“…This relationship dictates the rate of solvent penetration into a capillary bed and thus has a direct impact on disintegration. [22][23][24] On the basis of the eqs 1-3, for a given substrate with constant ␥ SV , wetting will be influenced by the interfacial tensions at the solid-liquid and liquidvapor interfaces. 18,19 It is clear that the processes associated with surfactant wetting are important in the dissolution of dosage forms.…”
