Abstract

Cyclic antidepressants are still a dominating group of psychotherapeutic drugs used in the treatment of depression. One of their major side effect is salivary gland dysfunction (oral dryness, xerostomia), leading in humans to increased oral disease and dysfunction of speech, chewing, swallowing and taste. The purpose of this study was to assess the effects of the long-term administration of the tricyclic antidepressant desipramine and the reversibility of this treatment following a 15 d washout period on specific salivary proteins, composition of oral microbiota, and oral health (gingivitis) of aging female F344 rats. Total salivary proteins showed decreased concentrations with age and desipramine. Similar SDS/PAGE protein profiles appeared in all phases but in different relative amounts with age and treatment. While certain proteins maintained steady levels (lactoferrin) or decreased with age and treatment (amylase), the synthesis of proline-rich proteins, high molecular weight mucin-type glycoproteins, and lysozyme was induced with desipramine and age. The oral microbiota was significantly changed with age and the administration of the antidepressant. The incidence of gingivitis with desipramine was highest in the oldest animals, For the different parameters measured, recovery was delayed with age. These data indicate, that desipramine has profound effects on salivary protein secretion. This may partially explain the changes in microbiota and the increased incidence of gingivitis.
