The "better" provides several benefits to stakeholders:
Simple matrices that release active substances without delayed barrier coatings.
The revised monograph 0478, bolstered by the 2020 EDQM policy, clarifies the mandate for dissolution testing in immediate-release formulations.
The monograph provides the general requirements for all immediate-release tablets, including definitions, production requirements, and testing criteria. It covers aspects such as: Uniformity of mass Uniformity of content Dissolution/Disintegration rates Subdivision (break-marks) european pharmacopoeia ph eur monograph tablets 0478 better
Disintegrate in the mouth within 3 minutes.
In the stringent world of pharmaceutical manufacturing, ensuring the quality, safety, and efficacy of tablet formulations is paramount. The European Pharmacopoeia (Ph. Eur.) provides the definitive standards for these, with acting as the foundation for oral solid dosage forms.
A product-specific dissolution test is mandatory for most immediate-release solid dosage forms to ensure batch-to-batch consistency. 2. Subdivision of Scored Tablets It covers aspects such as: Uniformity of mass
The sets the essential quality and manufacturing standards for Tablets (Compressi) . This general monograph applies to all tablets unless a specific product monograph states otherwise, providing the legal and scientific basis for their quality control in Europe.
Friability tests the tablet’s resistance to chipping, abrasion, or breaking under mechanical stress during handling and transportation. The standard acceptance criterion for compressed, uncoated tablets is .
Before the creation of the European Pharmacopoeia, each European country maintained its own national standards for medicines. A tablet approved in France might not meet the quality requirements in Germany or the UK, leading to trade barriers and potential safety gaps. The Convention on the Elaboration of a European Pharmacopoeia (1964) sought to eliminate these discrepancies. Monograph 0478, first published in the late 20th century and regularly updated, represents the culmination of this harmonisation effort. It aligns with the work of the International Council for Harmonisation (ICH) and the Pharmacopoeial Discussion Group (PDG), ensuring that the quality tests for tablets are consistent not only across Europe but also with the Japanese and United States pharmacopoeias where possible. This harmonisation makes the standard “better” by removing ambiguity for manufacturers and regulators. ” Elara said
“Monograph 0478 specifies 75 rpm,” Elara said, her voice quiet but hard as granite. “If we change it, we are no longer complying with the Ph. Eur. The data would be meaningless.”
This test (Ph. Eur. general chapter ) ensures that a batch of tablets contains consistent individual masses. According to 0478 , if a uniformity of content test is required for all active substances—based on criteria in the general monograph—then the uniformity of mass test may be omitted.
