Penicillin G Potassium structural formula illustration

Penicillin G Potassium Injection, USP (equivalent to 1, 2, or 3 million units of penicillin G) is a 50 mL premixed, iso-osmotic, sterile, nonpyrogenic, frozen solution for intravenous administration. Dextrose, USP has been added to the above dosages to adjust osmolality (approximately 2 g, 1.2 g, and 350 mg as dextrose hydrous, respectively). Sodium Citrate, USP has been added as a buffer. The pH has been adjusted with hydrochloric acid and may have been adjusted with sodium hydroxide. The pH is 6.5 (5.5 to 8.0). The solution is contained in a single dose GALAXY container (PL 2040 Plastic) and is intended for intravenous use after thawing to room temperature.

This GALAXY container is fabricated from a specially designed multilayer plastic (PL 2040). Solutions are in contact with the polyethylene layer of this container and can leach out certain chemical components of the plastic in very small amounts within the expiration period. The suitability of the plastic has been confirmed in tests in animals according to the USP biological tests for plastic containers as well as by tissue culture toxicity studies.
