Procedure

The microcrystalline cellulose, mannitol, and sucrose were screened or milled and then blended with levothyroxine sodium for about 6 minutes. Acacia, dissolved in water, and propyl gallate, dissolved in alcohol, were added over about 10 minutes to granulate the mixture. The wet granulation was dried at a temperature below 60° C. until the moisture content was less than about 4%. The dried granulation was sized by passing it through a mill, and then blended with the additional ingredients listed in the table below using conventional mixing equipment.
