Methscopolamine Tannate is prepared from methscopolamine salt and tannic acid salt in aqueous medium. Methscopolamine salt is Methscopolamine bromide or nitrate, preferably methscopolamine bromide, whereas tannic acid salt is an alkali metal salt of tannic acid, preferably potassium salt of tannic acid. The preparation leads to methscopolamine tannate composition having a purity of about 93 wt. %, based on the weight of the composition, with the balance comprising primarily water.
