DB 5: The Antidepressant Classes, Side by Side
Choosing by Side Effect: How the Antidepressant Classes Differ and Why It Matters for Each Patient
Initial Post
The big picture. Cipriani's network meta-analysis pooled 522 trials and more than 116,000 adults with major depressive disorder; every one of the 21 drugs outperformed placebo, and the gaps between drugs were modest (Cipriani et al., 2018). That means the choice between classes usually rests on side effects, safety, co-occurring conditions and patient preference.
Why SSRIs come first. SSRIs combine good tolerability and safety in overdose. Their main drawbacks are sexual dysfunction, gastrointestinal effects and activation early in treatment (Ferguson, 2001). In the meta-analysis, fluoxetine and agomelatine were the only drugs with fewer dropouts than placebo (Cipriani et al., 2018).
Matching class to patient. For a patient with depression and insomnia, I might consider mirtazapine; for one worried about weight or sexual side effects, bupropion; for depression with fibromyalgia, an SNRI. I avoid tricyclics in patients at risk of suicide because of overdose toxicity.
Across all classes. Every antidepressant carries a boxed warning for suicidal thinking in people under 25, so close follow-up in the first weeks matters (Stahl, 2021).
| Class | How it works | Common side effects | Safety concerns | Often chosen when |
|---|---|---|---|---|
| SSRIs | Block serotonin reuptake | Nausea, sexual dysfunction, sleep changes | Bleeding risk with anticoagulants, hyponatremia in older adults | First line for depression and most anxiety disorders |
| SNRIs | Block serotonin and norepinephrine reuptake | As SSRIs plus sweating, raised blood pressure | Discontinuation symptoms | Depression with chronic pain |
| Bupropion | Blocks norepinephrine and dopamine reuptake | Insomnia, dry mouth | Lowers seizure threshold | Concern about sexual side effects or weight gain; smoking cessation |
| Mirtazapine | Blocks alpha-2 and several serotonin receptors | Sedation, appetite and weight gain | Weight and metabolic effects | Insomnia or poor appetite |
| Serotonin modulators (trazodone, vilazodone, vortioxetine) | Mixed reuptake blocking and receptor effects | Sedation (trazodone), nausea | Priapism (trazodone, rare) | Insomnia; SSRI side effects |
| Tricyclics | Block reuptake plus many other receptors | Dry mouth, constipation, dizziness | Cardiac conduction effects, lethal in overdose | Treatment resistance, pain, migraine prevention |
| MAOIs | Block monoamine oxidase | Dizziness, insomnia | Hypertensive crisis with tyramine, serotonin syndrome with interacting drugs | Treatment-resistant or atypical depression |
Reply to a Classmate (Sexual Side Effects)
You asked how to handle SSRI sexual side effects. Options include waiting a few weeks, switching to bupropion or mirtazapine, or adding bupropion, chosen with the patient's priorities in mind.

Reading the DNP 672 Module 3 assignment instructions
In the depression week, the posted syllabus assigns chapters in the course psychopharmacology texts and sets discussion board 5: describe the differences between the classes of antidepressants. Posts are graded weekly with the same rubric as the other boards, which rewards timely posts that cite current evidence and replies that advance the discussion. Expect to cover the main classes, how each works, typical side effects, key safety concerns and situations in which each is a good choice. A table can help classmates compare classes quickly, but explain the reasoning in text as well. Because many classmates will cover the same classes, practical judgment about matching a class to a patient helps a post stand out.
Inside the DNP 672 Module 3 example
The post opens with a network meta-analysis showing modest differences in efficacy, which sets up the point that side effects and safety drive the choice. A table then compares seven classes across mechanism, common side effects, safety concerns and typical uses. Paragraphs below explain why SSRIs come first, give three examples of matching a class to a patient and note the boxed warning that applies to all classes. A brief reply addresses sexual side effects. It rests on a network meta-analysis, a review of SSRI tolerability and the course text. No doses appear, and drug names are used only to illustrate a class. Three short patient examples show how the table becomes a prescribing decision, and the boxed warning paragraph applies to every class.
Reading the DNP 672 Module 3 grading rubric
Faculty are likely to look for accurate mechanisms, correct side effect and safety profiles for each class, current evidence on comparative efficacy, practical reasoning about matching drugs to patients, mention of class-wide warnings and engagement with classmates. The stronger posts explain why the differences matter clinically rather than listing features. A table is useful if the text interprets it. Citing a large comparative analysis shows awareness of the evidence base. Replies that answer common practice questions, such as handling sexual side effects, add value to the discussion. Faculty may also check that the post separates efficacy differences, which are small, from tolerability differences, which often decide the choice.
DNP 672 Module 3 help: mistakes that cost marks
A typical weakness is a long list of drugs within each class. Focus on what distinguishes the classes. Another is omitting serious safety issues, such as MAOI interactions or tricyclic overdose risk. Check each side effect against a reliable source. If you want help building a comparison table for your own post, tell the desk which classes your faculty emphasized. Keep doses out unless asked. Use patient examples from your practicum in your reply. When you build a table, keep every row to the same columns so classmates can scan across classes, and explain at least one row in the text below it.

Scroll up for a full DNP 672 board 5 sample comparing seven antidepressant classes in a table, with evidence and a reply.
Are some antidepressants much more effective than others?
Not by much: in a pooled analysis of 522 trials, every one of 21 drugs outperformed placebo, and the gaps between them were modest.
Why are SSRIs usually first line for depression?
They combine good tolerability with relative safety in overdose, though sexual and gastrointestinal side effects are common.
Which antidepressant has fewer sexual side effects?
Bupropion and mirtazapine are less likely than SSRIs to cause sexual dysfunction.
What warning applies to all antidepressants?
Every antidepressant's label has a boxed warning on suicidality in patients younger than 25, which is why the first weeks need close follow-up.
