netsavy006 Posted June 25, 2009 Share Posted June 25, 2009 I've never heard of Lamictal XR till now but I was browsing the GSK website and came across it. Here's the site to it's PI sheet which is all I can come by. It says it's initial appoval date was 1994. But like I said I've never heard of Lamictal XR. Anyone here ever heard of it or are on it: http://us.gsk.com/products/assets/us_lamictalxr.pdf Link to comment Share on other sites More sharing options...
quiet storm Posted June 25, 2009 Share Posted June 25, 2009 At first glance, smells like another classic patent extender ploy. Funny how this is just getting fda approval right around the time that regular lamictal went generic. You go GSK!!! The half life for regular lamictal is variable but if I remember right at the minimum the half life is about 24 hours. This should be more than enough time to cover anybody if they took it twice a day. Lamictal XR VS lamictal twice a day..........I bet its a wash.

Silver Posted June 25, 2009 Share Posted June 25, 2009 At first glance, smells like another classic patent extender ploy. Funny how this is just getting fda approval right around the time that regular lamictal went generic. You go GSK!!!Wild applause. Yep, I think you called that one. Major patent extender. What jerks. They must be really annoyed that they didn't get it approved, say, 20 months ago and get everyone used to writing it as an XR. Wait, now that I think about it - isn't this how they handled Paxil CR and Wellbutrin XL too? They're just a little slow on the uptake down there at GSK... eta: and I don't see much more clinical utility in it, with, I suppose, the exception being epileptic patients in later pregnancy, because the clearance increases so much. (These strike me as being people who would be taking their medication anyway.) I have to think about that and how the XR would work... But it's not like Topamax, which makes you too stupid to remember to take it. Lamictal makes a lot of us kind of ditzy, but not "lost in the corner" stupid. I guess it would be nice to have a once a day option, sure, great, fine. But, personally, I find an extra $150/month out of pocket to be an unacceptable side effect for a relatively low payoff that I can envision (with the exception above, maybe.) Even if I had a third party paying it. I'm still paying for it, one way or another. Still, nothing beats the sheer balls of Amrix: extended release Flexeril, when you can't possibly take Flexeril 2 to 3 times per day. I won't even tell you what it costs. Go look it up. Regular cyclobenzaprine is dirt-cheap. That wasn't even a patent extender. That was like a patent resurrection. Link to comment Share on other sites More sharing options...
