Testing early argipressin for shock not helped by norepinephrine
This trial tests a medicine called argipressin for people in the ICU with vasoplegic shock (very low blood pressure due to widened blood vessels) that isn't improving with high doses of the usual medicine, norepinephrine. The goal is to see if adding argipressin early helps raise blood pressure and improves outcomes.
DijonAges 18 years+ - NCT07338279Recruiting

- How do I know if I qualify for a data collection trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a data collection trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
