Lappaconitine is an alkaloid isolated from the root of Aconltitum sinomantanum Nakai. It has a strong analgesic activity that does not involve the opioid receptor. It was shown to have class-I antiarrhythmic action and irreversibly blocks cloned human heart (hH1) channels by binding to the site 2 receptor.

Sample Use Guides

In Vivo Use Guide

Lappaconitine (8 mg) was intravenously dripped to patients in the lappaconitine group 30 min before ending the operation. PCIA started as soon as the end of the surgery and the total dose of lappaconitine was 36 mg.

Route of Administration: Intravenous

In Vitro Use Guide

Right isolated guinea-pig atria became bradycardic at 3 uM lappaconitine, and at 4.5 uM one of six right atria ceased contracting. Asystolia was also observed in left atria at concentrations about 600 nM, but all of the asystolic atria resumed contraction as the stimulation current was increased, indicating an elevation of the excitation threshold.
