Abstract:
AIM To study the effect l-menthol pretreated nasal cavity on insulin pharmacological bioavailability(PBA). METHODS To set up diabetic rats model,nasal cavities were pretreated with l-menthol for two hours,insulin was dripped, blood glucose concentrations of different time were determined,and the area over the curve (AOC) and pharmacological bioavailability(PBA) were calculated. RESULTS After rats nasal cavity was pretreated with different concentrations l-menthol, nasal cavity absorption of insulin markedly increased between 2 h and 3 h,and PBA of insulin nasal cavity absorption increased respectively 5.77,7.00 and 3.12 times than control group. CONCLUSION l-Menthol promotes the nasal cavity absorption of insulin.
