  • Stabilized oral pharmaceutical composition
    Publication number: 20050112197
    Abstract: An orally deliverable pharmaceutical composition is provided comprising an aminosulfonyl-comprising drug, for example a selective cyclooxygenase-2 inhibitory drug such as celecoxib, and a solvent liquid comprising a polyethylene glycol and one or more free radical-scavenging antioxidants. At least a substantial part of the drug is in dissolved form in the solvent liquid. The composition has rapid-onset properties and is useful in treatment of cyclooxygenase-2 mediated conditions and disorders.
    Type: Application
    Filed: October 20, 2004

  • Pharmaceutical composition having reduced tendency for drug crystallization
    Publication number: 20030045563
    Abstract: An orally deliverable pharmaceutical composition is provided comprising a drug of low water solubility, a solvent liquid that comprises at least one pharmaceutically acceptable solvent, and a turbidity-decreasing polymer, wherein (a) a substantial portion, for example at least about 15% by weight, of the drug is in dissolved or solubilized form in the solvent liquid, and (b) the polymer is present in an amount sufficient to substantially inhibit crystallization and/or precipitation of the drug in simulated gastric fluid.
