On this episode, I discuss the pharmacology of cholestyramine.



Cholestyramine was originally developed as an agent to manage cholesterol, but has fallen out of favor for some of the more effective agents like statins.



Cholestyramine is notorious for binding drug interactions. It can reduce concentrations of drugs like amiodarone, digoxin, oral contraceptives, immunosuppressive and many more!



In patients with chronic diarrhea, cholestyramine is occasionally used off label to help manage symptoms because it tends to have constipating effects.
