Critical points in ethylcellulose matrices: Influence of the polymer, drug and filler properties
Percolation theory has been applied to study the drug re- lease behaviour in multicomponent inert matrices con- taining ethylcellulose as a matrix forming polymer. Glo- bal influence of major formulation factors such as polymerviscosity, polymer particle size, drug and filler…
