Celecoxib is provided in a porous matrix form wherein the dissolution rate of the drug is enhanced when the matrix is contacted with an aqueous medium. The porous matrix yields upon contact with an aqueous medium nanoparticles and microparticles of celecoxib having a mean diameter between about 0.01 and 5 .mu.m and a total surface area greater than about 0.5 m.sup.2 /mL. The dry porous matrix preferably is in a dry powder form having a TAP density less than or equal to 1.0 g/mL. The porous celec...

There is provided a method of rapidly relieving pain in a mammalian, preferably human, subject. The method comprises orally administering to the subject an effective pain-relieving amount of a composition comprising celecoxib formulated in such a way as to provide, when tested in fasting humans in accordance with standard pharmacokinetic practice, a blood plasma concentration profile of celecoxib in which a concentration of about 250 ng/ml is attained not later than about 30 minutes after oral a...

Celecoxib, a COX-2 specific non-steroidal anti-inflammatory agent, is provided in combination with DFMO for the prevention and/or treatment of cancers. Provided with the present invention are pharmaceutically acceptable compositions that include a non-steroidal anti-inflammatory agent, celecoxib, together with an effective amount of difluoromethylornithine.
