Summary for Patent: 5,016,652

Title: Method and apparatus for aiding in the reduction of incidence of tobacco smoking
Abstract:A dermally applicable patch adapted for application to the skin of the user to enable a transdermal administration to the bloodstream of a user. The patch comprises an outer layer which is impermeable to the passage of nicotine and an inner layer which may operate as a rate controlling membrane to allow the passage of nicotine into the bloodstream of a user. An outer layer and an inner layer form a nicotine receiving area for receiving the nicotine to thereby allow the same to pass through the inner layer. In a preferred embodiment, the patch is highly effective in reducing the incidence of tobacco smoking by allowing transdermal nicotine migration into the bloodstream of a user at a rate sufficient to correspond to the nicotine level in the blood achieved by smoking.
