Ahmedabad-based Torrent Pharma is recalling nearly 74,000 bottles of its high blood pressure treatment tablets from the US and Puerto Rico. The US Food and Drug Administration (FDA) cited the presence of an impurity in the drugs above regulated daily intake level as the reason. The recalled batches were those of Losartan Potassium tablets and Losartan Potassium/Hydrochlorothiazide tablets.
