These studies did not show an increase in the risk of suicidal thoughts and behavior with antidepressant use in patients over age 24; there was a reduction in risk with antidepressant use in patients aged 65 and older [see Warnings and Precautions (5.1)].In patients of all ages who are started on antidepressant therapy, monitor closely for worsening, and for emergence of suicidal thoughts and behaviors. Advise families and caregivers of the need for close observation and communication with the prescriber [see Warnings and Precautions (5.1)].Cymbalta is not approved for use in pediatric patients [see Use in Specific Populations (8.4)].USAGEAND1 INDICATIONS1.1 Major Depressive DisorderCymbalta is indicated for the treatment of major depressive disorder (MDD). The efficacy of Cymbalta was established in four short-term and one maintenance trial in adults [see Clinical Studies (14.1)].A major depressive episode (DSM-IV) implies a prominent and relatively persistent (nearly every day for at least 2 weeks) depressed or dysphoric mood that usually interferes with daily functioning, and includes at least 5 of the following 9 symptoms: depressed mood, loss of interest in usual activities, significant change in weight and/or appetite, insomnia or hypersomnia, psychomotor agitation or retardation, increased fatigue, feelings of guilt or worthlessness, slowed thinking or impaired concentration, or a suicide attempt or suicidal ideation.AnxietyDisorder1.2 GeneralizedCymbalta is indicated for the treatment of generalized anxiety disorder (GAD). The efficacy of Cymbalta was established in three short-term trials and one maintenance trial in adults [see Clinical Studies (14.2)].Generalized anxiety disorder is defined by the DSM-IV as excessive anxiety and worry, present more days than not, for at least 6 months. The excessive anxiety and worry must be difficult to control and must cause significant distress or impairment in normal functioning. It must be associated with at least 3 of the following 6 symptoms: restlessness or feeling keyed up or on edge, being easily fatigued, difficulty concentrating or mind going blank, irritability, muscle tension, and/or sleep disturbance.1.3 Diabetic Peripheral Neuropathic PainCymbalta is indicated for the management of neuropathic pain (DPNP) associated with diabetic peripheral neuropathy [see Clinical Studies (14.3)].1.4 FibromyalgiaCymbalta is indicated for the management of fibromyalgia (FM) [see Clinical Studies (14.4)].PainMusculoskeletal1.5 ChronicCymbalta is indicated for the management of chronic musculoskeletal pain. This has been established in studies in patients with chronic low back pain (CLBP) and chronic pain due to osteoarthritis [see Clinical Studies (14.5)].2 DOSAGE AND ADMINISTRATIONCymbalta should be swallowed whole and should not be chewed or crushed, nor should the capsule be opened and its contents sprinkled on food or mixed with liquids. All of these might affect the enteric coating. Cymbalta can be given without regard to meals.Treatment2.1 InitialMajor Depressive Disorder — Cymbalta should be administered at a total dose of 40 mg/day (given as 20 mg twice daily) to 60 mg/day (given either once daily or as 30 mg twice daily). For some patients, it may be desirable to start at 30 mg once daily for 1 week, to allow patients to adjust to the medication before increasing to 60 mg once daily. While a 120 mg/day dose was shown to be effective, there is no evidence that doses greater than 60 mg/day confer any additional benefits. The safety of doses above 120 mg/day has not been adequately evaluated [see Clinical Studies (14.1)].Generalized Anxiety Disorder — For most patients, the recommended starting dose for Cymbalta is 60 mg administered once daily. For some