Abstract:
Objective:to study the absorption and absorption characteristics of isomer of propranolol hydrochloride in Caco-2cell monolayers model,which have taken as the most representative model to investigate the absorption mechanism of oral drug in recent years. Methods:Caco-2 cell monolayers model was set up to study transport of isomer of propranolol hydrochloride. RP-HPLC method was applied to analyze isomer of propranolol hydrochloride through precolumn derivatization. Results: Propranolol hydrochloride was absorbed completely,and was a passive diffusion mechanism. There was no chiral selectivity of transport and absorption of them across Caco-2 cell monolayers. Conclusion: Caco-2 cell model was established and the cell integrity was evaluated. The integrity of Caco-2 cell was in good condition,which could be used to study the absorption and transport. RP-HPLC method was established to separated isomer of propranolol hydrochloride within 20 min by precolumn derivatization. The method is convenient, sensitive,accurate and suitable for the analysis of telbivudine.
