Rates of benzydamine N - oxygenation ( catalyzed by FMO3 ) varied ( approximately 20 - fold ) among the 28 cynomolgus livers and were significantly correlated with FMO3 protein expression , indicating that the inter - animal variations in benzydamine N - oxygenation might be partly accounted for by the variable FMO3 expression .
