask hypoglycemic symptoms?
    it prevents stimulating "fight or flight" responses of the body thereby inhibiting gluconeogenesis
  14. What is the patient education for beta blockers?
    take with food to increase absorption; may increase skin sensitivity to sunlight
  15. What is the mechanism for diuretics?
    cause kidneys to remove more sodium and water from the body and relaxes the blood vessel wall resulting in lower blood pressure
  16. What class of drug is triamterene/HCTZ? What is/are the brand name(s) for it?
    diuretic; maxzide and dyazide
  17. What can triamterene be used for to treat?
    fluid retention (edema) in people with: congestive heart failure, cirrhosis of the lever, nephrotic syndrome
  18. What makes triamterene different from other diuretics?
    K+ sparing, prevents body from absorbing too much salt, keeps potassium levels from getting too low, used to keep K+ in body
  19. What class of drug is hydrochlorothiazide? What is its brand name?
    diuretic; HydroDIURIL
  20. What class of drug is furosemide? What is its brand name?
    diuretic; Lasix
  21. What class of drug is spironolactone? What is its brand name?
    diuretic; aldactone
