All of the following about meperidine arc true except:
|A||Has shorter halflife than morphine|
|B||Greater spasmogenic action than morphine|
|D||Better oral bioavailability|

Pethidine (meperidine) is chemically an atropine congener, thereby may have spasmolytic effect at lower doses. Spasmodic action at higher doses is 1/3rd of morphine.
