Thai FDA suggest that the time points should be more than 3 points of the Dissolution profile in part of Pharmaceutical development have been your provided as attached files.
Response:
We have noted the agency’s comment.
In-vitro dissolution time point recommendation in guidance:
• A minimum of three points should be proposed in the setting the specification on in vitro dissolution for prolonged release product.
We would like to bring into the agency consideration that
• It is sufficient to perform the in-vitro dissolution study with the proposed in-vitro dissolution specification time point for various development trials in Pharmaceutical development section.
• The appropriate comparative dissolution profile has been generated with greater number of time points for complementary to bioequivalence study and in support of biowaiver in accordance with bio-equivalence guidance in Pharmaceutical development section.
Based on above discussion, we are of opinion that the in-vitro dissolution study data presented in pharmaceutical sections is in accordance with the guidance recommendation.
