Spectrofluorimetric analysis and buccal absorption of medifoxamine.
Medifoxamine is a new investigational antidepressant drug. Its buccal absorption at pH 5-9, which can be considered as an in-vivo model of passive drug transfer through a lipid membrane, was studied in six normal, healthy volunteers to predict its pharmacokinetic profile in man. Maximum absorption of medifoxamine occurred at pH 8, which is close to its pKa (8.5).
