Ten days later she presented to the Accident and Emergency department with significant painless fresh rectal bleeding associated with systemic symptoms of dizziness and nausea. Blood pressure was 90 50 mmHg and pulse 105 beats min. Resuscitation with oxygen and intravenous fluids was initiated. A full blood count taken on admission revealed haemoglobin of 7.7g dl. Significant fresh rectal bleeding persisted. Rigid sigmoidoscopy confirmed the source of bleeding as the site of previous haemorrhoidal banding. A silastic irrigation catheter was inserted into the anal canal and 50mls of water used to inflate the balloon. The patient was transfused 2 units of platelets, 2 units of fresh frozen plasma and 5 units of packed red cells. Bleeding stopped without operative intervention. Two days later a flexible sigmoidoscopy confirmed the source of bleeding, with no other pathology evident to a distance of 55cm from the anoderm. The patient made an uneventful recovery and was discharged home with advice to recommence clopidogrel in 7 days. CASE REPORT 2 A 56-year old woman was referred by her family doctor with a 3 month history of loose stools associated with intermittent bright red rectal bleeding. She had a history of.
Background: Clopidogrel, a potent inhibitor of platelet aggregation, is being commonly prescribed in the elderly population due to its benefits in patients with atherosclerotic diseases. It is currently unknown whether clopidogrel increases the risk of bleeding during invasive pulmonary procedures. Methods: Pigs of the Yorkshire species were randomized to one of the following two arms: clopidogrel 75 mg d ; alone; or clopidogrel plus aspirin 75 mg d and 325 mg d, respectively ; . The animals underwent flexible bronchoscopy with transbronchial lung biopsies under fluoroscopic guidance at baseline and after 1 week of daily oral intake of their assigned drugs. The main outcome of the study was the quantity of blood collected through the bronchoscope following transbronchial lung biopsy TBLB ; . Results: Sixteen animals were enrolled in the study, with 8 animals randomized to each arm. No statistically significant difference was found in the average quantity of blood resulting from transbronchial lung biopsies between procedures performed at baseline and those performed after animals received either clopidogrel mean [ SD] dose, 1.41 1.14 mL ; or clopidogrel plus aspirin mean dose, 1.75 1.28 mL; p 0.42 ; . Conclusions: Clopidogrel, with or without aspirin, does not increase bleeding complications after TBLB in healthy pigs. CHEST 2005; 127: 961964.

Bristol-Myers Squibb Sanofi-Synthelabo and Sanofi-Synthelabo Canada Inc. also instituted a prohibition action in the Federal Court of Canada against Apotex and the Minister of Health in response to a NOA directed against Canadian Patent 2, 334, 870 covering the form 2 polymorph of clopidogrel bisulfate. Apotex seeks approval of its ANDS before expiration of the `870 patent in 2019. Apotex alleges in its NOA that it does not infringe the `870 patent and that it is invalid. That action was discontinued. Sanofi-Aventis and Sanofi-Synthelabo Canada Inc. instituted a prohibition action in the Federal Court of Canada against Novopharm Limited Novopharm ; and the Minister of Health in response to a Notice of Allegation from Novopharm directed against Canadian Patent 1, 336, 777 covering clopidogrel bisulfate. Novopharm's NOA indicated that it had filed an ANDS for clopidogrel bisulfate tablets and that it sought approval a Notice of Compliance ; of that ANDS before the expiration of Canadian Patent 1, 336, 777, which expires August 12, 2012. Novopharm's NOA further alleged that the `777 patent was invalid. Novopharm has since withdrawn its NOA and agreed to be bound by the result in the Apotex proceeding. The prohibition action has therefore been discontinued. Sanofi-Aventis and Sanofi-Synthelabo Canada instituted a prohibition action in the Federal Court of Canada against Cobalt Pharmaceuticals Inc. and the Minister of Health in response to a Notice of Allegation from Cobalt directed against Canadian patents 1, 336, 777 and 2, 334, 870. Cobalt's NOA indicated that it has filed an ANDS for clopidogrel bisulfate tablets and that it sought a Notice of Compliance for that ANDS before the expiration of the `777 and `870 patents. Cobalt alleged that the `777 patent was invalid and that the `870 patent was invalid and not infringed. The case has been stayed pending the outcome of the Apotex appeal. Although the plaintiffs intend to vigorously pursue enforcement of their patent rights in Plavix, it is not possible at this time reasonably to assess the outcome of these lawsuits, or, if the Company were not to prevail in these lawsuits, or, if Apotex, which now has final approval of its aNDA in the U.S. were to enter the market with a generic product at risk, the timing of potential