20097188 Lee S, Poet TS, Smith JN, Busby-Hjerpe AL, Timchalk C: Effect of in vivo nicotine exposure on chlorpyrifos pharmacokinetics and pharmacodynamics in rats. Chem Biol Interact. 2010 Mar 30;184(3):449-57. Epub 2010 Jan 25.

The objective of this study was to evaluate the impact of repeated nicotine exposure on the pharmacokinetics of chlorpyrifos (CPF) and its major metabolite, 3,5,6-trichloro-2-pyridinol (TCPy) in blood and urine and also to determine the impact on cholinesterase (ChE) activity in plasma and brain.

RATIONALE: Nicotine receptors in the brain are closely related with memory amelioration induced by cholinesterase inhibitors.

These include galantamine, donepezil and rivastigmine (cholinesterase inhibitors), varenicline (partial nicotine agonist), guanfacine (alpha (2)-adrenergic agonist) and atomoxetine (norepinephrine transporter inhibitor).

In rats, ACh moderately elevates nitrite production, whereas ACh, the nicotinic receptor agonists (nicotine, acetyl thiocholine iodide, metacholine) and the cholinesterase inhibitor eserine reduce enteric nitrite formation in snails.

Eur J Pharmacol. 2009 Aug 15;616(1-3):229-35. Epub 2009 Jun 18.


Specifically, Phenthonium increases the spontaneous release of acetylcholine at the motor endplate without depolarizing the muscle or inhibiting cholinesterase activity.
