 bioequivalence of drug combination [Regulatives / Guidelines]

Hello
I need your advice please regarding this :
if ever a drug combination (like candesartan hydrochlorothiazide) has demonstrated its BE with the princeps,
is it mandatory to perform study for candasertan alone (same pharmaceutical company, same dosage)

Thanks !

Hi, Norah!

» (same pharmaceutical company, same dosage)

What about excipients? The same quality and quantity?

Best regards

 bioequivalence of drug combination

Hello Norah,
As per USFDA, it is mandatory to perform separate studies for separate products.
FDA will not accept plain candesartan ANDA without BE studies.
Moreover, candesartan a BCS class II product and waiver approach (based on combination product BE study) is not possible to get the waiver for plain Candesartan.
