Abstract

<jats:p>The purpose of this work was to incorporate superporus hydrogels for cefditoren pivoxil by using polymer like poly acrylic acid aqua cc polymer and composite agent like cross linked sodium carboxy methyl cellulose in the presence of N,N-methylene-bis-Acrylamide as crosslinking agent. Pluronic F-127 as a stabilizer and ammonium per sulfate and tetramethylene diamine as a initiator pair. Poly acrylic acid aqua cc polymer-cross linked sodium carboxy methyl cellulose superporus hydrogels of cefditoren pivoxil were incorporate by gas blowing technique. The reaction  of pH on the swelling ratio was decisive. Swelling reversibility research was also achieve. Fourier transform infrared spectroscopy analysis and scanning electron microscopy studies were assume to indicate the drug loaded superporous hydrogels, while dissolution studies were achieve to assess release characteristics. Swelling was hugely depending on the term of crosslinking and the quantity of the polymer existing in formulation. The huge amount of cross-linking agent reduced the swelling ratio. The superporous hydrogels were hugely perceptive to pH of swelling medium, and exhibit reversible swelling and de-swelling behavior during still keep their mechanical stability. Apparent density was reliant on the amount of the superporous hydrogels and reduced with developing crosslink density. Degradation kinetics reveals that poly acrylic acid aqua cc polymer superporous hydrogels had good water holding potential. Drug release was similar to quantity of cross-linking agent. The studies report that poly acrylic acid aqua cc polymer superporous hydrogels can be used as a Gastroretentive drug delivery system in view of their swelling characteristics in acidic pH.</jats:p>
