Comprehensive All Antidepressants List by Primary Family

Quick Answer

Antidepressants are grouped into several primary medication families based on how they affect brain chemicals such as serotonin, norepinephrine, and dopamine. Selective Serotonin Reuptake Inhibitors (SSRIs) are usually the first-line treatment for depression because they balance effectiveness and safety. Other families, including SNRIs, atypical antidepressants, tricyclic antidepressants (TCAs), monoamine oxidase inhibitors (MAOIs), serotonin modulators, NMDA receptor antagonists, and newer combination therapies, may be recommended depending on symptoms, medical history, side effects, and previous treatment response.

Table of Contents

Antidepressant Family	Primary Mechanism	Common Examples	Typical Uses
SSRIs	Increase serotonin	Sertraline, Fluoxetine, Escitalopram, Paroxetine, Citalopram, Fluvoxamine	Major depression, anxiety disorders, OCD, PTSD
SNRIs	Increase serotonin and norepinephrine	Venlafaxine, Desvenlafaxine, Duloxetine, Levomilnacipran, Milnacipran	Depression, anxiety, chronic pain
NDRIs	Increase norepinephrine and dopamine	Bupropion	Depression, seasonal affective disorder, smoking cessation
NaSSA	Increase norepinephrine and serotonin indirectly	Mirtazapine	Depression with insomnia or poor appetite
Serotonin Modulators	Affect serotonin receptors and reuptake	Trazodone, Nefazodone, Vilazodone, Vortioxetine	Depression, sleep problems
TCAs	Block serotonin and norepinephrine reuptake	Amitriptyline, Nortriptyline, Imipramine, Clomipramine, Desipramine, Doxepin	Depression, chronic pain, migraine prevention
MAOIs	Block monoamine oxidase enzyme	Phenelzine, Tranylcypromine, Isocarboxazid, Selegiline Patch	Treatment-resistant depression
NMDA Antagonists	Enhance glutamate signaling	Esketamine	Treatment-resistant depression

Why Antidepressants Are Classified Into Families

Grouping antidepressants into medication families helps healthcare professionals predict:

How each medication works
Expected benefits
Common side effects
Drug interactions
Appropriate patient selection

Although medications within the same family share similar mechanisms, each drug has unique characteristics.

Selective Serotonin Reuptake Inhibitors (SSRIs)

SSRIs remain the most commonly prescribed antidepressants worldwide.

Common SSRIs

Sertraline (Zoloft)
Fluoxetine (Prozac)
Escitalopram (Lexapro)
Citalopram (Celexa)
Paroxetine (Paxil)
Fluvoxamine (Luvox)

Advantages

Good safety profile
Effective for anxiety disorders
Lower overdose risk
Well studied

Possible Side Effects

Nausea
Headache
Sexual dysfunction
Sleep changes
Temporary increase in anxiety during early treatment

Serotonin-Norepinephrine Reuptake Inhibitors (SNRIs)

SNRIs increase both serotonin and norepinephrine.

Common SNRIs

Venlafaxine
Desvenlafaxine
Duloxetine
Levomilnacipran
Milnacipran (primarily approved for fibromyalgia in some countries)

Benefits

They may be particularly useful for patients with:

Depression
Generalized anxiety disorder
Diabetic neuropathy
Fibromyalgia
Chronic musculoskeletal pain

Norepinephrine-Dopamine Reuptake Inhibitors (NDRIs)

Main Medication

Bupropion (Wellbutrin)

Unique Benefits

Minimal sexual side effects
May improve energy
Can support smoking cessation
Less likely to cause weight gain

Possible Drawbacks

May increase anxiety in some people
Not suitable for individuals with seizure disorders

Noradrenergic and Specific Serotonergic Antidepressants (NaSSA)

Main Medication

Mirtazapine (Remeron)

Advantages

Improves sleep
May increase appetite
Helpful for weight loss related to depression

Common Side Effects

Drowsiness
Weight gain
Increased appetite

Serotonin Modulators and Stimulators

These medications work differently from traditional SSRIs.

Common Medications

Trazodone
Vilazodone
Vortioxetine
Nefazodone

Potential Benefits

Improved cognitive symptoms
Better sleep (especially trazodone)
Lower rates of certain SSRI side effects in some patients

Tricyclic Antidepressants (TCAs)

TCAs were among the earliest antidepressants developed.

Common TCAs

Amitriptyline
Nortriptyline
Imipramine
Clomipramine
Desipramine
Doxepin

Clinical Uses

Besides depression, TCAs are prescribed for:

Neuropathic pain
Migraine prevention
Insomnia
OCD (Clomipramine)

Limitations

Dry mouth
Constipation
Dizziness
Cardiac effects
Greater overdose risk

Monoamine Oxidase Inhibitors (MAOIs)

Although used less often today, MAOIs remain valuable for some individuals with treatment-resistant depression.

Available MAOIs

Phenelzine
Tranylcypromine
Isocarboxazid
Selegiline Transdermal Patch

Important Considerations

Patients must follow dietary restrictions because certain foods high in tyramine can cause dangerous increases in blood pressure.

NMDA Receptor Antagonists

This newer class targets glutamate instead of monoamines.

Medication

Esketamine Nasal Spray

Approved Use

Treatment-resistant depression
Depression with acute suicidal symptoms (under supervised care in some settings)

Administration occurs only in certified healthcare facilities because monitoring is required.

Newer Combination Therapies

Some recently approved medications combine multiple mechanisms.

Examples include:

Dextromethorphan-Bupropion
Fixed-dose combinations approved in selected countries

These medications may work faster for some patients, although long-term research continues.

Comparing the Main Antidepressant Families

Family	First-Line	Anxiety	Sleep	Weight Gain	Sexual Side Effects
SSRIs	Yes	Excellent	Neutral	Low	Common
SNRIs	Yes	Excellent	Neutral	Low	Common
NDRI	Sometimes	Moderate	May increase alertness	Low	Rare
NaSSA	Sometimes	Good	Excellent	Higher	Less common
TCAs	No	Good	Good	Moderate	Moderate
MAOIs	No	Good	Variable	Variable	Variable
NMDA Antagonists	Specialized	Limited	Neutral	Minimal	Minimal

How Doctors Choose an Antidepressant

Several factors influence medication selection:

Previous response
Family history of medication success
Anxiety symptoms
Sleep quality
Appetite changes
Chronic pain
Other medical conditions
Current medications
Pregnancy or breastfeeding considerations
Potential drug interactions

There is no single antidepressant that is best for everyone.

Safety Considerations

Antidepressants should always be used under medical supervision.

Patients should:

Take medications exactly as prescribed.
Avoid stopping suddenly without guidance.
Report unusual mood changes immediately.
Attend regular follow-up appointments.
Inform healthcare providers about all other medications and supplements.

Frequently Asked Questions

What is the most commonly prescribed antidepressant family?

SSRIs are generally the most commonly prescribed first-line antidepressants because they offer a favorable balance of effectiveness, safety, and tolerability.

Which antidepressants usually cause the fewest sexual side effects?

Bupropion is commonly associated with a lower risk of sexual side effects compared with many SSRIs and SNRIs, though individual responses vary.

Are older antidepressants still prescribed?

Yes. TCAs and MAOIs are still used for certain patients, particularly when newer medications have not been effective or when specific symptoms make them appropriate.

How long do antidepressants take to work?

Many people begin noticing improvement within 2 to 4 weeks, but the full therapeutic effect often takes 6 to 8 weeks or longer.

Can antidepressants be stopped suddenly?

No. Many antidepressants should be tapered gradually under medical supervision to reduce the risk of withdrawal symptoms and relapse.
