The development on the software on fast inquirg system of drugs quality information is an effective reserch to make the best use of the drugs quality information,enhance the accuracy of supervision and sampling to be inspect for drugs,solve the problem of working on point and so on.

The method can be applied in the process that calculates three indicators such as accuracy, timeliness and value, and contributes to the scientific evaluation of product information quality (PIQ).

A method for measuring data quality and for computing intermediate data quality and final information product quality is proposed by analyzing and studying information manufacturing systems.

Building of product quality information and it s feedback system was emhpasized introduced from some respects such as scientific managed to product, exactly known well quality condition, analyzed quality changed rules, realized closedring control of quality, raised product quality and extended service life.

This paper analyzes the problems existing in drug manufacturing, distribution and using, and countermeasures are offered to strengthen the Management of drug buying and selling receipts and guarantee the drug quality.

Taking the ampicillin as example,a new way--idealized pattern is used to evaluate the drug quality.

By combining the occupational experience of drug dispensation and the scientific management for drug quality,we suggested suitable measures to ensure the drug quality and safety in clinical use.
