A sialogogue, sialagogue, or ptyalagogue is a drug or substance that increases the flow rate of saliva. Sialogogues can be used in the treatment of xerostomia, to stimulate any functioning salivary gland tissue to produce more saliva. Saliva has a bactericidal effect, so when low levels of it are secreted, the risk of caries increases. Not only this, but fungal infections such as oral candidosis also can be a consequence of low salivary flow rates. The buffer effect of saliva is also important, neutralising acids that cause tooth enamel demineralisation. The following are used in dentistry to treat xerostromia: ⁕Parasympathomimetic drugs act on parasympathetic muscarinic receptors to induce an increased saliva flow. The M3 receptor has been identified as the principle target to increase salivary flow rates. Pilocarpine is an example; the maximum dose of this drug is 30 mg/day. Contraindications include many lung conditions, such as asthma, cardiac problems, epilepsy and Parkinson's disease; side effects include flushing, increased urination, increase perspiration, and GI disturbances. ⁕Chewing gum induces stimulated saliva secretion of the minor salivary glands in the oral cavity. During mastication, the resultant compression forces acting on the periodontal ligament cause the simulated release of gingival crevicular fluid. Further salivation can be also achieved by the stimulation of taste receptors.
