内服水剂往往放置时間稍长就会發生沉淀、霉坏及混濁。为了提高药品质量,我們二年来在实际工作中进行了一些防霉的試驗,茲将初步結果介紹出来供参考。内服水剂可分为單一水剂与复方水剂。單一水剂如10%溴化鈉等,复方水剂如稀鹽酸合剂等,均在配得后7—12天内即霉坏,發生灰褐色、白絮狀团或黑粒狀等異物,浮游于药液上面或药液中,影响药品效力,造成浪費。
Oral liquids tend to settle for a long time, and they may cause sedimentation, mildew, and turbidity. In order to improve the quality of medicines, we have carried out some mildew-proof tests in actual work in the past two years. The preliminary results are hereby introduced for reference. Oral liquids can be divided into single water and compound water. Single water agents such as 10% sodium bromide, compound water agents such as dilute hydrochloric acid mixture, etc., are moldy within 7 to 12 days after being formulated, and occur foreign matter such as grayish-brown, white floc-like clusters or black-grained particles. Above the drug solution or in the drug solution, it affects the efficacy of the drug and causes waste.
