Misc Is Caffeine A CYP1A2 Inducer Or Inhibitor?

[Thomas29]

Now I Need to Know If http://www.fda.gov/drugs/developmen...ources/druginteractionslabeling/ucm093664.htm this Website is Accurate. It Tells Me that Diphenhydramine is a CYP2D6 Inhibitor But that does Not Make Sense. I mean I know it Inhibits CYP3A4 but never heard of it inhibiting CYP2D6???

Methadone is Metabolized through CYP1A2 Partly and so I was Wondering what Effect Caffeine has on it and I know it wont be a NOTICEABLE FEELING OF A DIFFERENCE but like Grapefruit THERE IS A CLINICAL BLOOD PLASMA LEVEL Increase can Caffeine Inhibit CYP1A2 VERY VERY VERY WEAKLY I would Assume and have Read but i need an Experts Advice if it is True Or False.

I'm no chemist so I can't answer that but I had a friend who was arrested with heroin which was really good gear. When they analyzed it they said it had caffeine powder as one of the cuts in it. It was also 29.7% pure so of course it was good gear. My friend never cuts his gear but we've heard caffeine powder is quite popular as a cut these days.
