Figure 1: The Chemical Structure of Levofloxacin, USP The molecular formula is C 18 H 20 FN 3 O 4 • 1⁄2 H 2 O and the molecular weight is 370.38. Levofloxacin, USP is a light yellowish-white to yellow-white crystals or crystalline powder. The molecule exists as a zwitterion at the pH conditions in the small intestine. The data demonstrate that from pH 0.6 to 5.8, the solubility of levofloxacin, USP is essentially constant (approximately 100 mg/mL). Levofloxacin, USP is considered soluble to freely soluble in this pH range, as defined by USP nomenclature. Above pH 5.8, the solubility increases rapidly to its maximum at pH 6.7 (272 mg/mL) and is considered freely soluble in this range.
