Summary for Patent: 10,322,239

Title:	Medicament delivery device for administration of opioid antagonists including formulations for naloxone
Abstract:	Medicament delivery devices for administration of opioid antagonists are described herein. In some embodiments, an apparatus includes a housing, a medicament container disposed within the housing and an energy storage member disposed within the housing. The medicament container is filled with a naloxone composition that includes naloxone or salts thereof, a tonicity-adjusting agent, and a pH-adjusting agent, whereby the osmolality of the naloxone composition ranges from about 250-350 mOsm and the pH ranges from about 3-5. The energy storage member is configured to produce a force to deliver the naloxone composition.
