The Cytisinicline Difference Dual-Acting, Highly-Targeted MOA  Single & Short Treatment Very Well-Tolerated ACHIEVE LIFE SCIENCES 11

 


 


 

 

 

Dual-Acting MOA Specifically Targets α4β2 Nicotine Receptors Activity 1: Partial Agonist Cytisinicline binds to the receptor partially stimulating dopamine release Reduces nicotine cravings Reduces the severity of withdrawal symptoms Activity 2: Partial Antagonist Cytisinicline binding to the receptor prevents the binding of nicotine Removes the nicotine-induced reward and satisfaction associated with smoking Activation of the central nervous mesolimbic dopamine system is believed to be the neuronal mechanism underlying reinforcement and reward experienced by smoking ACHIEVE LIFE SCIENCES 12
