Friability testing is primarily associated with which dosage form?

• A. Capsules
• B. Tablets
• C. Powders
• D. Solutions

Answer: (B)

Friability testing assesses how well a solid dosage form resists abrasion and breakage when subjected to handling and packaging stresses. The test uses a friabilator to tumble tablets and then measures any weight loss to gauge their tendency to crumble. This concept is most relevant for tablets because they are compacted solids that must survive grinding, rubbing, and vibration during manufacturing, packaging, shipping, and dispensing without crumbling or breaking. Powders, solutions, and capsules don’t face the same kind of uniform abrasive impact in the same way tablets do, so the standard friability test is not the primary quality check for those forms. In practice, tablets are the dosage form routinely evaluated for friability to ensure they maintain integrity and accurate dosage under normal handling.
