Abstract:
A transdermal topical anesthetic formulation, which can be used to ameliorate or inhibit pain, has been developed. In the preferred embodiment, the topical anesthetic is a local anesthetic such as lidocaine, most preferably lidocaine free-base in a gel, and the dosage of the local anesthetic is effective in the painful area or immediately adjacent areas, to ameliorate or eliminate the pain. High concentration of local anesthetic in solution in the carrier is used to drive rapid release and uptake of the drug. Relief is typically obtained for a period of several hours.
