Which neuromuscular blocking agent does not require refrigeration for storage?

Vecuronium is the neuromuscular blocking agent that does not require refrigeration for storage. When considering the stability and storage conditions of various neuromuscular blockers, vecuronium is stable at room temperature, making it more convenient for use in various medical settings, including tactical and emergency situations.

Rocuronium, on the other hand, is typically stored in refrigeration to maintain its potency and prolong its shelf life. Succinylcholine also requires refrigeration under standard storage guidelines to ensure its effectiveness. Therefore, vecuronium stands out due to its room-temperature stability, allowing for flexibility in storage and easier access when needed, especially in environments where refrigeration might not be feasible.
