Abstract
The invention pertains to a novel composition comprising guaifenesin tannate and to a method for preparing guaifenesin tannate by reacting guaifenesin with tannic acid at a temperature above the melting point of guaifenesin. The guaifenesin tannate has extended release properties and is useful in pharmaceutical compositions as an expectorant in warm-blooded animals or as a muscle relaxant in non-human animals.
