Abstract

In general, colon-specific delivery of a drug decreases systemic absorption and increases therapeutic concentration of the drug at the target site. N-succinylglutam-1 or 5-yl celecoxib (SG1C and SG5C) were prepared as a colon-specific prodrug of celecoxib, a selective Cox-2 inhibitor, and investigated whether the celecoxib derivatives could deliver celecoxib to the target site and improve cardiovascular toxicity and therapeutic effectiveness for the treatment of familiar adenomatous polyposis. SG1C and SA5C were cleaved to release celecoxib in the cecal contents while stable in small intestinal contents. The cecal release of celecoxib was much greater for SG1C than SG5C. SG1C administered orally was barely detected in the blood and urine. SG1C delivered much greater amount of celecoxib to the large intestine while keeping the plasma concentration of celecoxib at much lower level compared with oral administration of free celecoxib. Consistent with these pharmacokinetic results, SG1C supplied a greater concentration of celecoxib for the entire colonic tissue and did not change the serum level of 6-keto-PGF1α whose decrease is associated with the cardiovascular toxicity of celecoxib. Taken together, colon-specific delivery of celecoxib using a prodrug approach may be a useful strategy to improve toxicological and pharmacological properties of celecoxib.
