| Notes |
- Synthetic derivatives of phosphoric acid. Used as pesticides, primarily
as agricultural insecticides.
- Used extensively as topical ectoparasiticides and systemic anthelmintics.
- Interfere with cholinergic nerve transmission. Inhibit the activity of
cholinesterase enzymes responsible for hydrolysis of the neurotransmitter acetylcholine at
nerve endings, by competing with acetylcholine for binding sites. Acetylcholine builds up
in the synaptic cleft, resulting in continuous firing of the neuron. Rate of reaction with
the enzyme days to months for organophoshates, compared with less than one second for
acetylcholine.
- Relatively short-lived in the environment, but organophosphates have a
longer duration of action than carbamates
(days to months, rather than hours to days) and can become irreversibly bound to
cholinesterase receptors (process known as aging).
