Most manufacturers reference (Uniformity of Dosage Units) as part of the identification strategy, ensuring the correct label claim is present in the correct proportion.
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.
Before diving into testing, understanding the legal definition is crucial. According to Monograph 0478, a tablet is defined as: European Pharmacopoeia -ph. Eur.- Monograph Tablets -0478-
: This test determines whether tablets break down within a specified time when placed in a liquid medium, ensuring the drug will be available for absorption. Subdivision of Tablets (Break-marks)
The monograph divides tablets into several categories: Most manufacturers reference (Uniformity of Dosage Units) as
The monograph subdivides tablets into specific categories, each with tailored testing criteria:
: Uncoated tablets containing acid substances and carbonates that react quickly in water to release carbon dioxide. The monograph explicitly covers a wide range of
To ensure seamless passage of a Ph. Eur. audit (e.g., by a European OMCL – Official Medicines Control Laboratory), follow these protocols:
The Ph. Eur. actively works with other major pharmacopoeias (like the and Japanese Pharmacopoeia ) through the Pharmacopoeial Discussion Group (PDG) to harmonize standards wherever possible. This global harmonization is guided by principles such as those outlined in the ICH Q6A guideline on specifications, and it represents a continuous effort to align key tests like disintegration.
