(CTD vs eCTD Explained – Difference, Structure & Regulatory Submission Guide) |
INTRODUCTION
Regulatory Affairs field me kaam karne wale har professional ko CTD aur eCTD ka clear knowledge hona bahut jaruri hota hai. Jab bhi koi pharmaceutical company apni medicine ko US FDA, EMA ya kisi bhi global authority me submit karti hai, tab submission ka standard format CTD ya eCTD hota hai.
Aaj ke time me manual CTD ki jagah eCTD submission mandatory hota ja raha hai. Is article me hum simple language me samjhenge:
ABOUT THE CONCEPT
CTD ka full form Common Technical Document hai jo ICH (International Council for Harmonisation) ne banaya tha. My main purpose was to create a common format for worldwide regulatory submissions.
eCTD ka matlab hai Electronic Common Technical Document. Yah CTD ka digital version hai jisme XML backbone aur lifecycle management hota hai. Aaj, US, Europe, Canada jaise market mein eCTD compulsory ho chuka hai.
