Effects of selective and non-selective beta 1-blockade on renin secretion in the isolated rat kidney

Abstract
The participation of beta 1-adrenoceptor on renin secretion was studied in perfused rat kidney.Administration of propranolol, inhibited the renin release mediated by isoproterenol.Likewise, metoprolol and practolol, showed a similar potency to propranolol in inhibiting isoproterenol-induced renin secretion.These results suggest that the for isoproterenol-induced renin release in rats is a beta 1-type adrenoceptor.
