The expanded recall includes an additional three lots of losartan potassium tablets USP and two lots of losartan potassium/hydrochlorothiazide tablets.
The impurity is N-Methylnitrosobutyric acid. Torrent is recalling only lots of losartan NMBA above the acceptable daily intake levels released by the FDA.
Losartan belongs to a class of medicines used for treating high blood pressure called angiotensin II receptor blockers. Some generic versions of other ARBs, such as valsartan and irbesartan, have also been recalled.
Losartan is used to treat hypertension, hypertensive patients with left ventricular hypertrophy and for the treatment of nephropathy in type 2 diabetic patients. Losartan potassium and hydrochlorothiazide tablets, USP are used to treat hypertension and hypertensive patients with left ventricular hypertrophy.
To alleviate shortages caused by these recalls, the FDA in March approved a generic form of the blood pressure medication Diovan, or valsartan.
If you were prescribed the medications above, the Food and Drug Administration recommends you continue taking them until an alternative treatment is in place, because, "The risk of harm to the patient's health may be higher if the treatment is stopped immediately."
