1 Hydralazine increased the serum renin levels from 3.3 +/- 0.5 to 13.7 +/- 3.1 and 41.9 +/- 2.4 ng/ml/hr at the 1 and 10 mg/kg doses, respectively. Hydralazine renin Rattus norvegicus
2 Inhibition of hydralazine-induced renin release by indomethacin in the rat. Hydralazine renin Rattus norvegicus
3 Since the vasodilator hydralazine is thought to stimulate renin release by both of these mechanisms, we examined the effect of indomethacin, a PG synthetase inhibitor, on hydralazine-induced renin release. Hydralazine renin Rattus norvegicus
4 Since the vasodilator hydralazine is thought to stimulate renin release by both of these mechanisms, we examined the effect of indomethacin, a PG synthetase inhibitor, on hydralazine-induced renin release. Hydralazine renin Rattus norvegicus
5 Indomethacin inhibited this hydralazine-induced renin release by 100% at the 1 mg/kg dose and 36% at the 10 mg/kg dose even though the hypotensive effect of the drug was unaltered. Hydralazine renin Rattus norvegicus
6 The beta-blocker, propranolol, was as effective as indomethacin in attenuating hydralazine-induced renin release. Hydralazine renin Rattus norvegicus
7 Thus, renal PG"s appear to be important as mediators of hydralazine-stimulated renin release but no hydralazine-induced vasodilatation. Hydralazine renin Rattus norvegicus
