drug mechanisms and indications (midterm 1) Flashcards
Angiotensin-converting enzyme (ACE aka kininase) inhibitor; suppresses RAA system and simultaneously inhibits bradykinin degradation
lisinopril moa
Indication for lisinopril
HTN
CHF
ACUTE MI
VALSARTAN
Selective antagonist of Angiotensin II receptor
INDICATION FOR VALSARTAN
HTN
CHF
POST MI
amlodipine moa
Inhibits trans membrane Ca++ current into vascular smooth muscle»_space; cardiac muscle
indication for amlodipine
HTN
CAD
Antagonizes peripheral alpha-1 adrenergic receptors
TERAZOSIN MOA
indication for terazosin
HTN
BPH
- Selective competitive antagonism of β1 receptors reducing systolic BP and CO via negative inotropic (beats soft) and chronotropic (beats slow)effects
- Central acting inhibition of sympathetic outflow
- Suppression of renin activity
metoprolol
indication for metoprolol
HTN
angina pectoris
POST MI
Inhibits reabsorption of NaCl at proximal/distal convoluted tubule & loop of Henle
Anti-HTN: High Ceiling/Loop Diuretic (Ca2+ and K+ depleting)
FUROSEMIDE MOA
indication of furosemide
HTN*,
Acute Pulomo-nary Edema (respiratory distress),
Hyper-calcemia
Inhibits reabsoprtion of NaCl at distal convoluted tubule
Anti-HTN: Thiazide Diuretic (Ca2+ sparing)
hctz moa
indication for hctz
HTN, Peripheral Edema, CHF, Osteo-porosis
Antagonizes aldosterone receptors in distal convoluted tubule resulting in sodium/water loss and potassium retention
Anti-HTN: Potassium sparing diuretics (drugs that do not promote the secretion of potassium into the urine)
spironolactone
spironolactone indication
HTN, CHF, Hyperaldosteronism, Hypo-kalemia
Stimulates central and spinal alpha-2 adrenergic receptors (pre-synaptic and post-junctional)
Anti-HTN: Central-Acting Alpha Agonist
-Analgesic
clonidine
clonidine indication
htn
severe cancer related pain
Directly dilates peripheral vessels via hyperpolarization of vascular smooth muscle which thus inhibits Ca2+ influx (depolarization)
moa of hydralazine
indication of hydralazine
htn
chf
hypertensive crisis
