This study was conducted to assess the clinical efficacy and adverse effects of pilocarpine, bethanechol and cevimeline in patients with xerostomia. In this open-label crossover assessment in 20 patients with xerostomia, a one- to two-week course of each medication with a one-week washout period was prescribed. Side effects, symptoms, whole stimulated and unstimulated saliva were measured. Each sialogogue was found to increase saliva and decrease symptoms. A mixed-effects analysis showed a greater increase in stimulated saliva on bethanechol compared to pilocarpine (0.106, p = 0.0272). Increased sweating was the most common side effect, experienced more frequently with pilocarpine as compared to bethanechol (p = 0.0588) or cevimeline (p = 0.0143). A carryover effect beyond the washout period was seen. Effects on saliva and side effects vary between sialogogues, suggesting a benefit of trials with different sialogogues to determine individual patient preference. The observed carryover effect suggests that intermittent treatment may be an alternative to continuous treatment with sialogogues.
