Abstract

A stabilized febantel formulation comprising febantel, a water-miscible organic diluent and an acid, base or buffer salt in an amount such that when diluted 1:10 with water the formulation has a pH value of about 3 to 5. The formulation is far more stable than in the absence of the acid, base or buffer salt.
