Years ago ipecac syrup was used to induce vomiting in poisoning cases. Now a Loyola University Medical Center study has found that the active ingredient of ipecac syrup effectively inhibits the growth of bladder cancer cells, especially when combined with a standard chemotherapy drug.
The study by corresponding authors Kimberly Foreman, PhD; Gopal Gupta, MD; and colleagues is published online ahead of print in The Journal of Urology.
The active ingredient of ipecac syrup comes from the flowering plant Psychotria ipecacuanha. The drug no longer is recommended to induce vomiting. Studies have shown that vomiting after swallowing poison does not help and sometimes can be harmful. Moreover, ipecac syrup can be abused by people with eating disorders.
Two small studies published in 1969 and 1970 found that the active ingredient of ipecac syrup, emetine dihydrochloride, helped in treating bladder cancer. Recent studies have found emetine also can kill leukemia cells.
In the new study, Loyola researchers exposed cell lines of normal and cancerous bladder cells to emetine alone and to emetine plus cisplatin. (Cisplatin is the standard chemotherapy drug for advanced bladder cancer.)
The study found, for the first time, that:
Bladder cancer is the fourth most common cancer in men and the 9th most common cancer in women. But even with aggressive surgery and chemotherapy, the five-year survival rate for patients with advanced Stage 4 bladder cancer is only 4 to 20 percent.
"There is an urgent need to develop new drug combinations," Dr. Gupta said. "Our study demonstrates that combining emetine with cisplatin is potentially beneficial and merits further study in clinical trials."
Dr. Gupta is an assistant professor in the departments of Urology and Surgery and in the Oncology Research Institute of Loyola University Chicago Stritch School of Medicine. Dr. Foreman is an associate professor in the Department of Pathology and the Oncology Research Institute. Other authors are John Jesse III, a Stritch student, and Paul Kuo, MD, FACS, chair of Loyola’s Department of Surgery and director of the Oncology Research Institute.
