Summary
Mirtazapine shows faster efficacy than SSRIs for major depression treatment. While dropouts are similar across antidepressants, mirtazapine has a unique side effect profile, including weight gain and somnolence.
Area of Science:
- Pharmacology
- Clinical Psychiatry
- Evidence-Based Medicine
Background:
- Mirtazapine is a widely used antidepressant with a distinct mechanism of action.
- Major depression treatment requires effective and well-tolerated antidepressant agents.
Purpose of the Study:
- To evaluate the efficacy and acceptability of mirtazapine compared to other antidepressants.
- To assess mirtazapine's effectiveness in the acute phase of major depression in adults.
Main Methods:
- Systematic review and meta-analysis of randomized controlled trials (RCTs).
- Searched multiple databases (Cochrane, EMBASE, MEDLINE, PsycINFO) up to July 2011.
- Included 29 RCTs (4974 participants) comparing mirtazapine with other antidepressants.
Main Results:
- Mirtazapine demonstrated significantly higher efficacy than SSRIs at two weeks and end of acute treatment.
- Mirtazapine was more effective than venlafaxine (a noradrenaline reuptake inhibitor) in the acute phase.
- No significant difference in dropout rates was found, but mirtazapine was associated with more weight gain and somnolence than SSRIs.
Conclusions:
- Mirtazapine exhibits a faster onset of action compared to SSRIs in acute major depression treatment.
- While overall dropout rates are comparable, mirtazapine's unique adverse event profile requires consideration.
- Statistically significant and potentially clinically meaningful differences exist between mirtazapine and other antidepressants.

01:23Antidepressant Drugs: MAOIs and Other Agents
Atypical antidepressants, including bupropion (Wellbutrin), mirtazapine (Remeron), nefazodone (Serzone), trazodone (Desyrel), and vilazodone (Viibryd), offer unique mechanisms of action. Bupropion weakly inhibits dopamine and norepinephrine reuptake, aiding depression treatment and smoking cessation, with a low risk of sexual dysfunction. Mirtazapine enhances serotonin and norepinephrine neurotransmission, leading to sedation, increased appetite, and weight gain. As a result, it helps treat...
01:28Antidepressant Drugs: Tricyclics, SSRIs, and SNRIs
Tricyclic Antidepressants (TCAs), including Desipramine (Norpramin), Imipramine (Tofranil), Clomipramine (Anafranil), and Amitriptyline (Elavil), inhibit serotonin and norepinephrine reuptake and also block other receptors. They are used for depression, pain conditions, and insomnia. Common adverse effects include anticholinergic effects, sedation, orthostatic hypotension, and weight gain. They have a narrow therapeutic window and so require plasma-level monitoring. Abrupt discontinuation can...
01:25Antidepressant Drugs: Overview
Antidepressant drugs are a class of medications primarily used for treating various mood disorders, including major depression, anxiety disorders, and other related conditions. These medicines work by modulating the neurotransmitter balance within the brain, alleviating depressive symptoms. Antidepressants can be broadly categorized into several groups according to their mechanism of action and chemical structure: Selective Serotonin Reuptake Inhibitors (SSRIs), Serotonin-Norepinephrine...
01:17Sedatives and Hypnotics Drugs: Miscellaneous Agents
Sedatives and hypnotics encompass a wide range of substances, each with its unique mechanism of action, uses, and potential adverse effects.
Melatonin congeners like ramelteon (Rozerem) and tasimelteon (Hetlioz) selectively bind to melatonin receptors (MT1 and MT2) and thus mimic the actions of melatonin, a hormone that regulates sleep-wake cycles. Tasimelteon is primarily used for non-24-hour sleep-wake disorder, common in blind patients. They are also used to treat conditions like insomnia...

01:26Psychosis: Goals of Pharmacotherapy
Antipsychotic drugs are a crucial treatment method for acute and chronic psychoses, bipolar illness, and behavioral disorders. The selection of these drugs depends on several factors, including the state of the disease, clinical judgment, possible drug interactions, and the patient's sensitivity to adverse effects. In immediate scenarios, such as delirium and dementia, short-term treatment with low doses of high-potency typical or atypical agents can effectively manage symptom exacerbation. For...
01:28Drug Therapy
The advent of drug therapy has profoundly shaped modern mental health care, providing targeted treatments for a range of psychological disorders. Psychotherapeutic drugs, classified into antianxiety, antidepressant, and antipsychotic medications, address symptoms across anxiety disorders, mood disorders, and schizophrenia. While these medications have transformed patient outcomes, they require careful management due to their potential side effects and limitations.
