Miconazole mucoadhesive buccal tablet in high-dose therapy with autologous stem cell transplantation (HDT/ASCT)-induced mucositis.

Oral mucositis is a major cause of morbidity in high-dose therapy/autologous stem cell transplantation (HDT/ASCT), where microbial colonization has an important pathological implication. In this study, we evaluated the impact of miconazole mucoadhesive buccal tablet (MBT) on mucositis-related complications. During two consecutive 34-month periods, patients treated with HDT/ASCT in our hematology department received either miconazole MBT (60 patients) or conventional oral amphotericin B suspensions three times a day (44 patients) in order to prevent or decrease chemotherapy-induced mucositis. The use of miconazole MBT is associated with less infectious complications as indicated by shorter antibiotic use (7.8 vs. 12.3 days; p < 0.0001), shorter intravenous antifungal use (1.4 vs. 3.6 days; p = 0.02), and a trend towards less yeast contamination in stool samples. Less patients required any analgesic drugs during hospitalization in the miconazole MBT group (18 vs. 7 %; p = 0.09). Indirect indicators of chemotherapy-induced mucositis (duration of hospitalization, morphine use) were in favor of miconazole MBT in patients with multiple myeloma (MM) but not for those with lymphoma. This study suggests that miconazole MBT provides a valid alternative to oral amphotericin B suspensions in regards to mucositis-related complications. A prospective and randomized study is warranted to establish the definite role of miconazole MBT.
