Considering the Bioavailability is 0.3% I doubt that trying to break it down before consumption would be of any benefit. Hacking ATC/ pGP is about the only way to "boost" it, but that gets dangerous and F's with the Dose-Response curve in unpredictable ways.
The generic brands break down in water very fast, like before you can swallow them fast if you swish a little.
Edit (can't edit my post right now):
What I meant to say was given that it's more lipophilic than hydrophilic sublingual might work (but this shouldn't help much if your main goal is to decrease gut motility)
