  • Patent number: 6548478
    Abstract: A mixture comprising: a) virginiamycin; b) a pharmaceutically acceptable and substantially anhydrous wetting agent including sodium lauryl sulfate; c) a sufficient amount of pharmaceutically acceptable buffering agent to provide a pH of from about 3 0 to about 7.0 when said mixture is added to water; and d) from about 0.5 weight percent to about 10 0 weight percent colloidal silicon dioxide, wherein the ratio of the weight percent of (b) to the weight percent of (a) percent by weight is at least about 1.5:1. The mixture is designed to be added to water to produce a stable suspension of the virginiamycin, which can then be applied to, for example, feed grain.
