Establishment of Biopredictive Dissolution and Bioequivalence Safe Space Using the Physiologically Based Biopharmaceutics Modeling for Tacrolimus Extended-Release Capsules

Publication: AAPS PharmSciTech
Software: GastroPlus®
Division: PBPK

A slight variation in in vivo exposure for tacrolimus extended-release (ER) capsules, which have a narrow therapeutic index (NTI), significantly affects the pharmacodynamics of the drug. Generic drug bioequivalence (BE) standards are stricter, necessitating accurate assessment of the rate and extent of drug release.
