    Release kinetics of tramadol hydrochloride from solid drug formulations

  • Original language description

    The aim of this paper is to present the use of a reaction and a dissolution kinetic approach for evaluating the dissolution profile of a drug. As model substances, two controlled-release formulations (with different type of matrix) with tramadol hydrochloride were chosen. Release kinetics of tramadol hydrochloride was studied at isothermal conditions (37 oC) and at different pH values for media used for dissolution. The dissolution profiles obtained by using HPLC with UV detection were fitted by the first-order kinetic model, Korsmeyer-Peppas, Higuchi, and Weibull models. The main results of regression analysis were the determination of the first-order release rate constant (k1), the release exponent (n) from Korsmeyer-Peppas model, Higuchi constant (KH), and the parameters of Weibull model.
