The present invention is directed to a method and system for delivering a drug into the systemic circulation. The method comprises establishing a drug depot in a patient's skin and/or sub-skin tissues by applying a transdermal drug delivery system on the patients skin, for a predetermined time so that a drug depot is formed in said user's skin and/or sub-skin tissues. A heating source is placed proximate to the skin area to rapidly release a bolus of the drug from the depot into the systemic circulation when there is a need to rapidly increase the drug's concentrations in the systemic circulation.

Why it's free to use
- Filed June 10, 2002. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended June 10, 2022.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by June 10, 2024.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
