This results in a quick start of action— often within one to 2 minutes when administered intravenously— making it an ideal choice for acute surgeries and emergency interventions.

The Significance of the “Citrate” Form

Induction: Often utilized as part of the rapid sequence induction to blunt the cardiovascular reaction to intubation.
