Abstract

Topically applied compositions for transdermal administration of efficacious paid relief medication are described. The compositions contain several physiologically active components which act synergistically to attack pain-causing aspects of an injury or disorder while simultaneously blocking the immediate transmission and sensation of the pain. As the source of the pain is progressively diminished, the patient is spared the sensation of current and transient pain. Thus the compositions provide the patient with relief of both systemic and perceived pain. The compositions include medically effective amounts of a vasodilator, a non-steroidal anti-inflammatory drug, a membrane stabilizer, and a seratogenic reuptake inhibitor, and a medically acceptable carrier into which the foregoing are incorporated. Medically effective amounts of a topical anesthetic and/or a steroid anti-inflammatory drug are also advantageously included. A method of relief of a patient's pain which comprises topical administration to the patient of such compositions is also described.
