Bioactive formulations with sugar-derived surfactants: a new approach for photoprotection and controlled release of promethazine.

ABSTRACT

Skin deep A bioactive formulation for dermal delivery of antihistamines is obtained by using the original properties of catanionic associations towards self-assembly in water. The drug, which participates in its own transport, is preserved from photodegradation when solubilised in the bioactive formulation. The drug release through the skin is also delayed.