generic competition for Plavix. It also is not possible reasonably to estimate the impact of these lawsuits on the Company. However, loss of market exclusivity of Plavix and the subsequent development of generic competition would be material to the Company's sales of Plavix and results of operations and cash flows, and could be material to its financial condition and liquidity. See Note 8 "Income Taxes" for additional information. OTHER INTELLECTUAL PROPERTY LITIGATION Tequin. The Company and Kyorin Pharmaceuticals Co., Ltd. Kyorin ; commenced a patent infringement action on March 23, 2004, against Teva USA and Teva Industries in the United States District Court for the Southern District of New York, relating to the antibiotic gatifloxacin, for which Kyorin holds the composition of matter patent and which the Company sells as Tequin. Teva Industries has since been dismissed from the case. This action relates to Teva's filing of an aNDA for a generic version of gatifloxacin tablets with a certification that the composition of matter patent, which expires in December 2007 but which has been granted a patent term extension until December 2009, is invalid or not infringed. The filing of the suit places a stay on the approval of Teva's generic product until June 2007, unless there is a court decision adverse to the Company and Kyorin before that date. Trial in this matter has been scheduled to begin on May 1, 2006. Tequin injectable form ; . The Company and Kyorin commenced patent infringement actions on March 8, 2005, against Apotex Inc. and Apotex Corp., and against Sicor Pharmaceuticals, Inc., Sicor Inc., Sicor Pharmaceuticals Sales Inc., Teva Pharmaceuticals USA, Inc., and Teva Pharmaceutical Industries Ltd. in the United States District Court for the Southern District of New York, relating to injectable forms of the antibiotic gatifloxacin, for which Kyorin holds the composition of matter patent and which the Company sells as Tequin. The action related to Apotex's and Sicor's filing of aNDAs for generic versions of injectable gatifloxacin with p IV ; certifications that the composition of the matter patent, which expires December 2007 but which was granted a patent term extension until December 2009, is invalid. The filing of the lawsuits places stays on the approvals of both Apotex's and Sicor's generic products until July August 2007, unless there is a court decision adverse to the Company and Kyorin before that date. The Sicor case was consolidated with the above proceeding. In a stipulation approved by the U.S. District Court for the Southern District of New York on August 22, 2005, the parties agreed that the Apotex case will be stayed pending resolution of the Teva and Sicor cases, and that the parties will be bound by the outcome of the above litigation. Erbitux. On October 28, 2003, a complaint was filed by Yeda Research and Development Company Ltd. Yeda ; against ImClone and Aventis Pharmaceuticals, Inc. in the U.S. District Court for the Southern District of New York. This action alleges and seeks that three individuals associated with Yeda should also be named as co-inventors on U.S. Patent No. 6, 217, 866, which covers the therapeutic combination of any EGFR-specific monoclonal antibody and anti-neoplastic agents, such as chemotherapeutic agents, for use in the treatment of cancer. If Yeda's action were successful, Yeda could be in a position to practice, or to license others to practice, the invention. This could result in product competition for Erbitux that might not otherwise occur. The Company, which is not a party to this action, is unable to predict the outcome at this stage in the proceedings and

Health Canada has received 2 case reports of hepatitis suspected to be associated with clopidogrel. An 84-year-old woman was prescribed clopidogrel 75 mg d, orally ; as adjunctive therapy to Aspirin to prevent further transient ischemic attacks. No other medications were reported. Eight weeks after starting the clopidogrel therapy, she presented with clinical and laboratory signs of acute mixed hepatocellular-cholestatic hepatitis. Serologic testing ruled out infectious causes, and results for autoantibodies were negative. There was no history of alcohol abuse and no history of toxic exposure. Further workup showed no evidence of biliary tract disease, hemochromatosis or other metabolic liver disease. Liver biopsy confirmed the finding of hepatotoxicity, and clopidogrel was discontinued. Complete resolution of symptoms and biochemical profile occurred over several weeks.1 The other case report described a flare-up of hepatitis with elevated liver enzyme levels in a 76-year-old woman who had been receiving clopidogrel for about 11 months. However, insufficient information was reported regarding the patient's concomitant medications or medical conditions, which limits our analysis of the report.

