Treatment Summary
Dantrolene is a medicine that does not work the same way as other drugs in its class, such as phenytoin. It is made from a chemical called a hydantoin derivative.

How Ryanodex Affects Patients
Dantrolene is a medicine that helps relax the muscles. It is the only treatment for a dangerous condition called malignant hyperthermia. It works by interfering with the release of calcium from the muscles, which helps restore normal levels of calcium in the cells. In malignant hyperthermia, it is believed that certain drugs (like general anesthetics and muscle relaxants) cause an increase in calcium levels in the muscle cells, which can lead to a dangerous situation. Dantrolene helps bring the calcium levels back to normal.
How Ryanodex works in the body
Dantrolene works on muscle cells to prevent them from contracting. It does this by binding to a receptor in the muscle, which stops calcium from being released. Calcium is needed for muscles to contract, so without it, the muscle cannot move.
When to interrupt dosage
The optimal dose of Ryanodex is contingent upon the diagnosed condition, including Stroke, Spasticity and Spinal Cord Injury. The amount of dosage is reliant on the mode of delivery (e.g. Capsule - Oral or Injection, Solution - Intravenous) featured in the table underneath.
