Targeted drug delivery is a medical approach that aims to deliver medication directly to a specific area of the body, such as a tumor or inflamed tissue. This method enhances the effectiveness of the treatment while minimizing side effects, as it reduces the exposure of healthy tissues to the drug. Techniques often involve using carriers like nanoparticles or liposomes that can transport the drug precisely where it is needed. This strategy is particularly beneficial in treating diseases like cancer, where traditional therapies can harm surrounding healthy cells. By focusing on the affected area, targeted drug delivery can improve patient outcomes and reduce the overall dosage required, making treatments safer and more efficient.
