Abstract
BACKGROUND: Xerostomia is the feeling of dryness in the mouth, usually owing to hypofunctioning of the salivary glands. Causes of xerostomia include medications, the effects of radiation therapy on the salivary glands during the treatment of head and neck cancer or thyroid cancer, and autoimmune diseases such as Sjögren's syndrome. The primary treatment to reduce xerostomia is oral pilocarpine. OBJECTIVE: This review discusses the randomized trials available on the efficacy and tolerability of oral pilocarpine for the treatment of xerostomia. METHODS: The randomized trials of pilocarpine for xerostomia available in the medical literature are reviewed. RESULTS/ CONCLUSION: Pilocarpine has some efficacy in the treatment of xerostomia from radiation therapy, graft-versus-host disease and Sjögren's syndrome. It has limited activity for the prevention of xerostomia during radiation therapy. It may have increased efficacy in combination with newer forms of radiation therapy.
