Intended to be dissolved or dispersed in water before administration.
The monograph applies to solid preparations containing a single dose of one or more active substances, obtained by compressing uniform volumes of particles or by alternative techniques such as extrusion, moulding, or freeze-drying (lyophilisation).
Patient safety relies on dose-to-dose uniformity. Monograph 0478 mandates strict adherence to analytical parameters that prevent hazardous dosing variations: european pharmacopoeia ph eur monograph tablets 0478 better
Next came the physical endurance tests. Elias watched the tablets tumble inside the . To be "better" by Ph. Eur. standards, a tablet must be rugged enough to survive the high-speed packaging lines and the journey to a patient’s bedside without chipping (limiting weight loss to less than 1%).
The provides the general quality standards for tablets intended for oral administration. It covers a variety of types, including uncoated, coated, gastro-resistant, and modified-release tablets. Key Quality Requirements Intended to be dissolved or dispersed in water
The sterile, hum of the quality control lab was broken only by the rhythmic clicking of the dissolution tester. Elias, a senior analytical chemist, stared at the latest batch of . They met the basic release criteria, but "basic" wasn’t the goal today. His team was tasked with aligning their process with the rigorous standards of European Pharmacopoeia (Ph. Eur.) Monograph 0478 .

For orodispersible tablets, 0478 specifies a specific disintegration medium (usually water at 15–25°C). Using a buffer can artificially speed up disintegration, leading to a false pass.

Mandatory for tablets with active ingredient content below a specific threshold (typically less than 2 mg or less than 2% of the total mass), requiring individual assay of a randomized batch sample. Dissolution Testing (2.9.3)
In such cases, the applicant may either select the monograph's disintegration test or develop an as a product-specific test. The key is that the chosen test's suitability must be demonstrated to the satisfaction of the competent authority. This approach aligns with the ICH Q6A guideline on specifications, balancing the need for rigorous control with scientific flexibility. The principles applied to disintegration tests mirror those outlined for dissolution testing in the Ph. Eur. General Notices.
