Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Inhibition of prostaglandin synthesis via cyclooxygenase (COX) inhibition, with selectivity for COX-2 over COX-1.
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.
200 to 400 mg orally every 6 to 8 hours as needed; maximum daily dose 1200 mg.
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.

Terminal elimination half-life approximately 7.5 hours; in elderly or renal impairment, half-life may be prolonged up to 10 hours, requiring dose adjustment
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.
Primarily renal (60% as metabolites, <1% unchanged); biliary/fecal (30-35%)
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.
