FDA once again expands recall of blood pressure drugs

The Food and Drug Administration has once again expanded its recall of widely prescribed blood pressure drugs because of contamination with a chemical linked to cancer.

The latest recall, announced Wednesday (June 23), targets 32 lots of the drug losartan sold by Macleods Pharmaceuticals. The pharmaceutical company said that it would voluntarily recall the affected batches.

Losartan is a generic angiotensin II receptor blocker, or ARB, and is used to treat high blood pressure as well as heart failure. Over the last year, scores of batches of generic ARBs have been withdrawn from the market due to the presence of chemical contaminants called nitrosamines, which have been linked to an increased risk of certain kinds of cancer.
