硫酸氢氯吡格雷片的功效与作用
硫酸氢氯吡格雷片是一种常用的抗血小板药物,它主要的功效和作用包括以下几个方面。
第一,抗血小板聚集作用。
使用硫酸氢氯吡格雷片可以抑制血小板的聚集,减少血小板在血管内壁上的黏附,避免血栓的形成。
这是硫酸氢氯吡格雷片用于预防和治疗心脑血管疾病的主要作用。
血小板聚集是心脑血管疾病的重要机制之一,因此使用硫酸氢氯吡格雷片可以有效预防和治疗心脑血管疾病的发生和进展。
第二,预防心脏病发作。
硫酸氢氯吡格雷片可用于预防冠心病、心肌梗死和心绞痛等心脏疾病的发作。
冠心病是一种常见的心脏疾病,其主要病因是冠状动脉发生狭窄或闭塞,导致心肌缺血。
硫酸氢氯吡格雷片可以有效地抑制血小板聚集,防止血栓形成,减少心肌缺血和心脏病发作的风险。
第三,预防血栓栓塞。
硫酸氢氯吡格雷片还可用于预防血栓栓塞疾病,如深静脉血栓形成和肺栓塞。
血栓栓塞是一种严重的血管疾病,它会导致血管堵塞,影响血液循环和器官功能。
硫酸氢氯吡格雷片可以阻止血小板聚集和血栓形成,减少血管阻塞的发生,预防血栓栓塞的发生。
总的来说,硫酸氢氯吡格雷片是一种常用的抗血小板药物,其功效与作用主要包括抗血小板聚集、预防心脏病发作和预防血栓栓塞。
它可以有效预防和治疗心脑血管疾病的发生和进展,降低心脏病和血管疾病的风险。
然而,在使用硫酸氢氯吡格雷
片时,应注意遵医嘱使用,避免因个体差异和药物相互作用等原因造成不良反应。

硫酸氢氯吡格雷片的作用机理硫酸氢氯吡格雷片,听起来像个科学怪人,其实它的作用机理就像是一个温柔的小帮手,默默地在你体内工作,让你保持健康。
我们平时说到“心脏”,很多人可能想到的就是那些心跳加速的浪漫时刻,或者是那种紧张的瞬间。
但你知道吗?心脏可不只是个情感的载体,更是我们身体里最重要的“泵”。
它得好好工作,才能让血液在我们的血管里畅通无阻。
硫酸氢氯吡格雷片的作用,就是为了确保这条血管路畅通无阻,不被“堵车”。
这药的名字听起来复杂,其实它是通过抑制血小板的聚集来发挥作用的。
想象一下,血小板就像是赶着去参加派对的小伙伴,聚在一起形成“血栓”。
这就像在拥挤的商场里,有些人过于热情,结果把路堵得严严实实。
硫酸氢氯吡格雷片就像是个和事佬,告诉这些小伙伴:“哎,别这么急!我们得分开点,不然大家都进不了门。
”这样一来,血液流动就顺畅多了,心脏也能舒心地工作。
说到这个药,有些人可能会问,它是怎么和身体里的这些小血小板“对话”的呢?其实很简单。
这药会进入你的血液,然后跟那些血小板上的某些受体结合,就像是一把钥匙打开了一扇门。
等门打开了,血小板就失去了聚集的能力,咱们的血液就不会出现堵塞的问题了。
你能想象吗?就像是派对上的DJ调低了音量,大家心情轻松,纷纷开始享受舞池的乐趣。
没了聚集,咱们的心脏也不会因为“人满为患”而苦恼。
有趣的是,这种药的效果并不是立竿见影的哦。
要是你觉得自己吃了药后马上就能感觉到心脏的变化,那就有点不现实了。
它就像一位温柔的园丁,慢慢地培育着你的身体,帮助你打理健康的花园。
要经过一段时间,才能看到效果。
你得有耐心,这就像养花,不能一时心急就想看到鲜花盛开。
时间长了,你会发现自己的身体变得越来越好,心脏也在稳稳地跳动。
任何药物都有它的优缺点。
硫酸氢氯吡格雷片也不例外。
虽然它在抑制血小板聚集方面非常有效,但有些人可能会出现出血的风险。
这就像一把双刃剑,使用得当可以保驾护航,但一旦操控失误,可能就会带来麻烦。
波立维功效有什么
波立维是一种处方药,在日常的疾病治疗当中有着巨大的功效,也是一种促进血小板集聚抑制的药,一般在临床上用到的比较多,不过这种药物一般人很少听说,只是因为我们接触到医学的比较少,一般的医生对这种药都特别熟悉,那么,波立维功效有什么?对于这样的问题,我们下面一起了解一下。
波立维是什么呢?
