Cards

Term
Statins
Definition

HMG-CoA reductase inhibitors

-statin

pleiotropic effects

Term
Decreased Protein Prenylation
Definition
isoprenoids decrease protein prenylation: leads to reducing arterial intimal thickening, preventing restenosis, increasing iNOS, decrease IL-6 and CRP, decrease platelet aggregation, inhibit PAI --> decrease thrombus formation
Term
half-life & efficacy
Definition

atorvastatin and rosuvastatin have longest half life

 

all inhibit HMG-CoA to same extent except pravastatin (only 50%)

Term
LDL, HDL, TG
Definition

statins reduce LDL

niacin (<exercise) increases HDL

fibric acid decreases TG

 

problem: niacin causes histamine release

Term
ezetimibe
Definition

blocks cholesterol uptake in intestine

 

can be paired with statin, but does not work

Term
fenofibric acid
Definition

treat TG

 

can be combine with atorvastatin = AtorvaFen

 

do NOT combine with gemfibrozil

Term
Statin effects
Definition

-LDL: greatest by atorva- and rosuva- but little clinical significance

+HDL: 1%

-TG: 10%

Term
ADR
Definition

DO NOT use during pregnancy

low incidence of ADRs

very safe drugs

some hepatotoxicity and rhabdomyotoxicity

 

do not take with 3A4 inhibitors (-navirs)

Term
Hepatotoxicity
Definition

dose related

mostly asymptomatic

Term
rhabdomyotoxicity
Definition

-myalgia: soreness

-myopathy: myalgia + high CK

-myolysis: myopathy + myoglobinemia + myoglobinuria

Term
Statins
Definition

-LDL>>-TG>>+HDL

dual acting drugs

single isomers

lipophilic (except prava, rosuva)

atorva and rosuva most potent

cave 3a4 inhibitors and gemfibrozil
