Abstract
A method is provided to parenterally administering an analgesic (i.e., fentanyl) to a patient in the presence of a cannabinoid receptor agonist. This has been found to unexpectedly result in an almost order of magnitude increase in the therapeutic index over that of administering fentanyl alone. The respective amounts of the cannabinoid receptor agonist and fentanyl are selected to achieve the therapeutic index of the analgesic is greater than about 1000. While the method of the present invention contemplates administering the drug by all the medication routes other than orally, the preferred route is via inhalation.
