Above pH 6.7, the solubility decreases and reaches a minimum value (about 50 mg per mL) at a pH of approximately 6.9. Levofloxacin has the potential to form stable coordination compounds with many metal ions. This in vitro chelation potential has the following formation order: Al +3 >Cu +2 >Zn +2 >Mg +2 >Ca +2 . Figure 1 Excipients and Description of Dosage Forms Levofloxacin Injection The appearance of Levofloxacin Injection may range from a clear yellow to a clear greenish-yellow solution. This does not adversely affect product potency. Levofloxacin Injection Premix in Single-Use Flexible Container is a sterile, preservative-free aqueous solution of levofloxacin with pH ranging from 3.8 to 5.8. This is a dilute, nonpyrogenic, nearly isotonic premixed solution that contains levofloxacin in 5% Dextrose (D 5 W). Solutions of hydrochloric acid and sodium hydroxide may have been added to adjust the pH. The flexible container is fabricated from a specially formulated non-plasticized, thermoplastic copolyolephine. The amount of water that can permeate from the container into the overwrap is insufficient to affect the solution significantly. Solutions in contact with the flexible container can leach out certain of the container's chemical components in very small amounts within the expiration period. The suitability of the container material has been confirmed by tests in animals according to USP biological tests for plastic containers.
