The kinetics of degradation of ceftazidime in aqueous solutions containing various carbohydrates (glucose and fructose) or polyhydric alcohols (sorbitol and mannitol) was investigated over the pH range 9.92-10.93 at 35 degrees C. A relationship between the degradation rate and the hydroxy compound concentration was observed at each pH studied, and the rate-accelerating effect of the compounds was directly proportional to the hydroxide ion activity.