patients, it may be desirable to start at 30 mg once daily for 1 week, to allow patients to adjust to the medication before increasing to 60 mg once daily. While a 120 mg once daily dose was shown to be effective, there is no evidence that doses greater than 60 mg/day confer additional benefit. Nevertheless, if a decision is made to increase the dose beyond 60 mg once daily, dose increases should be in increments of 30 mg once daily. The safety of doses above 120 mg once daily has not been adequately evaluated [see Clinical Studies (14.2)].Diabetic Peripheral Neuropathic Pain — The recommended dose for Cymbalta is 60 mg administered once daily. There is no evidence that doses higher than 60 mg confer additional significant benefit and the higher dose is clearly less well tolerated [see Clinical Studies (14.3)]. For patients for whom tolerability is a concern, a lower starting dose may be considered.Since diabetes is frequently complicated by renal disease, a lower starting dose and gradual increase in dose should be considered for patients with renal impairment [see Dosage and Administration (2.3), Use in Specific Populations (8.10), and Clinical Pharmacology (12.3)].Fibromyalgia — The recommended dose for Cymbalta is 60 mg administered once daily. Treatment should begin at 30 mg once daily for 1 week, to allow patients to adjust to the medication before increasing to 60 mg once daily. Some patients may respond to the starting dose. There is no evidence that doses greater than 60 mg/day confer additional benefit, even in patients who do not respond to a 60 mg dose, and higher doses are associated with a higher rate of adverse reactions [see Clinical Studies (14.4)].Chronic Musculoskeletal Pain — The recommended dose for Cymbalta is 60 mg once daily. Dosing may be started at 30 mg for one week, to allow patients to adjust to the medication before increasing to 60 mg once daily. There is no evidence that higher doses confer additional benefit, even in patients who do not respond to a 60 mg dose, and higher doses are associated with a higher rate of adverse reactions [see Clinical Studies (14.5)].Treatment2.2 M aintenance/Continuation/ExtendedMajor Depressive Disorder — It is generally agreed that acute episodes of major depression require several months or longer of sustained pharmacologic therapy. Maintenance of efficacy in MDD was demonstrated with Cymbalta as monotherapy. Cymbalta should be administered at a total dose of 60 mg once daily. Patients should be periodically reassessed to determine the need for maintenance treatment and the appropriate dose for such treatment [see Clinical Studies (14.1)].Generalized Anxiety Disorder — It is generally agreed that episodes of generalized anxiety disorder require several months or longer of sustained pharmacological therapy. Maintenance of efficacy in GAD was demonstrated with Cymbalta as monotherapy. Cymbalta should be administered in a dose range of 60-120 mg once daily. Patients should be periodically reassessed to determine the continued need for maintenance treatment and the appropriate dose for such treatment [see Clinical Studies (14.2)].Diabetic Peripheral Neuropathic Pain — As the progression of diabetic peripheral neuropathy is highly variable and management of pain is empirical, the effectiveness of Cymbalta must be assessed individually. Efficacy beyond 12 weeks has not been systematically studied in placebo-controlled trials.Fibromyalgia — Fibromyalgia is recognized as a chronic condition. The efficacy of Cymbalta in the management of fibromyalgia has been demonstrated in placebo-controlled studies up to 3 months. The efficacy of Cymbalta was not demonstrated in longer studies; however, continued treatment should be based on individual patient response.Chronic