Monograph 0478 mandates several critical tests to ensure batch-to-batch consistency:
: This test determines whether tablets break up within a prescribed time when placed in a liquid medium. For plain tablets, the standard limit is typically 30 minutes in water at
Historically, dissolution testing parameters could vary between individual product monographs and the general monograph. This led to the Ph. Eur. Commission surveying users in January 2019 regarding three options: retaining a mandatory dissolution test, making it an example, or relying on the general monograph. A compromise was reached in November 2020: a dissolution or disintegration test will be included in each individual product monograph. The specific details and conditions for use are outlined in the of the Ph. Eur. European Pharmacopoeia -ph. Eur.- Monograph Tablets -0478-
Monograph defines tablets as solid pharmaceutical dosage forms containing a single dose of one or more active substances. They are typically obtained by compressing uniform volumes of particles and are intended for oral administration, though some sub-types may be intended for other routes. Core Quality Requirements
| Requirement | Details | | :--- | :--- | | | Tablets must be robust enough for handling and subsequent processing. This is assessed through tests like Friability of uncoated tablets (2.9.7) and Resistance to crushing of tablets (2.9.8) . | | Uniformity of Subdivided Parts (for Scored Tablets) | For tablets with break-marks used to split doses, the manufacturer must demonstrate that the subdivided parts are uniform. The test involves breaking 30 tablets, weighing one half from each, and ensuring no more than one mass falls outside 85-115% of the average mass. | | Microbiological Quality | Suitable measures must be taken to ensure microbiological quality throughout the lifecycle, in line with general chapter 5.1.4. | Monograph 0478 mandates several critical tests to ensure
The European Pharmacopoeia (Ph. Eur.) is a publication that contains a set of monographs and general chapters that describe the official standards for medicines in Europe. The Ph. Eur. is published by the European Directorate for the Quality of Medicines & Healthcare (EDQM), which is a part of the Council of Europe. The Ph. Eur. is recognized as a standard for the quality of medicines in many countries, including all European Union member states.
The monograph specifies the test methods that must be used to evaluate tablets, including: The specific details and conditions for use are
Monograph 0478 also provides additional requirements for specialized tablet types:
