Mechanism of action
The substance blocks an ion pump called sodium–hydrogen antiporter 1 (NHE-1). While the exact mechanism is unknown, it is speculated that inhibition of this pump reduces sodium and calcium overload in cells of Duchenne patients.
History
Rimeporide was designed as a treatment for chronic heart failure. It was unsuccessful in Phase I clinical trials, but was tolerated well by volunteers. Subsequently, the drug was sold to EspeRare, a Swiss nonprofit organisation that aims at developing drugs for rare diseases. As of May 2015, the substance is in preclinical development for Duchenne.
