ABSTRACT
In recent years, silica aerogels have attracted more and more attention due to their surprising properties and their existing and potential applications in wide variety technological areas. Silica aerogel is a nanostructured material with high specific surface area, high porosity, low dielectric constant, low density and outstanding heat insulation properties. Release of some active ingredients from the aerogel-drug formulation is faster than that of the crystalline drugs and commonly used formulations, can be explained by both the increase in the specific surface area of the drug adsorbed on the aerogel and its non-crystalline structure. Aerogel-drug formulations may be effectively used as drug delivery systems for drugs whose immediate release is desirable. It can also be used as a carrier for drug delivery, propellant replacement, to improve flow properties and molecular imprinting. This review address synthesis, properties, and characterization of silica aerogels, application in field of pharmaceuticals and its future prospects.
