About 582 mg (3.34 mole) of particulate arginine was dissolved in 50 ml of distilled water. Additionally, about 1.0 grams (1.67 mole) of ceftriaxone was dissolved in 50 ml of a separate volume of distilled water. The solution containing arginine was adjusted with 1N-HCl until the pH reached 6.0. The ceftriaxone solution was then added to the arginine solution and stirred by a magnetic stirrer at room temperature for 1 hour forming a ceftriaxone-arginine solution. To the ceftriaxone-arginine solution was added about 400 mg of carrageenan and the solution was stirred by magnetic stirrer at room temperature for 2 hours. A ceftriaxone-arginine-carrageenan complex was formed which was freeze-dried while in the swollen state, yielding about 1.84 g of the freeze dried complex.
