Dyslipidemia Flashcards
(50 cards)
which station(s) is consider high intensity?
atorvastatin and rosuvastatin
- high intensity means it can lower LDL > 50% from baseline**
what to do if patient has muscle myopathy with statin?
Hold med, wait 2 to 4 weeks, re-challenged at same or lower dose
can re-challenged twice, second re-challenged at lower dose
after 2nd re-challenged –> avoid statin
Can you re-challenged if patient has myopathy with statin?
yes
- you can re-challenged twice*
- 2nd re-challenged at lower dose*
atorvastatin max dose
80 mg
lovastatin max dose
80 mg
pravastatin max dose
80 mg
rosuvastatin max dose
40 mg
- Asian patient - may need to lower dose - exposure are 2x higher in Asian*
simvastatin max dose
40 mg
** do not use 80 mg**
which 3 statins are CYP 3A4 substrates
ASL
atorvastatin
simvastatin
lovastatin
** pravastatin and rosuvastatin have less interaction **
explain amlodipine and statin (ASL) interaction
amlodipine inhibits 3A4
ASL (ator, simv, lova) - substrate of 3A4
amlodipine can increase level of ASL
Max dose:
atorvastatin 10 mg
simvastatin 20 mg
Lovastatin 40 mg
** note: these are also equivalent dose**
G❤PACMAN
- helps you identify?
- each stands for
CYP 3A4 inhibitors (strong)
G - grapefruit
P - protease inhibitor (HIV tx)
A - azole antifungal
C - cyclosporine, cobicstat
M - macrolide (x azithromycin)
A - amiodarone
N - Non DHP CCB
ezetimibe moa
blocks absorption of cholesterol
simvastatin and eGFR
eGFR < 60
** do not exceed simv 20 mg**
ezetimibe + gemfibrozil intxn
increase risk of cholelithiasis
** do not use combo**
explain MOA of PCSK9 maB
- Alirocumab (Praluent)
- Evolocumab (Repatha)
PCSK9 - is an enzyme that breaks down LDL receptors when it binds to LDL receptors
LDL receptors clears circulating LDL
** PCSK9 maB (inhibitors) prevent PCSK9 from binding to LDL receptors
How long can Praluent and Repatha be store at room temp
30 days
Bile acid sequestrant MOA
- Colesevelam (Welchol)
- Cholestyramine (Prevalite)
- Colestipol (Colestid)
define sequestrant?
Sequestrant - binds to or absorp
Bile acid sequestrants bind to bile acid, prevents its reabsorption
Body has to use more cholesterol to make bile acid
Welchol (colesevelam) indications
cholesterol
DIABETES
* also approved for glycemic control in type 2 DM
* decrease AC1 ~ 0.5%
bile acid sequestrants
* colesevelam (Welchol)
* Cholestyramine (Prevalite)
* Colestipol (Colestid)
Clinical: when not to use
DO NOT USE when Triglyceride is > 300 mg/dL
Bile acid sequestrants increase TG ~ 5%
How to take bile acid sequestrants?
Interactions with other drugs
Mix with water and take with FOOD
Take all other drugs at least 4 hours before or 4 hours after bile acid sequestrants
Fibrates MOA
- Fenofibrate
- Fenofibric Acid
- Gemfibrozil
PPAR-alpha agonist
upregulate expression of lipoprotein lipase activity (increase activity)
Lipoprotein lipase - breaks down VLDL
This decreases TG, but can increase LDL in the setting of very high TG
Catabolism define
the breakdown of complex molecule in body
Fibrates
Clinical notes
decrease TG ~ 50%
can increase LDL in the setting of very high TG
Gemfibrozil SHOULD NOT be use with ezetimibe or statin
Fibrates can affect ___ and ___
Sulfonylureas
* fibrates can increase hypoglycemic affect
Warfarin
