Article Description

Purpose Clozapine, a second-generation antipsychotic medication, is mainly indicated for managing treatment-resistant schizophrenia. Among all the nonthreatening adverse effects of clozapine, sialorrhea is a stigmatizing complication occurring in approximately 31.0% to 97.4% of patients. In this study, 2 topical agents (atropine eye drop and ipratropium nasal spray) and a systemic medication (amitriptyline) were compared simultaneously for the management of clozapine-associated sialorrhea. Methods We conducted a randomized, single-blinded, non-placebo-controlled clinical trial from June 2022 to January 2023. Eligible patients were randomly allocated into 3 mentioned groups. Patients were monitored for sialorrhea weekly based on scales, including the Toronto Nocturnal Hypersalivation Scale, Clinical Global Impression-Improvement, and Clinical Global Impression-Severity for 1 month. Possible adverse drug reactions and adherence were also recorded. Results Twenty-four patients, including 6, 10, and 8 individuals in ipratropium bromide nasal spray, atropine eye drop, and amitriptyline groups, completed the study, respectively. The cohort's demographic, baseline clinical, and sociocultural characteristics were comparable among the 3 groups. Within-group comparisons, between times baseline and week 4, demonstrated that significant differences were in groups atropine and amitriptyline based on Toronto Nocturnal Hypersalivation Scale, in 3 groups based on Clinical Global Impression-Improvement, and also in only-atropine group based on Clinical Global Impression-Severity. Likewise, between-group comparisons showed that atropine was significantly more effective in clozapine-associated sialorrhea management than amitriptyline and ipratropium, in the first 2 weeks and second 2 weeks of study, respectively. Regarding safety, the interventions were tolerated relatively well. Conclusions Conclusively, atropine is more efficacious than amitriptyline, within the first 2 weeks of study and also relative to ipratropium, overall. As time effect was significant between atropine and amitriptyline, according to analysis of covariance test, further investigation with longer follow-up duration would be prudent. In addition, expanding patient population with larger sample size should be conducted for more precision.
