  • Purpose: Pilocarpine as a salivation stimulant in pill form has mostly been used to relieve oral dryness for xerostomic patients but its use may often be limited due to variable side effects from systemic absorption. Therefore, the purpose of this study was to investigate the effects of pilocarpine mouthwash on salivation according to the variable concentration and duration for healthy volunteers. Related adverse effects and subjective assessment on its effects on salivation were also examined. Methods: This study was performed as placebo-controlled, double-blind, randomized clinical trial. Thirty healthy volunteers (male=23, mean age=22.2 years) were randomly allocated to 6 groups with the different concentration of pilocarpine mouthwash (placebo, 0.1%, 0.5%, 1.0%, 1.5%, and 2.0%). The whole experiment consisted of 3 sessions according to the duration of mouthwash, i.e., 1, 3, and 5 minutes with the mean wash-out period ${\geq}2$ days between the sessions. Unstimulated whole saliva was collected before and after gargling with a mouthwash. Results: Salivation of the higher concentration groups ${\geq}1%$ significantly increased than those of lower concentration group. The application period of mouthwash did not cause any changes of salivary flow rate at the higher concentrations ${\geq}1.0%$. The lower concentrations of 0.5% and 0.1% had no effects on salivation even after 5-minute mouthwash. There was no significant difference between blood pressure and pulse rate before and after use of mouthwash. Conclusions: From the results of the current study, pilocarpine mouthwash with at least 1.0% concentration more than a minute might be clinically effective in salivation without any serious side effects. Dose of mouthwash rather than duration seems to be a critical factor to salivation.

  • Purpose: Pilocarpine has the effects on improvement of salivary flow and subjective symptoms for xerostomic patients. Because of unwanted side effects following its systemic administration, topical pilocarpine has been paid attention as an alternative. This study aimed to investigate effects of pilocarpine solution as mouthwash on salivary flow and adverse effects compared to systemic administration of 5 mg pilocarpine tablet in healthy subjects. Methods: The study was a double blind, placebo-controlled, crossover clinical trial. Five milligrams pilocarpine tablets, 4 mL of 2% pilocarpine solution and placebo solution were given to 12 healthy volunteers (6 males and 6 females) in a predetermined order with wash-out period of at least two days and unstimulated whole saliva was collected before and after administration of each drug. Blood pressure and pulse rate was also measured and subjective effect and potential side effects were evaluated by a self-administrated questionnaire. Results: Systemic (5 mg tablet) and topical (2% solution) use of pilocarpine significantly increased salivary flow rate in healthy subjects compared to placebo (p<0.001). In both the pilocarpine solution and tablet groups, salivary flow rates at 120 minutes after administration remained increased. Subjective effect on salivation was the largest in the pilocarpine tablet group, followed by the pilocarpine solution group (p<0.05). There was no significant difference in blood pressure and pulse rate after administration of all three drugs. Fewer side effects reported in the pilocarpine solution group than in the tablet group. Conclusions: Two percents pilocarpine solution as mouthwash increases salivary flow rate, definitely superior to placebo solution and comparable to pilocarpine tablet, with fewer side effects in healthy subjects. It indicates a possibility of pilocarpine solution as a useful alternative of pilocarpine tablets for the xerostomic patients with systemic diseases.

  • Xerostomia is subjective feeling of dry mouth, a symptom that may or may not be accompanied by hyposalivation, an objective decrease in salivary flow. There are many causes induced xerostomia like drugs, salivary gland diseases, radiation therapy to the head and neck region, Sjogren syndrome, emotional stress etc. Insufficient salivary flow creates complications with oral candidiasis, dental caries, periodontitis, halitosis, dysgeusia. So finally, these complications lead to an overall decline in quality of life. Managements of xerostomia are eliminating or alterating the etiologic factors, relieving symptoms, preventing or correcting the consequences of salivary dysfunction, treating underlying disease and stimulating salivation. One of the salivation stimulation agents studied to treat xerostomia was the pilocarpine muscarinic agonist. Pilocarpine is one of salivation stimulants, a parasympathomimetic drug and non-selective muscarinic receptor agonist. Systemic pilocarpine has been used to stimulate salivary secretion. But systemic administration of pilocarpine has limitations such as increased risk of side effects and contraindications. Side effects of systemic pilocarpine administration are sweating, urinary and gastrointestinal disturbance, risk of cardiovascular and pulmonary disorders. This drug must be used carefully by patients with controlled asthma, chronic bronchitis, pulmonary or cardiac disease. Patient with acute asthma, narrow angle glaucoma, iritis should not use pilocarpine. Like this, systemic pilocarpine has many limitations. So, many investigators also have looked at the effectiveness of topical pilocarpine. Here we present patients with xerostomia which was relieved by pilocarpine mouthwash.
