ABSTRACT:
This invention relates to a topical spray preparation for burn treatment and microbial infections on human being or animals. This non-aerosol preparation contains an antimicrobial drug, i.e., silver sulfadiazine, as is dispersed or solubilized in a cream or lotion base matrix which can be sprayed directly from a common trigger spray device. The key component of the matrix can be characterized by it having a suitable molecular weight polymer of cross-linked acrylic acid, such as Carbomers or non-ionic surfactants such as polyoxyethylene alkyl ethers, or any combination of the above materials.
