Compositions and methods for treating disordered tissues, such as caused by pathogens and/or by toxins. The treatment compositions include an anti-infective active agent, a liquid carrier, and benzocaine in an amount so that the treatment composition penetrates more quickly into disordered tissue compared to the treatment composition in the absence of the benzocaine. In addition, the benzocaine can increase residence time of the anti-infective active in the treatment area. The preferred anti-infective active agent can be an organohalide, such as a quaternary ammonium halide compound, an example of which is benzalkonium chloride. The treatment compositions and methods may employ the use of an applicator adapted for use in promoting penetration of the treatment composition and/or agitation of the disordered tissue to further enhance penetration.
