1. An apparatus, comprising:
- a housing;
a medicament container disposed within the housing, the medicament container containing a naloxone composition;
an elastomeric member movably disposed within the medicament container, the elastomeric member formulated to be compatible with the naloxone composition, at least a portion of the elastomeric member including a silicone-based material; and
an energy storage member disposed within the housing, the energy storage member configured to produce a force that is exerted on the elastomeric member to deliver the naloxone composition,wherein the naloxone composition includes naloxone or salts thereof, a tonicity-adjusting agent, and a pH adjusting agent, whereby at least one of (A) the osmolality of the naloxone composition ranges from about 250-350 mOsm or (B) the pH ranges from about 3-5.

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.

22. An apparatus, comprising:
-
a medicament container containing a naloxone composition, the naloxone composition including naloxone or salts thereof, a tonicity-adjusting agent, and a pH adjusting agent, whereby the pH of the naloxone composition ranges from about 3-5; an elastomeric member configured to be disposed within the medicament container and configured to be in contact with the naloxone composition, the elastomeric member including a silicone-based material; a carrier including a needle, the carrier configured to receive at least a distal end portion of the medicament container such that an end portion of the needle is fluidically isolated from the medicament container when the medicament container is in a first position within the carrier, the end portion of the needle being in fluid communication with the medicament container when the medicament container is in a second position within carrier; and a movable member configured to exert a force on the elastomeric member to move the medicament container from the first position to the second position, and to deliver the naloxone composition via the needle. - View Dependent Claims (23, 24, 25, 26)