波立维通用名为硫酸氢氯吡格雷片,英文名为Plavix,氯
吡格雷是一种血小板聚集抑制剂,属于ADP受体拮抗剂,能选择性地抑制二磷酶腺苷(ADP)与它的血小板受体的结合及继发的ADP介导的糖蛋白GPⅡb/Ⅲa复合物的活化,因此可抑制血小板聚集。
波立维有哪些功效和作用呢?
硫酸氯吡格雷是一种新型高效的抗血小板药物,临床上应用于治疗动脉粥状硬化疾病、急性冠脉综合症以及血栓性并发症等。
因此,波立维适用于有过近期发作的中风、心肌梗塞和确诊外周动脉硬化的患者,波立维(氯吡格雷)可减少动脉粥样硬化性事件
的发生(如心肌梗塞,中风和血管性死亡)。
与其他抗血小板药物相比,硫酸氯吡格雷具有疗效强、费用低、副作用小等优点。
通过上述的介绍,我们知道了波立维功效有什么,不过需要注意的就是对于女性来说,怀孕期间、哺乳期间是不能使用的,另外也没有儿童使用的情况,在平时服用的时候我们不要自行盲目使用,一定要在医生的指导下服用。
硫酸氢氯吡格雷片药品介绍【药品名称】通用名:硫酸氢氯吡格雷片商品名:波立维英文名:ClopidogrelHydrogenShlfateTablets英文商品名:PLAVIX汉语拼音:Liusuanqinglubigeleipian本品主要成份及其化学名称:硫酸氢氯吡格雷【性状】口服剂波立维为粉红色,圆形,双凸,刻痕薄膜包衣片,一面刻有75,另一面刻有1171,含97.875mg的硫酸氢氯吡格雷,相当于75mg的氯吡格雷碱。
【药理毒理】药效学特性:氯吡格雷是一种血小板聚集抑制剂。
ATC分类为:BO1AC/04。
氯吡格雷选择性也抑制二磷酸腺苷(ADP)与它的血小板受体的结合及继发的ADP介导的糖蛋白GPlllb/llla复合物的活化,因此可抑制血小板聚集,氯吡格雷必须经生物转化才能抑制血小板的聚集,但是还没有分离出产生这种作用的活性代谢产物。
除ADP外,氯吡格雷还能通过阻断由释放的ADP引起的血小板活化的扩增,抑制其它激动剂诱导的血小板聚集。
氯吡格雷不能抑制磷酸二酯酶的活性。
氯吡格雷通过不可逆地修饰血小板ADP受体起作用。
暴露于氯吡格雷的血小板的寿命受到影响。
而血小板正常功能的恢复速率同血小板的更新有关。
从第一天起,每天重复给氯吡格雷75mg,抑制ADP诱导血小板聚集,抑制作用在3-7天达到稳态。
在稳态,每天服用氯吡格雷75mg平均抑制水平维持中40%-60%,在治疗中止后一般约在5天内血小板聚集和出血时间逐渐回到基线。
氯吡格雷的临床疗效来自于CAPRIE临床试验。
该试验的入组病人有19,185个,为多个中心,多国家,随机双盲比较氯吡格雷(75mg/天)和阿司匹林(325mg/天)作用的平行临床研究。
随机入选的病人为:1)有近期心肌梗死史(35天内)2)近期缺血性中风史(7天-6个月内),至少近一周内仍有继发神经系统症状。
3)确诊外周动脉疾病(PAD)病人接受随机治疗1-3年,在心肌梗死组中,大多数患者在急性心肌梗死后的初期服用阿司匹林。

Plavix at recommended doses forms less of that metabolite and has a smaller effect on platelet function in patients who are CYP2C19 poor metabolizers. Poor metabolizers with acute coronary syndrome or undergoing percutaneous coronary intervention treated with Plavix at recommended doses exhibit higher cardiovascular event rates than do patients with normal CYP2C19 function. Tests are available to identify a patient's CYP2C19 genotype; these tests can be used as an aid in determining therapeutic strategy [see Clinical Pharmacology (12.5)]. Consider alternative treatment or treatment strategies in patients identified as CYP2C19 poor metabolizers [see Dosage and Administration (2.3)].1 INDICATIONS AND USAGE1.1 Acute Coronary Syndrome (ACS)• For patients with non-ST-segment elevation ACS [unstable angina (UA)/non-ST-elevation myocardial infarction (NSTEMI)], including patients who are to be managed medically and those who are to be managed with coronary revascularization, Plavix has been shown todecrease the rate of a combined endpoint of cardiovascular death, myocardial infarction (MI), or stroke as well as the rate of a combined endpoint of cardiovascular death, MI, stroke, or refractory ischemia.• For patients with ST-elevation myocardial infarction (STEMI), Plavix has been shown to reduce the rate of death from any cause and the rate of a combined endpoint of death,re-infarction, or stroke. The benefit for patients who undergo primary percutaneous coronary intervention is unknown.The optimal duration of Plavix therapy in ACS is unknown.1.2 Recent MI, Recent Stroke, or Established Peripheral Arterial DiseaseFor patients with a history of recent myocardial infarction (MI), recent stroke, or established peripheral arterial disease, Plavix has been shown to reduce the rate of a combined endpoint of new ischemic stroke (fatal or not), new MI (fatal or not), and other vascular death.2 DOSAGE AND ADMINISTRATION2.1 Acute Coronary SyndromePlavix can be administered with or without food [see Clinical Pharmacology (12.3)].• For patients with non-ST-elevation ACS (UA/NSTEMI), initiate Plavix with a single 300 mg oral loading dose and then continue at 75 mg once daily. Initiate aspirin (75-325 mg once daily) and continue in combination with Plavix [see Clinical Studies (14.1)].