Combination Therapy with Granisetron, Methylprednisolone and Droperidol as an Antiemetic Prophylaxis in CDDP-Induced Delayed Emesis for Gynecologic Cancer

Abstract

Objective: To better control both acute and delayed emesis resulting from cisplatin(CDDP)-based chemotherapy for gynecological malignancies, we designed a ‘cocktail therapy’ (CCT) using granisetron (GRN) in combination with methylprednisolone (MPD) plus droperidol (DRP). Methods: Two crossover clinical trials were carried out to compare the efficacy and safety of (a) GRN alone (3 mg/patient) with that of GRN, MPD (250 mg/patient) and DRP (0.5 ml/patient) in 42 patients (CCT group) and (b) GRN and MPD (CMB group) with that of the CCT group in 27 patients during the first 7 days of chemotherapy, independent of the weight/body surface of the patients. One of these regimens was administered intravenously for the first 3 days of chemotherapy, in case of failure for a maximum of 5 days. Results: For acute emesis, complete protection from nausea and vomiting by the end of the 1st day was achieved in 64.3% receiving GRN and in 92.9% receiving CCT (p < 0.01). For delayed emesis, complete protection was best achieved in CCT on days 2–3, showing statistical significance compared to GRN treatment (p < 0.01). Comparing the three kinds of treatment during 7 days, the lowest protection was 38.1% in the GRN group, 51.9% in the CMB group and 72.5% in the CCT group, especially on days 2 or 3. Conclusions: The CCT combination is useful for the control of delayed and/or anticipatory emesis resulting from CDDP-based chemotherapy for women with gynecological malignancies.
