Enhancement of Ursodeoxycholic Acid Bioavailability by Cross‐linked Sodium Carboxymethyl Cellulose

The bioavailability of ursodeoxycholic acid from a new formulation based on drug‐loaded cross‐linked sodium carboxymethyl cellulose was studied in man. The plasma levels of ursodeoxycholic acid were determined by gas chromatography‐mass spectrometry after derivatization and sample purification by solid‐phase extraction. Capsules containing the drug/polymer system were prepared and compared with conventional commercial ursodeoxycholic acid capsules after single oral administration using a randomized crossover experimental design.
