Tablet Hardness and Friability Testing: Safeguarding Drug Stability from Lab to Market

In the manufacturing and distribution of tablets, ODFs, and functional supplements, mechanical stability is a critical quality parameter. Excessive hardness can hinder disintegration, while high friability can cause breakage during packaging or transport—compromising both appearance and dosage accuracy.

Why Are Hardness and Friability Tests So Important?

• Regulatory Compliance: Pharmacopeias such as USP, EP, and ChP all mandate standardized hardness and friability testing protocols.
• Logistics & Storage Integrity: Inadequate mechanical strength leads to breakage during handling, increasing wastage rates.
• Dose Uniformity: Poor friability may result in tablet powdering, affecting the consistency of active ingredients.

Common Challenges Faced by Manufacturers

• Testing only hardness, neglecting friability across batch samples.
• Inaccurate readings due to low-precision instruments or unstable rotation speeds.
• Infrequent quality control checks post-R&D, exposing production batches to potential risks.

Trends Driving the Industry Forward

• Integrated instruments combining hardness, friability, weight, and thickness measurements.
• Automated sampling modules to ensure repeatability and reduce human error.
• Enhanced sensitivity to accommodate mini-tablets and emerging dosage formats.
