Questions and Answers
Explain the process of weight variation testing for tablets according to the USP method.
The weight variation testing for tablets according to the USP method involves taking 20 tablets randomly, weighing each one individually, recording the weight of these tablets, and then calculating the average weight (total weight divided by 20). The percentage weight variation can then be determined from the average weight.
How is weight variation adjusted in tablet production?
Weight variation in tablet production is adjusted by the input of granules present in the die at the moment of compression, which is determined by the distance between the upper and lower punch.

Study Notes
Weight Variation Testing for Tablets
- Weight variation testing is done to ensure uniformity in the weight of tablets, which is crucial for consistent dosage and efficacy.
- The USP (United States Pharmacopeia) method is widely used for determining weight variation in tablet testing.
Purpose of Weight Variation Testing
- The purpose of weight variation testing is to ensure that tablets have a uniform weight, which ensures consistent dosage and efficacy.
- It helps to identify any deviations in the manufacturing process that may affect the quality of the tablets.
Adjusting Weight Variation in Tablet Production
- In tablet production, weight variation is adjusted by adjusting the compression force, granulation, and formulation parameters.
- This adjustment ensures that the weight of the tablets falls within the acceptable limits.
Calculating Percentage Weight Variation
- The formula for calculating the percentage weight variation of tablets is: [(individual weight - average weight) / average weight] x 100.
- This formula helps to determine the deviation of individual tablet weights from the average weight.
Importance of Weight Variation Testing
- Weight variation testing is important to ensure that tablets meet the required quality standards.
- It helps to ensure public health and safety by ensuring that tablets have a uniform weight and consistency.
