The content of the active substance(s) must be determined. The assay verifies that the tablets contain the amount of drug claimed on the label within defined limits.
A soft tablet (low hardness) might disintegrate in 12 minutes, but a hard tablet (high compression force) might take 25 minutes, failing 0478. Formulators must balance hardness and disintegration.
: Determines the resistance of the tablet surface to abrasion and impact. A sample roll in a specialized drum must demonstrate that weight loss does not exceed strict limits. European Pharmacopoeia -ph. Eur.- Monograph Tablets -0478-
Monograph 0478 classifies tablets based on their release characteristics and site of action:
The majority of Monograph 0478 is dedicated to mandatory physical tests. Failure in any of these three categories results in batch rejection. The content of the active substance(s) must be determined
Must produce a smooth, uniform suspension that passes through a 710 µm sieve after disintegration. 5. Storage, Packaging, and Labeling
This article provides a detailed examination of the Tablets monograph, exploring its scope, key requirements, and critical updates, as well as its vital role in the global pharmaceutical regulatory framework. Formulators must balance hardness and disintegration
This article provides an in-depth analysis of Ph. Eur. Monograph 0478, exploring its scope, core quality requirements, critical testing methodologies, and its profound impact on pharmaceutical manufacturing and regulatory compliance. 1. Scope and Definition of Monograph 0478
Under Monograph 0478, tablets are defined as They are obtained by compressing uniform volumes of particles or by other methods of manufacture (e.g., moulding, extrusion).
