Abstract
The stability of methicillin, amikacin, erythromycin lactobionate, vancomycin, and ticarcillin in plastic intravenous containers of sodium chloride injection 0.9%, USP and dextrose 5% injection, USP was studied. The study was conducted under aseptic conditions for a period of 24 hours. The samples, drawn at various times, were assayed by a modified agar gel diffusion technique. The study solutions were stored at room temperature. This study revealed that amikacin, methicillin, vancomycin, and ticarcillin are stable for 24 hours in the test solutions. Erythromycin lactobionate is stable for 24 hours in normal saline, but the addition of sodium bicarbonate 4% (Neut®) was necessary to assure stability in dextrose 5 %.
