When the defence response of the body to infectious bacteria fails, septic
shock ensues with hypotension and death. RPPGF, (1-5)-bradykinin, was until
recently considered to be an inactive metabolite of bradykinin. in an anim
al model of septicaemia (lipopolysaccharide administration to rats), RPPGF
is protective, and can even prolong life. RPPGF, or stable mimetics, have p
otential in the treatment of septic shock.
