ASA MOA
- MOA: acetylation & irreversible inactivation of platelet COX-1
- Normal Activity: COX-1 –> TXA2 (promotes clotting)
- ASA Activity: inactivates COX-1, blocks thrombus formation, prolongs bleeding time
- ASA targets COX-1»>COX-2; low doses of ASA ok b/c mainly inhibits COX-1; high doses not ok b/c inhibits both COX-1 and COX-2
- Normal Activity: COX-2 –> prostacyclin PGI2 = inhibits platelet aggregation & causes vasodilation
P2Y12 inhibitor MOA
- MOA: prevents ADP from binding to P2Y12; selectively inhibits ADP-induced PLT aggregation, no direct effecr on TXA2
- Normal Activity: ADP initially binds to P2Y12 (activates it), the active P2Y12 is coupled w/ Gi, Gi inhibits conversion of ADP to cAMP, thus decreasing cAMP; decr cAMP increases Ca++ which causes contraction & coagulation
- P2Y12 inhbitor Activity: prevents ADP from activating P2Y12
list BB cardioselective/Beta1-selective drugs

list BB nonselective drugs
Propranolol, Carvedilol, Labetalol
if drug is beta & alpha blocker, it is also nonselective (targets B1 & B2)
list BB beta/alpha blocker drugs
Labetalol, Carvedilol
Targets B1, B2, and alpha-1
Nitrate MOA
- MOA: nitroglycerin converts to nitric oxide (NO), NO then activates the enzyme guanylyl cyclase, which converts GTP to cGMP, causing relaxation
- direct relaxant effect on vascular smooth muscles;
- dilation of coronary vessels= improves oxygen supply to the myocardium
- dilation of peripheral veins, and in higher doses peripheral arteries= reduces preload and afterload, and thereby lowers myocardial oxygen consumption
DHP CCB MOA
- Suffix: -dipine
- MOA: inhibits influx of Ca++ across blood vessels (only works on blood vessels)
- SE: reflex tachycardia, peripheral edema (dose-related), gingival hyperplasia
- Extra: use amlodipine if CCB is needed in HF; incr risk of angina/MI in pts w/ obstructive coronary disease (specifically immediate-release)
- MOA: Ca++ contracts, so blocking calcium from entering arteries prevents contraction/vasoconstriction, leading to vasodilation (decr BP); more potent vasodilators than NonDHP; decr afterload
- Clinical use: works w/ angina b/c reduces oxygen demand in the heart
- SE: peripheral edema is dose-related; vasodilation leads to reflex tachycardia (amlodipine does not have relflex tachycardia)
- Extra: risk of angina/MI increased due to reflex tachycardia
nonDHP CCB MOA
- Drugs: diltiazem ER, verapamil ER (phenylalkylamine)
- MOA: inhibits influx of Ca++ across blood vessels and heart (smooth and cardiac muscle); negative inotropic effects
- SE: bradycardia, systolic HF, constipation
- MOA: extracellular Ca++ triggers cardiac & vascular smooth muscles to contract, nonDHPs work on cardiac (heart) and smooth (arteries) muscles so less contraction occurs; HR and BP decreased; has ionotropic effects= slows HR and weakens heart’s contraction; antiarrhythmic (blocking of cardiac)
- Clinical use: works w/ angina b/c reduces oxygen demand in the heart
- SE: bradycardia b/c MOA is to slow HR
