Although serotonin may be responsible for the diarrhea of the carcinoid syndrome, recent evidence suggests that bradykinen induces the flushes and the vascular phenomena. A rise in hepatic venous bradykinen concentration accompanying flushing has been demonstrated, and a specific kallikrein has been isolated from carcinoid cells. Catecholamines can induce flushing attacks. Since intravenous epinephrine is more effective than norepinephrine in this regard and since alpha-adrenergic blocking agents are ineffective in carcinoid patients, a study of the effect of beta blockade in the carcinoid syndrome seemed warranted. Studies were made in four patients with metastatic carcinoid from primary ileal carcinoids.
