Angiotensin II Brings More Questions Than Answers

摘要

The approval of synthetic human angiotensin II (Giapreza, LaJolla Pharmaceuticals) by the FDA in December 2017 provides clinicians with a new tool in the treatment of distributive shock. Angiotensin II (ATII) was approved based on the results of the ATHOS-3 trial. In this trial, patients who received angiotensin II were more likely to achieve a mean arterial pressure of 75 mmHg or an increase in mean arterial pressure of 10 mmHg above that seen in patients who received a placebo. However, the results of ATHOS-3 also highlighted important concerns about thrombotic and infectious complications associated with ATII. Given that the cost of medication acquisition is approximately $1,500 per vial, practitioners must also decide how to implement ATII into practice in the most cost-effective manner. This commentary examines the current controversies surrounding both the safety and efficacy of ATII.
