Liposome Dermatics Griesbach Conference

In a multi-disciplinary approach the book deals with liposome dermatics fromthe chemist's, pharmacist's, biologist's as well as clinician's point of view. It features the production of liposomes, appropriate raw materials, encapsulation of active ingredients, possible incorporation into vehicles such as gels, assessment of stability, fate of liposomes and active ingredients exposed to animaland human skin both in vitro and in vivo, activity of topical liposome preparations in normal and inflamed skin in animal and man as well as efficacy in skin diseases in man. Other aspects covered comprise the ecological and juridic area. The scope being theoretical and practical at a time, the book provides a sound basis for future developments to meet the needs of patients suffering from so far recalcitrant skin diseases.
