What is Dantrolene

Chemically, dantrolene is a hydantoin derivative, but does not exhibit antiepileptic activity like other hydantoin derivates such as phenytoin.

Dantrolene mechanism of action

Dantrolene depresses excitation-contraction coupling in skeletal muscle by binding to the ryanodine receptor 1, and decreasing intracellular calcium concentration. Ryanodine receptors mediate the release of calcium from the sarcoplasmic reticulum, an essential step in muscle contraction.
