"Dec. 17, 2010 -- The FDA has rejected Brilinta, AstraZeneca's new blood thinner, because U.S. and Canadian patients did not benefit from the drug in a pivotal clinical trial.

Because clinical trials are conducted under widely varying conditions and durations of follow up, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.

Plavix has been evaluated for safety in more than 54,000 patients, including over 21,000 patients treated for 1 year or more. The clinically important adverse reactions observed in trials comparing Plavix plus aspirin to placebo plus aspirin and trials comparing Plavix alone to aspirin alone are discussed below.

The following adverse reactions have been identified during post-approval use of Plavix. Because these reactions are reported voluntarily from a population of an unknown size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.

Get emergency medical help if you have any of these signs of an allergic reaction: hives; difficulty breathing; swelling of your face, lips, tongue, or throat.

Plavix (clopidogrel bisulfate) is a thienopyridine class of drug that inhibits plaet aggregation and thus inhibits aspects of blood clotting. Plavix is available in the generic form termed clopidogrel bisulfate. This drug is used to treat patients with acute coronary syndrome, myocardial infarction (MI), peripheral vascular disease and some stroke (ischemic type) patients. The most common side effects are: increased bleeding, nose bleeds, headaches, and bruising.

Plavix is supplied as 75 and 300 mg tablets. For acute coronary syndrome with a non-ST elevation MI, the initial recommended dose is 300 mg, followed by a 75 mg dose per day; for ST elevation MIs, the initial and continuing dose is 75 mg per day. The recommended dose is 75 mg per day for patient with a history of MI, stroke, or peripheral vascular disease. Many doctors may choose to add an aspirin per day along with the Plavix dose in both non-ST elevation and ST elevation MIs as well as to stroke and peripheral vascular disease patients. Patients taking omeprazole have reduced Plavix efficacy due to CYP2C19 enzyme inhibition. (Some patients genetically also have this problem). Plavix should be used during pregnancy only if clearly needed. Most clinicians advise lactating females not to use Plavix, but nursing mothers should discuss the use of this drug with their OB-GYN physicians.

In CURE and CHARISMA, which compared Plavix plus aspirin to aspirin alone, there was no difference in the rate of adverse events (other than bleeding) between Plavix and placebo.

What is Prescribing information?

Table 2: Incidence of Bleeding Events in COMMIT (% patients) Type of bleeding Plavix (+ aspirin) (n=22961) Placebo (+ aspirin) (n=22891) p-value Major* noncerebral or cerebral bleeding** 0.6 0.5 0.59 Major noncerebral 0.4 0.3 0.48 Fatal 0.2 0.2 0.90 Hemorrhagic stroke 0.2 0.2 0.91 Fatal 0.2 0.2 0.81 Other noncerebral bleeding (non-major) 3.6 3.1 0.005 Any noncerebral bleeding 3.9 3.4 0.004 * Major bleeds were cerebral bleeds or non-cerebral bleeds thought to have caused death or that required transfusion. ** The relative rate of major noncerebral or cerebral bleeding was independent of age. Event rates for Plavix + aspirin by age were: < 60 years = 0.3%, ≥ 60 to < 70 years = 0.7%, ≥ 70 years = 0.8%. Event rates for placebo + aspirin by age were: < 60 years = 0.4%, ≥ 60 to < 70 years = 0.6%, ≥ 70 years = 0.7%

Common side effects may include itching.

In CAPRIE, which compared Plavix to aspirin, pruritus was more frequently reported in those taking Plavix. No other difference in the rate of adverse events (other than bleeding) was reported.

Report Problems to the Food and Drug Administration.

Stop using clopidogrel and call your doctor at once if you have any of these serious side effects:

In CAPRIE, gastrointestinal hemorrhage occurred at a rate of 2.0% in those taking Plavix vs. 2.7% in those taking aspirin; bleeding requiring hospitalization occurred in 0.7% and 1.1%, respectively. The incidence of intracranial hemorrhage was 0.4% for Plavix compared to 0.5% for aspirin.

In COMMIT, similar rates of major bleeding were observed in the Plavix and placebo groups, both of which also received aspirin (see Table 2).

In CURE, Plavix use with aspirin was associated with an increase in major bleeding (primarily gastrointestinal and at puncture sites) compared to placebo with aspirin (see Table 1). The incidence of intracranial hemorrhage (0.1%) and fatal bleeding (0.2%) were the same in both groups. Other bleeding events that were reported more frequently in the clopidogrel group were epistaxis, hematuria, and bruise.

Ninety-two percent (92%) of the patients in the CURE study received heparin or low molecular weight heparin (LMWH), and the rate of bleeding in these patients was similar to the overall results.

Our Plavix Side Effects Drug Center provides a comprehensive view of available drug information on the potential side effects when taking this medication.

Other bleeding events that were reported more frequently in the Plavix group were epistaxis and hematoma.
