What are the metabolites of diclofenac?
The metabolites include 4'-hydroxy-, 5-hydroxy-, 3'-hydroxy-, 4',5-dihydroxy- and 3'-hydroxy-4'-methoxy diclofenac. The major diclofenac metabolite, 4'hydroxy-diclofenac, has very weak pharmacologic activity. The formation of 4'-hydroxy diclofenac is primarily mediated by CPY2C9. Both diclofenac and its oxidative metabolites undergo glucuronidation or sulfation followed by biliary excretion. Acylglucuronidation mediated by UGT2B7 and oxidation mediated by CPY2C8 may also play a role in diclofenac metabolism. CYP3A4 is responsible for the formation of minor metabolites, 5-hydroxy and 3'-hydroxy- diclofenac.

How do NSAIDs work?
As previously stated, most NSAIDs are administered enterally and their pH profile facilitates absorption via the stomach, and the large surface area of the small intestine produces a major absorptive site for orally administered NSAIDs. Most of the NSAIDs are rapidly and completely absorbed from the gastrointestinal (GI) tract, with peak concentrations occurring within 1 to 4 hr. The presence of food tends to delay absorption without affecting peak concentration. 10 Most NSAIDs are not available in parenteral forms in the United States. Only three have been approved for parenteral administration: ketorolac, propacetamol, and ibuprofen. Parenteral administration may have the advantage of decreased direct local toxicity in the GI tract, but parenteral ketorolac tromethamine, for example, does not decrease the risk of adverse events associated with COX-1 inhibition. Topical NSAIDs possess the advantage of providing local action without systemic adverse effects. These medications, such as diclofenac epolamine transdermal patch (Flector®) and diclofenac sodium gel (Voltaren®), are formulated to traverse the skin to reach the adjacent joints and muscles and exert therapeutic activity, and may offer some advantage in terms of decreased adverse events.

Does lidocaine block sodium channels?
Topical and transdermal medications can be a useful adjunct because of their ability to disrupt hypersensitive signaling from the myofascial focus to the spinal cord and higher centers. Lidocaine in various topical formulations (cream, transdermal patch) is believed to block sodium channels that may increase pain signaling. Lidocaine 5% patches were tested in a 1-month, open-label trial in 27 patients with myofascial pain. 44 By the end of the trial, several key parameters, including average pain intensity, mood, sleep, walking ability, and enjoyment of life, were significantly improved. These results have been replicated in a larger randomized, placebo-controlled trial as well as in a trial noting that lidocaine patches demonstrated benefit similar to bupivacaine injections, with improved tolerability. 45,46
