Remeron (Mirtazapine) - Summary


Suicidality and Antidepressant Drugs

Antidepressants increased the risk compared to placebo of suicidal thinking and behavior (suicidality) in children, adolescents, and young adults in short-term studies of major depressive disorder (MDD) and other psychiatric disorders. Anyone considering the use of REMERON® (mirtazapine) Tablets or any other antidepressant in a child, adolescent, or young adult must balance this risk with the clinical need. 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 in risk with antidepressants compared to placebo in adults aged 65 and older. Depression and certain other psychiatric disorders are themselves associated with increases in the risk of suicide. Patients of all ages who are started on antidepressant therapy should be monitored appropriately and observed closely for clinical worsening, suicidality, or unusual changes in behavior. Families and caregivers should be advised of the need for close observation and communication with the prescriber. REMERON® is not approved for use in pediatric patients. (See WARNINGS: Clinical Worsening and Suicide Risk, PRECAUTIONS: Information for Patients, and PRECAUTIONS: Pediatric Use)



REMERON® (mirtazapine) Tablets are an orally administered drug. Mirtazapine has a tetracyclic chemical structure and belongs to the piperazino-azepine group of compounds. It is designated 1,2,3,4,10,14b-hexahydro-2-methylpyrazino [2,1-a] pyrido [2,3-c] benzazepine and has the empirical formula of C17H19N3.

REMERON® (mirtazapine) Tablets are indicated for the treatment of major depressive disorder.

The efficacy of REMERON® in the treatment of major depressive disorder was established in six week controlled trials of outpatients whose diagnoses corresponded most closely to the Diagnostic and Statistical Manual of Mental Disorders – 3rd edition (DSM-III) category of major depressive disorder (see CLINICAL PHARMACOLOGY).

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 five of the following nine 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, a suicide attempt or suicidal ideation.

The effectiveness of REMERON® in hospitalized depressed patients has not been adequately studied.

The efficacy of REMERON® in maintaining a response in patients with major depressive disorder for up to 40 weeks following 8–12 weeks of initial open-label treatment was demonstrated in a placebo-controlled trial. Nevertheless, the physician who elects to use REMERON® for extended periods should periodically re-evaluate the long-term usefulness of the drug for the individual patient (see CLINICAL PHARMACOLOGY).

Clinical Trials Related to Remeron (Mirtazapine)

Phase II Study of Remeron for Cancer Patients Losing More Than 10% of Their Body Weight [Recruiting]
The purpose of this study is to find out if remeron, also called mirtazapine, can help you prevent weight loss while on treatment for your cancer. Remeron is currently used to treat depression and has not been approved by the Food and Drug Administration for use to treat weight loss.

A Placebo-Controlled Study of Mirtazapine for PTSD in OIF/OEF Veterans and Veterans From All Other Southwest Asia Conditions [Recruiting]
The primary objective is to evaluate the efficacy and tolerability of mirtazapine (Remeron) in the treatment of PTSD. Primary Hypothesis to be tested: Veterans with PTSD will have improvement in their symptomatology after 8 weeks of treatment with mirtazapine compared to those treated with placebo. After completion of the placebo-controlled phase, patients who agree to continue in the study will be treated with open-label mirtazapine for an additional 8 weeks.

Study of Indoleamine 2,3-dioxygenase Activity and Mirtazapine Efficacy in Fibromyalgia Syndrome [Recruiting]
This study aims to investigate the anti-nociceptive biogenic amine (serotonin [5-hydroxytryptamine; 5-HT], norepinephrine [NE], dopamine [DA], and their metabolites) status in Thai fibromyalgia syndrome (FMS) patients compared with a representative Thai population. The efficacy and the tolerability of mirtazapine as monotherapy for FMS will also be assessed. In addition, proof of concept of the indoleamine 2,3-dioxygenase (IDO) activity in FMS will be conducted.

