Versuchsvorschrift

To demonstrate the release of the ciprofloxacin from the cryogel in a simulated body fluid environment, the cryogel/ciprofloxacin disk was immersed in 1.0 ml portions of 0.9% NaCl in distilled water for 1 hour, after which the procedure was repeated. HPLC analyses of the saline extracts for ciprofloxacin were made. The pH of these saline extracts was found to be 5.5. The initial content of ciprofloxacin in the disk was estimated to be 15 mg. The results are shown in Table 9.