• For patients with STEMI, the recommended dose of Plavix is 75 mg once daily orally, administered in combination with aspirin (75-325 mg once daily), with or withoutthrombolytics. Plavix may be initiated with or without a loading dose [see Clinical Studies(14.1)].2.2 Recent MI, Recent Stroke, or Established Peripheral Arterial DiseaseThe recommended daily dose of Plavix is 75 mg once daily orally, with or without food [see Clinical Pharmacology (12.3)].2.3 CYP2C19 Poor MetabolizersCYP2C19 poor metabolizer status is associated with diminished antiplatelet response to clopidogrel. Although a higher dose regimen in poor metabolizers increases antiplatelet response [see Clinical Pharmacology (12.5)], an appropriate dose regimen for this patient population has not been established.2.4 Use with Proton Pump Inhibitors (PPI)Omeprazole, a moderate CYP2C19 inhibitor, reduces the pharmacological activity of Plavix. Avoid using omeprazole concomitantly or 12 hours apart with Plavix. Consider using another acid-reducing agent with less CYP2C19 inhibitory activity. A higher dose regimen of clopidogrel concomitantly administered with omeprazole increases antiplatelet response; an appropriate dose regimen has not been established [see Warnings and Precautions (5.1), Drug Interactions (7.1) and Clinical Pharmacology (12.5)].3 DOSAGE FORMS AND STRENGTHS• 75 mg tablets: Pink, round, biconvex, film-coated tablets debossed with “75” on one side and “1171” on the other• 300 mg tablets: Pink, oblong, film-coated tablets debossed with “300” on one side and “1332” on the other4 CONTRAINDICATIONS4.1 Active BleedingPlavix is contraindicated in patients with active pathological bleeding such as peptic ulcer or intracranial hemorrhage.4.2 HypersensitivityPlavix is contraindicated in patients with hypersensitivity (e.g., anaphylaxis) to clopidogrel or any component of the product [see Adverse Reactions (6.2)].5 WARNINGS AND PRECAUTIONS5.1 Diminished Antiplatelet Activity Due to Impaired CYP2C19 FunctionClopidogrel is a prodrug. Inhibition of platelet aggregation by clopidogrel is due to an active metabolite. The metabolism of clopidogrel to its active metabolite can be impaired by genetic variations in CYP2C19 [see Boxed Warning] and by concomitant medications that interfere with CYP2C19. Avoid concomitant use of Plavix and strong or moderate CYP2C19 inhibitors.Omeprazole, a moderate CYP2C19 inhibitor, has been shown to reduce the pharmacological activity of Plavix if given concomitantly or if given 12 hours apart. Consider using anotheracid-reducing agent with less CYP2C19 inhibitory activity. Pantoprazole, a weak CYP2C19 inhibitor, had less effect on the pharmacological activity of Plavix than omeprazole [see Drug Interactions (7.1) and Dosage and Administration (2.4)].5.2 General Risk of BleedingThienopyridines, including Plavix, increase the risk of bleeding. If a patient is to undergo surgery and an antiplatelet effect is not desired, discontinue Plavix five days prior to surgery. In patients who stopped therapy more than five days prior to CABG the rates of major bleeding were similar (event rate 4.4% Plavix + aspirin; 5.3% placebo + aspirin). In patients who remained on therapy within five days of CABG, the major bleeding rate was 9.6% for Plavix + aspirin, and 6.3% for placebo + aspirin.Thienopyridines inhibit platelet aggregation for the lifetime of the platelet (7-10 days), so withholding a dose will not be useful in managing a bleeding event or the risk of bleeding associated with an invasive procedure. Because the half-life of clopidogrel’s active metabolite is short, it may be possible to restore hemostasis by administering exogenous platelets; however, platelet transfusions within 4 hours of the loading dose or 2 hours of the maintenance dose may be less effective.5.3 Discontinuation of PlavixAvoid lapses in therapy, and if Plavix must be temporarily discontinued, restart as soon as possible. Premature discontinuation of Plavix may increase the risk of cardiovascular events. 