Abstract

The present invention provides viscoelastic gel compositions comprising microparticles which are capable of interacting with each other in a non-ionic manner, thus forming a gel network. The gel compositions may incorporate active agents and provide controlled release of such agents. The compositions are useful as injectable depot formulations of therapeutic compounds. In a further aspect, microparticles capable of gel formation in an aqueous environment are provided, as well as method of making viscoelastic gels based on the interaction of uncharged microparticles. Moreover, the invention discloses kits for making viscoelastic gel compositions and uses thereof.
