Diphenoxylate/atropine
What side effects?
Diarrhea med (opioid that slow down bowel motility and atropine is added for anticholinergic to help with the opiod effects f diphenoxylate) If they took too high a dose, then anti-cholinergic effects and a buzz..if a normal dose, drug is well tolerated
Dicyclomine (diarrhea med) is given for a disorder that can cause diarrhea. Example?
IBS
Does loperamide (diarrhea med) cross BBB, since it’s an opioid?
No…so no pain relief, euphoria, or addiction with it!
Diphenoxylate is an ____.
Atropine is an _____.
Why do we give atropine?
Diphenoxylate is an opioid and it can cause a buzz if you take too high of a dose of it. That’s why atropine is added, because it atropine is an anticholinergic, because if this drug is taken in high doses, the pt. will experience anti-cholinergic effects. AKA ones no one wants. So the buzz happens if you take too high a dose, but all these other effects happen too, and people don’t want those effects along with their “buzz”

Rare–this only happens if you are taking a REALLY high dose of the drug..normal dose would be about 8mg, but if you took 30mg, you may be at risk for prolonged QT–who takes that high of a dose? CHEMO PATIENTS!!
Why is it good that Ondansetron (anti-vomiting) comes in all sorts of forms?
Bc sometimes you can’t keep down anything and the PO route wouldn’t work
What is the major receptor Phenothiazine blocks?
Histamine
Side effects of Phenothiazine?
EPS (bc blocks dopamine), orthostatic hypotension (bc blocks alpha1)
