汤剂是指药材加水煎煮去渣后所得的液体剂型。它是临床应用历史悠久的剂型之一。随着我国医药事业的迅速发展以及人民对医药工作愈来愈高的要求,这一古老剂型的一些缺点便愈显得与形势不相适应。如临床配方中,病人需带回数包药材饮片自行煎煮,而煎出的汤剂的体积较大。这就给病人在应用过程中造成许多不便。此外,汤剂的门诊配方工作量大,也是它存在的一个问题。 Decoction refers to the liquid dosage form obtained by adding boiling water to the residue. It is one of the longest clinical dosage forms. With the rapid development of China’s pharmaceutical industry and people’s increasing demand for medical work, some of the shortcomings of this ancient dosage form appear to be incompatible with the situation. For example, in the clinical formula, the patient needs to bring back a few packets of medicinal materials to decoct on their own, and the volume of decoction decocted is larger. This causes many inconveniences to the patient in the application process. In addition, the volume of outpatient prescription formula of decoction is also a problem that exists.
