Review on Microspheres

Abstract

Microspheres can be employed to deliver medication in a rate-controlled and sometimes targeted manner. Medication is released from a microsphere by drug leaching from the polymer or by degradation of the polymer matrix. The current review provides an in-depth discussion of therapeutic aspects of microsphere drug delivery including consideration of the prerequisite area for micro particulate, types of polymers used, method of preparation, method of release & kinetics, type of microspheres in brief, characterization & targeting of microspheres & practical aspects of microspheres