5.4 Patients with Recent Transient Ischemic Attack (TIA) or StrokeIn patients with recent TIA or stroke who are at high risk for recurrent ischemic events, the combination of aspirin and Plavix has not been shown to be more effective than Plavix alone, but the combination has been shown to increase major bleeding.5.5 Thrombotic Thrombocytopenic Purpura (TTP)TTP, sometimes fatal, has been reported following use of Plavix, sometimes after a short exposure (<2 weeks). TTP is a serious condition that requires urgent treatment including plasmapheresis (plasma exchange). It is characterized by thrombocytopenia, microangiopathic hemolytic anemia (schistocytes [fragmented RBCs] seen on peripheral smear), neurological findings, renal dysfunction, and fever [see Adverse Reactions (6.2)].6 ADVERSE REACTIONSThe following serious adverse reactions are discussed below and elsewhere in the labeling: • Bleeding [see Warnings and Precautions (5.2)]• Thrombotic thrombocytopenic purpura [see Warnings and Precautions (5.5)]6.1 Clinical Studies ExperienceBecause 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 patientstreated for 1 year or more. The clinically important adverse reactions observed in trialscomparing Plavix plus aspirin to placebo plus aspirin and trials comparing Plavix alone to aspirinalone are discussed below.BleedingCUREIn CURE, Plavix use with aspirin was associated with an increase in major bleeding (primarilygastrointestinal and at puncture sites) compared to placebo with aspirin (see Table 1). Theincidence of intracranial hemorrhage (0.1%) and fatal bleeding (0.2%) were the same in bothgroups. Other bleeding events that were reported more frequently in the clopidogrel group wereepistaxis, hematuria, and bruise.The overall incidence of bleeding is described in Table 1.Table 1: CURE Incidence of Bleeding Complications (% patients)PlaceboEvent Plavix(+ aspirin)* (+ aspirin)*(n=6259)(n=6303)§Major bleeding † 3.7 ‡ 2.7Life-threatening bleeding 2.2 1.8Fatal 0.2 0.25 g/dL hemoglobin drop 0.9 0.9Requiring surgical intervention 0.7 0.7strokes 0.1 0.1HemorrhagicRequiringinotropes 0.5 0.5Requiring transfusion (≥4 units) 1.2 1.0Other major bleeding 1.6 1.0disabling 0.4 0.3SignificantlyIntraocular bleeding with 0.05 0.03significant loss of visionRequiring 2-3 units of blood 1.3 0.9Minor bleeding ¶ 5.1 2.4* Other standard therapies were used as appropriate.† Life-threatening and other major bleeding.‡ Major bleeding event rate for Plavix + aspirin was dose-dependent on aspirin: <100 mg = 2.6%;100-200 mg = 3.5%; >200 mg = 4.9%Major bleeding event rates for Plavix + aspirin by age were: <65 years = 2.5%, ≥65 to <75 years= 4.1%, ≥75 years = 5.9%§ Major bleeding event rate for placebo + aspirin was dose-dependent on aspirin: <100 mg = 2.0%;100-200 mg = 2.3%; >200 mg = 4.0%Major bleeding event rates for placebo + aspirin by age were: <65 years = 2.1%, ≥65 to <75 years =3.1%, ≥75 years = 3.6%¶ Led to interruption of study medication.Ninety-two percent (92%) of the patients in the CURE study received heparin or low molecularweight heparin (LMWH), and the rate of bleeding in these