Drugs for Lipid Disorders - Kruse Flashcards
VLDL
transports TGs from liver to adipose and muscle tissue - made in the liver
LDL
transports cholesterol to extrahepatic tissue - made in circulation from VLDL
HDL
promotes transport of cholestrol from extrahepatic tissue to the liver for excretion
factors the increase LDL
cholesterol, saturated and trans fats
factors the increase TGs
total fat, alcohol, excess calories
statin with best oral absorption
fluvastatin
T1/2 of most statins
1-3 h
T1/2: atorvastatin
14h
T1/2: rosuvastatin
19h
Statins that use CYP34A
lovastatub, simvastatin, and atorvastatin
statins that use CYP2C9
fluvastatin and rouvastatin
statins that use CYP450
pitavastatin (limited)
potency of statins
atorva- = rousva- > sima- > pitava- = lova- = prava- > fluva-
only lipid lowering agent that significatlyreguce Lp(a)
niacin
most effective agent to increase HDL levels
niacin
MOA: niacin
inhibition of lipolysis of TGs in adipose tissue; reduces fibrinogen and increases tissue plasminogen activator to help reduces edothelial cell dysfunction
AE: statins
- elevated serum aminotransferase
- increased creatine kinase
- rhabdomyolysis
- myopathy
- increases warfarin levels
CI: statins
- pregnancy, lactation
- liver dz
- skeletal mm myopathy
- concomitant use of other drugs that utilize CYP450 (phenytoin, griseofulvin)
AE: niacin
- skin flushing
- pruitis, rash, dry skin/mm
- ancanthosis nigricans (esp in DM)
- hyperglycemia in DM
CI: niacin
- hepatic dz
- active peptic ulcer
T1/2: gemfibrozil
1.5h
T1/2: fenofibrate
20h
MOA: fibrates
angonist ligand for PPAR(apha) which regulates expression of genes involved in lipoprotein structure and function
Therapeutic uses: fibrates
- tx increased VLDL hyperTGemia
- tx hyperTGemia resulting from anti-viral tx
- dysbetalipoproteinemia
