ABSTRACT:
The invention is directed to methods and pharmaceutical compositions for the topical administration of opioid analgesic drugs such as morphine. In particular, the invention relates to topical administration of an opioid analgesic agent, e.g., morphine sulfate, in admixture with a skin- or mucosal-specific penetration enhancer, to produce a localized analgesic effect in inflamed or non-inflamed skin or mucosal tissue, and without a transdermal or transmucosal migration of opioid agent, e.g., into the systemic circulation.
