EMA releases reflection paper for generic oral immediate release products

Home/Guidelines | Posted 20/05/2016 post-comment0 Post your comment

The European Medicines Agency (EMA) announced on 13 May 2016 the publication of draft guidance on the dissolution requirements for orally administered generics with immediate release characteristics.

09 AA008582

The draft reflection paper defines immediate release as a product where at least 75% of the active substance is dissolved within 45 minutes. This derives from the Ph. Eur. (5.17.1) recommendation for conventional release dosage forms.

The paper discusses the suitability of the dissolution method and the specifications for in vitro dissolution of orally administered generics with immediate release characteristics. It is intended to ensure batch-to-batch consistency and, ideally, signal potential problems with in vivo bioavailability. It should also be read in connection with the principles of relevant guidelines.

The reflection paper does not, however, discuss the dissolution tests in three different buffers required as complementary to bioequivalence studies.

EMA has released the draft reflection paper for a three-month public consultation period. Feedback on the draft reflection paper can be submitted to EMA until 13 August 2016. Comments should be submitted to QWP@ema.europa.eu using the template provided by EMA.
