No explanation was given. I'll need to do some homework for her, I guess. I get the feeling that it is just not necessary to make a switch to the IR.

I convinced her to return to XL until she has her surgery in a few months. If her physicians are unsure as to the efficacy of sustained release versions of Wellbutrin, but are convinced that it will do her no harm, then it is a no-brainer but to try as an experiment its use.

> I had a gastric by-pass in 2001...mine work with "malabsorbtion" ...mean that they just remove 2/3 of my stomach and they reduce my intestine to 1 meter long only, the other 5 meter is cut and don't work anymoreWow. That's quite a bit of pipe to be cut away. There are several different procedures available. For my friend, I am not sure how much small intestine will be unavailable for digestion. I am under the impression that most of it will remain intact. The duodenum is bypassed, but continues to secrete digestive enzymes that are routed back to the small intestine. In essence, a Y-pipe is constructed using some of the proximal small intestine. I have to find out more about it.
> I ask several times my surgeon about this, and about the fact that the new formulation XR of drugs seem to not work on me, since at one point of my life I Was on more than 300mg of Effexor-XR, without feeling anything...it was not normal... The only answer I get was that he don't know...He said that statically, I maybe absorb only 30% of the drug in my blood stream...normal digestion cycle is 12 hours, mine is 3-4 hours...and since I get this surgery, I find that all the drugs are less effective...so it"s affect probably also the regular version as well...since they by-pass the first part of the intestine, the one where the fat absorbtion in the intestine is made, and it's the part where normally a drug is absorbed...but some drugs seem to be well absorb...probably something to do with where a drug is absorb and metabolised...they are all different I think...but my psychiatrist told me that AD drugs are mostly absorb by the first part of the intestine and are fat-solube...mean that i'm not surprise I don't answer well to antidepressants drugs...

> Take my informations like you want, maybe i'm right or maybe i'm wrong, but a small stomach can't affect what happen in the intestine...If your friend take her Wellbutrin SR and swallow it, I see why it will not go into her intestine...so it will probably be absorb like usual in the intestine, since her surgery will not by-pass a big part of her intestine no???Thank you. You gave me much information to think about. I'll let you know what I come up with.
Be well.
