Abstract:
Objective To study the nasal mucosa absorption of paeonol ofXingbi microemulsion-based thermo-sensitive gel in rats; To evaluate the nasal mucosa absorption of medicine and the rationality of preparation form.Methods According to the nasal administration method, the blood medicine concentration of paeonol was determined at different time points.Results The nasal administration bioavailability of paeonol in Xingbi microemulsion-based thermo-sensitive gel was 78.68%, the plasma concentration reached the maximum (0.3404 μg/mL) after 3 min of administration, and the average residence time was 9.23 h. After reaching Cmax, The plasma concentration changed similar to intravenous administration of paeonol. The concentration data of paeonol in plasma was consistent with a two-compartment model, with a weight of 1.Conclusion Xingbi microemulsion-based thermo- sensitive gel has a higher bioavailability, and the preparation form was reasonable.
