Abstract
A composition of polymer-coated particles, and a polymer compound used in forming the particles are disclosed. The polymer compound is composed of a hydrophilic polymer attached to a lipophilic moiety through a linking segment which contains chemical groups through which the compound can be crosslinked to other such compounds. The particles in the composition are prepared by forming lipid structures containing ordered arrays of the polymer compounds, and crosslinking the compounds through their chemical groups. The particles are used for parenteral administration of a pharmaceutical compound which is entrapped in the particles.
