A Brief Insight into Nanotherapeutic Approaches in the Management of Analgesia

Background: Growing public awareness of chronic pain resulting from illness and injury has prompted pharmaceutical researchers and drug corporations to create better, more targeted painkillers. For effective pain management, prolonged analgesic medication delivery at the intended areas continues to be a major problem such as addiction, tolerance and other serious side effects, which can prolong suffering and decrease painkiller effectiveness. Objective: The present paper focuses on review of current advances in the field of pain treatment by different nanoparticles formulations of various drugs, by enhancing their pharmacokinetic factors and diminishing associated adverse effects. Results: According to literature survey, usage of nano-carriers enables the delivery of these drugs to target locations with less systemic toxicity. Nanotechnology for varied therapeutic purposes, different analgesics have been loaded onto different nano carriers, including those that are natural, synthetic, and polymeric and proven to be beneficial in pain management. Conclusion: Overall, new nano based preparations and new ways to utilize existing medications in a variety of circumstances is a multimodal approach to pain relief, have resulted in recent advancements in the pharmacological management of pain.
