Abstract:
The authors provide a report on the preparation of an extemporaneous liquid formulation of diazepam enema using an alcohol-free base solution for use by both pediatric and adult patients. A solubility study using this base and the chemical stability of the drug in this formulation was performed by using a high-pressure liquid chromatography analytical method. Results of this study showed that the intrinsic solubility of the drug in this liquid base was 6.03 mg/mL ± 0.06 mg/mL and that diazepam was chemically stable when the formulation was stored at 25°C over a period of 3 months.
