Q

Bile acid binding agents (BABA) drugs include

A

Cholestyramine
Colestipol
Cholesevalam

13
Q

Mechanism of action of BABA drugs

A

BABA binds on bile acids and let passes them in feces - decrease in bile acids
And bile acids are produced from cholesterol - Cholesterol will be used to produce bile acids - so there will be decrease of Cholesterol in blood
