IIex paraguariensis Person drank that and came in with muscarinic blockage poisoning? Dry Skin, oral mucous membranes were dry, non reactive pupils , dever and bowel sounds were absent. Overstimulation of the muscarinic produces diahorea, frequent urination, miosis(contraction of eye) , increased GI motitility, increased lacrimation, sweating and salivation. So something in that yea from the IP cuased blockage of the Muscarinic receptors? Anticholinergic poisoning? The alkaloids present, atropine, scopolamine etc would of blocked the Muscarinic receptors? A good treatment for this would be ....muscarinic agonist?or maybe an anticholinesterase?