Side effects of lopid dose
Coagulation disorders leading to either excessive bleeding or clotting are a concern of physicians who care for patients in the perioperative period. Though screening patients with a bleeding time, 1 partial thromboplastin time PTT ; 2 and prothrombin time PT ; 2 is frequently attempted, none of these tests, unfortunately, are sufficiently sensitive or specific to ensure problems will not develop. A routine blood count is useful for identifying patients with thrombocytopenia. When the platelet count is less than 50, 000 in patients who do not have immune mediated thrombocytopenia, the risk of bleeding is increased. The best test, however, for screening patients for a bleeding tendency remains an adequate history and physical examination. Patients who have severe liver or renal dysfunction, or a bone marrow disorder such as myleodysplasia, may have dysfunctional platelets and a tendency to bleed excessively even with a normal platelet count.3 It is well known that many drugs such as aspirin and ticlopidine cause platelet dysfunction and may contribute to excessive bleeding. When possible it is best to discontinue those medications at least a week prior to operation.
Interventional cardiologists say this risk is balanced by lower rates of restenosis--and they point out that longer use of antiplatelet therapy with ASA and clopidogrel Plavix ; may help address the problem. The latest stent thrombosis controversy heated up earlier this year with presentations at the American College of Cardiology annual meeting in Atlanta and the World Congress of Cardiology in Barcelona suggesting increased mortality see Late | page 85 and MI risks with the and mobic.

Toxicology Single dose toxicity of clopidogrel was evaluated in the rat, mouse and in the baboon. Repeated dose toxicity by the oral route was conducted in the mouse for up to 3 months, in the rat for up to 52 weeks and in the baboon for up to one year. After single oral administration to rats, mice and baboons, toxicity occurred only at very high doses. The target organs were mainly the gastrointestinal tract, the kidney and the lung. After intravenous administration to rats and mice, the main target organs were the kidney and the lung. The toxicity on the digestive tract was also shown in the repeated dose toxicity studies; in particular in rats and baboons treated orally with high doses from 400 mg kg day and upwards ; . The main toxicological finding at doses up to 400 mg kg day corresponded to increased liver weight associated with hypertrophy of the smooth endoplasmic reticulum in centrilobular hepatocytes corresponding to an effect on hepatic enzymes. The no-effect level, based on increased liver weight, were 27 mg kg day in rats and 65 mg kg day in baboons and correspond to an exposure of at least 7 times rats ; and more than 10 times baboons ; higher than that observed in humans at the recommended therapeutic dose A slight decrease in heart rate and a slight increase in QT interval were observed in rats and baboons at very high doses 1, 000 mg kg day in rats, and 400 mg kg day in baboons ; . However, there was no prolongation of QTc-interval. An in vitro electrophysiological study on rabbit Purkinje fibres was submitted with the responses to the consolidated list of questions. Although the results did not reveal a proarrhythmic potential, the highest concentration tested ~ 9.6 mg l ; was only three times the Cmax obtained in humans with the therapeutic dose ~ 2.7 mg l ; . This issue and its clinical relevance were further discussed during the hearing held on 24th February 1998. The CPMP considered that this issue had been satisfactorily addressed by the company and that it was resolved. The R-enantiomer of clopidogrel revealed a higher toxicity than the active compound, namely on the central nervous system. The impact of the toxicity of this impurity on the overall toxicological profile of clopidogrel formulation seems to be minor due to its low concentration in the test compound. Furthermore, there is no evidence of epimerisation in man. The reproduction toxicity studies in rats and rabbits did not reveal any teratogenic or faetotoxic potential for clopidogrel even at borderline maternally