Description

Varenicline is a nicotinic receptor partial agonist—it stimulates nicotine receptors more weakly than nicotine itself does. In this respect it is similar to cytisine and different from the nicotinic antagonist, bupropion, and nicotine replacement therapies (NRTs) like nicotine patches and nicotine gum. Varenicline displays full agonism on α7 nicotinic acetylcholine receptors and is a partial agonist on the α4β2, α3β4, and α6β2 subtypes. In addition, it is a weak agonist on the α3β2 containing receptors. Varenicline's partial agonism on the α4β2 receptors rather than nicotine's full agonism produces less effect of dopamine release than nicotine's. This α4β2 competitive binding reduces the ability of nicotine to bind and stimulate the mesolimbic dopamine system—similar to the method of action of buprenorphine in the treatment of opioid addiction.

How to use

In Vitro:

Varenicline (CP 526555) (subcutaneous injection; 0.01, 0.05, 0.1 and 1 mg/kg; 3 days) iven 10 min prior to nicotine, inhibits nicotine CPP in a dose dependent manner. At the doses of 0.1 and 1 mg/kg totally blocks the effect of nicotine in CPP test without inducing significant changes in preferences on their own. Varenicline (2.5 mg/kg) results in a place aversion that was dependent on α5 nAChRs but not β2 nAChRs. Varenicline (0.1 and 0.5 mg/kg) reverses nicotine withdrawal signs such as hyperalgesia and somatic signs and withdrawal-induced aversion in a dose-related manner.
