Reference Listed Drugs
Reference Listed Drug (RLD) is an approved drug product to which new
generic versions are compared to show that they are bioequivalent. A
drug company seeking approval to market a generic equivalent must
refer to the Reference Listed Drug in its regulatory submissions. Tosun
can source and supply RLD’s as required (specific batches & expiries) on
an international scale.
We can source innovator samples from different global markets. Our
experience with cold chain shipping and in dealing with international
customs requirements helps us to ensure that temperature-sensitive
study drugs arrive at your clinical trial facilities within the required
temperature range. We use dedicated transport companies that cater
to cold, ambient, and everyday storage and delivery requirements.
