Correct guys.
However, why not give morphine, oxycodone, anelgesics etc????

I'm not exactly sure what u mean by increasing P of sphincter of oddi as english is not my first language but in the explanation they were saying that the anelgesics are used for moderate type of pain and wouldn't help the pt. much in this case.
As for the other narcotics, even though they could be used, Meperidine is chosen b/c it has antimuscarinic effects :arrow: doesn't cause vasospasms.
