Revised Ph. Eur. Chapters 2.9.42 and 2.9.43 on Dissolution Testing

In Pharmeuropa, the “Comments concerning texts published in Issue 12.3” have been published. This provides the explanations relating to the new, revised and corrected texts adopted by the European Pharmacopoeia Commission. These include two chapters on dissolution testing:

• 2.9.42. Dissolution test for lipophilic solid dosage forms
• 2.9.43. Apparent dissolution

Both texts were previously published for comment in Pharmeuropa Issue 36.3. Further information on the changes can also be found in the PDF document published in Pharmeuropa.

The new texts will be published in Edition 12.3 of the European Pharmacopoeia in January 2026 and will be effective from 1 July 2026.
