Microspheres-Novel Drug Delivery Carrier for Plant Extracts for Antibacterial Activity

Last several years, great advances had taken part in development of novel drug delivery system in plant extracts and active moieties. The various disadvantages associated with the conventional therapy can be surmount by means of well- controlled novel drug delivery system and also enhances patient compliance. Such systems deliver optimum amount of drug at correct time, cause less toxicity and minimal side effects. Microspheres are very small spherical particles, which is having diameter in the micrometer range mostly 1µm -1000µm. In microspheres, drugs are dispersed as crystalline or finely divided form. The herbal formulations are also incorporated to microspheres. This review highlights the importance of microspheres as a drug delivery carrier for plant extracts for antibacterial activity
