Activity

  • Function:  Induces smooth muscle dilation and contraction. Intra-arterial injection induces a significant decrease in ventral aortic blood pressure of between 5 and 10 minutes duration followed by a dose dependent increase in ventral aortic blood pressure of between 30 and 60 minutes duration. May target bradykinin receptors (BDKRB).
