 Eflornithine (CAS NO.70052-12-9) is a drug manufactured by Sanofi-Aventis that has various uses. A recent study (reported 2008 ) conducted by UC Irvine researchers indicates that, when combined with sulindac , Eflornithine significantly reduces the risk of recurring colorectal polyps. It was initially developed for cancer treatment, but, while having little use in treating malignancies. In the United States it is known by the brand name Ornidyl.

 Eflornithine (CAS NO.70052-12-9), its production was halted by its manufacturer, Aventis, in 1995 because the company did not consider it a profitable drug. In 2001, after lobbying at the WHO World Health Organization by Médecins Sans Frontières ("Doctors Without Borders"), the manufacturer resumed production of eflornithine, melarsoprol, and pentamidine in sufficient amounts to cover existing needs. As of September 2005, the World Health Organization reports that the India Institute of Chemical Technology in Hyderabad, India and ILEX Oncology in Texas, United States are both working on new ways of making eflornithine more cheaply.

 Human systemic effects by intravenous route: cardiomyopathy, pulse rate decrease, fall in blood pressure. An experimental teratogen. Other experimental reproductive effects. Mutation data reported. When heated to decomposition it emits toxic fumes of F⁻ and NO_x.

 Eflornithine , its cas register number is 70052-12-9. It also can be called Difluoromethylornithine ; Ornidyl ; Ornithine, 2-(difluoromethyl)- and a-Difluoromethylornithine .
