Torrent Pharmaceuticals Limited has again expanded a recall of its blood pressure medication over concerns the tablets contain small amounts of a cancer-causing ingredient. The Food and Drug Administration (FDA) announced Torrent Pharmaceuticals Limited voluntarily expanded the recall to include additional lots of its Losartan Potassium Tablets USP and Losartan Potassium/hydrochlorothiazide tablets. It is used to treat hypertension, hypertensive patients with Left Ventricular Hypertrophy, and nephropathy in Type 2 diabetic patients. The ingredient detected in the tablets was identified as N-Methylnitrosobutyric acid (NMBA), a known animal and potential human carcinogen. The news marks the fifth time the company has expanded the recall.
