In brief: A couple of hours

Amitiza (lubiprostone) can help one have a bowel movement in a couple of hours.
It can be taken at anytime, but probably works better if taken with a meal that includes water or beverages. That means one should not take Amitiza (lubiprostone) without knowing where the nearest bathroom is (for 1-4 hours after taking the medicine).
