  • Patent number: 4775667
    Abstract: Topical analgesic anti-inflammatory compositions containing a corticosteroid in addition to the conventional efficacy-proven ingredients are disclosed. They may be embodied in an aerosol, a solution and any other type of composition being convenient for administration. More than the sum of effects of the individual ingredients has been proved. In other words, the effects of the salicylate esters and L-menthol are synergistically enhanced by the addition of the corticosteroid. Particularly, the persistency of the analgesic/anti-inflammatory effects of the conventional ingredients has been proved to be dependent upon the the concentration of the corticosteroid in the composition.
