ABSTRACT
OBJECTIVE:
To prepare Idebenone solid dispersion,and to investigate its dissolution rate in vitro.METHODS:
Us-ing Poloxamer 407(P407)as carrier,the influence of preparation methods(solvent method,melting method)and the ratio of the drug to P407(1∶1,1∶3,1∶8)on the dissolution of drug were investigated by single factor design. The state of idebenone in ma-trix of solid dispersion was further determined by using differential scanning calorimetry (DSC) and X-ray powder diffraction (XRD).RESULTS:
Idebenone solid dispersion prepared by solvent method(the ratio of the drug to poloxamer was 1∶3)showed dissolution rate of 80%. The majority of idebenone existed in the solid dispersion at amorphous forms or molecular state. CONCLU-SIONSIdebenone solid dispersions with high dissolution rate in vitro is prepared successfully.
