Answer
: a
Recently approved by the FDA, Ryanodex (Eagle Pharmaceuticals) is an
injectable suspension of dantrolene sodium that will be available in 250-mg sin-
gle-use vials containing the active ingredient in a lyophilized powder. Eagle says
a full loading dose of Ryanodex can be prepared and administered in less than 1
minute, compared with 15 to 20 minutes for conventional dantrolene. But, for
that convenience, you'll pay. The drug costs more than twice as much as the
other brands, Dantrium (Par Pharmaceutical) and Revonto (US WorldMeds),
and has a shorter shelf life of 2 years, versus 3 years for the others.

Most cases of MH occur during general anesthesia, however, the 1-hour period
immediately following surgery is also a critical time. While rare, it can happen in

addition, MH can occur if triggering anesthetics, including succinylcholine, are
used outside of the operating room in areas such as emergency rooms, dental
clinics, surgeons' offices or intensive care units.
