Tolerability and efficacy of colestipol hydrochloride for accelerated elimination of teriflunomide.

The administration of colestipol HCl for 15 days was sufficient to reduce plasma teriflunomide concentrations by greater than 96%. Although colestipol HCl did not completely eliminate teriflunomide with the same effectiveness as cholestyramine, it may offer an alternative method for accelerated elimination of teriflunomide with potentially improved tolerability and more favorable dosing and administration options.
