The FDA says a pharmaceutical company is voluntarily recalling a heart medicine after tests showed it was tainted with a potential cancer-causing chemical.

The pharmaceutical company, Sandoz, is recalling one lot of its losartan: Sandoz's losartan potassium hydrochlorothiazide 100 milligram/25 milligram tablets with the lot number JB8912.

The active ingredient in the drug tested positive for N-Nitrosodiethylamine or NDEA, a suspected human and animal carcinogen.

The drug is used by patients to keep their high blood pressure in check.
