Study Notes
- Friability testing of tablets is conducted using a plastic chamber that revolves at 25 rpm, causing tablets to experience abrasion and shock
- After 4 minutes, the tablets are weighed to determine percentage loss, or friability, which must be less than or equal to 1%
- Friability testing applies to most tablets, but some chewable and effervescent tablets require special packaging due to their high friability
- A shipping test method is used to evaluate a product's ability to withstand transportation and handling
- Official standards, such as the British Pharmacopoeia (B.P.) and US Pharmacopoeia (USP), provide tests and specifications for tablets
- A tablet's uniformity of dosage form is tested through weight and content uniformity, which indicate the consistency of active ingredients and tablet weight for a given batch
- For compressed uncoated tablets, testing fluid is water at 37°C, while coated tablets and some others require longer test times
- Tests for weight and content uniformity involve weighing and comparing individual tablets, and the USP sets a limit of 5% for content uniformity variation
- British Pharmacopoeia test design for weight uniformity requires that none of the 20 tablets deviate from the average weight by more than double the % deviation, and no more than two tablets can deviate by more than the % deviation.
