The aim of the present study was to compare the effect of low-dose pilocarpine and cevimeline as stimulants for salivary flow in healthy subjects.


In this cross-over clinical trial with a 1-week washout period, 40 male volunteers were submitted to an oral dose of pilocarpine 1% (Salagen) -60 microg kg(-1) body-weight (Group 1) or Cevimeline (Evoxac) -30 mg (Group 2). Saliva samples were collected and the salivary flow rate was measured (ml min(-1)) at baseline and 20, 40, 60, 80, 140 and 200 min after administration of drugs. In addition, salivary secretion was also measured under mechanical stimulation to observe salivary gland function.


The data were analyzed by Friedman and Wilcoxon signed-rank tests (significance level = 5%). Pilocarpine and cevimeline significantly increased salivary flow 140 min after intake. There was a significant higher secretion with cevimeline 140 and 200 min after administration. There were no differences seen among subjects in the salivary glands function by mechanical stimulation.


Both drugs showed efficacy in increasing the salivary flow in healthy volunteers, but cevimeline was more effective than pilocarpine.