patients was similar to the overallresults.COMMITIn COMMIT, similar rates of major bleeding were observed in the Plavix and placebo groups, both of which also received aspirin (see Table 2).Table 2: Incidence of Bleeding Events in COMMIT (% patients)Type of bleeding Plavix(+ aspirin)(n=22961)Placebo(+ aspirin)(n=22891)p-valueMajor* noncerebral or cerebral bleeding** Major noncerebralFatalHemorrhagic strokeFatal 0.60.40.20.20.20.50.30.20.20.20.590.480.900.910.81Other 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 placebo + aspirin by age were: <60 years = 0.4%, ≥60 to <70 years = 0.6%, ≥70 years = 0.7%.CAPRIE (Plavix vs. Aspirin)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.Other bleeding events that were reported more frequently in the Plavix group were epistaxis and hematoma.Other Adverse EventsIn CURE and CHARISMA, which compared Plavix plus aspirin to aspirin alone, there was no differencein the rate of adverse events (other than bleeding) between Plavix and placebo.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.6.2 Postmarketing ExperienceThe 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.• Blood and lymphatic system disorders: Agranulocytosis, aplastic anemia/pancytopenia, thrombotic thrombocytopenic purpura (TTP)• Eye disorders: Eye (conjunctival, ocular, retinal) bleeding• Gastrointestinal disorders: Gastrointestinal and retroperitoneal hemorrhage with fatal outcome, colitis (including ulcerative or lymphocytic colitis), pancreatitis, stomatitis,gastric/duodenal ulcer, diarrhea• General disorders and administration site condition: Fever, hemorrhage of operative wound• Hepato-biliary disorders: Acute liver failure, hepatitis (non-infectious), abnormal liver function test• Immune system disorders: Hypersensitivity reactions, anaphylactoid reactions, serum sickness• Musculoskeletal, connective tissue and bone disorders: Musculoskeletal bleeding, myalgia, arthralgia, arthritis• Nervous system disorders: Taste disorders, fatal intracranial bleeding, headache• Psychiatric disorders: Confusion, hallucinations• Respiratory, thoracic and mediastinal disorders: Bronchospasm, interstitial pneumonitis, respiratory tract bleeding• Renal and urinary disorders: Increased creatinine levels• Skin and subcutaneous tissue disorders: Maculopapular or erythematous rash, urticaria, bullous dermatitis, eczema, toxic epidermal necrolysis, Stevens-Johnson syndrome,angioedema, erythema multiforme, skin bleeding, lichen planus, generalized pruritus • Vascular disorders: Vasculitis, hypotension7 DRUG INTERACTIONS7.1 CYP2C19 InhibitorsClopidogrel is metabolized to its active metabolite in part by CYP2C19. Concomitant use of drugs that inhibit the activity of this enzyme results in reduced plasma concentrations of the active metabolite of clopidogrel and a reduction in platelet inhibition [see Warnings and Precautions (5.1) and Dosage and Administration (2.4)].Proton Pump Inhibitors (PPI)A study was conducted with Plavix (300 mg loading dose followed by 75 mg/day) administered with a high dose (80 mg/day) of omeprazole. As shown in Table 3 below, with concomitant dosing of omeprazole, exposure (C max and AUC) to the clopidogrel active metabolite and platelet inhibition were substantially reduced. Similar reductions in exposure to the clopidogrel active metabolite and platelet inhibition were observed when Plavix and omeprazole were administered 12 hours apart (data not shown).There are no adequate studies of a lower dose of omeprazole or a higher dose of Plavix in comparison with the approved dose of Plavix.A