toxic doses. Male and female fertility, growth and development of the F1 offspring were not affected. High doses of clopidogrel induced a slight delay in the development of the offspring of lactating rats possibly due to the effect of the drug excreted in the lactating milk. The effect was reversible after weaning. In the light of these findings, and in the absence of significant experience in pregnant women, clopidogrel is contraindicated during breast-feeding and not recommended during pregnancy. A battery of in vitro studies and one in vivo mouse micronucleus assay did not reveal any mutagenic, genotoxic or clastogenic potential of clopidogrel. No immunogenic, antigenic, phototoxic or photoallergenic potential was observed. The carcinogenic potential of clopidogrel was investigated in two life-span studies in the rat and in the mouse. Both studies were negative. The company was requested to discuss the clinical relevance of the increased incidence of thyroid cysts observed in the rat carcinogenicity study taking into account the high level of sustained radioactivity observed in the thyroid gland in the tissue distribution studies. The company stated that developmental cysts are embryonic vestiges and do not represent lesions with neoplastic potential. This explanation was considered satisfactory. 4.

Illness of acute coronary syndrome ACS ; patients in a managed care setting. It is important to further characterize these patients as revascularization strategies during or after the index event become more common. The goal of this study was to examine demographic, health characteristics, and total health care utilization in ACS patients undergoing revascularization during the first year of follow-up care. METHODS: A retrospective, claims analysis was conducted for the period July 1, 1999-June 30, Patients were included with new-onset ACS, defined as an emergency room visit or hospitalization with an ICD-9 code for unstable angina or acute myocardial infarction AMI ; , without an ACS claim in the previous 6 months. Patients were followed up to 12 months to identify total medical and pharmacy costs, revascularization procedures, and medication use. RESULTS: A total of 13, 731 ACS patients were identified and 6, 929 50.4% ; underwent revascularization, 69% of these during the initial ACS hospitalization period. Mean age was 55 years and 72.9% were male. Revascularization was percutaneous coro n a ry intervention PCI ; in 5, 002 and bypass surgery in 1, 927. The index ACS event was AMI in 48.9% of patients, while 13.5% had both AMI and unstable angina. Common comorbidities were: lipid disorders 86.3% ; , hypertension 77.1% ; , cardiac arrhythmias 38.4% ; , fibrositis myalgia arthralgia 34.1% ; , diabetes 30.5% ; . A total of 3, 553 rehospitalizations occurred during follow-up. Total cost health plan plus patient ; was $210.7 million $30, 402 per patient ; . The majority of costs were medical $197.9 million ; rather than pharmacy $12.8 million ; . Hospitalization costs were $161.7 million $23, 331 per patient ; . During follow-up, 75.8% received a beta-blocker, 78.9% a cholesterol-lowering medication statin 75.5% ; , 46.3% an ACE inhibitor, 63.5% of all patients received clopidogrel therapy 84.8% of PCI patients ; . Mean days of clopidogrel therapy were 83.5. CONCLUSIONS: Similar to the Medicare population, these data indicate that the typically younger ACS patients in U.S. managed care plans incur substantial costs in the one-year following initial presentation. Revascularization is a frequent therapeutic strategy, but opportunities remain to improve medication therapy in these patients and

Among the specific therapeutic effects claimed for atypical drugs is their ability to alleviate mood symptoms associated with the psychotic disorder. Although this has not been definitively proved, preliminary results indicate that mood symptoms may selectively abate with atypical drugs. This evidence suggests that patients with schizoaffective disorder, residual mood symptoms e.g., postpsychotic depression ; , a history of, or current, suicidal behavior, and violent behavior may benefit most from treatment with an atypical drug as compared to a conventional antipsychotic agent.

