A new application of MCM-41 mesoporous materials has been developed. Two ki
nds of surfactants, C16TAB and C12TAB, have been employed to get different
pore sizes. The samples were disk-shaped conformed before and after chargin
g with ibuprofen, an antiinflammatory drug. In all the cases the weight per
cent ratio of drug/MCM-41 was 30%. The drug release plots show a different
behavior depending on the method for charging the drug in the material but
not on the employed surfactant.