study was conducted using Plavix (300 mg loading dose followed by 75 mg/day) and a high dose (80 mg/day) of pantoprazole, a PPI with less CYP2C19 inhibitory activity than omeprazole. The plasma concentrations of the clopidogrel active metabolite and the degree of platelet inhibition were less than observed with Plavix alone but were greater than observed when omeprazole 80 mg was co-administered with 300 mg loading dose followed by 75 mg/day of Plavix (Table 3).Table 3: Comparison of Clopidogrel Active Metabolite Exposure and Platelet Inhibition with and without Proton Pump Inhibitors, Omeprazole and Pantoprazole% Change from Plavix (300 mg/75 mg) alone Plavix plus C max (ng/mL) AUC Platelet Inhibition† (%)Day 1 Day 5 Day 1 Day 5** Day 1 Day 5 Omeprazole* 80 mg ↓46% ↓42% ↓45% ↓40% ↓39% ↓21% Pantoprazole 80 mg ↓24% ↓28% ↓20% ↓14% ↓15% ↓11% †Inhibition of platelet aggregation with 5 mcM ADP*Similar results seen when Plavix and omeprazole were administered 12 hours apart.**AUC at Day 5 is AUC0-247.2 Nonsteroidal Anti-Inflammatory Drugs (NSAIDs)Coadministration of Plavix and NSAIDs increases the risk of gastrointestinal bleeding.7.3 Warfarin (CYP2C9 Substrates)Although the administration of clopidogrel 75 mg per day did not modify the pharmacokinetics of S-warfarin (a CYP2C9 substrate) or INR in patients receiving long-term warfarin therapy, coadministration of Plavix with warfarin increases the risk of bleeding because of independent effects on hemostasis.However, at high concentrations in vitr o, clopidogrel inhibits CYP2C9.8 USE IN SPECIFIC POPULATIONS8.1 PregnancyPregnancy Category BReproduction studies performed in rats and rabbits at doses up to 500 and 300 mg/kg/day, respectively (65 and 78 times the recommended daily human dose, respectively, on a mg/m2 basis), revealed no evidence of impaired fertility or fetotoxicity due to clopidogrel. There are, however, no adequate and well-controlled studies in pregnant women. Because animal reproduction studies are not always predictive of a human response, Plavix should be used during pregnancy only if clearly needed.8.3 Nursing MothersStudies in rats have shown that clopidogrel and/or its metabolites are excreted in the milk. It is not known whether this drug is excreted in human milk. Because many drugs are excreted in human milk and because of the potential for serious adverse reactions in nursing infants from clopidogrel, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother.8.4 Pediatric UseSafety and effectiveness in the pediatric population have not been established.8.5 Geriatric UseOf the total number of subjects in the CAPRIE and CURE controlled clinical studies, approximately 50% of patients treated with Plavix were 65 years of age and older, and 15% were 75 years and older. In COMMIT, approximately 58% of the patients treated with Plavix were 60 years and older, 26% of whom were 70 years and older.The observed risk of bleeding events with Plavix plus aspirin versus placebo plus aspirin by age category is provided in Table 1 and Table 2 for the CURE and COMMIT trials, respectively [see Adverse Reactions (6.1)]. No dosage adjustment is necessary in elderly patients.8.6 Renal ImpairmentExperience is limited in patients with severe and moderate renal impairment [see Clinical Pharmacology (12.2)].8.7 Hepatic ImpairmentNo dosage adjustment is necessary in patients with hepatic impairment [see Clinical Pharmacology (12.2)].10 OVERDOSAGEPlatelet inhibition by Plavix is irreversible and will last for the life of the platelet. Overdose following clopidogrel