Rapid onset pulmonary fibrosis due to paraquat poisoning

Grammaxone (paraquat) is trade name for N,N'-dimethyl-4,4′bipyridinium dichloride. It is most widely used as herbicide. It came into disrepute because of accidental or intentional ingestion leading to a high mortality. Paraquat is commonly preferred for suicide by farmers because of easy availability, low cost, low toxic dose.
