ABSTRACT:
Atrial peptides useful in practising the invention have the formula: ##STR1## wherein R.sub.1 is Arg, Leu-Arg, Ser-Leu-Arg, Arg-Ser-Leu-Arg, Pro-Arg-Ser-Leu-Arg, Gly-Pro-Arg-Ser-Leu-Arg, Ala-Gly-Pro-Arg-Ser-Leu-Arg or Leu-Ala-Gly-Pro-Arg-Ser-Leu-Arg; R.sub.17 is Met or Ile, R.sub.31 is Phe or desR.sub.31 ; R.sub.32 is Arg or desR.sub.32 ; R.sub.33 is Tyr or desR.sub.33 ; and Y is OH or NH.sub.2. These peptides or pharmaceutically acceptable salts thereof, dispersed in a pharmaceutically acceptable liquid or solid carrier, can be administered to mammals, particularly humans, in order to inhibit basal aldosterone secretion and/or to manage aldosterone-dependent hypertention.
