Objective:To explore the absorption mechanism of Paeonol from various intestinal segments and offer biophamaceutics data for Paeonol new dosage form.Method:The absorption kinetics and permeability rate constants were investigated by the in situ perfusing method in rats.Result:The absorption rate in rats was descend as the order of jejunum、ileum、duodenum and colon.The absorption of the drug conforms to the first-order kinetics and passive transport machanism.Conclusion:The results indicate that Paeonol can be formulated and prepared as sustained release dosage form.
