Versuchsvorschrift
41 grams of nimesulide-sodium salt/βCD complex of 1:1 molar ratio are obtained as a yellow fine powder. The resultant nimesulide content is 20.0±0.2% measured by UV-spectrophotometry. Solubility properties are such that 100 mg of the complex can be dissolved in 6 ml of distilled water, resulting in a slightly opalescent solution with approximately 3.5 mg/ml nimesulide content. The solution has a pH value of 8.3±0.1.
