Q

Some pts may not respond to high dose statins and may require adjunct therapy. Which 3 meds would you consider, in order from first line to last line and why?

A
  1. Ezetimibe is the first non-statin medication that should be considered in most pt scenarios. It is safe and tolerable and has demonstrated modest efficacy when added to moderate-dose statin.
  2. Bile acid sequestrants (BAS) may be considered as second-line therapy for patients in whom ezetimibe is not tolerated.
    (Avoid in patients with triglycerides >300 mg/dl)
  3. PCSK9 Inhibitors may be considered if the goals of therapy have not been achieved on maximally tolerated statin and ezetimibe in higher-risk patients with clinical ASCVD or familial hypercholesterolemia.
    **Given the lack of long-term safety and efficacy data
    not recommended for use in primary prevention pts who do not have familial hypercholesterolemia

a. add aspirin to their regimen
b. increase the dose of the statin
c. temporarily stop the statin and then try a different statin
d. tell them to suck it up

A

C.

The approach to suspected statin intolerance:

  • temporary discontinuation of statin therapy
  • lower dosing
  • re-challenge preferably with 2-3 statins of differing metabolic pathways
  • intermittent (1-3x weekly) dosing of long half-life statins

Q

Case 5: A 48-year-old man with FH and history of 3-vessel coronary artery bypass surgery 7 years ago sees you now for statin intolerance. The maximum dose of statin that he can tolerate is rosuvastatin 10 mg twice a week. On more frequent dosing he developed shoulder, low back, and thigh aching without weakness and a normal CK level. He had similar symptoms on low doses of simvastatin, atorvastatin and pravastatin.

On rosuvastatin 10 mg twice a week, his most recent LDL–C was 168 mg/dL, triglycerides were 138 mg/dL, and HDL–C was 46 mg/dL.

Which of the following statements is the most correct answer?

a. Ezetimibe has been shown to further reduce ASCVD events when added
to statin therapy. He should continue the rosuvastatin and ezetimibe 10 mg should be added.

b. Gemfibrozil has been shown to reduce ASCVD events when used as
monotherapy in men with coronary heart disease. He should continue the
rosuvastatin and gemfibrozil 600 mg twice daily should be added.

c. Bile acid sequestrants have been shown to reduce ASCVD events when
used as monotherapy in men with primary hypercholesterolemia. He
should continue the rosuvastatin and cholestyramine 4 g packet twice
daily should be added.

d. He should discontinue the rosuvastatin and begin lovastatin 40 mg daily.

A

c. Bile acid sequestrants have been shown to reduce ASCVD events when
used as monotherapy in men with primary hypercholesterolemia. He
should continue the rosuvastatin and cholestyramine 4 g packet twice
daily should be added.

In high risk pt’s (hx ASCVD or LDL >190) you would consider tx with non-statin if the maximally tolerated statin therapy has not achieved >50% reduction in LDL-C from baseline by their next visit with you.
Statins work pretty quickly, so you should be seeing changes by the time you recheck their levels.
