HCID 3516Guaifenesin

Procedure

The maltitol was similarly admixed with Phase F to form Phase G to which the ammonium glycyrrhizinate was added with another about 5 minutes mixing time being used. The flavors and colorants were then admixed, with a mixing time of about 5 minutes, followed by addition of a sufficient amount of liquid fructose to make the desired volume and mixing to homogeneity. The pH value was thereafter adjusted to be between 4 and 5 using a citric acid or sodium citrate solution. This composition provides 100 mg of guaifenesin per 5 mL (teaspoon).
