中药注射剂为中药材经提取精制后含综合成分的提取物。其复杂的化学成分和不同的化学性质,对针剂澄明度有较大的影响。澄明度是中药注射剂质量中较常见的问题。PH值的调节与控制在改善药液的澄明度、确保制剂质量中起了重要作用。现从如下几个方面加以阐述: 一、提高有效成分的溶解度中药注射剂多为有效成分的水溶液,单
Traditional Chinese medicine injections are extracts containing synthetic ingredients extracted and refined from Chinese herbal medicines. Its complex chemical composition and different chemical properties have a greater impact on the clarity of the injection. Clarity is a common problem in the quality of traditional Chinese medicine injections. The adjustment and control of PH value play an important role in improving the clarity of the liquid and ensuring the quality of the preparation. Now from the following aspects are described: First, to improve the solubility of active ingredients Chinese medicine injections are mostly aqueous solutions of active ingredients, single
