Summary
CTD was introduced with the aim to harmonize submission of
technical data for registration of human use in different
regions.
After 5 years of implementation of ctd,we can say that
considerable harmonization has been achieved in various
regions for submission of technical data.
More and more regulatory agencies have started association
with this implementation generated actually by ICH before 5
years back.
