This webinar will discuss USP General Chapters <724> and <1724> and will present the equipment, most common conditions, and challenges for the evaluation of the in vitro performance tests of drug products applied to the skin. Dosage forms that can be applied to the skin include ointments, pastes, creams, lotions, gels, foams, and transdermal systems.
