Dear Divyen

❝ ❝ ❝ they given the reference of following of guidance documents of Europe:: Guideline for locally applied , locally acting product in Gestrointestinal trac(CPMP/EWP/239/95Rev.1,Cor.1*) and this guidance documents given the acceptance limit as +- 10percentage..

❝

❝ Read the sentence again: In vitro similarity should be assessed with a ±10% acceptance range, unless otherwise justified.

we were already given justification based on this sentence.and explain that our study is passing within T/R ratio as per acceptance limit 0.9 to 1.1...but they are not accepting the same and again raised the queries....so now we are repeating the same study ,.
