Why the study?
The time actually needed to prepare dantrolene nanosuspension for a 70 kg dose had not been documented.
Does dantrolene nanosuspension reduce preparation time compared to dantrolene sodium?
Does dantrolene nanosuspension reduce preparation time compared to dantrolene sodium?
Mean Difference: 135.1
Absolute Event Rate: 53.9% vs 189%
p-value: p=<.01
Dantrolene nanosuspension significantly reduces the time required for reconstitution and administration compared to traditional dantrolene sodium, which is critical during a malignant hyperthermia crisis.

May expedite malignant hyperthermia treatment; extends Level 1 evidence supporting nanosuspension adoption in emergencies.
McAvoy et al. (2019) conducted a letter in Malignant hyperthermia (n=20). Dantrolene nanosuspension (Ryanodex) vs. Dantrolene sodium (Dantrium) was evaluated on Time to reconstitute and administer a single vial (MD 135.1 seconds, p=<.01). Dantrolene nanosuspension significantly reduced the mean time to reconstitute and administer a single vial compared to dantrolene sodium (53.9 vs 189 seconds; P<0.01).