Musculoskeletal Pain — The efficacy of Cymbalta has not been established in placebo-controlled studies beyond 13 weeks.2.3 Dosing in Special PopulationsHepatic Insufficiency — It is recommended that Cymbalta should ordinarily not be administered to patients with any hepatic insufficiency [see Warnings and Precautions (5.13) and Use in Specific Populations (8.9)].Severe Renal Impairment — Cymbalta is not recommended for patients with end-stage renal disease or severe renal impairment (estimated creatinine clearance <30 mL/min) [see Warnings and Precautions (5.13) and Use in Specific Populations (8.10)].Elderly Patients — No dose adjustment is recommended for elderly patients on the basis of age. As with any drug, caution should be exercised in treating the elderly. When individualizing the dosage in elderly patients, extra care should be taken when increasing the dose [see Use in Specific Populations (8.5)].Pregnant Women — There are no adequate and well-controlled studies in pregnant women; therefore, Cymbalta should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus [see Use in Specific Populations (8.1)].Lilly maintains a pregnancy registry to monitor the pregnancy outcomes of women exposed to Cymbalta while pregnant. Healthcare providers are encouraged to register any patient who is exposed to Cymbalta during pregnancy by calling the Cymbalta Pregnancy Registry at 1-866-814-6975 or by visiting Nursing Mothers — Because the safety of duloxetine in infants is not known, nursing while on Cymbalta is not recommended [see Use in Specific Populations (8.3)].2.4 D iscontinuingCymbaltaSymptoms associated with discontinuation of Cymbalta and other SSRIs and SNRIs have been reported. A gradual reduction in the dose rather than abrupt cessation is recommended whenever possible [see Warnings and Precautions (5.7)].2.5 Switching a Patient To or From a Monoamine Oxidase Inhibitor (MAOI) Intended to Treat PsychiatricDisordersAt least 14 days should elapse between discontinuation of an MAOI intended to treat psychiatric disorders and initiation of therapy with Cymbalta. Conversely, at least 5 days should be allowed after stopping Cymbalta before starting an MAOI intended to treat psychiatric disorders [see Contraindications (4.1)].2.6 Use of Cymbalta with Other MAOIs such as Linezolid or Methylene BlueDo not start Cymbalta in a patient who is being treated with linezolid or intravenous methylene blue because there is an increased risk of serotonin syndrome. In a patient who requires more urgent treatment of a psychiatric condition, other interventions, including hospitalization, should be considered [see Contraindications (4.1)].In some cases, a patient already receiving Cymbalta therapy may require urgent treatment with linezolid or intravenous methylene blue. If acceptable alternatives to linezolid or intravenous methylene blue treatment are not available and the potential benefits of linezolid or intravenous methylene blue treatment are judged to outweigh the risks of serotonin syndrome in a particular patient, Cymbalta should be stopped promptly, and linezolid or intravenous methylene blue can be administered. The patient should be monitored for symptoms of serotonin syndrome for 5 days or until 24 hours after the last dose of linezolid or intravenous methylene blue, whichever comes first. Therapy with Cymbalta may be resumed 24 hours after the last dose of linezolid or intravenous methylene blue [see Warnings and Precautions (5.4)].The risk of administering methylene blue by non-intravenous routes (such as oral tablets or by local injection) or in intravenous doses much lower than 1 mg/kg with Cymbalta is unclear. The clinician should, nevertheless, be aware of the possibility of emergent symptoms of serotonin