I had the same eye-strain effect with Wellbutrin
SR.I'm not sure how the SR version works vs
the non-SR version. The reason the SR version was introduced was because the elimination time for the non-SR Wellbutrin was fast, thus requiring
multiple dosing during the day. The SR version was introduced to reduce the dosing schedule and
help to maintain a better steady state
level in the blood stream. In rare cases for
anorexics they found that the original Wellbutrin
may induce seizures due to spikes in the absorbtion in the blood. That was also a motive to design the SR version.I went to their website www.glaxowellcome.com,
but couldn't find the PDR for the non SR version.
Here is the PDR for the SR version:
http://www.glaxowellcome.com/pi/wellbusr.pdfMany times the clearance of a drug can be influenced by interactions with other medications that you may be taking? Are you taking anything else? This occurs because the amount of enzymes in the liver that metabolize the drugs can change.
I'm very curious as to what mechanism is used in
medications that are sustained released. I'll look into this and see if I can find out any more answers.-JohnX
