Randomized crossover study of the antiemetic activity of levonantradol and metoclopramide in cancer patients receiving chemotherapy.

In a randomized crossover study 57 cancer patients receiving chemotherapy with high emetic potential were treated with low-dose levonantradol or standard-dose metoclopramide and crossed over to the other antiemetic drug in the next identical chemotherapy cycle. In the 45 patients evaluable for treatment response the antiemetic efficacy of levonantradol was significantly better: 62% had less nausea and 58% less vomiting, as against 11% and 16%, respectively, with metoclopramide. Patient preference for antiemetic treatment was levonantradol in 49% and metoclopramide in 22% of cases. Levonantradol treatment was accompanied by a relatively high incidence of side-effects (71%) compared with metoclopramide (29%). The antiemetic efficacy of each single drug was incomplete in most cases of this trial, and antiemetic combination therapy is recommended for further trials.
