Nortilidine
Nortilidine is an opioid analgesic and the primary active metabolite of tilidine. It is known for its potent analgesic properties and is used in the management of moderate to severe pain.
Pharmacology[edit]
Nortilidine acts primarily as an agonist at the mu-opioid receptor, which is responsible for its analgesic effects. It also has some activity at the delta-opioid receptor and kappa-opioid receptor, although these effects are less pronounced. The compound is known to inhibit the reuptake of serotonin and norepinephrine, contributing to its analgesic and mood-enhancing properties.
Metabolism[edit]
Nortilidine is formed in the liver through the N-demethylation of tilidine, a process primarily mediated by the cytochrome P450 enzyme system, particularly CYP3A4 and CYP2C19. The conversion of tilidine to nortilidine is essential for its analgesic activity, as tilidine itself has minimal pharmacological effects.
Clinical Use[edit]
Nortilidine is used in the treatment of various types of pain, including neuropathic pain, postoperative pain, and cancer pain. It is often administered in combination with other analgesics to enhance pain relief.
Side Effects[edit]
Common side effects of nortilidine include nausea, vomiting, constipation, drowsiness, and dizziness. Like other opioids, it has the potential for abuse and dependence. Long-term use can lead to tolerance and withdrawal symptoms upon discontinuation.
Legal Status[edit]
The legal status of nortilidine varies by country. In some regions, it is classified as a controlled substance due to its potential for abuse and dependence.
