Targeted delivery of fenamates with aminated starch
Aim: To develop controlled-release tablets based on aminated starch. Materials & methods: Aminated starch was characterized with Fourier transform infrared and x-ray diffraction. Thermogravimetric analysis confirmed the preferential oxidation of crystalline region of starch. Results: The tablets achieved an initial fast release of fenamates, which slows down after 12 h. Drug release was not completed in the simulated intestinal media, which may be due to the stability of imine bond in aminated starch at weakly acidic pH. Drug release was completed in simulated acidic media due to the hydrolysis of imine functionality at strongly acidic pH. Conclusion: Aminated starch with an imine functionality may serve as intestine targeted, controlled drug-delivery system. Mucoadhesive potential of tablets further supports this observation.
