I am sure this is nothing new to many of us, but nevertheless interesting and confirmational. I found an article from the Wall Street Journal Online, June 6 2002, Prilosec's Maker Switches Users To Nexium, Thwarting Generics, explaining AstraZeneca's situation surrounding the loss of their Prilosec patent. (Do a search on the underlined title in Google and the first hit should be it, it is a worthwhile read)
Some Key Points I found interesting (somewhat paraphrasing):
*Astra-Merck expected to find few unhappy Prilosec users, but surveys showed only half of those who used the drug were entirely pain-free and satisfied.
---From Reading this forum, i suspect this is true for all the drugs, Aciphex, Protonix, Preacid etc...So all you who still have pain with the meRAB, the drug companies know this and it apparently is up to you to do what works for you, whatever that might be
*Nexium is one-half of the Prilosec molecule -- an isomer of it. Sometimes the drug that results has fewer side effects or is more effective. Often it works just the same.
---Astra was looking for a fast cheap way to get a drug out for sale that they had complete control.
*Astra found that this half-of-Prilosec molecule seemed to get into the blooRABtream more efficiently than the whole Prilosec. While executives doubted it would work any better against heartburn, they thought it might be better against something called erosive esophagitis, where burped-up stomach acid injures the esophagus.
---Astra was looking hard for a reason to state Nexium would be better then Prilosec. They doubled the dose of Nexium over Prilosec to get approval to treat erosive esophagitis.
*Two studies showed there were no improvements between the larger dose of 40 mg Nexium vs the smaller dose of 20mg Prilosec until finally a two more studies showed Nexium eked out a slight advantage after 8 weeks, 90% healing rate vs 87%.
---One wonders what testing attributes did Astra massage to get the last 2 studies to get a slight victory, or what would the results be if they compared Nexium to an equal dose of Prilosec (40mg).
*two studies states the Prilosec and Nexium are equal in effectiveness for erosive esophagitis.
*Astra's lawyers persuaded patent clerks in Europe and the U.S. that its scientists had made a novel discovery when they came up with this triple-layering. A British judge later invalidated this patent because of "obviousness." But in the U.S., the trial on the patent's validity has been grinding on since Deceraber in New York. Every day the trial continues, AstraZeneca collects another $10 million in Prilosec sales, on average. Equally important, it gains more precious time to switch Prilosec users over to Nexium.
---It's all about money!
*Kaiser Permanente, the largest managed-care group, is nonetheless discouraging its physicians from prescribing Nexium. The reason, says David Campen, a Kaiser physician and pharmacy executive: "Nexium clearly is no value-added drug.
Bottom line, if you are short on money, just use the generic omeprazole or Prilosec OTC. Clearly Astra's invention of Nexium used a common way to re-patent a drug for sale. If Prilosec was still under patent, you can bet they would be touting Prilosec as the best drug available. For the drug companies suits, its all about the money, the patents and control, not the patients health (although the scientist working for the companies it is probably more about the cure).
