if the creatine kinase level becomes elevated during statin therapy, what should happen?
the drug should be immediately discontinued.
What is the drug that’s mechanism of action interferes with HMG-CoA reductase, the critical enzyme in the biosynthesis of cholesterol.
Statins
What is the drug that’s mechanism of action decreases both VLDL and LDL levels
Niacin.
What is the drugs that’s mechanism of action blocks the absorption of cholesterol from the small intestine
Ezetimibe
What is the drug that’s mechanism of action binds bile acids, thus increasing the excretion of cholesterol in the stool
Bile acid sequestrants
Rare but serious adverse effects of statins
Severe myopathy and rhabdomyolisis
Patients taking statins could benefit from enhancing their diet with foods rich in CoQ10- like pork- why?
Statins reduce coQ10 synthesis
Lipid lowering drugs can deplete or diminish the absorption of what?
Fat soluble vitamins and folic acid
Gemfibrozil is contraindicated in patients with what
Chronic kidney disease
What drug is the only drug in a class called cholesterol absorption inhibitors and can block absorption of cholesterol which can cause the body to respond by creating more cholesterol?
Ezetimibe (Zetia)
Gemfibrozil (fibric acid derivative) is indicated for the treatment of what conditions
Hyper triglycerides and hypercholesterolemia
(It lowers VLDL with an increase in HDL)
NOT effective for lowering LDL
A patient has a triglyceride level of 450 mg/dL. Which drug should the nurse anticipate being prescribed for this patient
Fibric acid
Cholestyramine (Questran) can bind to other drugs. When should it be taken with a patient who also takes digoxin
2hours before or 4 hours after
If statins are having minimal impact and aren’t tolerated well by the patient, what drug would be the next choice
Gemfibrozil (lopid)
A patient is prescribed Gemfibrozil (Lopid). For which reason should the nurse expect the medication to be discontinued for this patient
Elevated low density lipoproteins (LDL)
Cholestyramine is contraindicated for what
Biliary obstruction
Triglycerides should be less than what number to be in normal range
Less than 150
What is the drug Atorvastatin (Lipitor)
Statin.
Side effects- myalgia, arthralagia, rhabdomyolisis (leads to renal failure!) elevated hepatic enzymes.
What do B-complex Vitam B do for lipid disorders and name the drug given
Decreases the VLDL into LDL, reduced triglycerides.
Niacin is what’s given
Side effects- flushing, nausea, diarrhea, hepatotoxicity, gout
What do Fibric Acid Drugs do for lipid disorders
Activate the enzyme lipoprotein lipase, lower LDL, triglycerides and most effective lipid drug to increase HDL
Fenofibrate (Lofibra)
-administered with meals to decrease GI upset
What do the kidney excrete that helps regulate bp
Renin enzyme
What do kidneys excrete that stimulates red blood cell production
Erythropoietin hormone
If a drug is bound to plasma proteins will it pass through the glomerulus and enter the filtrate or continue circulating in the blood.
Continue circulating. It’s too big
Diuretic drugs and therapy for kidney failure
Diuretics: Loop/ thiazide/ potassium sparing.
Used for: HTN, AKI & CKD, heart failure, pulmonary edema.
Nurse teaching: monitor weight, HR, BP
