medications exam 2 Flashcards
ezetimbibe (Zetia)
Cholesterol Absorption Inhibitor
inhibits the intetinal absorption of cholesterol; lowers LDL, raises HDL
cholesterol absorption inhibitor
side effects: infrequent, but may include headache and mild GI distress
cholesterol absorption inhibitor
nursing implication: may be combined with a statin- ezetimibe/simvastin; monitor AST and ALT
cholesterol absorption inhibitor
cholestyramine/ colestipol/ colesevelam
bile acid sequestrants
binds with bile acids in intestine, forming insoluble complex and excreted in feces. binding results in removal of LDL and cholesterol
bile acid sequestrants
side effects: unpleasant quality to taste, GI disturbances (indegestion, constipation, bloating)
bile acid sequestrants
nursing implications: interferes with the absorption of some drugs (Coumadin, thiazides, thyroid hormones, beta adrenergic blockers, digoxin, diuretcs, and some antibiotics). take before meals with plenty of fluids. mix powder with liquid throughly. take other medications 1 hour before, or 4 hours after, this medication
bile acid sequestrants
fenofibrate/ gemfibrozil
fibric acid derivatives
accelerates the elimination of VLDLs. increases production of apoproteins A-I and A-II. most effective in lowering triglycerides. also, increase in HDL- no effect on LDL
fibric acid derivatives
side effects: GI irritability (nausea, diarrhea). raises liver enzymes. may raise effects of antihyperglycemic drugs
fibric acid derivatives
nursing implications: should be used with caution when used with statins: raises risk of rhabdomyolysis, may increase risk of bleeding when used with warfarin, take with a meal
fibric acid derivatives
niacin, nicotinic acid
niacin
water soluble B vitamin that lowers LDL and triglyceride levels by interfering with their synthesis
niacin
side effects: severe flushing & pruritus in upper torso and face, GI complaints (nausea, vomiting, dyspepsia, and diarrhea), orthostatic hypotension, can raise homocysteine levels
niacin
nursing implications: instruct patient that flushing will occur within 20-30 minutes of taking drug and lasting 40-60 minutes/ after two weeks the SE should diminish/ ASA or NSAOD taken 30 minutes prior to administration may eliminate flushing
niacin
lovastatin/ pravastatin/ simvastin/ fluvastin/ atorvastin/ rosuvastatin/ pitavastatin
HMG-CoA reductase inhibitors
inhibits the synthesis of cholesterol in the liver by blocking hydroxymethylglutaryl coenzyme A reductase/ increase in hepatic LDL receptors; therefore, can remove more LDL from the blood. also, lowers VLDL and triglycerides. a small increase in HDL
HMG-CoA reductase inhibitors
side effects: liver damage and myopathy that can prgress to rhabdomyolysis (breakdown of skeletal muscle) also, may have rash and GI disturbances
HMG-CoA reductase inhibitors
nursing implications: monitor liver enzymes aspartate aminotransferase (AST), alanine aminotransferase (ALT), creatine kinase enzymes are assessed if symptoms of myopathy occur. take with evening meal or at night; avoid grapefruit juice
HMG-CoA reductase inhibitors
ranolazine
sodium current inhibitor
exact mechanism of action is unknown/ to treat chronic angina in patients who have not achieved adequate control with other antianginal meds
sodium current inhibitor
side effects: dizziness, headache, constipation, nausea/ prolongs QT interval; therefore, should be used by patients who have not responded to other antianginal drugs
sodium current inhibitor
nursing implications: monitor for prolonged QT interval
sodium current inhibitor
captopril/ enalapril
angiotensin converting enzyme inhibitor
prevents conversion of angiotensin I to angiotensin II and decreases in preload and afterload and thus decreases the workload of the heart/ decreases endothelial dysfunction/ useful in HF, HTN, diabetes, and chronic kidney disease
angiotensin converting enzyme inhibitor
side effects: hyperkalemia, hypotension
angiotensin converting enzyme inhibitor
nursing implications: monitor BP, monitor potassium level
angiotensin converting enzyme inhibitor
diltiazem/ verapamil
calcium channel blockers
amlodipine/ felodipine/ nifedipine/ nicardipine
calcium channel blockers
decreases myocardial contractility and heart rate, lowers myocardial oxygen demand/ coronary vasodilation and raises myocardial oxygen supply. used to manage Prinzmetal’s angina
diltiazem/verapamil (calcium channel blockers)
systemic vasodilation with decreased SVR and lowered myocardial workload
amlodipine/ felodipine/ nifedipine/ nicardipine (calcium channel blockers)
bradycardia or high degree of AV block, especially if used with a beta blocker. potentiates the action of digoxine by increasing serum digoxin levels during the first week of therapy. can precipitate HF in patients with compromised LV function–particularly if verapamil or diltiazem is used with a beta blocker
calcium channel blocker
