Abstract
Lipid matrix carriers are described which provide for the sustained release of bioactive agents in vivo or in vitro. The properties of the lipid matrix carriers of the present invention include high entrapment efficiencies; release of entrapped compounds in their active form; biodegradability and avoidance of vascular occlusion in vivo; and avoidance of sequestration of the bioactive agent in the liver and spleen.
