Administering carotenoids, and in particular xanthophyll carotenoids, or analogs or derivatives of astaxanthin, lutein, zeaxanthin, lycoxanthin, lycophyll, or lycopene to a subject undergoing treatment with COX-2 inhibitor drugs may reduce at least a portion of the adverse side effects associated with administration of COX-2 selective inhibitor drugs. The carotenoids, or analogs or derivatives thereof may be administered to a subject prior to, at the same time as, or after the commencement of COX-2 selective inhibitor drug therapy. The carotenoids, or analogs or derivatives thereof may be administered to a subject concurrently with COX-2 selective inhibitor drugs therapy. The carotenoids, or analogs or derivatives thereof may be incorporated into pharmaceutical preparation in combination with the COX-2 selective inhibitor drug or may be administered separately. Administration of the analogs or derivatives described herein may reduce peroxidation of LDL and other lipids in the serum and plasma cell membranes of subjects undergoing COX-2 selective inhibitor drug therapy. Administration of the analogs or derivatives described herein may reduce the incidence of deleterious clinical cardiovascular events undergoing COX-2 selective inhibitor drug therapy.

This invention has disclosed a method for preparation of food-grade zeaxanthin through chemical isomerizaton reaction from lutein. The technical issues to be solved in this invention are quite low product yield obtained with existing methods, need of purification treatment process, and inadaptability to industrialized production. The technical schemes of this invention are: a. Mix xanthophyll crystal or its fatty acid ester with food-grade glycol or propylene glycol, for full dissolution under 60-90° C. temperature. Add organic alkali into the mixed liquor acquired from step 1, for isomerization reaction to take place under inertial environment. c. Dilute the reaction solution gained from step b with the mixed solution of deionized water and ethanol, and separate the obtained crystal with conventional separating method. d. Vacuum dries the acquired crystal from step c, to get the zeaxanthin crystal. Glycol or propylene glycol is used in this invention for isomerization reaction under inertial environment after it has fully dissolved raw material under proper temperature. The product yield is reachable to more than 60%, very adaptable to industrialized product, without the need for further purification treatment.
