Mechanism of Action
Lappaconitine acts primarily as a voltage-gated sodium channel blocker, inhibiting neuronal signal transmission. It also exhibits anti-arrhythmic activity by blocking cardiac sodium channels and demonstrates additional anti-inflammatory and antitumor effects in vitro and in vivo plantgrowthhormones.com+15drugs.ncats.io+15pmc.ncbi.nlm.nih.gov+15.
Research Applications & Pharmacology
Analgesia models: Effective in treating cancer pain, neuralgia, and postoperative pain without opioids.
