Study Notes
Antidepressants: A Comprehensive Overview
- Tricyclic Antidepressants (TCAs) such as imipramine and amitriptyline inhibit SERT and NET, with nine available in the U.S.
- TCAs have adverse side effects including cardiac arrhythmias, hypotension, anti-cholinergic effects, and sedation.
- Fluoxetine (Prozac®), the first selective serotonin reuptake inhibitor (SSRI), was FDA approved for MDD in 1987 and achieved significant commercial success.
- Fluoxetine has been approved for various conditions including OCD, bulimia nervosa, panic disorder, and premenstrual dysphoric disorder.
- Success of fluoxetine led to the development of other SSRIs such as sertraline, paroxetine, and citalopram.
- Side effects of fluoxetine and SSRIs in general include nausea, vomiting, insomnia, sexual dysfunction, anxiety, appetite suppression, and increased risk of suicide (Black Box Warning).
- The FDA's Black Box Warning on antidepressant use in adolescents has led to decreased diagnosis and treatment of childhood depression, decreased use of antidepressants in all age groups, and a decrease in MDD diagnoses.
- Serotonin Syndrome can be induced by drugs increasing serotonin (e.g., SSRIs) and has symptoms such as cognitive, autonomic, and somatic effects, and can be life-threatening.
- Treatment for Serotonin Syndrome is mostly supportive and involves discontinuation of implicated drugs, use of the antagonist cyproheptadine, and dantrolene to control rigidity and fever.
- Trazodone (Desyrel®) was the first of the "2nd generation antidepressants" and has extensive off-label use as a sedative, while Nefazodone (Serzone®) is chemically and pharmacologically related.
- Both Trazodone and Nefazodone produce m-CPP, an active metabolite and serotonergic agonist.
- Other drugs that can induce Serotonin Syndrome include monoamine oxidase inhibitors, sibutramine, tramadol, meperidine, dextromethorphan, amphetamines, and ecstasy.
