In a double-blind, randomised, multicentre study, the efficacy and tolerability of tropisetron and a combination of tropisetron and dexamethasone were compared for the control of nausea and vomiting induced by cisplatin in patients previously not entirely protected by tropisetron monotherapy. In all, 160 women with gynaecological cancers were studied during two consecutive courses of cisplatin-containing chemotherapy. During the first course (the screening course), all patients received tropisetron monotherapy [5 mg intravenous (i.v.) on day 1 and 5 mg orally on days 2-6] as antiemetic treatment. During the second course (the test course), tropisetron was compared with a combination of tropisetron and dexamethasone (20 mg i.v. on day 1 and 4.5 mg twice daily on days 2-6). This part of the study was double-blind, randomised and placebo-controlled. Candidates for randomisation were patients with partial control of nausea (< 12 h of nausea) or partial control of vomiting (1-4 episodes of vomiting) during the screening course. Patients with complete control of nausea and vomiting in the screening course continued with tropisetron monotherapy; patients with treatment failure received open rescue treatment in course 2. Total control of acute nausea was achieved in 37% of the tropisetron + placebo group and in 75% of the tropisetron + dexamethasone group (P = 0.001). Significantly more patients on tropisetron-dexamethasone than on tropisetron-placebo were also free of delayed nausea. Acute vomiting was prevented in 40% of the patients in the placebo group and in 75% in the dexamethasone group (P = 0.001). Delayed vomiting was also significantly less frequent in dexamethasone-treated patients than in placebo-treated patients. Tropisetron was well tolerated both as monotherapy and in combination with dexamethasone. The most frequent adverse events were headache (34%), constipation (12.5%) and fatigue (12.5%). Adding high doses of a corticosteroid did not induce further adverse events or disregulate concurrent diseases.

We report an open, three-armed, multicenter study being carried out to assess the optimum treatment for acute and delayed emesis and nausea in patients undergoing highly emetogenic chemotherapy. Eighty-seven patients were randomized to receive tropisetron (Navoban; Sandoz Pharma Ltd, Basel, Switzerland), tropisetron plus dexamethasone, or tropisetron plus metoclopramide during chemotherapy. Tropisetron in combination with dexamethasone produced the best control of both acute and delayed emesis. Acute vomiting was prevented in 69% of patients by tropisetron monotherapy, and the addition of dexamethasone significantly increased the total control of vomiting to 92% (P < .01). Similarly for delayed vomiting, total control of emesis was seen in approximately 70% of patients on tropisetron alone during days 2 and 3; this control rate increased to almost 90% with combined tropisetron/ dexamethasone treatment. In all patients receiving cisplatin, the tropisetron/dexamethasone combination produced total control of acute emesis. The tropisetron and dexamethasone combination also provided the best control of acute and delayed nausea. Tropisetron produced total control of acute nausea in 69% of patients. The addition of dexamethasone increased this control rate to 81%. Similarly for delayed nausea, on days 2 and 3 of treatment, dexamethasone plus tropisetron provided total control of nausea in more than 80% of patients compared with a control rate of more than 60% achieved using tropisetron. The combination of tropisetron and metoclopramide did not improve significantly on the control of nausea and vomiting achieved using tropisetron alone. Evaluation of quality of life events by patients indicated no appreciable change in their mental or physical condition during chemotherapy, irrespective of antiemetic therapy. In the tropisetron and tropisetron plus metoclopramide treatment groups, a decreased food intake was observed due to delayed nausea while the addition of dexamethasone prevented loss of appetite. The antiemetic treatments were similarly well tolerated. The most common adverse events were constipation (15%) and tiredness (7%).
