Hyperlipidemia Flashcards
What is the MOA of statins?
Statins are HMG-CoA reductase inhibitors, preventing the synthesis of cholesterol by HMG-CoA
What are 3 examples of statins?
Atorvastatin
Simvastatin
Fluvastatin
~ the statins
What is the clinical indication for statins?
Lowering LDL-C in all types of hyperlipidemias
Reduce risk of coronary events and mortality in patients with ischemic heart disease
When should statins be given?
In the evening as de novo synthesis of cholesterol is the predominant pathway at night
What are the adverse effects associated with the use of statins?
- Abnormalities in liver function
- Myopathy & rhabdomyolysis
What group of individuals are statins contraindicated in?
Pregnant, nursing mothers
Children & teenagers(Statins affect neurodevelopment of children & fetus)
Why are statins commonly given for hyperlipidemia?
Statins are effective in reducing LDL-C levels in all types of hyperlipidemias
What is the MOA of PCSK9 inhibitors?
They inhibit PCSK9, preventing the degradation of cell-surface LDL receptors.This increases LDL uptake by the cells, reducing cirulating LDL.
PCSK9 degrades cell-surface LDL receptors
What are 2 examples of PCSK9 inhibitors?
Evolocumab
Alirocumab
What is the route of administration of evolocumab?
via injection
What is evolocumab indicated in?
- Lowering LDL-C levels in familial hypercholesterolaemias (type IIa), especially those intolerant to statins
- Patients with significant atherosclerotic CVD even after being on maximally-tolerated statin therapy
What are the adverse effects associated with the use of PCSK9 inhibitors?
- Hypersensitivity
- Injection site inflammation
- Sinusitis & nasopharyngitis
Fibrates activate ________, resulting in increased activity of ________.More triglycerides are uptaken by the cells, reducing plasma triglyceride levels
Fibrates activate PPAR-alpha, resulting in increased activity of lipoprotein lipase.More triglycerides are uptaken by the cells, reducing plasma triglyceride levels
What are 2 examples of fibrates?
Gemfibrozil
Fenofibrate
w
What are gemfibrozil/fenofibrate indicated in?
Hypertriglyceridemias with VLDL elevation
