Efficiency of kollicoat EMM 30 D and SR 30D as matrix forming material was investigated. It was found that, theophylline loaded granules prepared with these two polymers could not sustain drug release for a significant period of time. However, compression of these granules into tablets retarded drug release for up to 8 hours. Release was faster from EMM 30D polymeric system than that from SR 30D matrix. Effects of fillers and rate modifiers on drug liberation have been assessed. Incorporation of Avicel RC 591 and starch caused substantial release of theophylline from both the polymeric systems. Avicel PH 101 intensified the retardation effect of both EMM 30D and SR 30D on theophylline release. HPMC 50 cps, when added to the matrix, caused the release of theophylline to follow near zero order pattern. Increasing the content of HPMC in both EMM 30D and SR 30D compressed tablets decreased the rate and extent of theophylline release. In the presence of excipients, no significant differences between rate and extent of drug release from EMM 30D and SR 30D systems were found. Biexponential equation was applied to explore and explain drug release kinetics. It was found that drug release followed Fickian or case I kinetics from EMM 30D compressed tablet while anomalous or non-fickian kinetics of drug release was observed for SR 30D system.

Ordered mesoporous silicates as matrices for controlled release of drugs Interest in and thereby also development of ordered mesoporous silicates as drug delivery devices have grown immensely over the past few years. On hand selected cases from the literature, the power of such systems as delivery devices has been established. Specifically, it is shown how it is possible to enhance the release kinetics of poorly soluble drugs by embedding them in mesoporous silicates. Further critical factors governing the structure and release of the model drug itraconazole incorporated in an SBA-15 matrix are briefly reviewed. The possibility of functionalizing the surface of mesoporous matrices also under harsher conditions offers a broad platform for the design of stimuli-responsive drug release, including pH responsive systems and systems which respond to the presence of specific ions, reducing agents, magnetic field or UV light, whose efficiency and biocompatibility has been established in vitro.
