Which of the following is not a clinical sign of atropine intoxication?

Atropine is an anticholinergic drug. It will decrease GI motility. PHARMACOLOGICAL ACTIONS of Atropine: Atropine  blocks  all  subtypes  of  muscarinic receptors. Tone and amplitude of contractions of stomach and intestine are reduced; the passage of chyme is slowed-constipation may occur, spasm may be relieved.  However,  peristalsis is only incompletely suppressed, because it is primarily regulated by local reflexes in the enteric plexus, and other neurotransmitters (5-HT,  enkephalin, etc.,) are involved. Enhanced motility due to injected cholinergic drugs is more completely antagonised than that due to vagal stimulation, because intramural neurons which are activated by vagus utilize a number of noncholinergic transmitters as well.
