Advances in drug delivery systems are continually being made to overcome these challenges. Some cutting-edge technologies include:
Nanoparticles: Engineered to deliver drugs at the cellular level, nanoparticles can improve drug stability, enhance permeability, and target specific tissues more effectively. Hydrogels: Used for controlled drug release, hydrogels can be designed to respond to specific histological triggers, such as pH or temperature changes. Liposomes: Composed of lipid bilayers, liposomes can encapsulate drugs and deliver them directly to target cells, minimizing side effects. Biodegradable Polymers: These materials can be designed to degrade at a controlled rate, providing sustained drug release over time. Microneedles: For transdermal delivery, microneedles can painlessly penetrate the skin to deliver drugs directly to the underlying tissues.
