Abstract:
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 by using numerous unit dosage forms such as microgranules/spheroids, pellets, microcapsules, and beads, which are divided into many separate units, referred to as subunits, each of which possesses certain 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. The traditional procedures require the use of ionotropic gelation methods, which include internal and external gelation methods, emulsion gelation methods, polyelectrolyte complexation methods, and so on. 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.
