Product Data:
Biological target: Oxolamine citrate (SKF-9976 citrate) is a cough suppressant.
In vitro activity: TBD
In vivo activity: After oral administration of warfarin at a dose of 2 mg/kg to male rats with oxolamine at doses of 10 and 50 mg/kg, the AUC values of warfarin were significantly greater than the controls (254 and 330 versus 180 microg h/ml). However, the AUC values of warfarin were not affected by oxolamine in female rats. This could be due to inhibition of CYP2B1, 2C11 and 3A2 by oxolamine in male rats, since warfarin was metabolized via CYP1A1, 2B1, 2C6, 2C11 and 3A2 in rats and CYP2B1 is male dominant, and CYP2C11 and 3A2 are male specific.
