Opioid receptor agonists, with morphine being a representative example, are the most widely used, powerful analgesics in clinical practice. These drugs effectively relieve pain, particularly postoperative pain and pain associated with advanced cancer. However, opioid use can easily lead to tolerance and hyperalgesia, often developing within a week. Once tolerance and hyperalgesia develop, the dose must be continuously increased to maintain the analgesic effect. This means that the body requires larger doses of the drug to achieve the same analgesic effect as the initial dose. Higher doses, however, can lead to more severe hyperalgesia, tolerance, constipation, addiction, and respiratory depression. Cobra neurotoxin peptides can both inhibit the hyperalgesia and tolerance associated with opioids and enhance their efficacy. When used in combination with opioids, they enable the latter to achieve analgesia at lower doses without developing tolerance and hyperalgesia, thus resolving the clinical challenge of long-term opioid use.
