[Sucralfate in odontostomatology. Clinical experience].

BACKGROUND: We here describe the pharmacological and pharmacodynamic characteristics of the molecule sucralfate, the aluminum subsalt of sucrose-8-sulphate, introduced in Japan in 1968 as a mucoprotector for the treatment of peptic ulcers. For many years, attempts have been made to broaden the therapeutic indications of this molecule as has happened in oral medicine. This paper describes the results of the clinical trials reported in the international literature which were designed to investigate the use of sucralfate in the treatment of mucositis secondary to radio- and/or chemotherapy and during the course of recurrent aphtous stomatitis (RAS).

METHODS: The authors carried out a pilot study with the aim of testing the efficacy and the tolerability of two formulations of sucralfate (20% suspension and 1 gram chewable tablets) in a total of 28 patients [14 with RAS: group A; and 14 with burning mouth syndrome (BMS): group B]. Each group was further divided into two subgroups [A1, A2, B1, B2] of 7 patients each.

RESULTS: The results obtained in the RAS patients were encouraging, with an improvement in symptomatology in respectively 71.4% and 42.8% of the patients in subgroups A1 and A2; a number of authors have previously suggested that this is due to a primarily mucoprotective mechanism similar to that occurring in patients with peptic ulcer. The results were less favourable in the BMS patients: symptoms improved in respectively 42.8% and 28.6% of the patients in subgroups B1 and B2, but worsened in 28.6% and 28.6% in teh same subgroups.

CONCLUSIONS: In conclusion we believe that sucralfate can be considered a valid therapeutic support in the context of the lenitive pharmacological protocols in which it is currently used, but our results do not allow a definitive judgement of its efficacy in patients with BMS.
