Objective:
We compared the effects of haloperidol and three atypical antipsychotics (risperidone, olanzapine, and aripiprazole) on nicotine dependence in schizophrenic patients.
Methods:
One hundred and thirty nine schizophrenic patients, who began using antipsychotic medication, were assessed for severity of nicotine dependence and for cigarette craving at baseline and following 8 weeks of treatment using the Fagerström Tolerance Questionnaire (FTQ) and a Likert-style, seven point, visual-analogue rating scale.
Results:
Nicotine dependence increased in the haloperidol group, but not in atypical antipsychotics groups. Patients treated with aripiprazole showed a reduction both in nicotine dependence and cigarette craving.
Conclusions:
The effects of aripiprazole, a partial agonist of the dopamine D2 receptor, may reduce the severity of nicotine dependence in schizophrenic patients.

Drugs Acting on Autonomic Ganglia: Stimulants
Ganglionic stimulants activate NM nicotinic receptors in autonomic ganglia, falling into two categories: nicotine mimetics [e.g., lobeline, dimethylpiperazine, tetramethylammonium] and muscarinic receptor agonists [e.g., muscarine, methacholine]. The first category's action is rapid and blocked by nicotinic receptor antagonists, while the second category's action is delayed and blocked by atropine-like agents. Nicotine, an alkaloid, affects the heart rate by stimulating sympathetic or...

Drug-Receptor Interaction: Agonist
Agonists can bind to receptors in different ways. Some agonists bind directly to the receptor's active site, mimicking the endogenous ligand's action.
