decreases major coronary events but NO significant decrease in mortality |
|
|
Term
AE and drug intrxns of fenofibrate |
|
Definition
AE:

|
|
|
Term
AE and CI of nicotinic acids |
|
Definition
AE:
-flushing MC!
-may cause glucose intolerance and increase uric acid

Term
drug intrxns nicotinic acids |

Definition
decreased effect of oral hypoglycemics
may inhibit uricosuric effects of sulfinphyrazone and probenecid (inhibits uric acid elimination)