As shown in the table, PLAVIX clopidogrel bisulfate ; was associated with a lower incidence of outcome events of every kind. The overall risk reduction 9.8% vs. 10.6% ; was 8.7%, P 0.045. Similar results were obtained when all-cause mortality and all-cause strokes were counted instead of vascular mortality and ischemic strokes risk reduction 6.9% ; . In patients who survived an on-study stroke or myocardial infarction, the incidence of subsequent events was again lower in the PLAVIX group. The curves showing the overall event rate are shown in Figure 1. The event curves separated early and continued to diverge over the 3-year follow-up period.
Abstract 222910: "Effects of antisecretory drugs and nitrates on the risk of ulcer bleeding associated with NSAIDs and anti-platelet agents" This is a study from Spain by Dr. Lanas and colleagues; another group of very experienced investigators with lots of publications on GI bleeding. Let me give you a little bit of background on this particular abstract because not everyone may be familiar with the effect of nitrates on GI bleeding. It has been known experimentally that nitric oxide increases blood flow in the gastric mucosa. At least in rats, administration of drugs that release nitric oxide, such as transdermal nitroglycerin, accelerates the healing of ulcers. In fact, there are drugs that are under development including NSAIDs and aspirin and other drugs that release nitric oxide with the thinking that they may be less damaging to the gastric mucosa. Preliminary studies have shown that aspirin derivatives that release nitric oxide may induce less damage in the GI mucosa. On the other hand, nitrovasodilators inhibit platelet aggregation which may contribute to GI bleeding. Because of this information, known in the basic science literature, this group from Spain did a preliminary study followed by a larger study that was published in the New England Journal of Medicine in September, 2000 entitled "Nitrovasodilators, low dose aspirin or other non-steroidal antiinflammatory drugs and the risk of upper GI bleeding." The authors are the same group. They found that use of non-steroidal anti-inflammatory drugs other than low-dose aspirin were associated with an increased risk of bleeding from peptic ulcers. The important conclusion, however, was that use of nitrovasodilators was associated with a decreased risk of bleeding odds ratio was 0.6, 95% CI of 0.4-0.9, similar to antisecretory therapy ; . Their thought was that nitrates might be protective. Building on that particular study, they did another study which is being presented at this meeting. This abstract is a case-controlled study with prospective data collection. Patients were seen at 40 general hospitals in Spain which included 2, 077 consecutive patients admitted with upper GI bleeding confirmed by endoscopy. They had a control group in a 2: ratio so the control patients were 5, 532 patients who were matched by age, hospital, and month of interview. The controls were not hospitalized for ulcer bleeding, NSAID, or aspirin-related diagnosis. Their primary endpoint was risk of being admitted with upper GI bleeding according to PPI, H2 receptor antagonist and nitrate use. They did not do any intervention. Of the 2, 077 overall patients, they found that PPI, H2 blockers and nitrates all reduced risk of being admitted with GI bleeding. The risk reduction ranges from 0.33 to 0.65 to 0.52 for nitrates. When they looked at the group of patients who took aspirin and NSAIDs only, patients who had PPI and H2 blockers were less likely to be admitted with bleeding. If they looked at patients who took low dose aspirin, PPIs and H2's were protective but nitrates were not. They also state that there was no significant difference among the three most common NSAIDs used in Spain diclofenac, ibuprofen, and Naprosyn ; . All had the same bleed risk. In terms of clopidogrel Plavix ; , only PPI was effective with a relative reduction of 0.19. In patients on anticoagulants, none of these drugs were protective. Their conclusion was people with nitrates, H2 blockers, or PPIs are associated with reduction of risk of developing upper GI bleeding when taking NSAIDs or aspirin or a subset taking aspirin only at regular doses. Only PPI was associated with a marked and consistent risk reduction among patients receiving all types of agents including non-aspirin antiplatelet agents, which if reproduced is relatively new. In other words, PPIs are the best. Again, something I think all of us knew in this room. Lastly, they concluded that nothing was effective for patients who are on anticoagulation. I had a few comments about the abstract. We're looking at only the abstract, so it is hard to know what was actually done since they only have a small amount of room to describe the study. Because this was a large study collected from a number of hospitals, the definition of medication use was not exactly specified.

