 Europe/USA/Canada [Regulatives / Guidelines]

Dear All,

Request to clarify the below details,

If drug approved in the form Esomeprazole magnesium, not in the form of Esomeprazole Strontium, can we do the Bioequivalence study in Europe or Canada or USA in the form Esomeprazole Strontium?

What are the requirments needed for BE studies?

Regards,
AR_A

 Homework

Hi AR_A,

please do your homework first (see this post). Read the countries’ / regions’ relevant guidances / guidelines. Hint:
  • Same salt or ester: Pharmaceutical equivalent
  • Different salt or ester: Pharmaceutical alternative
E.g., FDA’s definition:

“Bioequivalence means the absence of a significant difference in the rate and extent to which the active ingredient or active moiety in pharmaceutical equivalents or pharmaceutical alternatives becomes available at the site of drug action when administered at the same molar dose under similar conditions in an appropriately designed study.”

if only they could discover enough facts about a problem,
these facts would somehow arrange themselves
in a compelling and true solution.    Theodosius Dobzhansky
