European Pharmacopoeia -ph. Eur.- Monograph Tablets -0478- !new! Official

Ph. Eur. 2.9.6 (or 2.9.40) If a tablet contains less than 2 mg or less than 2% (w/w) of an active substance, Uniformity of Mass is not sufficient . You must perform Uniformity of Content via an assay (usually HPLC) on 10 individual tablets.

: Active components are blended with diluents, binders, disintegrating agents, glidants, lubricants, coloring agents, or flavoring agents to ensure structural integrity and stability. Categories of Oral Tablets

This monograph does not apply to lozenges, oral pastes, or oral gums, which are covered under other sections like Oromucosal Preparations (1807) . Primary Tablet Categories

: It does not naturally apply to lozenges, oral pastes, oral gums, or tablets modified for alternate cavities. Separate general monographs regulate those specific pathways, such as Rectal Preparations (1145) , Vaginal Preparations (1164) , and Oromucosal Preparations (1807) . 2. Production and Mechanical Strength Requirements European Pharmacopoeia -ph. Eur.- Monograph Tablets -0478-

The active substance(s) must be identified using the tests prescribed in the specific monograph for that substance (e.g., spectroscopy, chromatography).

The label must clearly state:

For sugar-coated tablets, use the core mass; for film-coated, use the total mass. You must perform Uniformity of Content via an

In the world of modern medicine, the tablet is the undisputed king. It is the default delivery system for the vast majority of active pharmaceutical ingredients (APIs). Yet, behind every unassuming white disc lies a complex engineering challenge: how do you ensure that a powder becomes a solid, survives the journey in a bottle, and then dissolves perfectly inside the human body?

A 2020 European study found many tablets failed Ph. Eur. divisibility requirements. The Freedom of Information request regarding UK liothyronine tablets further demonstrates the practical consequences of non-compliance with these rules.

The "Tablets -0478-" monograph describes various test methods that can be used to evaluate the quality of tablets, including: Primary Tablet Categories : It does not naturally

Monograph 0478 explicitly differentiates distinct categories of oral tablets based on their design, protective layers, and drug-release kinetics:

: Tablets designed to disperse rapidly in the mouth or dissolve in water before administration. 3. Production and Quality Control Requirements

Weighing individual tablets to ensure they fall within strict percentage deviations.

Monograph 0478 begins by defining precisely what constitutes a "tablet." According to the Ph. Eur., tablets are solid dosage forms containing one or more active substances, with or without excipients, obtained by compressing uniform volumes of particles. The monograph explicitly covers a wide range of tablet types, including uncoated, film-coated, gastro-resistant (enteric-coated), and dispersible tablets. Importantly, it also addresses sublingual, buccal, and effervescent tablets, highlighting the versatility of the dosage form.
