Thyrotropin-Releasing Hormone Improves Cardiovascular Function in Experimental Endotoxic and Hemorrhagic Shock

Abstract
Thyrotropin-releasing hormone significantly improved cardiovascular function when it was injected intravenously into conscious rats subjected to experimental endotoxic or hemorrhagic shock. Because thyrotropin-releasing hormone appears to be a "physiologic: opiate antagonist without effects on pain responsiveness, it may provide therapeutic benefits in the treatment of shock or acute hypotension.
