Alright, sorry for the spam, but this is so confusing, I have to write everything what's on my mind right now. When I thought about this, I came to the conclusion that both enzyme inducers and inhibitors have no effect on how fast the drug is being released of out the fat tissues. Correct me if I'm wrong. The rate of releasing the substance out of our fat tissues should always be the same, I guess. Out livers don't control it in any way, do they? When the inhibitor or inducer is administered, it affects the metabolism of drug molecules that will reach the liver with the blood, and does not affect the rate of release of the substance stored in other tissues or associated with proteins into the blood. So what happens if we take an inhibitor? The rate of the release of the drug from fat tissues doesn't change, but the liver is metabolising the drug in a slower rate, so there's constant release of the drug from fat tissues (always at the same rate), but the inhibitor makes our livers metabolize the drug slower, so there's more of the drug in our bloodstreams (easy, isn't it?). If we take an inducer, again, the rate in which the drug is being released from fat tissues is still the same, but the liver metabolizes the drug faster, so we're not influenced by it that much.
My conclusion is: taking an inducer could be the best thing to do. We won't eliminate the drug any faster, but this will allow us to experience less side effects, it seems logical to me. Maybe I was feeling so bad because I was constantly taking this propranolol which was causing a slower metabolism (but the drug was being removed always in a constant pace).
I may be wrong about this, so don't take it seriously, I would like more experienced users to express themselves about this matter.
