A 60-year-old male with a history of alcoholic cirrhosis presents with massive hematemesis. Initial management includes establishing two large-bore IVs, fluid resuscitation, and ordering packed red blood cells. In addition to these measures, what is the most critical initial pharmacological intervention to manage suspected variceal hemorrhage?
