A Review on Microspheres: Preparation, Characterisation, Evaluation and Applications

Abstract

Now a day the recent development in new drug delivery systems plays a vital role in pharmaceutical industries. The drug delivery practice has been modified in the last decades and even many advanced innovations happened in recent times. Newer drug delivery systems are largely influencing the current medical practice. The idea of targeted drug delivery is to concentrate the treatment in the target tissues while lowering the relative concentration of the drug in the non-target tissues. As a result, the medication is concentrated at the desired location. As a result, the medication has no effect on the tissues nearby. Therefore, by combining the drug with a carrier particle like microspheres, nanoparticles, liposomes, niosomes, etc. that regulates the release and absorption characteristics of the drug, carrier technology offers an intelligent way for drug delivery. Microspheres attracted a lot of interest for their sustained release as well as their ability to direct anti-cancer medications to the tumour. Microspheres will play a key role in novel drug delivery in the future by fusing together a variety of other strategies, especially in diseased cell sorting, diagnostics, gene & genetic materials, safe, targeted, and efficient in vivo delivery, and supplements as miniature representations of diseased organs and tissues in the body.
