Summary
Mifepristone inhibits the bile salt export pump, which can cause conjugated bile salts to accumulate in hepatocytes. With cholic acid this may worsen liver injury or cholestasis.
What this interaction means in plain words
Cholic acid and Mifepristone can interact in a way that may be serious. Using them together is sometimes necessary, but it needs a deliberate decision by the prescriber, a plan for monitoring, and clear advice on the warning signs to watch for.
Cholic acid belongs to Gastrointestinal Tract; Mifepristone belongs to Endocrine.
Why it happens
Inhibition of the bile salt export pump (BSEP) by mifepristone reduces biliary excretion of bile acids.
What to do
Avoid concomitant use where possible. If necessary, monitor serum transaminases and bilirubin regularly and stop cholic acid if liver injury develops.
