Antihyperlipidemic Flashcards
main goal of lipid-lowering agents or antihyperlipidemic meds
prevent CADs
prevent atherosclerosis
accumulation of lipids causing the hardening and narrowing of the walls of the arteries
atherosclerosis
primary cause of dyslipidaemia
excessive alcohol intake
diabetes
liver disease
nephrotic syndrome
corticosteroid treatment
in the liver _________ and _____________ are transported in the blood by lipoprotein particles
cholesterol (produced by liver) and triglycerides
functions of HDL and LDL
HDL - high density lipoproteins removes excess cholesterol in the blood and take it back to the liver
LDL - low density lipoproteins transport cholesterol throughout the body cells. High LDL lvls results in plaque build-up in the arteries
is made up of fat, cholesterol and calcium which overtime will hardens and narrows the walls of the arteries limiting blood flow and oxygen supply to the body organs
plaque
antihyperlipidaemic meds
HMG-CoA reductase inhibitors (statins)
Antiplatelets
ezetimibe
fibrates
HMG-CoA reductase inhibitor pharmacodynamics
inhibits HMG-CoA reductase - which is an enzyme responsible for synthesising cholesterol in the liver and increasing LDL receptors
Statins helps reduce total cholesterol lvls, LDLs and less extent triglycerides. Also reduce inflammation and have plaque stabilisation benefits
Adverse effects of statins
myalgia and myopathy - muscle pain, tenderness and weakness
myoglobinuria - acute renal failure
statin contraindications
liver disease and alcoholic person
NOT COMPATIBLE with pregnant person due to congenital abnormalities and decrease synthesis of cholesterol will affect foetal development
statins drug interactions
erythromycin - erythromycin increases simvastatin exposure causing RHABDOMYOLYSIS (damaging muscle tissues which releases its harmful proteins (myoglobin) and electrolytes in the blood harming the heart and kidneys causing permanent movement disability and death.
HMG-CoA inhibitor meds
simvastatin
atorvastatin
pravastatin
other hyperlipidemic meds
ezetimibe - prevents intestinal absorption of cholesterol. Use with statin to further reduce CADs and high risk of diabetes
fibrates - decreases triglyceride serum minimum effect on LDLs. CAUTION for GALL STONES (hard deposits of bile in the gall bladder)
