To assess the effects of Persumac, a Persian herbal preparation, on refractory CINV.
Patients were randomized to two study sequence groups. One group received Persumac first and then placebo in crossover. The other group received the opposite sequence. Patients were entered in the second course of chemotherapy. Crossover was done in the third course of chemotherapy. Persumac and placebo were taken three times daily before meals. A washout period of six days was done prior to the third chemotherapy course. Patients were studied for 33 days. Patients recorded information about the severity and number of nausea and vomiting episodes on a visual analog scale and answered questions related to frequency of forgetting to take the study drug or other antiemetics. All patients received standard triple antiemetic regimens. Persuma included sumac and Bunium persicum.
PHASE OF CARE: Active anti-tumor treatment
Double blind, randomized, crossover clinical trial
VAS for nausea and vomiting (1-10 scale)
Average nausea severity was significantly lower during the period when using the persumac (p < 0.001), with reduction in at least two points on the VAS in the delayed phase compared to baseline results. There was no significant effect for acute phase CINV. The number of vomiting episodes was reduced. There were very few patients who had complete response for CINV (range = 0%-23%)
Persumac appeared to have some benefit in reduction of the severity of delayed CINV in this study.
Findings suggest that the Persian herbal medicine, Persumac, may have some benefit in reducing delayed CINV in women receiving moderate to severe emetic chemotherapy. Further evidence is needed to determine potential benefit.
