Tools in the dept. of quality assurance that relies on trained personnel with specific knowledge and skills are as follows:

1.Quality management system(review of non-conformities, control of changes, corrective and preventive measures).

2.Approvals of equipment quality and validations of methods

3.Process analysis(in the process analysis, trends to find improvements, root causes of problems and identification of surplus and valueless activities are analyzed).

4.Identification,assessment and control of the quality risks(risks affecting the quality of products as well as the risks of cross contamination based on QRM protocol are identified,evaluated and controlled).

5.Periodic inspections(an effective tool to ensure that the best of approved practices and procedures are utilized).

The control tools in quality management include statistical quality control techniques,multi-criteria decision making science(MCDM) and so on.

In addition to the above mentioned points,the quality system of pharmaceutical products(PQS) runs based on the company approach to the legal requirements of the Food and Drug Administration of Iran(IFDA) and the guidelines of WHO,PIC/S,FDA,EU as well as the quality management system ISO9001,and to achieve a product free of any flaws and defects  based on a program compiled under the title of VSM(Validation of Systems and Methods) is in operation at all levels.

It is imperative to observe the principles of the integrated system of quality by all employees in order to move towards effective management and we are committed to comply with the following:

  • customer satisfaction through increasing product quality
  • increasing the efficiency and efficacy of the employees performance
