title: Evaluation of dosage forms. VI. Studies of commercial oxyphenbutazone tablet dosage forms.
abstract: Dissolution-dialysis studies of commercial tablets of oxyphenbutazone were carried out to establish the applicability of this technique for the in vitro evaluation of oxyphenbutazone dosage form. While disintegration time and dissolution rate studies did not give a true indication of bioavailability, an excellent correlation was obtained between the dialysis rate constant K and the pharmacokinetic parameters AUC and Cmax.
