| Definition (MSH) | A wide spectrum aliphatic organophosphate insecticide widely used for both domestic and commercial agricultural purposes. |
| Definition (NCI) | A synthetic phosphorous compound and cholinesterase inhibitor that is strictly used as a topical pediculicide. Malathion exerts its action on the nervous system of the lice by irreversibly inhibiting the activity of cholinesterase, thereby allowing acetylcholine to accumulate at cholinergic synapses and enhancing cholinergic receptor stimulation. This eventually leads to the head lice's death. |
