Abstract

Advances in drug delivery systems have revolutionized the field of healthcare by enhancing therapeutic efficacy and improving patient compliance. Traditional drug delivery methods often faced challenges such as poor bioavailability, low solubility, rapid clearance from the body, and inconsistent drug release profiles. However, recent innovations in drug delivery have overcome these limitations, leading to more efficient and targeted treatments. One major advancement in drug delivery is the development of nanotechnology-based systems. Nanoparticles, liposomes, and micelles are engineered to encapsulate drugs, protecting them from degradation and enabling precise delivery to the desired site of action. These nanocarriers can be designed to release the drug in a controlled manner, prolonging its therapeutic effect and reducing the frequency of administration. Furthermore, their small size allows for enhanced cellular uptake, increasing drug concentration at the target site while minimizing side effects on healthy tissues.
