Preparation and Evaluation of Eudragit Gels. II: In Vitro Release of Salicylic Acid, Sodium Salicylate, and Ketoprofen from Eudragit L and S Organogels

“…The b values in the following equations could be obtained from the slopes of these lines: k=a(Nb (5) where N is the agitation rate, k corresponds to the mass flux or apparent dissolution rate constant, and a and b are experimental constants. If the release is diffusion controlled, These parameters were calculated from the following equation: log k = log a + (b * log N), where kis the apparent dissolution rate constant, and N is the agitation rate expressed as angular velocity.…”
