materials and methods liposomes were prepared by thin film method using soya lecithin and cholesterol. physicochemical characteristics of the liposomes such as, particle size, drug encapsulation efficiency were determined. also, drug release and in vitro skin permeability through rat skin were evaluated using franz diffusion cells. results the results showed that the maximum drug encapsulation ...
متن کاملLiposomes- and ethosomes-associated distamycins: a comparative study.
The present article describes a comparative study of the performances of liposomes and ethosomes as specialized delivery systems for distamycin A (DA) and two of its derivatives. Liposomes and ethosomes were prepared by classical methods, extruded through polycarbonate filters, and characterized in terms of dimensions, morphology, and encapsulation efficiency. It was found that DA was associate...
