generally, you need ot be able to ingest and keep that pill in your GI tract for TWO HOURS for it to be absorbed. i can't think of a laxative that would user things through your guts in a time less than two hours. but if you have especially fast bowels, maybe consider switching to NuvaRing or OrthoEvra if you'll be taking laxatives for an extended period of time.
otherwise, have you considered fiber therapy before stimulant laxatives?
