During formulation development, efficiently integrating聽颈苍听惫颈迟谤辞聽dissolution testing can significantly improve one's ability to estimate聽颈苍听惫颈惫辞聽performance and aide in the selection of premier drug candidates. The concept of聽颈苍听惫颈迟谤辞鈥摼辈蕴咕北勾�聽relationship/correlation has garnered significant attention from pharmaceutical scientists to predict expected bioavailability characteristics for drug substances and products. The present work illustrates a comparative evaluation of聽颈苍听惫颈迟谤辞聽tests to access crystalline carbamazepine and various types of amorphous and crystalline dispersions of carbamazepine and Eudragit庐聽L100 produced by spray drying, including a membrane-permeation dissolution methodology and nonsink dissolution. To establish the best model, parameters such as pH, membrane constitution, and dissolution media composition were investigated. The聽颈苍听惫颈迟谤辞聽results were compared against聽颈苍听惫颈惫辞mice pharmacokinetic studies and qualitatively, the membrane-permeation dissolution methodology correlated well with聽颈苍听惫颈惫辞. Various correlations were performed in order to evaluate the optimal model for characterizing the relationship. Results exhibited a coefficient of determination (R2) values of 0.90 and 1.00, depicting a linear relationship of the data in comparison. Therefore, for the current formulation system (drug/polymer/technique), membrane-permeation dissolution can guide formulation development and potentially reduce the number of animal and clinical pharmacokinetic studies required.