syndrome with such use [see Warnings and Precautions (5.4)].3 DOSAGE FORMS AND STRENGTHSCymbalta is available as delayed release capsules:20 mg opaque green capsules imprinted with “Lilly 3235 20mg”30 mg opaque white and blue capsules imprinted with “Lilly 3240 30mg”60 mg opaque green and blue capsules imprinted with “Lilly 3237 60mg”60 mg opaque green and blue capsules imprinted with “Lilly 3270 60mg”4 CONTRAINDICATIONS4.1 Monoamine Oxidase Inhibitors (MAOIs)The use of MAOIs intended to treat psychiatric disorders with Cymbalta or within 5 days of stopping treatment with Cymbalta is contraindicated because of an increased risk of serotonin syndrome. The use of Cymbalta within 14 days of stopping an MAOI intended to treat psychiatric disorders is also contraindicated [see Dosage and Administration (2.5) and Warnings and Precautions (5.4)].Starting Cymbalta in a patient who is being treated with MAOIs such as linezolid or intravenous methylene blue is also contraindicated because of an increased risk of serotonin syndrome [see Dosage and Administration (2.6) and Warnings and Precautions (5.4)].4.2 Uncontrolled Narrow-Angle GlaucomaIn clinical trials, Cymbalta use was associated with an increased risk of mydriasis; therefore, its use should be avoided in patients with uncontrolled narrow-angle glaucoma [see Warnings and Precautions (5.13)].PRECAUTIONS5 WARNINGSAND5.1 Suicidal Thoughts and Behaviors in Adolescents and Young AdultsPatients with major depressive disorder (MDD), both adult and pediatric, may experience worsening of their depression and/or the emergence of suicidal ideation and behavior (suicidality) or unusual changes in behavior, whether or not they are taking antidepressant medications, and this risk may persist until significant remission occurs. Suicide is a known risk of depression and certain other psychiatric disorders, and these disorders themselves are the strongest predictors of suicide. There has been a long-standing concern, however, that antidepressants may have a role in inducing worsening of depression and the emergence of suicidality in certain patients during the early phases of treatment.Pooled analyses of short-term placebo-controlled trials of antidepressant drugs (SSRIs and others) showed that these drugs increase the risk of suicidal thinking and behavior (suicidality) in children, adolescents, and young adults (ages 18-24) with major depressive disorder (MDD) and other psychiatric disorders. Short-term studies did not show an increase in the risk of suicidality with antidepressants compared to placebo in adults beyond age 24; there was a reduction with antidepressants compared to placebo in adults aged 65 and older.The pooled analyses of placebo-controlled trials in children and adolescents with MDD, obsessive compulsive disorder (OCD), or other psychiatric disorders included a total of 24 short-term trials of 9 antidepressant drugs in over 4400 patients. The pooled analyses of placebo-controlled trials in adults with MDD or other psychiatric disorders included a total of 295 short-term trials (median duration of 2 months) of 11 antidepressant drugs in over 77,000 patients. There was considerable variation in risk of suicidality among drugs, but a tendency toward an increase in the younger patients for almost all drugs studied. There were differences in absolute risk of suicidality across the different indications, with the highest incidence in MDD. The risk of differences (drug vs placebo), however, were relatively stable within age strata and across indications. These risk differences (drug-placebo difference in the number of cases of suicidality per 1000 patients treated) are provided in Table 1.Table 1Age Range Drug-Placebo Difference in Number of Cases ofSuicidality