Oral medication has been the mainstay of therapy; however, the use of topical formulation for chronic pain can reduce serious systemic side effects caused by oral medications. Topical administration of medication via patches, gels, creams, ointments, and solutions can provide local anesthesia and bypass major organ system. Lidocaine is an amide-type local anesthetic agent stabilizing the neuronal membranes by inhibiting the ionic fluxes required for initiation and conduction of impulses. Capsaicin is a selective agonist for TRPV1 receptor expressed in afferent neuronal C fibers and Ad fibers resulting in loss of receptor functionality causing impaired local nociception.Diclofenac works via inhibition of prostaglandin synthesis by blocking COX-1 and COX-2.
