Indisetron Hydrochloride

We set out to determine the efficacy of indisetron hydrochloride for the management of chemotherapy-induced nausea and vomiting including carboplatin for lung cancer. Indisetron hydrochloride was given orally to 32 patients (indisetron group), and intravenous 5-HT3 receptor antagonists were given to 24 patients (control group). The number of patients with nausea or vomiting occurring within 24 hours and 24 to 72 hours after chemotherapy was measured. The complete inhibition of the vomiting within 24 hours after chemotherapy was 100% in the indisetron group and 95.8% in the control group. Twenty-four to 72 hours after chemotherapy, the complete inhibition of vomiting rate was 97.1% and 95.8%, respectively. In addition, the complete inhibition of nausea rate within 24 hours after chemotherapy was 87.5% in the indisetron group and that was 95.8% in the control group. The complete inhibition of nausea rate 24 to 72 hours after chemotherapy was 56.3% and 70.8%, respectively. No serious adverse events were observed. The comparison of the efficacy between the indisetron group and control groups did not reach statistical significance (p> 0.05). These findings suggest that prophylactic administration of indisetron hydrochloride is useful for the inhibition of acute and delayed nausea and vomiting caused by chemotherapy in lung cancer patients.

This clinical trial was designed to evaluate the efficacy and safety of indisetron hydrochloride an oral 5-HT3 receptor antagonist, for the management of nausea/vomiting caused by chemotherapy for gynecologic cancer with paclitaxel/ carboplatin or docetaxel/carboplatin. Indisetron hydrochloride(8 mg)was administered orally to 46 gynecologic cancer patients at 0.5 hours before administration of the above chemotherapy agents. Number of patients who showed nausea or vomiting for 24 hours was counted. The complete vomiting inhibition rate at 24 hours after chemotherapy was 89.1%(41/46), and nausea inhibition rate was 71.7%(33/46). No serious adverse events were observed. These findings indicate that prophylactic administration of indisetron hydrochloride is safe and useful for inhibition of nausea/vomiting caused by cancer chemotherapy.