per 1000 Patients TreatedIncreases Compared to Placebo<18 14 additional cases18-24 5 additional cases Decreases Compared to Placebo25-64 1 fewer case≥65 6 fewer casesNo suicides occurred in any of the pediatric trials. There were suicides in the adult trials, but the number was notsufficient to reach any conclusion about drug effect on suicide.It is unknown whether the suicidality risk extends to longer-term use, i.e., beyond several months. However, thereis substantial evidence from placebo-controlled maintenance trials in adults with depression that the use ofantidepressants can delay the recurrence of depression.All patients being treated with antidepressants for any indication should be monitored appropriately andobserved closely for clinical worsening, suicidality, and unusual changes in behavior, especially during the initialfew months of a course of drug therapy, or at times of dose changes, either increases or decreases.The following symptoms, anxiety, agitation, panic attacks, insomnia, irritability, hostility, aggressiveness,impulsivity, akathisia (psychomotor restlessness), hypomania, and mania, have been reported in adult and pediatricpatients being treated with antidepressants for major depressive disorder as well as for other indications, both psychiatricand nonpsychiatric. Although a causal link between the emergence of such symptoms and either the worsening ofdepression and/or the emergence of suicidal impulses has not been established, there is concern that such symptomsmay represent precursors to emerging suicidality.Consideration should be given to changing the therapeutic regimen, including possibly discontinuing themedication, in patients whose depression is persistently worse, or who are experiencing emergent suicidality or symptomsthat might be precursors to worsening depression or suicidality, especially if these symptoms are severe, abrupt in onset,or were not part of the patient’s presenting symptoms.If the decision has been made to discontinue treatment, medication should be tapered, as rapidly as is feasible,but with recognition that discontinuation can be associated with certain symptoms [see Dosage and Administration (2.4)and Warnings and Precautions (5.7) for descriptions of the risks of discontinuation of Cymbalta].Families and caregivers of patients being treated with antidepressants for major depressive disorder orother indications, both psychiatric and nonpsychiatric, should be alerted about the need to monitor patients for the emergence of agitation, irritability, unusual changes in behavior, and the other symptoms described above, as well as the emergence of suicidality, and to report such symptoms immediately to health care providers. Such monitoring should include daily observation by families and caregivers. Prescriptions for Cymbalta should bewritten for the smallest quantity of capsules consistent with good patient management, in order to reduce therisk of overdose.Screening Patients for Bipolar Disorder — A major depressive episode may be the initial presentation of bipolardisorder. It is generally believed (though not established in controlled trials) that treating such an episode with anantidepressant alone may increase the likelihood of precipitation of a mixed/manic episode in patients at risk for bipolardisorder. Whether any of the symptoms described above represent such a conversion is unknown. However, prior toinitiating treatment with an antidepressant, patients with depressive symptoms should be adequately screened todetermine if they are at risk for bipolar disorder; such screening should include a detailed psychiatric history, including afamily history of suicide, bipolar disorder, and depression. It should be noted that Cymbalta (duloxetine) is not approvedfor