<p>A drug carrier formulation consisting of magnetically-localizable, biodegradable lipid microspheres containing a magnetically-responsive substance, one or more diodegradable lipids and one or more nontoxic surfactants is described herein. There is also described a process for preparing such microspheres wherein the magnetically-responsive substance is wetted with surfactant and part of the lipids, then this material is added to the remaining lipids and heated to 90-100 DEG C., water is added, the mixture is sonicated to obtain a microemulsion, which is then cooled and lyophilized to obtain the product.</p> |