Complications Those with GERD are at risk for complications including esophagitis, stricture, or Barrett's esophagus, all of which result from the damage to the esophageal mucosa, and the changes caused by subsequent repair and fibrosis. Irritation of the esophagus, if left untreated, can lead to bleeding, ulcers, and chronic scarring. This scarring can cause strictures, which may interfere with the ability to swallow. Barrett's esophagus is a condition involving cellular changes in the esophagus. It is considered a potentially precancerous disease. The number of people who develop Barrett's esophagus is relatively small, however, 25% of patients with Barrett's esophagus eventually develop adenocarcinoma of the esophagus. Once diagnosed with Barrett's esophagus, follow up endoscopic screening for cancerous cells every two to three years is advised. Esophageal rupture can occur in patients who have been vomiting and in debilitated elderly people with chronic lung disease. A tear of the weakened mucosa at the junction of the linings of the esophagus and stomach is called a Mallory-Weiss tear, and most often occurs in alcoholic men. This serious injury occurs after an episode of vomiting, causes pain below the lower sternum, and can cause severe bleeding. Diagnosis is confirmed via endoscopy. Most tears stop bleeding spontaneously and heal without surgical intervention. Occasionally, however, medical intervention with vasopressin or suturing of the tear is necessary.

Plavix Iscover Plavix clopidogrel ; , a platelet adenosine diphosphate ADP ; receptor antagonist with a rapid onset of action that selectively inhibits platelet aggregation induced by ADP, is indicated for long-term prevention of atherothrombotic events in patients with a history of recent myocardial infarction, recent ischemic stroke or established peripheral arterial disease. Plavix is currently the only drug indicated for the secondary prevention of atherothrombosis regardless of the location of the arteries initially affected heart, brain, lower limbs ; . This indication is supported by the results of the landmark CAPRIE trial, including almost 20, 000 patients. CAPRIE demonstrated the superior efficacy of Plavix over acetylsalicylic acid ASA, the active ingredient in Aspirin ; , with a comparable safety profile. Plavix was launched in 1998, and is now marketed in over 80 countries, including the United States, through our alliance with Bristol Myers Squibb BMS ; . In Japan a New Drug Application NDA ; for marketing authorization was approved in January 2006 and launch took place in May 2006. Sales of Plavix in Japan are consolidated by sanofi-aventis and are outside the scope of our alliance with BMS. Since 2002, Plavix has also been indicated for the treatment of non ST segment elevation Acute Coronary Syndrome ACS; non-Q-wave myocardial infarction and unstable angina ; in combination with ASA following the very significant results of the CURE trial. This indication was rapidly incorporated into the guidelines of the American Heart Association, the American College of Cardiology and the European Society of Cardiology. The CURE trial demonstrated that Plavix provided significant early- and long-term benefits in patients with Non ST segment elevation Acute Coronary Syndrome ACS ; . Plavix reduced the relative risk of atherothrombotic events myocardial infarction, stroke and death from a cardiovascular cause ; by 20% when added to standard therapy including ASA, with a 1% increase in the rate of major bleeding. With more than 12, 000 patients enrolled, CURE is the largest clinical trial ever conducted in patients presenting unstable angina or non-Q-wave myocardial infarction. Based on its broad clinical evidence base in this population, Plavix has gained the highest grade of recommendation in recent guidelines issued by medical societies for the management of ACS and Percutaneous Coronary Intervention PCI ; . Also in the cardiology field, the results of the CLARITY and COMMIT clinical trials have led to the approval of a new indication in ST-segment elevation ACS Q-wave myocardial infarction ; . This approval was granted by the FDA in August 2006 and by the EMEA in September 