Dermatologicals: Formulation, Screening Methods, Toxicity Testing, Skin Penetration Enhancement, Bioequivalence, and Regulatory Issues. Contact: Program Division, TECHNOMIC Publishing AG, Missionsstrasse 44, CH-4055 Basel, Switzerland. Te: 061/381 52 26 Fax: 061/381 52 59.

"Methods to determine topical bioequivalence, a topic of major practical importance to the industry, will be discussed as well as strategies to reduce dermal irritancy and sensitization. Also, the development of human tissue engineered models, as well as their usage in industrial pre-clinical safety and efficacy testing after topical application and "real time" exposure will be discussed."
