Antidepressants: which one?

Summary
Tricyclic antidepressants are the first choice for major depression due to proven efficacy and lower cost. Monoamine oxidase inhibitors are a safe alternative, while newer antidepressants offer varied benefits and risks.
Area of Science:
- Pharmacology
- Psychiatry
Background:
- 15 effective antidepressants are available in Canada, including tricyclic antidepressants (TCAs), monoamine oxidase inhibitors (MAOIs), and novel agents.
- TCAs are frequently prescribed for major depression due to their established efficacy, well-documented side effect profiles, and cost-effectiveness.
Purpose of the Study:
- To review the current landscape of antidepressant medications available in Canada.
- To provide guidance on the selection of appropriate antidepressant therapy based on efficacy, safety, and cost.
Main Methods:
- Review of marketed antidepressant medications in Canada.
- Comparative analysis of efficacy, side effect profiles, and cost of different antidepressant classes.
Main Results:
- Tricyclic antidepressants (TCAs) remain the first-line treatment for major depression.
- Monoamine oxidase inhibitors (MAOIs) are a viable and safer alternative than previously thought.
- Maprotiline shows limited advantages over TCAs at a higher cost; trazodone may be a second- or third-line option with fewer anticholinergic effects.
Conclusions:
- Tricyclic antidepressants are recommended as the initial treatment for major depression.
- Monoamine oxidase inhibitors represent a safe and effective alternative treatment option.
- Further evaluation is needed for nomifensine, and amoxapine should be used cautiously due to potential adverse effects.

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...
01:28Drug 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.

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...

01:26Anxiolytic Drugs: Overview
Anxiolytic drugs are vital in managing anxiety disorders by effectively alleviating symptoms such as excessive fear, tachycardia, and tremors. There are several classes of anxiolytic medications, each with unique mechanisms of action and potential side effects.
Primary Types of Anxiolytic Drugs
1. Benzodiazepines:
Benzodiazepines bind to the GABA-A receptor in the brain, enhancing GABA's interaction. This action reduces neurotransmission, effectively blocking anxiety-associated limbic circuitry.
