[Description of the process of in vitro liberation of matrix tablets].
After a short description of the drug liberation process from a porous matrix the influence of the matrix forming substance on the drug liberation is characterized. The compression process is the decisive step in forming the hydrophobic, nondissolved matrix. The temporal lapse of the in vitro liberation process of the model drug quinidine is demonstrated by means of electronmicroscopical photographies.
