Aramine (levo l-(m-hydroxyphenyl)-2-amino-l-propanol) was used in over 250 unselected cases of shock of varied etiology, of which 42 cases are reported in some detail. Uniformly good results were noted, and Aramine is preferred to other vasopressor drugs. This agent continues to produce a vasopressor effect after the actual cessation of administration, and its use is characterized by ease in maintaining the desired blood pressure level. In contradistinction to other vasopressor agents, distressing side effects, such as arrhythmia, thrombophlebitis, or tissue slough, do not occur.