2006. The CLARITY trial, which enrolled nearly 3, 500 patients, demonstrated that Plavix, added to standard therapy including fibrinolytics and ASA, reduced the odds of acute myocardial infarction patients having another occluded artery, a second heart attack or dying after one week of hospitalization, as well as the odds of clinical events such as cardiovascular death, recurrent myocardial infarction and certain recurrent ischemias at 30 days. The COMMIT trial, which enrolled nearly 46, 000 patients, demonstrated that Plavix, added to standard therapy including ASA, reduced mortality in acute myocardial infarction patients at day 28 in an in-hospital setting. The indications resulting from the results of the CURE, CLARITY and COMMIT trials make Plavix a cornerstone therapy in management of ACS patients. Other studies have also contributed to further explore the role of clopidogrel in various patients' profiles mostly atherothrombotic patients ; : The results of the CREDO clinical trial, announced in November 2002, confirmed the therapeutic value of Plavix in the early- and long-term prevention of atherothrombotic events in patients having undergone coronary angioplasty, either with or without stenting. The CREDO trial, conducted in over 2, 000 patients, demonstrated the efficacy of Plavix, which reduces the relative risk of atherothrombotic events by 27% after one year; The MATCH trial results released in March 2004 showed that ASA did not provide additional clinical value benefit risk ratio ; in specific patients who have recently experienced a stroke or transient ischemic attack when added to Plavix and other standard therapies. 19 and

The clopidogrel versus aspirin in patients at risk of ischemic events caprie ; study17 followed 19, 185 patients with recent myocardial infarction, stroke, or symptomatic pad who were randomized to either clopidogrel 75 mg daily or aspirin 325 mg daily.
Higher doses In recent clinical studies of patients undergoing stenting, a 600 mg clopidogrel loading dose was associated with a higher level of platelet inhibition, lower mean post-treatment reactivity to ADP, and a lower incidence of nonresponsiveness when compared to a 300 mg dose [25, 28, 37, 60]. Moreover, a 600 mg clopidogrel loading dose was associated with a narrower response profile [25]. Kastrati et al found that patients achieved additional platelet inhibition when a 75 mg day clopidogrel maintenance dose was followed by an additional 600 mg loading dose [61]. In the CLEAR PLATELETS Study a 600 mg loading dose was associated with a superior pharmacodynamic antiplatelet profile compared to a 300 mg clopidogrel loading dose [37, 38]. In the recent ISARCHOICE Intracoronary Stenting and Antithrombotic Regimen: Choice Between 3 High Oral doses for Immediate Clopidogrel Effect ; Study, there was a ceiling effect in unchanged clopidogrel and clopidogrel metabolite levels and platelet inhibition with the 600 mg loading dose, and no significant additional effect was seen with the 900 mg loading dose. Based on the pharmacokinetic profile of the free drug and metabolites the investigators concluded that intestinal absorption was the major factor explaining response variability [62]. Thus, higher loading doses may be considered for selected patients exhibiting high platelet reactivity to ADP However, the superiority of a high dose regimen . in reducing ischemic events and the associated risk profile compared to a standard dose has yet to be established in large scale clinical trials. Despite these limitations, the current ACC AHA guidelines for PCI provide a Class IIa recommendation that "a regimen of greater than 300 mg is reasonable to achieve higher levels of antiplatelet activity more rapidly". Finally, the ACC AHA Guidelines provide a Class IIb recommendation that "in patients in whom subacute thrombosis may be catastrophic or lethal. platelet aggregation studies may be considered and the dose of clopidogrel increased to 150 mg per day if less than 50% inhibition of platelet aggregation is demonstrated" [63]. The latter guidelines however, do not specify the methodology that should be used to assess inhibition. Moreover, there are very limited clinical.
