以计算法代替图解法确定药品有效期的探讨

Study on Evaluation of Expiry Date for Pharmaceuticals Using Calculating Method as a Substitute for Graphic Method

计算法较图解法更为简便，它可避免由于观察读取图上刻度所致的误差，能精确地估计有效期内或有效期外的相当于标示量的含量百分数。本方法可应用于新药的研究或已制成的药品质量监督管理，提供科学依据。

Calculating method for the evaluation of drug expiry date is more convenient than graphic method. It prevents errors due to reading on graphs, and can calculates precisely the estimated potency of the labeled amount at any time within the expiry date or out that. It is useful for investigation on quality control of new pharmaceuticals and drugs on markets.
