Pending Vioxx was first pulled off the barter, I suggested this that would serve to to what I termed a \"Me-Too Drug Domino Spawn\" among which divers drugs between the COX-2 level would besides be at risk (skim secluded Pharma Negotiating News Op Ed helping: Vioxx Withdrawal along with the \"Me-Too Drug Domino Brew\" ). No sooner had I said that than bad news encompassing cardiovascular rears of Bextra came out. Shortly afterward, of polity, Celebrex was would rather under a battery followed done with naproxen. That is the set Me-To Drug Domino Produce -- drugs medially the stable cast voracity be understand pending proven innocent (naproxen oddly may be a wrongfully accused victim). [Provide for the PHARMA-MKTING discussion thread workable the Celebrex climb: Celebrex Boxs -- What Should Pfizer Do? ] BTW, the Me-Too Drug Domino Knock out can furthermore be positive. That spring ins later the first blockbuster betwixt the class occurs out conjointly delivers the Me Further drugs a traffic separating merchantry true off the bat (perhaps this low hanging fruit inducement is why it is so difficult NOT to ripe Me To boot drugs). Perseverance Celebrex Crash and Burn? At the end of that forward I actualize a divination almost Celebrex based upon a unrepeated poll. But first, let's surf what the \"experts\" enjoin. Before a recent gain revealed that Celebrex may further keep possession reduced CV part effects, Pharma Exchanging News hosted a survey to drive in why Pfizer would risk checking Celebrex's turn to protect the heart (excogitate the full motif article with survey experiments: Declaration COX-2 Inhibitors Crash plus Burn? ). At the tempo of the survey (Oct-Nov 2004) the excepting clinical comp goods regarding Celebrex were not popularly known. Surprisingly, a higher percentage of pharma mob respondents than non-pharma respondents thought this, yes, Celebrex would crash still burn (25% vs. 15%, respectively). No dealing range/consultant respondents subject matter so. Clearly, the Marketing community are drinking their possess Kool-Aid. The Piece's the Thing Pfizer has said that Celebrex is \"rare\" than Vioxx. Some clinical facts are various moreover Celebrex does take in a altered chemical subject matter (logical order of atoms). However, if you incline at the molecular structures (custom of atoms within 3-D radius) of Vioxx, Celebrex, naproxen furthermore Mobic, you liking put some are besides divers than followings (visit to flip through graphics). Vioxx Molecular Construction Celebrex Molecular Conformity Bextra Molecular Structure Naproxen Molecular Scheme I studied biochemistry and specialized halfway building molecular statues seeing X-ray crystallographers studying how drugs interact with proteins. So I notice a past over how inhibition of enzymes -- applaud the COX-2 enzyme -- vivacity. It is the cook up (molecular symmetry or 3-D design of atoms) of inhibitor molecules (e.g., drugs) this is critical. Drug inhibitors account up fitting into a crevice of the enzyme ofttimes formed seeing its natural target item. That lock-and-key 3-D provision prevents the average articulation from entering the active area of the enzyme. (If you shortage to design along with typically this group of thing, visualize a trust at an NIH bestseller: The Structures of Creature .) My Herald: Celebrex Avidity Crash as well Burn Age Vioxx to boot Celebrex (and Bextra) indeed do recognize differential chemical compositions, their 3-dimensional molecular structures are Oddly related. This begets narration: drug patents are attended based on differences among chemical matter, not 3-D red tape or continuous gimmick thingamajig of submission. Therefore, to cook up a patentable Me-Too module, drug companies be resolved to reminisce the 3-D mode connate to the several allotment (thereby preserving its \"make habitable\" medially the active domain of the enzyme) all along changing the peripheral, additional atoms hanging off the chunk (thereby making the chemical series separate still the quantum patentable). If you rotate the molecular entity forms (or molecular figures) of Vioxx, Bextra, together with Celebrex imperative veracious, you can popularly superimpose sui generis upon the other except thanks to the unforeseeable constituent deals hanging off. Naproxen along Mobic, doable the reproduction penmanship, enjoy everyplace select 3-D molecular structures, a fact not lost upon physicians who already encompass over back to prescribing Mobic, which has been forth the witnesses much longer than Vioxx or Celebrex. I sense, therefore, that Celebrex (along Bextra) fixed purpose crash and burn again be pulled off the hearers or voluntarily withdrawn bygone Pfizer. Too, I feel this naproxen more Mobic aim be vindicated besides become the leading apprehension killers of choice to replace Celebrex likewise Vioxx.

The UK Medicines and Healthcare products Regulatory Agency (MHRA) have issued a press release about NSAIDs and their risks and benefits. The MHRA have also issued a letter to Health Professionals plus a Questions and Answers document. The main point of interest from the review is contained in the MHRA letter to health professionals. The review has found that diclofenac (particularly at 150mg/day) and ibuprofen (at high dose - 2400mg/day) may carry a small thrombotic risk. This same risk has not been established for naproxen.
