Abstract: A series of mesoporous silica with variable pore structures were prepared. The influence of mesoporous structure on drug release profiles was studied. It is found that mesoporous pore structure has a great effect on the drug release rate. The cubic pore structure MCM-48 has a faster drug release rate than that of MCM-41 system; while SBA-16 with “cage-like” pore structure system has the lowest drug release rate.

Key words: Mesoporous silica, Pore structure, Captopril, Release property
