摘要: The performance of compressed tablet drug delivery systems made using polymeric materials depend on multiple factors, such as surface properties like contact angle, free energy and water absorption rate, besides the release mechanisms driven by kind polymer used. Hence, it should be possible to establish a relationship between kinetics. Compressed tablets with different proportions poly(maleic acid-alt-octadecene) potassium salt (0%, 10%, 20%, 30% 40%) were prepared. Blends model (ampicillin trihydrate) material analyzed DSC. determined sessile drop method, while was semi-empirical Young-Dupre, Neumann OWRK models. profiles simulating in vitro conditions (buffer solutions pH 1.2 7.4 ionic strength 1.5 M at 37 °C (310.15 K)). A kinetic analysis dissolution models (zero order, first Higuchi Korsmeyer-Peppas) realized. results showed significant effect proportion both release, indicating thermodynamic properties.
