An Explicative Review on Nanotechnology-based Drug Delivery Systems for Alleviating Oxidative Stress-driven...

Numerous chronic illnesses, including diabetes, cancer, cardiovascular disease, and neurological disorders, are mostly caused by oxidative stress, which is defined as an imbalance between the body's antioxidant defenses and the generation of reactive oxygen species (ROS). The success of traditional treatments for oxidative stress has been limited because antioxidant medications are not well-absorbed, are quickly broken down, and do not target specific areas of the body.

Drug delivery methods based on nanotechnology offer a viable solution to these issues by providing therapeutic molecules with improved release characteristics, enhanced bioavailability, and targeted capabilities. Recent developments in nanotechnology have enabled the creation of multipurpose carriers that can simultaneously transmit genes for endogenous antioxidant enzymes and antioxidants.

This integration promotes a long-term healing response and addresses the immediate oxidative stress. Likewise, functionalizing nanocarriers with particular ligands improves localization to oxidative stress locations, including inflammatory tissues or tumor microenvironments, boosting therapeutic efficacy. The potential of nanotherapeutics in reducing oxidative stress-driven diseases is examined in this article.

Nanotechnology-based drug delivery approaches offer a novel avenue for the treatment of several oxidative stress-induced diseases. These delivery systems are highly target-specific and have a longer duration of action. Still, more research is needed to address issues, such as safety margins, largescale production, and approval of medicine use.

We address several nanocarrier platforms, such as liposomes, polymeric nanoparticles, dendrimers, and metallic nanoparticles that have proven more effective in delivering therapeutic drugs and antioxidants to specific sites of oxidative damage. Furthermore, nanotherapeutics may enhance their therapeutic potential by protecting these bioactive substances from premature degradation and clearance.
