This review article, "Microspheres As
Innovative Carriers for Controlled and Targeted Drug Delivery," provides a comprehensive overview of microsphere technology in pharmaceutical science. Microspheres, which are small spherical particles, are highlighted as an innovative and versatile platform for achieving controlled and sustained drug administration and targeted delivery. The paper covers the key aspects of these delivery systems, including the materials (such as biodegradable and synthetic polymers) and preparation techniques (like single emulsion, double emulsion, and spray drying), along with their characterization and wide-ranging applications in areas like vaccination, tumour treatment, and oral, topical, and ocular delivery. By encapsulating various drugs, microspheres offer significant benefits such as reducing adverse effects, improving patient compliance, and boosting
