Mirtazapine, sold under the brand name Remeron among others, is an atypical tetracyclic antidepressant, and as such is used primarily to treat depression. Its effects may take up to four weeks but can also manifest as early as one to two weeks. It is often used in cases of depression complicated by anxiety or insomnia. The effectiveness of mirtazapine is comparable to other commonly prescribed antidepressants. It is taken by mouth. Common side effects include sleepiness, dizziness, increased appetite and weight gain. Serious side effects may include mania, low white blood cell count, and increased suicide among children. Withdrawal symptoms may occur with stopping. It is not recommended together with a monoamine oxidase inhibitor, although evidence supporting the danger of this combination has been challenged. It is unclear if use during pregnancy is safe. How it works is not clear, but it may involve blocking certain adrenergic and serotonin receptors. Chemically, it is a tetracyclic antidepressant, and is closely related to mianserin. It also has strong antihistaminergic effects. Mirtazapine came into medical use in the United States in 1996. The patent expired in 2004, and generic versions are available. In 2022, it was the 105th most commonly prescribed medication in the United States, with more than 6 million prescriptions.

Roles Classification
Biological Role(s): alpha-adrenergic antagonist
An agent that binds to but does not activate alpha-adrenergic receptors thereby blocking the actions of endogenous or exogenous alpha-adrenergic agonists. alpha-Adrenergic antagonists are used in the treatment of hypertension, vasospasm, peripheral vascular disease, shock, and pheochromocytoma.
serotonergic antagonist
Drugs that bind to but do not activate serotonin receptors, thereby blocking the actions of serotonin or serotonergic agonists.
histamine antagonist
Histamine antagonists are the drugs that bind to but do not activate histamine receptors, thereby blocking the actions of histamine or histamine agonists.
H1-receptor antagonist
H1-receptor antagonists are the drugs that selectively bind to but do not activate histamine H1 receptors, thereby blocking the actions of endogenous histamine.
Application(s): alpha-adrenergic antagonist
An agent that binds to but does not activate alpha-adrenergic receptors thereby blocking the actions of endogenous or exogenous alpha-adrenergic agonists. alpha-Adrenergic antagonists are used in the treatment of hypertension, vasospasm, peripheral vascular disease, shock, and pheochromocytoma.
serotonergic antagonist
Drugs that bind to but do not activate serotonin receptors, thereby blocking the actions of serotonin or serotonergic agonists.
histamine antagonist
Histamine antagonists are the drugs that bind to but do not activate histamine receptors, thereby blocking the actions of histamine or histamine agonists.
anxiolytic drug
Anxiolytic drugs are agents that alleviate anxiety, tension, and anxiety disorders, promote sedation, and have a calming effect without affecting clarity of consciousness or neurologic conditions.
H1-receptor antagonist
H1-receptor antagonists are the drugs that selectively bind to but do not activate histamine H1 receptors, thereby blocking the actions of endogenous histamine.
oneirogen
Any substance that produces or enhances dream-like states of consciousness.
antidepressant
Antidepressants are mood-stimulating drugs used primarily in the treatment of affective disorders and related conditions.
