Quality Assurance department is responsible for assuring that the quality policies adopted by a company are followed and in most organizations it serves as the contact with regulatory agencies and are the final authority for product acceptance or rejection. It also helps to prepare the standard operating procedures (SOP) related to the control of quality

Quality assurance means the sum total of the organized arrangements made with the object of ensuring that products will be at the quality required by their intended use. It is thus GMP plus factors outside the scope of ISO guidelines.

The function of QA starts from raw materials and continues up to released products. The function of QA in a pharmaceutical is given below.


Environment of the suppliers are also sensitive for purchasing of raw materials. QA checks the environment before purchasing the active pharmaceutical ingredients (API).


  • Identification of raw materials (RM / PM)
  • Check the quality by QC
  • Orientation of raw materials.
  • Orientation of packaging materials.
  • QA inspection and report submission to the head of QC.
  • Sampling for,

o Lab sample.

o Microbiological sample.

Now a days the manufacturing of Pharmaceuticals is quite complex & there also arise some responsibilities; for example ethical, legal and economic responsibilities. These responsibilities are immensely important for the production, control & marketing of quality products. A systematic checking from the raw materials in process, Packaging materials, labeling & finished products can ensure quality products. This is the Prime concern of the industrial Quality & Compliance Department. The Concept of total Quality refers to the process of striving to produce a perfect product by a series of measures requiring an organized effort by the entire company to prevent or eliminate errors at every stage in the production. During our training part in QC, we observed that RANGS performs almost everything that ensures quality of medicine

Quality control (QC) is one of the major and global concerns for the entire sector in any industry or company. It is the combination of skills personnel, valided method, part of GMP which is concerned with sampling, specification and testing to ensure that the necessary and relevant taste are carried out and that materials are not released for used until the quality has been judged to be satisfactory. This part is responsible for chemicals test, identification, and separation of any sample.

After packaging of the product, packed materials such as strips, ampoules, blisters, bottles etc are checked for accuracy. It is not possible to check all the products of a batch. Random sampling on the basis of the following rule checks them


Where N=no of container

After sampling every sample is checked. Usually three types of mistakes are checked———

1. Critical:this is the problem, which cannot be overlooked. E.g.-DAR No. (Drug administration registration number).If DAR is wrong the whole batch will be discarded.

2 Major: For this type of problem reprocessing is possible. E.g.-spelling mistake.

3. Minor: Simple mistakes which can be overlooked.


GMP specification

a. For each batch of drug product, there should be appropriate laboratory determination of satisfactory conformance to its finished product specification prior to release.

b. Drug products failing to meet the established specifications and other relevant quality criteria should be rejected. Reprocessing may be performed if possible but the reprocessed product should meet all the specification and other quality criteria prior to its acceptance and release.

Finished product should be checked in the laboratory by suitable procedures. These tests are designed to determine compliance with specification and hence arc critical factor for the QC department.

Each lot of products is tested to ensure identity, quality, purity and potency.

Q.A authorizes the releases for further processing based on actual physical, chemical & biological laboratory testing

The following tests are performed here for the finished product-


  • Parameter checked—
  • Description
  • Identity
  • Diameter
