Abstract

Microspheres are innovative drug delivery systems that address the limitations of conventional drug therapies. They are free-flowing spherical powders, typically made from biodegradable proteins or synthetic polymers, with particle sizes ranging from 1 to 1000 µm. Microspheres offer significant advantages, such as improved drug bioavailability, reduced side effects, increased stability, and the ability to deliver drugs at a controlled rate to specific target sites. This targeted delivery minimizes the impact on non-target tissues, enhancing therapeutic efficacy. Various types of microspheres exist, including bioadhesive, floating, radioactive, and biodegradable microspheres, each designed for specific applications in drug delivery. They are used in multiple fields such as oral drug delivery, gene therapy, cosmetics, and diagnostics. Microspheres are particularly effective for controlled release and targeted drug delivery, providing a reliable method for achieving optimal drug concentration at the target site, reducing toxicity, and improving overall treatment outcomes. The future of microspheres in drug delivery systems is promising, especially in applications like targeted therapies, diagnostics, and genetic material delivery. As research progresses, microspheres will play a more central role in novel drug delivery technologies, offering smart and efficient solutions for treating various diseases. Their ability to release drugs in a controlled manner at the desired location makes them an ideal alternative to conventional single-unit dosage forms, with the potential to revolutionize therapeutic approaches in medicine.
