US12295932 — Succinylcholine chloride prefilled syringe

USPTO Abstract

Prefilled syringes containing a succinylcholine chloride composition, where the prefilled syringes comprise a syringe barrel and a syringe tip comprising cyclic olefin monopolymer (“COP”) or cyclic olefin copolymer (“COC”). The syringes can also comprise a luer adapter integral with the syringe tip, where the syringe barrel, syringe tip and luer adapter are a single element comprising COP or COC. The succinylcholine chloride compositions include succinylcholine chloride, a tonicity agent and one or more pH adjusters in an aqueous solution having a pH from about 3.0-4.5. The prefilled syringes containing the succinylcholine compositions are storage-stable for extended periods of time at a temperature of 2-8° C., have acceptable physical parameters such as glide force and break force, and make safe and robust connections with needles and needleless luer adapter devices (“NLADs”).
