`ABSTRACT
`(57)
`The subject matter described herein is directed to stable
`L-cysteine compositions for injection, comprising: L-cyste(cid:173)
`ine or a pharmaceutically acceptable salt thereof and/or
`hydrate thereof in an amount from about 10 mg/mL to about
`100 mg/mL; Aluminum in an amount from about 1.0 parts
`per billion (ppb) to about 250 ppb; cystine in an amount
`from about 0.01 wt% to about 2 wt% relative to L-cysteine;
`pyruvic acid in an amount from about 0.01 wt % to about 2
`wt % relative to L-cysteine; a pharmaceutically acceptable
`carrier, comprising water; headspace 0 2 that is less than
`1.0%; dissolved oxygen present in the carrier in an amount
`from about 0.01 parts per million (ppm) to about 1 ppm,
`wherein the composition is enclosed in a single-use con(cid:173)
`tainer having a volume of from 10 mL to 100 mL. Also
`described are compositions for a total parenteral nutrition
`regimen and methods for their use.
