Abstract

This review discussed the usage of microbeads as a medication delivery mechanism and natural polymers. Any drug delivery system's purpose is to deliver a therapeutic amount of medicine to the appropriate place in the body while also achieving and maintaining the correct drug concentration. This could be accomplished using a multiparticulate dosage form, such as beads, which are divided into numerous separate pieces, known as subunits, each of which possesses some desired features. The advantages of micro particle drug delivery systems over single unit dose form are well documented. One of the solutions that does not entail the use of harsh chemicals or elevated temperatures is the production of microbeads medication delivery systems. Conventional procedures include the use of ionotropic gelation, emulsion gelation, polyelectrolyte complexation, and other methods. Because of the ease of preparation, the majority of work has been done on the preparation of microbeads using the ionotropic gelation process rather than alternative approaches. The ionotropic gelation approach relies on the capacity of polyelectrolytes to crosslink with counter ions to generate a hydrogel sustained release formulation.
