UNLABELLED: <p>Introduction: The purpose of this study was to evaluate the effect of biperiden on nicotine craving in a proof-of-concept clinical study.
METHOD: The study involved 46 male participants (mean age: 45.3 ± 9.31 years) who smoked an average of 20.8 (10.0) cigarettes per day. Participants were randomly assigned to either a biperiden (4 mg/day) or placebo group, with treatment lasting 7 days. The outcomes were assessed at baseline (T0) and after 7 days (T1) using self-reported questionnaires, including the Questionnaire of Smoking Urges-Brief, the Fagerström Tolerance Questionnaire, and the Beck Anxiety and Depression Inventories.
RESULTS: Repeated measures ANOVA revealed a significant time × treatment interaction between cigarette consumption (p < 0.001, <inline-formula><mml:math id="m1" xmlns:mml="http://www.w3.org/1998/Math/MathML"><mml:mrow><mml:msubsup><mml:mi>η</mml:mi><mml:mi mathvariant="normal">p</mml:mi><mml:mn>2</mml:mn></mml:msubsup></mml:mrow></mml:math></inline-formula> = 0.340) and craving (p = 0.002, <inline-formula><mml:math id="m2" xmlns:mml="http://www.w3.org/1998/Math/MathML"><mml:mrow><mml:msubsup><mml:mi>η</mml:mi><mml:mi mathvariant="normal">p</mml:mi><mml:mn>2</mml:mn></mml:msubsup></mml:mrow></mml:math></inline-formula> = 0.203), indicating that participants in the biperiden group showed greater reductions than those receiving placebo. For dependence, anxiety, and depression, only the main effect of time was significant (p < 0.05), suggesting general improvement across both groups. Ethnicity did not significantly influence any outcomes, and no relevant adverse effects were reported.
CONCLUSIONS: These findings suggest that biperiden may represent a promising pharmacological approach for reducing nicotine craving. Further studies with prolonged administration are warranted to evaluate its therapeutic potential for smoking cessation. </p>.
