识别药品的有效期、失效期对保证患者用药的安全有效至关重要,以下分别介绍识别国产药、进口药有效期的方法。 国产药 由于药品理化性质及贮存条件的差异,药品的有效期往往长短不一。一般来说,药品的有效期为1年～5年。国产药品有效期可按生产批号推算,例如:批号为950703,表明该药是1995年7月生产的第3批药品,有效期若为2年,则该药可使用至1997年7月;如某药有效期标明为1998年6月,即该药可使用至1998年6月30日为止;还有的药品标明失效期为1998年12月,即表示该药可使用至1998年11月30日。
Identify the validity of drugs, expiration date to ensure the safety of patients with medication is essential, the following were introduced to identify domestic and imported drugs, the validity of the method. Domestic drugs Due to the differences in physicochemical properties and storage conditions, the expiration dates of medicines often vary in length. In general, the drug is valid for 1 year to 5 years. For example, the batch number is 950703, indicating that the drug is the third batch manufactured in July 1995. If the expiration date is two years, the drug can be used until July 1997; if a drug The expiry date is June 1998, meaning the drug will be available until 30 June 1998. Others indicate the expiry date of December 1998, indicating that the drug will be available until 30 November 1998.
