Applicable Symptoms: 1. It can help increasing blood pressure to treat hypotension during general anesthesia and prevent arrhythmia; and it can also be used to treat hypotension induced by intraspinal block, but with the possibility of reducing cardiac output. 2. It can be used to terminate the onset of paroxysmal supraventricular tachycardia.

Applicable Symptoms: Indicated for shock syndrome caused by myocardial infarction, trauma, endotoxin sepsis, cardiac surgery, renal failure, and congestive heart failure; and for shock events that cannot be rescued by blood volume supplementation, especially for those with oliguria and normal or low peripheral vascular resistance. Since this product can increase cardiac blood output, it is also used for cardiac insufficiency where foxglove and diuretics are ineffective.

Applicable Symptoms: It is mainly indicated for severe dyspnea caused by bronchospasm. It can quickly relieve anaphylactic shock caused by drugs, and can also prolong the action time of infiltration anesthetics. It is the primary rescue drug in cardiopulmonary resuscitation for cardiac arrest caused by various reasons.

Applicable Symptoms: Indicated for blood pressure control in certain acute hypotensive situations (e.g., pheochromocytoma resection, sympathectomy, poliomyelitis, spinal anesthesia, myocardial infarction, sepsis, blood transfusion, and drug adverse reactions). Used as an adjuvant therapy for cardiac arrest and severe hypotension. For the emergency treatment of hypovolemia-induced shock, this product can be used as an adjuvant therapy to achieve blood volume supplementation, so as to help increase blood pressure and temporarily maintain perfusion in cerebral and coronary arteries until the blood volume supplementation takes effect; it can also be used for maintaining blood pressure after cardiopulmonary resuscitation (CPR).
