Varenicline (CP 526555) is a selective α4β2 nicotinic receptor partial agonist, it stimulates nicotine receptors more weakly than nicotine itself does. Varenicline is a full agonist for α3β4 and α7 nAChRs with EC50 values of 55 μM and 18 μM, respectively.
| Cell Experiment | |

| Cell lines | MS/DB neurons |
| Preparation method | In one subset of experiments, bath solution containing nicotine (10 μM) was initially applied followed by a nicotine (10 μM) plus varenicline (10 μM) bath solution. For a second subset of experiments, the order of drug application was reversed with a varenicline (10 μM) containing bath solution applied first followed by a varenicline (10 μM) plus nicotine (10 μM) bath solution. |
