OBJECTIVE: To evaluate the effects of Tiangou Jiangya capsule on blood pressure and hemodynamics in anesthetized Beagle dogs.
METHOD: Anesthetized dogs were divided into five groups: Tiangou Jiangya capsule 3-dose groups as 1.6, 3.2, 6.4 g x kg(-1), positive control group was giving captopril, negative control was giving 0.5% CMC-Na, duodenal administration. The blood pressure and hemodynamic changes were observed.
RESULT: The systolic blood pressure of middle-dose Tiangou Jiangya capsule group was significantly reduced at 30 min after administration. The systolic blood pressure (SAP) and diastolic blood pressure (DAP) of high-dose group of Tiangou Jiangya capsule was significantly reduced at 15 min to 90 min after administration. High-dose Tiangou Jiangya capsule can also significantly reduce cardiac work (LVW) and total peripheral resistance (TPR). Tiangou Jiangya capsule had no significant effect on the other hemodynamic parameters and myocardial oxygen consumption.
CONCLUSION: Tiangou Jiangya capsule has a significant effect on reducing blood pressure, which is related to the reducing total peripheral resistance and reducing cardiac work. The result can provide a reference to further clarify the Tiangou Jiangya capsule mechanism on reducing blood pressure.
