Abstract: The stability of lisinopril as an extemporaneous syrup compounded from powder was studied. The lisinopril syrup (2 mg/mL) was prepared by incorporating lisinopril powder dissolved in water into simple syrup. Samples of the syrup were stored in amber-colored plastic bottles at 5 and 23°C. At various times during the 30-day study period, the concentration of lisinopril was determined by a stability-indicating high performance liquid chromatography assay procedure. Samples were also visually inspected for color and clarity. Over the 30- day study period, the percentage of the initial concentration remained between 97.46% and 100.54% for the 23°C samples and 98.15% and 100.74% for the 5°C samples.
