Abstract: To evaluate physicochemical changes in ciprofloxacin following incorporation in Carbopol polymeric composites. Methods: The ciprofloxacin and Carbopol were mixed in water in a drug:polymer ratio of 1:5 (w/w) and homogenized to produce uniform composites. X-ray powder diffraction analysis of the pure ciprofloxacin and the Carbopol polymeric composites of the drug were obtained using a powder diffractometer. Spectra for the materials were also generated by Fourier transform infrared (FTIR) spectroscope interfaced with an infrared (IR) microscope operated in reflectance mode. Results: Based on the Hanawalt system, three prominent x-ray diffractogram (XRD) peaks of the pure ciprofloxacin and the drug in the polymeric composites exhibited d-spacing at similar 2 values, but the relative intensity of these peaks was higher in the polymeric composites. FTIR analysis indicates that there were intermolecular hydrogen bonding and esterification between the drug and polymer in the polymeric ...
