The anti-emetic efficacy of a combination of tropisetron and dexamethasone
was studied in 33 patients who underwent bone marrow transplantation.
Another 50 patients receiving conventional anti-emetic therapies in bone
marrow transplantation served as control. On the first and second days of
preconditioning chemotherapy, 51% and 36% respectively of patients in the
tropisetron and dexamethasone group did not experience vomiting, compared
with only 12% and 10% of control group patients (P < 0.001). The mean
number of episodes of vomiting in the tropisetron and dexamethasone group
was also significantly lower than in the control group (0.97+/-1.65 vs
3.50+/-2.45 and 1.30+/-1.40 vs 4.44+/-2.91 respectively, both P <
0.001). Control of vomiting in the two groups was not significantly
different during days 3-6. Analysis of patients receiving busulfan and
cyclophosphamide as the preconditioning regimen still showed better
anti-emetic control in the tropisetron and dexamethasone group than in the
control group on the first two days of treatment (total control rate 33.3%
vs 6.5% and 44.4% vs 12.9% respectively, P < 0.001). Patients given
tropisetron and dexamethasone combination more frequently suffered from
dizziness and burning sensation of the chest. However, diarrhea and
extrapyramidal symptoms were the most frequent adverse effects seen after
using conventional anti-emetic combination. The combination of tropisetron
and dexamethasone was thus superior to conventional anti-emetic
combinations in preventing vomiting during preconditioning period of bone
marrow transplantation. The adverse effects of this combination were
minimal and well tolerated by patients.
