Whicm among the following doe not cause hyperpyrexia? 
Select and explain. 
A. MAGI, B. Alcohol, C. Atropine, D. Amphetamine
B: Alcohol
Answer: B: Alcohol 
Explanation: B i.e. Alcohol Alcohol (methyl and ethyl) causes hypothermia (not hypehermia) and peripheral vasodilationQ. Peripheral vasodilatation increases peripheral circulation resulting in feeling of warmth and warm skin, but at the same time actually there is loss of body heat from skin resulting in hypothermia. This becomes very impoant in cold temperatures. Antidepressants (such as amphetamine, MAO-inhibitors and tricyclic antidepressants) and atropine all have anticholinergic effects causing hyperpyrexiaQ.
