有些饮料放置久了,其中的果肉等成分会沉底,因此喝前要摇一摇。糖浆和混悬剂这两类药物也类似,用前需要摇匀。如果您喝糖浆前没有摇匀的习惯,可能有这样的感受:开瓶后喝前一半时,药味比较淡,越往后喝药味越浓。这是因为糖浆中加了一定量的蔗糖改善药物口感,如果用前不摇匀,药物和蔗糖会集中在下部。在喝前一半糖浆时,可能没有达到最有疗效的浓度。 Some drinks placed for a long time, of which the ingredients such as pulp will sink, so shake before drinking. Syrup and suspensions are similar for both types of drugs and need to be shaken before use. If you drink syrup before there is no shake the habit, there may be such a feeling: After opening the first half of the drink, the medicine is relatively light, the more the later drink more concentrated. This is because a certain amount of sucrose is added to the syrup to improve the mouthfeel of the medicine, and the medicine and sucrose concentrate on the lower part if not shaken before use. When you drink the first half of the syrup, you may not achieve the most effective concentration.
