DRUG MECHANISMS and indications (final) Flashcards
PDE-5 Inhibitor; sustains the vasodilatory effects of nitric oxide-dependent synthesis of cGMP
sildenafil moa
indications for sildenafil
ED and pulmonary arterial HTN
Inhibits vitamin K-dependent coagulation factor synthesis (II, VII, IX, X, proteins C and S)
coumadin moa
indication for coumadin
anticoagulation
Binds to Antithrombin-III and accelerates its activity, inhibiting thrombin and Factor-Xa
enoxaparin moa
indication for enoxaparin
post op DVT prophylaxis, unstable angina
Prodrug: metabolized to active metabolite by the CYP450 enzyme CYP2C19
Irreversible inhibition of platelet ADP receptors which normally trigger platelet activation and aggregation via downstream activation of the GP llb/llla complex
clopidogrel moa
indication for clopidogrel
acute coronary syndrome, thrombotic event prophylaxis
- Fab Fragment: a chimeric human-murine mAB
- Binds to the GP llb/llla receptor of human platelets and inhibits platelets aggregation
- Binds to the vitronectin (αvβ3) receptor on platelets and vessel wall endothelial and smooth muscle cells
moa for abciximab
indication for abciximab
An adjunct to percutaneous coronary intervention (PCI) for the prevention of cardiac ischemic complications, Unstable Angina
Competitively inhibits HMG-CoA Reductase which is responsible for an early, rate-limiting step in cholesterol biosynthesis
Increases hepatic LDL receptors, enhancing catabolism
atorvastatin moa
atorvastatin indication
hyperlipidemia/cvd prevention
Stimulates nuclear receptor PPAR which modulates transcription of insulin sensitive genes in liver, muscle and adipose tissue
Enhances HDL production; inhibits triglyceride synthesis and stimulates catabolism of triglyceride-rich lipoproteins
fenofibrate moa
indications for fenofibrate
hypertriglyceridemia and hypercholesterolemia
Inhibits lipolysis in adipose tissue, resulting in reduced hepatic VLDL synthesis and production of LDLs in the plasma
nicotinic acid moa
