Pentoxifylline treatment enhances antihypertensive activity of captopril through hemorheological improvement in spontaneously hypertensive rats during development of arterial hypertension
The rheological properties of blood play a significant role in the onset and progression of arterial hypertension. The aim of our work was to evaluate the effect of the angiotensin-converting enzyme inhibitor captopril (20 mg/kg/d), pentoxifylline (PTX; 100 mg/kg/d), and the combination of captopril...

520 | |a The rheological properties of blood play a significant role in the onset and progression of arterial hypertension. The aim of our work was to evaluate the effect of the angiotensin-converting enzyme inhibitor captopril (20 mg/kg/d), pentoxifylline (PTX; 100 mg/kg/d), and the combination of captopril + PTX (20 + 100 mg/kg/d) on the hemodynamic and hemorheological parameters in spontaneously hypertensive rats (SHRs) during the development of arterial hypertension. In the group of animals that received captopril, the mean arterial pressure (MAP) was significantly lower by 30% due to a decrease in cardiac output of 23% and in total peripheral resistance (TPR) of 26% compared with the control group, whereas blood viscosity did not change significantly. PTX-treated SHRs had significantly lower MAP and TPR (by 19% and 31%, respectively) and blood viscosity (by 4%–6%) and a higher erythrocyte deformability index (by 1.5%–2%) than the control group. In the group of animals that received captopril + PTX, MAP and TPR were significantly lower, by 41% and 46%, than those in the control group, and by 16% and 27% than those in the captopril group. The combination of the angiotensin-converting enzyme inhibitor captopril and the hemorheological agent PTX, affecting various systems that are involved in blood pressure regulation, exhibits synergism and prevents an increase in arterial blood pressure during the development of arterial hypertension in SHRs (ie, from 5 to 11 weeks of life). | ||

The combination of the angiotensin-converting enzyme inhibitor captopril and the hemorheological agent PTX, affecting various systems that are involved in blood pressure regulation, exhibits synergism and prevents an increase in arterial blood pressure during the development of arterial hypertension in SHRs (ie, from 5 to 11 weeks of life). The rheological properties of blood play a significant role in the onset and progression of arterial hypertension. The aim of our work was to evaluate the effect of the angiotensin-converting enzyme inhibitor captopril (20 mg/kg/d), pentoxifylline (PTX; 100 mg/kg/d), and the combination of captopril + PTX (20 + 100 mg/kg/d) on the hemodynamic and hemorheological parameters in spontaneously hypertensive rats (SHRs) during the development of arterial hypertension. In the group of animals that received captopril, the mean arterial pressure (MAP) was significantly lower by 30% due to a decrease in cardiac output of 23% and in total peripheral resistance (TPR) of 26% compared with the control group, whereas blood viscosity did not change significantly. PTX-treated SHRs had significantly lower MAP and TPR (by 19% and 31%, respectively) and blood viscosity (by 4%–6%) and a higher erythrocyte deformability index (by 1.5%–2%) than the control group. In the group of animals that received captopril + PTX, MAP and TPR were significantly lower, by 41% and 46%, than those in the control group, and by 16% and 27% than those in the captopril group. The combination of the angiotensin-converting enzyme inhibitor captopril and the hemorheological agent PTX, affecting various systems that are involved in blood pressure regulation, exhibits synergism and prevents an increase in arterial blood pressure during the development of arterial hypertension in SHRs (ie, from 5 to 11 weeks of life).

abstract |
The rheological properties of blood play a significant role in the onset and progression of arterial hypertension. The aim of our work was to evaluate the effect of the angiotensin-converting enzyme inhibitor captopril (20 mg/kg/d), pentoxifylline (PTX; 100 mg/kg/d), and the combination of captopril + PTX (20 + 100 mg/kg/d) on the hemodynamic and hemorheological parameters in spontaneously hypertensive rats (SHRs) during the development of arterial hypertension. In the group of animals that received captopril, the mean arterial pressure (MAP) was significantly lower by 30% due to a decrease in cardiac output of 23% and in total peripheral resistance (TPR) of 26% compared with the control group, whereas blood viscosity did not change significantly. PTX-treated SHRs had significantly lower MAP and TPR (by 19% and 31%, respectively) and blood viscosity (by 4%–6%) and a higher erythrocyte deformability index (by 1.5%–2%) than the control group. In the group of animals that received captopril + PTX, MAP and TPR were significantly lower, by 41% and 46%, than those in the control group, and by 16% and 27% than those in the captopril group. The combination of the angiotensin-converting enzyme inhibitor captopril and the hemorheological agent PTX, affecting various systems that are involved in blood pressure regulation, exhibits synergism and prevents an increase in arterial blood pressure during the development of arterial hypertension in SHRs (ie, from 5 to 11 weeks of life). |

The aim of our work was to evaluate the effect of the angiotensin-converting enzyme inhibitor captopril (20 mg/kg/d), pentoxifylline (PTX; 100 mg/kg/d), and the combination of captopril + PTX (20 + 100 mg/kg/d) on the hemodynamic and hemorheological parameters in spontaneously hypertensive rats (SHRs) during the development of arterial hypertension. In the group of animals that received captopril, the mean arterial pressure (MAP) was significantly lower by 30% due to a decrease in cardiac output of 23% and in total peripheral resistance (TPR) of 26% compared with the control group, whereas blood viscosity did not change significantly. PTX-treated SHRs had significantly lower MAP and TPR (by 19% and 31%, respectively) and blood viscosity (by 4%–6%) and a higher erythrocyte deformability index (by 1.5%–2%) than the control group. In the group of animals that received captopril + PTX, MAP and TPR were significantly lower, by 41% and 46%, than those in the control group, and by 16% and 27% than those in the captopril group. The combination of the angiotensin-converting enzyme inhibitor captopril and the hemorheological agent PTX, affecting various systems that are involved in blood pressure regulation, exhibits synergism and prevents an increase in arterial blood pressure during the development of arterial hypertension in SHRs (ie, from 5 to 11 weeks of life).</subfield></datafield><datafield tag="520" ind1=" " ind2=" "><subfield code="a">The rheological properties of blood play a significant role in the onset and progression of arterial hypertension.
