Protease inhibition increases the analgesic potency of peptide E.
Peptide E (PE), an opioid peptide from adrenal medulla, is known to possess very low analgesic potency when injected intracerebroventricularly in mice. The present study showed that PE analgesia was increased by co-injection with protease inhibitors (bacitracin and bestatin).
