PARSIPPANY, N.J., Sept. 28 /PRNewswire/ -- JHP Pharmaceuticals, LLC ("JHP") announces that it has developed, and received approval by the FDA for Dantrium@ IV (dantrolene sodium for injection), a rapidly mixing product. Dantrium@ IV now reconstitutes in approximately 20 seconds, which is 4 times faster than before, saving valuable time and effort during a malignant hyperthermia (MH) emergency.

According to the company, the Dantrium@ IV, the rapidly mixing product, offers:

  • Reconstitutes in approximately 20 seconds with noticeably less vigorous shaking required to complete the reconstitution process.
  • Easier and faster introduction of diluent into the Dantrium@ IV vial.

JHP has also introduced two new features in the Dantrium@ IV vial; an easy-to-open flip-off vial cap and an easy-to-identify red vial cap and red vial label.

Stuart Hinchen, co-founder and President of JHP said, "We are excited about the dramatic enhancements we have been able to make to Dantrium@ IV. The stunning improvement in reconstitution time represents breakthrough innovation that significantly heightens the life-saving characteristics of a drug 30 years after its successful introduction. During fulminant MH, when a patient's core temperature can increase by as much 1 degree Centigrade every 5 minutes(1) and time is obviously a crucial factor, Dantrium@ IV can now be reconstituted 4 times faster than before. Taking into account the 36 vials that are recommended by MHAUS (Malignant Hyperthermia Association of the United States) and often needed to stabilize a patient with MH, Dantrium@ IV, the rapidly mixing product, saves up to 36 minutes of mixing time."

Malignant hyperthermia ("MH") is life threatening and manifests in susceptible individuals as a hypermetabolic response on exposure to halogenated volatile anesthetics and depolarizing muscle relaxants(3). Most surgical facilities use MH triggering agents.

Since the introduction of Dantrium@ IV, the mortality and morbidity rate associated with MH has plummeted from a high of 80% to less than 5%(2).
