Analgesic
Analgesic — A compound that reduces pain perception. Endorphins and enkephalins are endogenous peptides with analgesic properties studied in pain research.
What Is an Analgesic?
An analgesic is a substance that reduces pain without causing loss of consciousness. Endogenous opioid peptides (beta-endorphin, enkephalins, dynorphins) are the body's natural analgesic system, activating mu, delta, and kappa opioid receptors. Synthetic peptide analgesics aim to produce pain relief with fewer side effects than traditional opioids.
Peptide Analgesic Approaches
- Biased opioid peptides: G-protein-biased mu-agonists for analgesia without respiratory depression
- Conotoxins: Ziconotide (cone snail peptide) blocks N-type calcium channels for severe chronic pain
- Substance P antagonists: NK1 receptor antagonists for neurogenic pain and inflammation
- CGRP antibodies: Anti-CGRP monoclonal antibodies for migraine prevention
