I believe that part of the reason that Viagra works in relaxing smooth muscle is its effect on Nitric Oxide which is a real hot compound right now - it has been implicated in all sorts of things and there are even web sites that are dedicated to the study of NO, as they call it.
I would suggest that Viagra would not be practical as a preventative for all sorts of reasons and that it would definitely not be an effective as an abortive since it dilates rather than constricts.
I do not profess to have any real insight to any of this but I do know that among a lot of other claims regarding Nitric Oxide, it is considered to be a key component of hypertension and other vascular stuff - so maybe you are on to something after all.
