Neomycin Sulfate 25 mg/mL Oral Solution

摘要

Calculate the required quantity of each ingredient for the total amount to be prepared. Accurately weigh or measure each ingredient. Heat about 75 mL of purified water to about 75°C; add the methylparaben, propyl-paraben, and methylcellulose 1,500, and mix until dissolved. Cool the solution to room temperature and add the neomycin sulfate, benzoic acid, glycerin, sodium cyclamate, sodium phosphate, and cherry flavor; mix until dissolved. Adjust the pH to the range of 5.0 to 7.5 using sul-furic acid 10% solution, if necessary.
