Abstract
Background. Tropisetron (ICS 205–930) antagonizes the serotonin type 3 receptor and has antiemetic activity in animals given cisplatin. Its mean serum half‐life is 11.1 hours. Methods. In this dose‐ranging trial, 22 patients undergoing anti‐cancer chemotherapy received 24 courses of a single intravenous infusion of tropisetron beginning 30 minutes before chemotherapy. Four dose levels were explored (range, 12–48 mg/m2). Results. Toxicities were mild and included headache, transient elevations of serum alanine transaminase and/or aspartate transaminase levels, and sedation. No akathisia or acute dystonic reactions were observed. Thirty‐six percent of patients had no emesis, and 58% had two or fewer emetic episodes. Ten patients received high‐dose cisplatin (dose, ⩾ 100 mg/m2) as initial chemotherapy. Of these, 30% had no emesis, and 60% had two or fewer episodes. Conclusions. Tropisetron can be administered safely in the doses tested with no dose‐limiting toxicities. The encouraging antiemetic efficacy, mild toxicities, lack of extrapyramidal effects, and convenience of a single 15‐minute infusion regimen make this drug appropriate for study in additional trials.
