Compositions of tannate salts of phenylephrine, pyrilamine, and dextromethorphan produced by a method that allows for the in-situ conversions and incorporation of the tannate salts in a single dosage form. The conversion process includes dissolving salts of phenylephrine, pyrilamine, and dextromethorphan in a solvent and mixing with a dispersing agent and tannic acid to generate tannate salts. The tannate salts may be further processed without further purification or isolation to single dosage forms, such as tablets and suspension.
