Patient came with palpitation, muscle weakness, fever, mydriasis, dry mouth.
Which of the following drugs might the patient has taken?
a- atropin
b- ephedrin
c- botulinum toxin
d- edrophonium
e- benztropine

 

[khanar]

These are signs of anticholinergic toxicity
Is is the answer Atropin?

 

[khanar]

No, Atropin does not cause muscle weakness

The correct answer is Botulinum toxin, as it will destruct the ACh vesicles in all the synapses including the nicotinic ones not only the muscarinic

 

[khanar]

Yes

That s botulinum toxin ,right? In infants we can find constipation and it is often the first symptom to occur.Those infants appear floppy,lethargic and have a weak cry and poor muscle tone

Oh yeah, sure you are 100% right.

 

[khanar]

It's in Kaplan

botulinum toxin for sure.

atropin doesnt cause muscle weakness and fever. but a bacterial infection or viral could. plus the botulinum toxin notes is either in kaplan or FA. i remember reading it somewhere.

You must have read it in Kaplan
