Abstract:
Organophosphate (OP) compounds are commonly ingested with the intention of deliberate self-harm. Parenteral route of OP compound exposure is an uncommon yet significant source of toxicity. Deliberate injections via intravenous, intramuscular, and subcutaneous routes and accidental dermal absorption due to occupational exposure have been described earlier. We report an unusual case of intentional insecticide poisoning by pouring the OP compound into both ears. This was successfully treated with aural irrigation using normal saline and prompt administration of the antidote.

Additional Routes of Drug Administration
Administering drugs via inhalation allows for the direct delivery of gaseous, volatile substances or droplets to different parts of the respiratory tract. One of the advantages of the inhalation route is the rapid absorption of drugs into the circulatory system, which is possible because of the large surface area of...

Routes of Drug Administration: Parenteral
The intravenous route (IV) of drug administration can be further categorized into two types. The bolus injection administers the entire dose rapidly, while an intravenous infusion slowly delivers smaller doses steadily.
The IV route is often...
