pubmed:abstractText |
The in vitro aqueous behaviour of a metacryloyloxyethyl [2-(acetyloxy)-4-(trifluoromethyl)]benzoate (THEMA)/N,N'-dimethylacrylamide (DMA) copolymer with a THEMA molar content of 39% (labeled THDMA39) has been investigated. This composition has been selected to achieve a system able to keep both the non-water solubility during the release and the resorbability (and the water solubility) after the completion of the drug release. This copolymer exhibited, at pH 7.4, a constant release during several months, very interesting for a long term treatments required for the application of some cardiovascular devices. A kinetic model has been developed to explain the pseudo-zero-order kinetics of the release process. This model, which considers (from the aqueous studies) a linear increase with time of the amount of water present in the polymeric matrix, has been able to fit adequately the experimental data.
