| Description | (+)-Sparteine is a quinoline alkaloid extracted from Scotch broom, a sodium channel blocker and a class 1a antiarrhythmic agent. It competitively inhibits the activity of nicotinic acetylcholine receptors in nerve cells and is a ganglionic blocking agent.  | 
| In vitro | (+)-Sparteine (Pachycarpine) (2 μM) reduces ACh-induced currents caused by activation of nicotinic ACh receptors (AChRs) in a voltage-independent manner at membrane potentials between -50 mV and +30 mV; the ACh dose-response relationship is altered by 2 μM (+)-Sparteine (Pachycarpine) at -50 mV and -90 mV in a manner typical of a competitive but not competitive antagonist.
