Abstract

A sterile storage stable ready-to-inject epinephrine composition contained within a flexible container and packaged within a secondary container, the composition including an aqueous pharmaceutically acceptable carrier containing epinephrine and a metal ion chelator, the epinephrine being present in a concentration of equal to or less than 0.07 mg/mL, substantially all of the epinephrine being an R-isomer, the composition having a pH of between 3.5-4.7, and the composition having, after storage of at least one month at 25° C., total impurities of equal or less than 0.7% and equal or less than 4% S-isomer content.

Claims (25)

1 . A sterile storage stable ready-to-inject epinephrine composition contained within a flexible container and packaged within a secondary container,

wherein the composition comprises an aqueous pharmaceutically acceptable carrier containing epinephrine and a metal ion chelator,

wherein the epinephrine is present in a concentration of equal to or less than 0.07 mg/mL,

wherein substantially all of the epinephrine is an R-isomer,

wherein the composition has a pH of between 3.5-4.7,

wherein the composition has, after storage of one month at 25° C., equal to or less than 4% S-isomer content, and

wherein at least one of the flexible container and the secondary container has an oxygen transmission rate between 0.0005 to 0.005 cc/100 in 2 /24 hrs.

2 . The composition of claim 1 , wherein the secondary container comprises an aluminum foil overwrap.

3 . The composition of claim 2 , wherein the aluminum foil overwrap comprises an oxygen scavenger.
