24
Q

List low intensity statins

A

simvastatin 10
pravastatin 10-20
lovastatin 20

25
Q

What % do low intensity statins lower cholesterol by?

A

<30%

26
Q

Which cholesterol lowering drugs cause liver damage (4)

A

Niacin
fibrates
exetimibe
potentially statins

27
Q

Statin MOA

A

inhibit the enzyme HMG-CoA reductase which prevents the conversion of HMG-CoA to mevalonate. this is the rate-limiting step in cholesterol synthesis

28
Q

define myalgias

A

muscle soreness and tenderness

29
Q

define myopathy

A

muscle weakness +/- CPK elevations

30
Q

define myositis

A

muscle inflammation

31
Q

define rhabdomyolysis

A

muscle symptoms with very high CPK (>10000) + muscle protein in the urine (myoglobinuria) which leads to acute renal failure

32
Q

gemfibrozil + statin DDI

A

myalgias

33
Q

Which statins need taken in the evening

A

simvastatin

lovastatin

34
Q

which statins are CI with strong cyp3a4 inhibitors

A

simvastatin

lovastatin

35
Q

statins + niacin DDI

A

myopathies

36
Q

Max dose of simvastatin when used with CCB

A

10mg/day

37
Q

Max dose of simvastatin when used with amiodarone, smlodipine

A

20 mg/day

38
Q

ezitimibe MOA

A

inhibits absorption of cholesterol in the small intestine

39
Q

PCSK9 inhibitors MOA

A

bind to proprotein convertase subtilisin kexin type 9. PSCK9 inhibitors inhibit the binding of PCSK9 to LDL receptors thus increase the number of LDL receptors available to clear LDL

40
Q

List PCSK9i

A

Alirocumab

Evolucumab

41
Q

Bile Acid sequestrants MOA

A

bind bile acids in the intestines, forming a complex that is excreted in the feces

42
Q

List BAS

A

Cholestyramine
colesevelam
colestipol

43
Q

Which BAS can a pregnant women use

A

cholesevelam

44
Q

Fibrates MOA

A

peroxisome proliferator receptor alpha (PPARa) activators, which upregulate the expression of apolipoprotein c2 and apolipoprotein A1. apoc-2 increases lipoprotein lipase activity leading to increased catbolism of BLDL particles. this will decrease TG significally

45
Q

List fibrates

A

fenofibrate

gemfibrozil

46
Q

CI for fibrates

A

severe liver disease including primary biliary cirrhosis

gallbladder disease

47
Q

Niacin MOA

A

decreases rate of hepatic synthesis of VLDL (decreases TG) and LDL

48
Q

What is niacin also known as?

A

nicotinic acid

vitamin B3

49
Q

Major SE of niacin

A

flushing

50
Q

How to reduce flushing in niacin

A

ASA 325 30-60 min before dose

51
Q

When are fish oil indicated

A

TG > 500

52
Q

List fish oils

A

omega-3 acid ethyl esters (lovaza)
-has EPA and DHA
icosapent ethyl (Vascepa)
-has EOA

53
Q

fish oil effect on LDL

A

Lovaza can inc by 44%

no increase seen with vascepa

54
Q

Lomitapide MOA

A

binds to and inhibits microsomal TG transer protein (MTP) which prevents the assembly of apoB containing lipoproteins

55
Q

Mipomersen MOA

A

oligonucleotide inhibitor of apoB synthesis

56
Q

Indication for lomitapide and mipomersen

A

Homozygous familial hypercholesterolemia
