A well-designed controlled drug delivery system can address the drawbacks of traditional medication therapy while also improving a medicine's therapeutic efficacy. Because of their spherical shape, microspheres are often referred to as regulated drug delivery systems with particle sizes smaller than 200 micrometre following ball bearing effects. The therapeutic efficacy of drug-filled microspheres is determined by their properties, which can be adjusted by changing the materials, procedures, polymers, or techniques utilised. Microspheres as a novel medication delivery mechanism are the subject of this review. To achieve the required or enhanced therapeutic efficacy of a certain medicine, it is vital to deliver that particular agent to the target tissues in optimal amount at the correct time, with an emphasis on preparation, application, biocompatibility, and stability. The control drug delivery system is concerned with the systemic release of a pharmacological agent in order to keep a therapeutic amount of drug in the body for a long time. This can be accomplished by integrating the therapeutic ingredient into biodegradable polymers and continuously releasing the substance as the matrix erodes.
