Introduction to Tablet Hardness Testing
In pharmaceutical manufacturing, the process of making tablets involves compressing either powders or granules into a single form (tablet). The strength of the tablets mechanically is the most important quality measure for a tablet. The testing of tablet hardness provides a quantitative measurement of the mechanical strength of a tablet and therefore provides a direct measurement of the tablets’ structural integrity. The structural integrity of a tablet has implications for downstream processes and for patient health: e.g., if a tablet is manufactured too soft, it may break up through the packaging/shipping process; if too hard, it might resist disintegration, negatively affecting tablet dissolution testing and drug absorption.
Establishing the relationship between compression force applied, tablet durability, and drug release would be the essence of a robust quality control program for maximizing the quality of manufactured tablets.
What is a Tablet Hardness Tester
A tablet hardness tester is a specialized analytical instrument used in pharmaceutical laboratories to measure the breaking force of a tablet. It functions as a tablet compression strength tester, or tablet compression strength tester Quebec and a tablet breaking force tester Quebec applying a controlled, increasing mechanical load until the tablet fractures. Tablet hardness testers are specific analytical instruments found in pharmaceutical laboratories that measure the breaking force of tablets. Tablet hardness testers work by measuring the breaking force using a controlled, increasing mechanical load until the tablet breaks.
Definition of Tablet Breaking Force
The tablet breaking force is the mechanical force required to fracture a compressed tablet under diametrical compression. This force is expressed in Newtons (N), the standard SI unit.
Importance in Pharmaceutical Quality Control
In quality control of the pharmaceutical industry, hardness testing is performed to verify that the hardness of the tablet conforms to specification for every batch manufactured. Tablet hardness testing is used to verify the:
Durability: will the tablet withstand the stress of the coating, the stress of packaging and the stress of shipping?
Dosage Consistency: is the compaction pressure for every individual tablet the same in order to produce the same dosage?
Dissolution: does the active ingredient dissolve properly?
H2 Standard Hardness Range for Pharmaceutical Tablets
The breaking force of most bare tablets falls between 40 and 100 Newton (N). The standard hardness range for pharmaceutical tablets is established during the development stage to ensure that there is an adequate mechanical integrity and dissolution performance. The target hardness is established based on:
- The composition of the formulation
- The pressure applied during compression
- The size and thickness of the tablets.
Factors Affecting Tablet Hardness
The compression pressure is the major determining factor of a tablet’s final hardness. A higher pressure will produce more bonding. The concentration of the binder that is used will also affect the strength of the tablet. Smaller, uniform granules will yield a harder tablet than large, non-uniform granules. Too much or too little moisture will also adversely affect compressibility.
Units Used in Tablet Hardness Testing
Consistent measurement units are crucial for data transfer between R&D and QC.
Newton (N)
The SI unit for force is the Newton, and it is used in engineering as it provides the most accurate values for the force that is exerted on an object.
Kilogram Force (kgf)
Some older machines use kilograms-force (kgf), where 1 kgf equals the force applied to a mass of 1 kilogram due to the force of gravity acting on it.
Kilopond (kp)
The kilopond is a historical unit equivalent to the kilogram‑force, still referenced in older testing manuals. What unit measures tablet hardness? In modern pharmaceutical quality control, the Newton (N) is the standard.
How Tablet Hardness Testing Works
A newly designed tablet hardness testing machine operates through a precise sequence.
Tablet Placement
Tablets are placed on an automated platform. Advanced systems provide for automated loading of tablets into the test platform to reduce variability.
Force Application
A precision motor applies diametrical compression at a constant, predefined speed.
Breaking Force Detection
High-precision load cells record the exact force required to break a tablet, as well as the maximum force prior to breakage. The record of these results is electronically stored and displayed, allowing for secure data management (i.e., batch documentation).
Digital Data Recording
Results are displayed and electronically stored, supporting secure data management for batch documentation.
Importance of Tablet Hardness Testing in Pharmaceutical Manufacturing
Tablet hardness testing is essential for both quality control testing of medicines and quality control in the manufacture of tablets. Tablet hardness testing helps ensure the following:
- The mechanical stability of the tablet when coated and packaged.
- The durability of any tablets shipped or handled without generating fines (small particles).
- Dissolution profile of the tablets based upon whether a tablet meets specifications for disintegration and drug release.
- Real-time monitoring of the compression process to ensure consistency from batch to batch.