use in treating bipolar depression.5.2 HepatotoxicityThere have been reports of hepatic failure, sometimes fatal, in patients treated with Cymbalta. These cases havepresented as hepatitis with abdominal pain, hepatomegaly, and elevation of transaminase levels to more than twenty times the upper limit of normal with or without jaundice, reflecting a mixed or hepatocellular pattern of liver injury. Cymbalta should be discontinued in patients who develop jaundice or other evidence of clinically significant liver dysfunction and should not be resumed unless another cause can be established.Cases of cholestatic jaundice with minimal elevation of transaminase levels have also been reported. Otherpostmarketing reports indicate that elevated transaminases, bilirubin, and alkaline phosphatase have occurred in patientswith chronic liver disease or cirrhosis.Cymbalta increased the risk of elevation of serum transaminase levels in development program clinical trials. Livertransaminase elevations resulted in the discontinuation of 0.3% (89/29,435) of Cymbalta-treated patients. In mostpatients, the median time to detection of the transaminase elevation was about two months. In placebo-controlled trials in any indication, for patients with normal and abnormal baseline ALT values, elevation of ALT >3 times the upper limit of normal occurred in 1.37% (132/9611) of Cymbalta-treated patients compared to 0.49% (35/7182) of placebo-treated patients. In placebo-controlled studies using a fixed dose design, there was evidence of a dose response relationship for ALT and AST elevation of >3 times the upper limit of normal and >5 times the upper limit of normal, respectively.。

盐酸度洛西汀肠溶胶囊项目立项论证意见稿1.简介盐酸度洛西汀(duloxetine hydrochloride/Cymbaha，以下简称为度洛西汀)是美国礼来Eli Lilly公司开发的一个5一羟色胺和去甲肾上腺素再摄取抑制剂。
5一羟色胺和去甲肾上腺素均属中枢神经递质，在调控情感和对疼痛的敏度方面起着重要作用。
度洛西汀能够抑制神经元对5一羟色胺和去甲肾上腺素的再摄取，由此提高这两种中枢神经递质在大脑和脊髓中的浓度，故可用于治疗某些心境疾病如抑郁症和焦虑症以及缓解中枢性疼痛如糖尿病外周神经病性疼痛和妇女纤维肌痛等。
度洛西汀也能作用于尿道中的5一羟色胺和去甲肾上腺素受体，从而增强尿道括约肌的神经性紧张程度和收缩能力，所以对妇女应激性尿失禁症治疗也有效。
度洛西汀为口服肠溶胶囊制剂，2004年8月首次在美国获得批准后，现已在70余个国家上市。
度洛西汀2006年的全球销售额即超过13亿美元，2007年和2008年的销售额又分别大幅增至2l亿和27亿美元，是近年世界范围内销售额增长最快的药物之一。

在2个研究中患者随机分为度洛西汀每日每次60mg剂量组(N分别为123和128)或安慰剂组(N分别为122和=139)进行为期9周的治疗；在第3个研究中，患者随机分为度洛西汀20或40mg每日2次剂量组(N分别为86和91)或安慰剂组(N=89) 进行为期8周的治疗；在第3个研究中，患者随机分为度洛西汀40或60mg每日2次剂量组(N分别为95和93)或安慰剂组(N=93) 进行为期8周的治疗。
每日给药剂量超过60mg未见有其他的益处。
在所有4个研究中，通过改进的17项汉密顿抑郁量表总评分表明，度洛西汀的疗效优于安慰剂。
分析治疗的结果和年龄、性别以及种族并未见患者间治疗上的差异。
2、治疗糖尿病性周围神经病引起疼痛在2个的随机、12周、双盲法、安慰剂对照、固定剂量以研究度洛西汀治疗成人糖尿病性周围神经病引起疼痛患者病情至少6月的有效性的临床研究。
研究1和研究2中所有参加的患者为791例，592 例(75%)完成研究。
参加的患者诊断为I或I型糖尿病伴随远端对称的感觉运动多发性神经病疼痛至少6月，患者基于11点的评分标准(0-10，0为没有疼痛，10为最严重的疼痛) 的基准的疼痛评分≥4。
患者必要时每日可服用4g的对乙酰氨基酚缓解疼痛，此外，每天记录患者的疼痛。
盐酸度洛西汀肠溶胶囊
临床试验
4个随机、双盲、安慰剂对照、固定剂量的临床研究评估了本品治疗抑郁障碍的疗效。入组对象为成年门诊病 人，年龄18-83岁，均符合DSM-IV关于重度抑郁障碍的诊断标准。在其中2项研究中，患者被随机分入盐酸度洛西 汀胶囊组60mg每日一次（分别为123例和128例）或安慰剂组（分别为122例和139例）治疗9周；第3项研究中， 患者被随机分入盐酸度洛西汀胶囊组20mg或40mg每日二次（分别为86例和91例）或安慰剂组（89例）治疗8周； 第4项研究中，患者被随机分入盐酸度洛西汀胶囊组40mg或60mg每日二次（分别为95例和93例）或安慰剂组（93 例）治疗8周。没有证据表明盐酸度洛西汀胶囊日剂量超过60mg时有更多益处。
在排除梗阻的情况下，通常认为转氨酶升高伴有胆红素升高，是严重肝脏损害的重要指标。国外临床试验中， 3名服用度洛西汀的患者，出现转氨酶、胆红素和碱性磷酸酶升高，提示存在梗阻情况。上述患者有严重的过度饮 酒的情况，这可能是出现上述异常指标的原因所在。两名安慰剂治疗的患者也出现了转氨酶、胆红素升高的情况。 上市后报告显示转氨酶、胆红素和碱性磷酸酶升高也可以发生在患有慢性肝病或肝硬化患者中。因为度洛西汀和 酒精的相互作用可能引起肝损害或者加剧已有的肝病恶化，所以度洛西汀通常不用于有习惯性饮酒和慢性肝病患 者的治疗。
适应症
用于治疗抑郁症。
规格
(1)30mg；(2)60mg（以度洛西汀计）。
盐酸度洛西丁
作用机制
盐酸度洛西汀是一种5HT/去甲肾上腺素再摄取抑制剂，通过抑制5HT和去甲肾上腺素再摄取来提高这些神经 递质的含量，起到抗抑郁的作用。度洛西汀对抑郁症的其他躯体症状如全身疼痛和胃肠紊乱有疗效，因而比抗抑 郁药物具有优势，这些症状在现有常规疗法中未予治疗。
市场前景
Frost & Sullivan最新的健康战略分析预测，到2006年，美国抗抑郁症药物的收入最高可达140亿美元。度 洛西汀有望在2003年底正式进入美国市场销售。分析家预测，到2006年，度洛西汀年度最高销售额可达6亿美元。

虽然新型抗抑郁剂不断上市，但5-羟色胺再摄制抑制剂的销售量约占全部抗抑郁剂的一半，且治疗成本较低； 再之度洛西汀具有新型的作用机制，即抑制去甲肾上腺素的再摄取。所以在我国开发度洛西汀有着良好前景。度 洛西汀在中国尚无销售数据，预计至中国上市头一年市场份额将占国内5亿元抗抑郁药市场的1%；按照本类药在 世界范围内的递增速度，在2009年将在国内达到5000万～1亿元人民币。它必产生很大的社会效益及经济效益。
