Ganciclovir for Injection, USP contains ganciclovir, in the form of the sodium salt for intravenous injection. Ganciclovir is a synthetic guanine derivative active against cytomegalovirus (CMV). Chemically, ganciclovir is 9-[[2-hydroxy-1-(hydroxymethyl)-ethoxy]methyl]guanine and ganciclovir sodium is 9-[[2-hydroxy-1-(hydroxymethyl)-ethoxy]methyl]guanine, monosodium salt. The chemical structures of ganciclovir sodium and ganciclovir are: Ganciclovir is a white to off-white crystalline powder. Ganciclovir is a polar hydrophilic compound with a solubility of 2.6 mg/mL in water at 25°C and an n-octanol/water partition coefficient of 0.022. The pK a s for ganciclovir are 2.2 and 9.4. Ganciclovir for Injection, USP, formulated as monosodium salt, using sodium hydroxide as a salt forming agent, is a sterile white to off-white lyophilized powder. The lyophilized powder has an aqueous solubility of greater than 50 mg/mL at 25°C. At physiological pH, ganciclovir sodium exists as the unionized form with a solubility of approximately 6 mg/mL at 37°C. Each vial contains 543 mg ganciclovir sodium equivalent to 500 mg ganciclovir. Inactive ingredients may include hydrochloric acid (QS) and sodium hydroxide (QS) added to adjust the pH. All doses in this package insert are specified in terms of ganciclovir.
