Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase-1 (COX-1) and cyclooxygenase-2 (COX-2), thereby reducing prostaglandin synthesis, which mediates inflammation, pain, and fever.
Solaraze (diclofenac sodium) is a nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase (COX-1 and COX-2) enzymes, reducing prostaglandin synthesis, which mediates inflammation and pain. In actinic keratosis, it may also induce apoptosis and decrease keratinocyte proliferation.
50 mg intramuscularly every 6 hours as needed for pain; maximum 150 mg per day.
Apply 0.5 mL (1 unit dose) topically to actinic keratoses twice daily for 2 to 4 weeks, then 1 week off, repeat for a total of 3 treatment cycles.

2-4 hours (terminal) in adults; prolonged in elderly (up to 6-8 hours) and hepatic impairment (up to 12 hours).
Following topical application, the terminal elimination half-life of diclofenac from plasma is approximately 12 hours (range 8-15 hours). This reflects the slow absorption and distribution from the skin depot, with clinical relevance for twice-daily dosing.
Renal: ~50% as unchanged drug and metabolites (glucuronide conjugates); Biliary/fecal: ~40% as metabolites; <5% unchanged in feces.
Solaraze (diclofenac sodium 3% gel) is primarily eliminated via hepatic metabolism followed by renal excretion of metabolites. Approximately 65% of a dose is excreted in urine as conjugated metabolites, with less than 1% as unchanged drug. About 35% is eliminated in feces via biliary excretion of metabolites.
