Reversal of cisplatin-induced delay in gastric emptying in rats by ginger ( Zingiber officinale)

Abstract

Cisplatin causes nausea, vomiting and inhibition of gastric emptying. We have demonstrated the antiemetic effect of the acetone and ethanolic extract of ginger ( Zingiber officinale, Roscoe, Zingiberacae) against cisplatin-induced emesis in dogs. In the present study, the acetone and 50% ethanolic extract of ginger in the doses of 100, 200 and 500 mg/kg (p.o.) and ginger juice, in the doses of 2 and 4 ml/kg, were investigated against cisplatin effect on gastric emptying in rats. All three ginger preparations significantly reversed cisplatin-induced delay in gastric emptying. The ginger juice and acetone extract were more effective than the 50% ethanolic extract. The reversal produced by the ginger acetone extract was similar to that caused by the 5-HT 3 receptor antagonist ondansetron; however, ginger juice produced better reversal than ondansetron. Therefore, ginger, an antiemetic for cancer chemotherapy, may also be useful in improving the gastrointestinal side effects of cancer chemotherapy.
