European Pharmacopoeia -ph. Eur.- Monograph Tablets -0478- — !!install!!
The section of the monograph outlines crucial requirements for the manufacturing process. It mandates that tablets possess a suitable mechanical strength to avoid crumbling or breaking during handling and subsequent processing. This can be demonstrated using tests described in general chapters 2.9.7. Friability of uncoated tablets and 2.9.8. Resistance to crushing of tablets . Furthermore, the monograph requires suitable measures to be taken during manufacture, packaging, storage, and distribution to ensure the microbiological quality of the tablets, referencing general chapter 5.1.4. Microbiological quality of non-sterile pharmaceutical preparations and substances for pharmaceutical use .
This guide provides a structured interpretation of the monograph’s requirements, covering definitions, production, testing, and acceptance criteria.
Enteric-coated, prolonged-release, effervescent, sublingual, or chewable tablets – they have their own specific monographs.
Ph. Eur. 0478 covers solid preparations each containing a single dose of one or more active substances. While it primarily addresses oral tablets, it excludes certain forms like lozenges or oral pastes, which have their own specific standards. Key Quality & Performance Tests European Pharmacopoeia -ph.

The establishes the legally binding quality, safety, and manufacturing standards for oral tablet dosage forms across 39 European countries. Managed by the European Directorate for the Quality of Medicines & HealthCare (EDQM) , this general monograph serves as a regulatory cornerstone for pharmaceutical manufacturers, national control laboratories, and regulatory authorities. It guarantees that all tablets sold or distributed within the signatory states maintain rigorous and consistent chemical, physical, and microbiological properties. 1. Scope and Core Definition
When tablets feature a break-mark (notch) intended for partial dosing, the splitting precision must be verified.
The establishes the legally binding European Pharmacopoeia quality standards for manufacturing, testing, and distributing oral solid dosage forms. Maintained by the European Directorate for the Quality of Medicines & HealthCare (EDQM) , this general text dictates the legal and scientific benchmarks that any pharmaceutical product marketed within the signatory states must satisfy. The section of the monograph outlines crucial requirements
Gastro-resistant tablets must withstand an acidic medium (0.1 M HCl) for without breaking down, and then disintegrate in a phosphate buffer (pH 6.8) within 60 minutes . 2. Dissolution (Ph. Eur. 2.9.3)
If a tablet has a "break-mark" (score line) intended for delivering fractional doses, the efficacy of this mark must be validated.
Designed to resist gastric fluid for 2–3 hours but disintegrate in intestinal fluid within 60 minutes. Friability of uncoated tablets and 2
: Formulated to be easily crushed by chewing before swallowing, avoiding the immediate need for a disintegration test. Key Technical and Analytical Requirements
A significant portion of the monograph is dedicated to the . Many tablets bear break marks (or break-marks) to allow them to be split, either to ease intake or to deliver fractional doses. However, the monograph makes a crucial distinction:
