Prolonged Drug Release from a Novel Gel Formulation Composed of DrugContaining Catanionic Vesicles and Oppositely Charged Hydrophobically ModifiedPolymer, Intended for e.g. Transdermal Applications

摘要

Gel formation was observed in mixtures of catanionicvesicles and oppositely charged, hydrophobicallymodified polymers. Drug release from these novel gelscould be substantially prolonged.
