Researchers from the University of Seville have patented a pain relief approach that uses nanotechnology to deliver a cannabinoids-based formula to relieve chronic neuropathic pain.
Investigators say a scheduled release of the derived cannabinoid provided neuropathic pain relief in rats for a period of eleven days after the oral administration of a single dose.
The research appears in Nanomedicine: Nanotechnology, Biology, and Medicine.
The innovative approach is based on using polymer nanoparticles to deliver active ingredients developed by the researchers for the treatment of chronic pain.
Nanotechnology is used to encapsulate the main active ingredients in a polymer matrix composite. In this way, it is possible to extend the therapeutic effect while reducing the dose of medicine it is necessary to administer.
In addition, the active ingredients cannot cross the blood-brain barrier, which removes any potential psychoactive effect.
Researchers believe the new technology will be a very important advance in the treatment of chronic pain.
According to one of the company’s managers, “Their system has proven to be more effective than other methods, such as inhalation or ingestion, for administering these composites”.
