Summary

Ketoconazole may inhibit the bile salt export pump, which cholic acid therapy depends on for hepatic bile salt excretion. Accumulation of conjugated bile salts in hepatocytes can cause liver injury.

What this interaction means in plain words

Cholic acid and Ketoconazole 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; Ketoconazole belongs to Anti Fungals.

Evidence level: Moderate

Why it happens

Inhibition of the bile salt efflux pump (BSEP) reduces hepatic bile salt elimination.

What to do

Avoid the combination where possible; if it is necessary, monitor serum transaminases and bilirubin regularly and stop cholic acid if liver injury develops.
