Microspheres - Novel Drug Carriers

Abstract

Conventional drug delivery systems have a major disadvantage of frequent dosing to maintain the levels of the drug in the therapeutic region required to treat the disease. Controlled drug delivery systems were introduced to overcome the frequent administrations and increase patient compliance reducing the cost of treatment. Controlled release systems also helped in achieving the desired feature of delivering the drug at a predetermined rate and at the desired target. Many of these drawbacks can be overcome by the new drug carriers – Microspheres. Microspheres based drug delivery has gained great importance in recent time. The important feature of controlled release of microspheres comes from its nature of phase separation is the micro phase separation morphology which provides it with the characteristic of controlled rate of degradation and drug release.