The study will be divided into three parts. In part I, FMS patients of Thai ethnicity will be examined to determine the blood and/or urinary level of anti-nociceptive biogenic amines by comparison with the demographically matched, but unrelated, healthy normal controls (HNC). In part II, the FMS subjects from part I study will be randomized to blinded therapy with mirtazapine or identical appearing placebo. There will be three treatment groups (N=1: 1:1) to accommodate two dosages of mirtazapine (15 mg, 30mg) and placebo given before bedtime. Pill counts at baseline and at follow-up visits will document compliance. Standard outcome instruments (translated and validated in Thai language) will be used at baseline and at each of the follow-up visits. The primary outcome variable will be the changes in the pain visual analog scale (PVAS) score. Secondary clinical outcome variables of interest will include depression, insomnia, anxiety, physical function, morning stiffness, patient global assessment of disease status, patient global impression of change, quality of life and adverse experience. The changes of biogenic amine and IGF-1 concentrations in blood and/or urine with the treatment will be examined as the secondary biochemical measures. In part III, the IDO activity of depressed FMS, non-depressed FMS and HNC will be compared. Moreover, the effect of mirtazapine treatment on the IDO activity in depressed and non-depressed FMS patients will be assessed.

Study hypothesis

1. Anti-nociceptive biogenic amine levels in Thai FMS patients are lower than in Thai healthy normal control.

2. Higher IDO activity could be observed in FMS patients.

3. Mirtazapine is effective in FMS treatment.

Dose Response of Mirtazapine to Methamphetamine Induced Interest, Mood Elevation and Reward [Recruiting]
The primary purpose of this study is to determine if Mirtazapine will produce a decrease in interest in the drug, a decrease in mood elevation, and/or a decrease in reward when given before methamphetamine compared to placebo.

Participants will be screened with a psychiatric interview, medical history and physical, laboratory tests, drug of abuse screen and, if female, a urine pregnancy test. They will be provided written informed consent. They will be studied in a within-subjects examination of the subjective mood responses of mirtazapine and methamphetamine. Interactions between methamphetamine and mirtazapine will be assessed by pharmacokinetic studies. Each participant will be introduced to rating scales and cognitive tasks described below. Participants will remain in the research unit for 5 hours on each day that they receive study medication or placebo. They will spend five days in total on the research unit, one day separated by at least one day; then in two day blocks separated by at least one day from another two day block. A venous catheter will be placed for blood draws. Blood pressures and heart rates will be recorded and assessed. Participants will be randomized and double blinded to receive either placebo or mirtazapine orally two hours prior to the administration of randomized and double blinded methamphetamine or placebo in order to have the peak effects of the drugs overlap. VAS-mood, ARCI, GRS, POMS and POMS-E, neurocognitive tasks Trails A and B and Symbol digits modalities test will be administered prior to the mirtazapine or placebo dose, and repeated after the administration of methamphetamine or placebo. After the administration of methamphetamine or placebo, vital signs will be assessed every 15 minutes and the measures will be repeated until 120 minutes have passed from the initial dose of methamphetamine or placebo. Blood will be drawn at one, three and four hour marks for pharmacokinetic testing. This will be repeated on each testing day.

Combined Mirtazapine and SSRI Treatment of PTSD: A Placebo-Controlled Trial [Recruiting]
The overall goal of this study is to examine the efficacy of the combination of mirtazapine and sertraline in the treatment of posttraumatic stress disorder (PTSD). Sertraline is FDA-approved for PTSD, but it is often not fully effective. The combination of mirtazapine and serotonin reuptake inhibitors like sertraline has appeared highly effective in a related

disorder - - depression.

In this study, sixty patients with chronic PTSD will be randomized to treatment with either sertraline + mirtazapine or sertraline + placebo for 12 weeks. Patients who show at least a minimal response after 12 weeks will continue for another 12 weeks on the same treatment.

Remeron review by 49 year old female patient

Overall rating:  
Effectiveness:   Highly Effective
Side effects:   Mild Side Effects
Treatment Info
Condition / reason:   anxiety, depression, panic attacks
Dosage & duration:   15mg taken one half twice per day for the period of couple of years, still take it
Other conditions:   hypokalemia, panic disorder
Other drugs taken:   Tranxene, K-Tabs
Reported Results
Benefits:   Felt 'normal' rather than in a state of panic and anxiety. Thoughts were clearer and not racing. Felt calm and peaceful.
Side effects:   I was told patients can gain weight on it - i didn't. (apparently you eat more, that's where the extra weight comes from)....can make you tired, which for me is good, as i'm very hyperactive.
Comments:   After trying many anti-depressants, anti-anxiety and panic drugs - sometimes alone, sometimes in combination, nothing really worked for years until i tried (and continue to use) Remeron. It has made a *world* of difference to me and my quality of life. Started out on 7.5 mg one per day - gradually increased it. Too much made me sleepy, but found a right balance. Wish i knew about the drug many many years ago.
