Release of the Drugs from Silica Aerogels

The release of ketoprofen from the ketoprofen-aerogel formulation, prepared by the adsorption from supercritical CO2 solution, is much faster than the dissolution of 

Modified Siiica Aerogels Influence of Functional Gr on the Drug Adsorption and Release Kinetics 

the decrease of the adsorbed amount of drugs after esterification of Ae aerogel cm be very unfavourable for the production of pharmaceutical formulations, since t e aeroge wi lower adsorption capacity requires higher amounts of the earner for a gw era this case, it would be favourable to modify the silica aerogels with faj-boxylic group,
