| insulin injection | A preparation that may contain 20, 40, 80, 100, or 500 USP insulin units per ml, although the trend is toward standardizing all insulin preparations at 100 units per ml; it is administered subcutaneously, occasionally intravenously, and has a rapid onset of action, has a brief duration (5 to 7 hours), and is compatible for mixing with long-acting insulin preparations; used in the treatment of diabetic acidosis and insulin coma. Synonym: regular insulin injection. (05 Mar 2000) |
