Reaktionsschritte
To a 5 L stainless steel vessel were added 0.68 g citric acid USP, 1.99 g sodium citrate USP, and 17.5 g sodium chloride USP. Purified water USP (2 L) was added to the stainless steel vessel and the contents were mixed with an overhead stirrer at a speed of 240 rpm for 10 minutes. Formoterol fumarate dihydrate (0.17 g for low dosage strength formulation, 0.34 g for high dosage strength formulation) was added and the solution was stirred at 240 rpm for 90 minutes.