administration may result in bleeding complications. A single oral dose of clopidogrel at 1500 or 2000 mg/kg was lethal to mice and to rats and at 3000 mg/kg to baboons. Symptoms of acute toxicity were vomiting, prostration, difficult breathing, and gastrointestinal hemorrhage in animals.Based on biological plausibility, platelet transfusion may restore clotting ability.11 DESCRIPTIONPlavix (clopidogrel bisulfate) is a thienopyridine class inhibitor of P2Y12 ADP platelet receptors. Chemically it is methyl (+)-(S)-α-(2-chlorophenyl)-6,7-dihydrothieno[3,2-c]pyridine-5(4H)acetate sulfate (1:1). The empirical formula of clopidogrel bisulfate is C16H16ClNO2S•H2SO4 and its molecular weight is 419.9.The structural formula is as follows:Clopidogrel bisulfate is a white to off-white powder. It is practically insoluble in water at neutral pH but freely soluble at pH 1. It also dissolves freely in methanol, dissolves sparingly in methylene chloride, and is practically insoluble in ethyl ether. It has a specific optical rotation of about +56°.Plavix for oral administration is provided as either pink, round, biconvex, debossed, film-coated tablets containing 97.875 mg of clopidogrel bisulfate which is the molar equivalent of 75 mg of clopidogrel base or pink, oblong, debossed film-coated tablets containing 391.5 mg of clopidogrel bisulfate which is the molar equivalent of 300 mg of clopidogrel base.Each tablet contains hydrogenated castor oil, hydroxypropylcellulose, mannitol, microcrystalline cellulose and polyethylene glycol 6000 as inactive ingredients. The pink film coating contains ferric oxide, hypromellose 2910, lactose monohydrate, titanium dioxide and triacetin. The tablets are polished with Carnauba wax.12 CLINICAL PHARMACOLOGY12.1 Mechanism of ActionClopidogrel is an inhibitor of platelet activation and aggregation through the irreversible binding of its active metabolite to the P2Y12 class of ADP receptors on platelets.12.2 PharmacodynamicsClopidogrel must be metabolized by CYP450 enzymes to produce the active metabolite that inhibits platelet aggregation. The active metabolite of clopidogrel selectively inhibits the binding of adenosine diphosphate (ADP) to its platelet P2Y12 receptor and the subsequentADP-mediated activation of the glycoprotein GPIIb/IIIa complex, thereby inhibiting platelet aggregation. This action is irreversible. Consequently, platelets exposed to clopidogrel’s active metabolite are affected for the remainder of their lifespan (about 7 to 10 days). Platelet aggregation induced by agonists other than ADP is also inhibited by blocking the amplification of platelet activation by released ADP.Dose-dependent inhibition of platelet aggregation can be seen 2 hours after single oral doses of Plavix. Repeated doses of 75 mg Plavix per day inhibit ADP-induced platelet aggregation on the first day, and inhibition reaches steady state between Day 3 and Day 7. At steady state, the average inhibition level observed with a dose of 75 mg Plavix per day was between 40% and 60%. Platelet aggregation and bleeding time gradually return to baseline values after treatment is discontinued, generally in about 5 days.Geriatric PatientsElderly (≥75 years) and young healthy subjects had similar effects on platelet aggregation. Renally-Impaired PatientsAfter repeated doses of 75 mg Plavix per day, patients with severe renal impairment (creatinine clearance from 5 to 15 mL/min) and moderate renal impairment (creatinine clearance from 30 to 60 mL/min) showed low (25%) inhibition of ADP-induced platelet aggregation.。
