<unk>  or N-methyltetrahydropapaverine is a recognized metabolite of atracurium and cisatracurium.<unk>  decreases the seizure threshold, and thus it can induce seizures if present at sufficient threshold concentrations; however such concentrations are unlikely to be produced consequent to chemodegradable metabolism of clinically administered doses of cisatracurium or atracurium. Capsule of Papaver somniferum showing latex (opium) exuding from incision.<unk>  occurs naturally in small amounts (0.1%) in opium.<unk>  also occurs naturally in minute amounts (0.1%) in opium, from which it was first isolated in 1871. Partial dehydrogenation of<unk>  will lead to papaverine, the alkaloid found in the opium poppy plant (Papaver somniferum).<unk>  is a benzyltetrahydroisoquinoline alkaloid. It has been shown to interact with GABA receptors, glycine receptors, opioid receptors, and nicotinic acetylcholine receptors, but not benzodiazepine or muscarinic receptors, which are also involved in epilepsy and other types of seizures.
