Abstract | AIMS: MAIN METHODS: ESL's effects in the orofacial formalin test were examined following peroral and local peripheral administration (subcutaneous, into the perinasal region). The involvement of adrenergic/ cholinergic/ opioid receptors was evaluated by intraperitoneally pretreating mice with an appropriate antagonist immediately after peroral application of ESL. We used antagonists of α1‑adrenergic ( prazosin), α2‑adrenergic ( yohimbine), β‑adrenergic (non-selective, propranolol and β1-selective, metoprolol), muscarinic ( atropine), nicotinic ( mecamylamine) and opioid receptors ( naloxone). Additionally, the role of peripheral α2‑adrenergic, β1‑adrenergic, muscarinic and opioid receptors was evaluated by co-injecting ESL with an antagonist into the perinasal area. KEY FINDINGS: SIGNIFICANCE: This study suggests that ESL's efficacy against trigeminal nociception is mediated by peripheral (and possibly central) α2‑adrenergic, muscarinic and opioid receptors, as well as central β1‑adrenergic receptors.
