  • Patent number: 9447065
    Abstract: The present invention provides a pharmaceutical composition which prevents from decreasing the blood exposure of the third generation coxib-drugs, a process for preparing the said pharmaceutical composition and its use. It has been founded in this invention that adding a basic amine or a basic amino acid, or a cyclodextrin to the third generation coxib-drug can afford a pharmaceutical composition which can prevent from decreasing the blood exposure, AUC and bioavailability. The pharmaceutical composition of the present invention has also good stability, which is useful for drugs. Namely, the technological thought that adding a basic amine or a basic amino acid, or a cyclodextrin to the third generation coxib-drug can prevent from decreasing the blood exposure, AUC and bioavailability has been established in this invention.
