ABSTRACT:
A composition, for producing pain relief in a body region, comprises a sterile, stable suspension of butyl aminobenzoate in a non-toxic, aqueous carrying medium in which the butyl aminobenzoate is substantially insoluble. The aqueous carrying medium consists essentially of water as the major constituent and a suspending agent composed of (a) polyethylene glycol and (b) a wetting agent for the butyl aminobenzoate, with a ratio of (a) to (b) in the range of about 50/1 to 125/1. The butyl aminobenzoate is milled to a particle size in the range of about 5 to 50 microns in the presence of the suspending agent.
