Question

A patient from a railway station is arrested by police and shows symptoms like dilated pupils, sweating, hot skin, and staggering gait. He is suspected to have intoxication from:

• A. Dhatura
• B. Cocaine
• C. Alcohol
• D. Morphine

Hint:

Dhatura poisoning is characterized by anticholinergic symptoms, including dilated pupils, dry skin, and altered mental status.

Answer 1

The Correct Option is A

Step 1: Group the symptoms into a toxidrome.
Dilated pupils (mydriasis), sweating yet hot, flushed skin, and an unsteady staggering gait point to an anticholinergic state - a substance blocking acetylcholine, producing the classic "hot as a hare, dry/flushed, blind as a bat, mad as a hatter" picture with ataxia.

Step 2: Match the toxidrome to the agent.
Dhatura (Datura) seeds contain tropane alkaloids - atropine, scopolamine (hyoscine) and hyoscyamine - which are potent muscarinic antagonists. They reproduce exactly this combination: mydriasis, hot flushed skin, agitation/delirium and an unsteady gait. Such poisonings are well documented in railway-station "road-side poisoning" robberies, fitting the scenario.

Step 3: Eliminate the other options.
• Cocaine - a sympathomimetic; it dilates pupils but typically gives tachycardia, hypertension and euphoria rather than this full anticholinergic gait/skin picture.
• Alcohol - causes a staggering gait but usually does not dilate pupils or give hot, dry skin.
• Morphine - an opioid producing pinpoint (constricted) pupils and CNS/respiratory depression, the reverse of mydriasis here.

Step 4: Conclude.
Only Dhatura explains every feature through its anticholinergic alkaloids.

Final answer: Option 1 - Dhatura.
