This document discusses in process quality control (IPQC) and finished product quality control (FPQC) tests for tablets. It begins with introducing the concepts of quality, quality control, IPQC and FPQC. It then lists and describes common tests conducted for tablets, including tests for size and shape, colour and odour, hardness, friability, content uniformity and dissolution. Standard acceptance criteria for many of the tests are also provided. The document emphasizes that IPQC and FPQC are important to control quality, identify errors, and ensure product specifications are met.

QUALITY
 Quality is a broad term which includes suitability of drugs and
products for their utilization which is decided by their efficiency
and safety, according to label claim, or as promoted or
publicized, their conformity to specifications about identity, purity
and other characteristics.
 The quality of any product must be built during plant
construction, product research and development, purchasing of
materials, production, testing, inspection, labelling, storage and
distribution.

4. QUALITY CONTROL
■ The International Standard of Organization (ISO) definition states
that quality control is “the operational techniques and activities that
are used to fulfil requirements for quality.
■ It is a part of GMP
■ To eliminate errors and production of end product of given
specifications

FINISHED PRODUCT QUALITY CONTROL (FPQC)

5. IN PROCESS QUALITY CONTROL (IPQC)
05/05/2021 5
 The function of in-process quality controls is to monitor and if
necessary, adaptation of the manufacturing process in order to
comply with the specification
 Be carried out before the manufacturing process is completed
 Physical parameters and its quality attributes
 Involve control of equipment and environment too

6. FINISHED PRODUCT QUALITY CONTROL (FPQC)
■ These are the test carried out after completion of product
manufacturing process
■ Qualitative and quantitative analysis of product
■ Determines the test procedures and acceptance limit
■ The product must comply with the acceptance limit for the approval of
complete batch manufactured.

7. OBJECTIVES
■ Monitor all the features of product that contributes to the
quality
■ Prevent errors
■ Provide product as per specifications
■ Identify or detect any error
■ Rectify error

9. SIZE AND SHAPE
according to need of the dose requirement and can be dimensionally describe,
monitored and controlled.
It is determined by the tooling during the compression processes

10. COLOUR AND ODOUR
To mask the original characteristics for consumer acceptance
Uniformity
The taste is the important factor when is comes to chewable tablets while odor
in vitamins.
05/05/2021 10

11. UNIQUE IDENTIFICATION MARKING
Embossing, engraving or printing
Mainly for Identification purpose
Eg. Company name or product code or specific symbol on it
05/05/2021 11

12. THICKNESS
Dimensional variable related to the process
A single tablet dimensions are measured and this is done for the whole batch
It should in between -5 and +5 mm or standard dimensions

13. HARDNESS
The resistance of the tablet to chipping, abrasion, or breakage under conditions of
storage, transportation, and handling, before usage, depends on its hardness.
Hardness is affected by- compression of tablet and compressive force
-method of granulation.
Limits -
5 kilograms minimum and 8 kilograms maximum.

14. FRIABILITY
This property is related to hardness of tablets.
Friability =
𝐼𝑊−𝐹𝑊
𝐼𝑊
× 100
where, Iw = Total Initial weight of tablets
Fw = Total final weight of tablets.
As stated by USP if conventional compressed tablets that loss less than 0.5 % to
1 % (after 100 revolutions) of their weight are generally considered acceptable

15. WEIGHT VARIATION
Difference in weight of tablets in a batch is measured
Average Weight (mg) Percentage Deviation (%)
130 or Less 10
130 – 324 7.5
More than 324 5
The above table is as per USP
CONTENT UNIFORMITY
This helps to understand the consistency of active pharmaceutical ingredients in
the tablets
This gives potential for efficacy of tablet in a batch and from batch to batch

16. CONTENT OF ACTIVE INGREDIENTS
The content of active ingredients can be determine by the assay procedure
Weight of Active Ingredients in Each
Tablet
Subtract from Lower Limit for Samples
of
Add to the Upper Limit for Samples of
15 10 5 15 10 5
0.12 g or less 0.2 0.7 1.6 0.3 0.8 1.8
More than 0.12 g But less than 0.3 g 0.2 0.5 1.2 0.3 0.6 1.5
0.3 g or more 0.1 0.2 0.2 0.2 0.4 1.0
The above table is as per I.P. limits

17. DISINTEGRATION TEST
The disintegration test is used to show how quickly the tablet breaks down into
smaller particles, allowing for a greater surface area and availability of the drug
when taken by a patient

19. DISSOLUTION TEST
Dissolution testing measures the extent and rate of solution formation from a
dosage form
The dissolution of a drug is important for its bioavailability and therapeutic
effectiveness.
In dissolution solid mass is transfer in liquid medium that is it is aqueous solubility
dependent process
More the aqueous solubility more is the dissolution rate
Dissolution test is based on following processes-
1. wetting
2. Solubility
3. Swelling
4. Diffusion

22. CONCLUSION
05/05/2021 22
Standard operating procedures must be established and followed to compare
the quality of the product formed.
All the materials should be tested during and after the manufacturing process
to control the quality of the product.
In process and finished product test are carried out so as we get early
warning of any error in the product and can be rectified soon
