Abstract
A combined chemo-thermo therapy technique in which a pharmaceutical agent, such as a lipolysis cream, is topically applied to a localized skin surface overlying a problem region to be treated. This surface is then subjected to an air stream whose temperature alternates periodically from a high peak level to a lower base level in a pulsatory heat energy wave pattern. Because heat transfer takes place under the skin in the intervals between successive peaks, the temperature of the problem region is significantly raised, but that on the skin surface remains at a tolerable level. As a consequence, the absorption of the agent and its diffusion throughout the tissues of the heated problem region is accelerated and its interaction therewith is promoted to enhance the effectiveness of the treatment.
