Mivacurium induces LAD2 cell degranulation in a dose-dependent manner. Mivacurium stimulates intracellular Ca ²⁺ influx in MRGPRX2-HEK293 cells but not in NC-HEK293 cells. Mivacurium induces the release of only low levels of mediators in LAD2 cells transfected with MRGPRX2-targeted small interfering siRNA.

Mivacurium causes pseudo-allergic reactions in C57 wild-type mice by inducing mast cells to release histamine and a decrease in body temperature.
Mivacurium is rapidly hydrolyzed in the plasma and has a short duration of action (< 10 min). Mivacurium has many advantages, such as a rapid effect, nonneurological toxicity and a lack of heart rate alteration.
