Burke is developing proprietary products for improving the delivery of drugs to the skin and epidermis. Dermatologic diseases are typically expressed in the upper dermis and epidermal layers of the skin. The stratum corneum is the rate controlling barrier to effective drug delivery (Figure 1).
Burke has developed a novel dermabrasion device for pretreatment of the skin to disrupt the stratum corneum. This device is utilized prior to application of topical products to improve their absorption.
Burke is also developing improved topical (creams, gels, ointments, patches) formulations combining permeation enhancers for optimized target delivery to the epidermis for treatment of selective dermatological diseases. Burke is developing novel products for intradermal injection in needle-free and standard needle-based injection devices. These products will be a first line treatment for verrucae and other localized skin diseases.
