每日1次曲唑酮制剂Oleptro获准用于治疗成人抑郁症
2010年2月3日,Labopharm公司宣布,美国食品药品管理局(FDA)已批准Oleptro (盐酸曲唑酮)用于治疗成人抑郁症(MDD)。Oleptro为缓释片剂,每日服用1次。

FDA批准Oleptro是基于对单相MDD患者进行的一项关键性研究的结果,该研究历时8周,为随机、双盲、2个亚组、多中心研究。其主要有效性终点为比较Oleptro治疗组与安慰剂对照组自基线起至研究结束时汉密尔顿抑郁量表(HAMD-17)总分的变化。主要终点达到统计学意义(P =0.012)。

此研究的总中止率为25%(安慰剂对照组为21%,Oleptro治疗组为30%)。Oleptro治疗组有4%的患者因嗜睡或镇静而中止治疗。

Oleptro最常见的不良反应为头晕、便秘、视物模糊以及嗜睡/镇静。药品说明书中包含一黑框警告,指出儿童、青少年及青年人因重度抑郁症及其他精神疾病接受抗抑郁药治疗后,有出现自杀意念及行为的风险。Oleptro尚未获准用于治疗儿科患者。

Labopharm公司于2010年将Oleptro作为处方药推向美国市场。

Manufacturer:

Labopharm, Inc.

Pharmacological Class:

Triazolopyridine

Active Ingredient(s):

Trazodone HCl 150mg, 300mg; scored ext-rel tabs.

Indication(s):

Major depressive disorder.

Pharmacology:

Trazodone is believed to exert its antidepressant effects by potentiating serotonergic activity through selective inhibition of neuronal reuptake of serotonin. Trazodone also acts as an antagonist at the serotonin 5-HT2A/2C receptors. Activation of serotonin 5-HT2A/2C receptors, which studies have shown to be upregulated in patients with depression, inhibits dopamine and norepinephrine release which may contribute to depression. Trazodone does not stimulate the CNS.

Clinical Trials:

A randomized, double-blind, multicenter, two-arm trial was conducted to assess the efficacy of Oleptro in patients with unipolar major depressive disorder. The study, which randomized 412 adult patients, demonstrated a statistically significant difference in the Hamilton Rating Scale for Depression (HAMD-17) total score change from baseline at eight weeks between the Oleptro and placebo groups.

Legal Classification:

Rx

Adults:

May be swallowed whole or broken in half along the scored line; do not crush or chew. Take on empty stomach at bedtime. ≥18yrs: Initially 150mg once daily. May increase by 75mg/day at 3-day intervals; max 375mg/day.

Children:

<18yrs: not recommended.

Warnings/Precautions:

Monitor for clinical worsening, suicidality and unusual changes in behavior, esp. during initiation and dose changes. Acute post MI: not recommended. Monitor for serotonin syndrome or neuroleptic malignant syndrome-like symptoms; discontinue if occurs. Bipolar disorder. Mania/hypomania. Psychosis. Cardiovascular disease. Predisposition to QT prolongation. Hypokalemia. Hypomagnesemia. Renal or hepatic impairment. Volume depletion. Predisposition to priapism (eg, sickle cell anemia, multiple myeloma, leukemia, or anatomically deformed penis). Write Rx for smallest practical amount. Reevaluate periodically. Avoid abrupt cessation. Elderly. Pregnancy (Cat.C). Nursing mothers.

Interaction(s):

Do not use during or within 14 days of MAOIs. Concomitant trytophan: not recommended. Potentiates alcohol, barbiturates, other CNS depressants, digoxin, phenytoin, antihypertensives. Potentiated by CYP3A4 inhibitors (eg, ritonavir, indinavir, ketoconazole, itraconazole). Increased risk of arrhythmias with concomitant potent CYP3A4 inhibitors or drugs that prolong the QT interval; consider lower trazodone dose. Antagonized by CYP3A4 inducers (eg, carbamazepine). Increased risk of bleeding with concomitant NSAIDs, aspirin, anticoagulants. Monitor for serotonin syndrome with SSRIs, SNRIs, triptans (esp. during initiation and dose increases), MAOIs, antipsychotics, antidopaminergic agents. Monitor PT with warfarin. Increased risk of hyponatremia with diuretics.

Adverse Reaction(s):

Somnolence/sedation, dizziness, constipation, blurred vision, headache, anticholinergic effects, GI upset, fatigue, myalgia, hypotension, syncope, hyponatremia, sexual dysfunction, CNS disturbances, dyspnea, night sweats, QT prolongation, torsades de pointes (possible); rare: priapism (discontinue if occurs).
