Stability of ganciclovir sodium in 5% dextrose injection and in 0.9% sodium chloride injection over 35 days.

The stability of ganciclovir 1 and 5 mg/mL in 5% dextrose injection and in 0.9% sodium chloride injection was studied at 25 degrees C and 5 degrees C over 35 days. Ganciclovir (as the sodium salt) was added to 120 polyvinyl chloride bags containing either 5% dextrose injection or 0.9% sodium chloride injection to attain ganciclovir concentrations of 1 and 5 mg/mL. Thirty bags were prepared for each combination of drug concentration and i.v. solution. Half of the bags in each group were stored at 25 degrees C; the other half were stored at 5 degrees C. Samples withdrawn from all 120 bags immediately after preparation were frozen for later determination of initial concentration. At 7, 14, 21, 28, and 35 days after preparation, approximately 5-mL samples representing each test condition were withdrawn for analysis. The samples were visually examined, tested for pH, and assayed by high-performance liquid chromatography. There was no significant loss of ganciclovir under any of the study conditions over 35 days. All solutions were clear throughout the study period. The pH decreased slightly in both diluents at both ganciclovir concentrations but did not deviate from the manufacturer's range (9-11). Admixtures containing ganciclovir 1 and 5 mg/mL (as the sodium salt) in 5% dextrose injection and 0.9% sodium chloride injection were stable in polyvinyl chloride bags stored at 25 degrees C and 5 degrees C for 35 days.

Stability and compatibility of ganciclovir sodium in 5% dextrose injection over 35 days.

The stability and compatibility of ganciclovir sodium in 5% dextrose injection over 35 days were assessed. Nine admixtures of ganciclovir sodium 1, 5, and 10 mg/mL in 5% dextrose injection were aseptically prepared. Immediately thereafter, six samples were aseptically withdrawn from each admixture into sterile collection tubes. Three of the samples were frozen for stability-indicating high-performance liquid chromatographic (HPLC) assay at a later date, and the other three were immediately assessed for pH. Each admixture was also assessed visually for color change, turbidity, gas evolution, and precipitation. The admixtures were stored in the dark at 4-8 degrees C and sampled at 10 and 35 days. There was no significant loss of ganciclovir over the 35-day study period. No admixture at any time contained less than 93.4% or more than 103.7% of its initial ganciclovir concentration. There were no appreciable pH changes, and there was no evidence of visual incompatibility. Ganciclovir sodium 1, 5, and 10 mg/mL in 5% dextrose injection was stable for at least 35 days when stored in the dark at 4-8 degrees C.
