Abstract: Hydrophilic matrix tablets comprising metoprolol salts (succinate and tartrate). and hydrophilic natural colloids such as carrageens, alginates and xanthan, were obtained by direct compression on a single station tablet press, in order to obtain a modified release of the drug. The influence of the natural polymer, the polymer ratio on the compresibility of the tablet and their influence on in vitro release of the active substance, were studied. The tablets were evaluated for weight uniformity, drug content, hardness and friability. The study demonstrated that it is possible to fabricate modified release tablets of metoprolol salts hydrophylic natural colloids such as carrageens, alginates and xanthan gum and the drug release was found to be dependent on the ratio and type of the matrixing agents.
Keywords: alginates, carrageens, drug release, hidroxypropyl methyl cellulose (HPMC), hydrophylic natural colloids, metoprolol ((+)-1-(isopropyl) amino)-3-[p-(2-methoxyethyl)]-2-propanolol) succinate or tartric salt and xanthan gum.
