Collaboration between HPMC and NaCMC in order to Reach the Polymer Critical Point in Theophylline Hydrophilic Matrices
(Hindawi Publishing Corporation, 2012)
Percolation theory has been applied in order to study the existence of critical points as well as the possibility to find a “combined percolation threshold” for ternary hydrophilic matrices prepared with HPMC, NaCMC, and ...

Comparison between polymeric excipients using SeDeM expert system in combination with mathematical modeling and quality control tools
(Elsevier, 2023-09)
Based on the quality by design approach, we used the SeDeM expert system to assess seven polymers of different chemical nature and molecular weight for their use in direct compression. Because the SeDeM system fails by not ...

Application of a new mathematical method for the estimation of the mean surface area to calculate the percolation threshold of Lobenzarit dissodium salt in controlled release matrices
(The Pharmaceutical Society of Japan, 2004-07)
One of the practical handicaps for the application of the percolation theory to estimate the percolation threshold of drugs in controlled release systems is the fact that the dissolution studies must be carried out so that ...
