Antidepressant Drugs: Tricyclics, SSRIs, and SNRIs

Antidepressant 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...

Antidepressant Drugs: MAOIs and Other Agents

Antidepressant 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...

Drug Dosing: Geriatric Patients

Drug Dosing: Geriatric Patients

Elderly individuals encompass a diverse population with varying degrees of age-related physiological changes. Defining the elderly presents challenges, as the geriatric population is often arbitrarily categorized as individuals older than 65. However, many individuals in this group lead active and healthy lives, with an increasing number surpassing 85 years and falling into the older elderly category. Physiological changes associated with aging impact performance capacity and homeostatic...

Antidepressant Drugs: Overview

Antidepressant 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...

Pharmacodynamics in Geriatric Patients: Effects of Age

Pharmacodynamics in Geriatric Patients: Effects of Age

Age-related pharmacokinetic changes are extensively documented, but understanding age-related pharmacodynamic alterations is relatively limited. This knowledge gap can be partly attributed to the complexity of developing appropriate measures of drug responses compared to bioanalytical methods for determining drug concentrations.Most information regarding age-related differences in human pharmacodynamics originates from cross-sectional studies. However, these studies assume that observed mean...

Depressants

Depressants

Depressant drugs, including alcohol and sedative-hypnotics, diminish central nervous system activity by enhancing the action of gamma-aminobutyric acid (GABA), a neurotransmitter that reduces brain activity and promotes relaxation. These substances can have various therapeutic uses but also pose significant risks, especially when misused or combined.
Alcohol is a common depressant that can induce a sense of relaxation and reduced inhibition at low doses. Contrary to its occasional...

Summary

Antidepressants are linked to falls, with side effects like drowsiness and orthostatic hypotension contributing. The risk of falling with antidepressants is similar to that of untreated depression.

Area of Science:

Pharmacology
Geriatrics
Neurology

Background:

Antidepressants are frequently associated with an increased risk of falls in patients.
Data are extensive for tricyclic antidepressants (TCAs) and selective serotonin reuptake inhibitors (SSRIs), but limited for other classes.
Potential contributing factors include sedation, sleep disturbances, orthostatic hypotension, and cardiac issues.

Purpose of the Study:

To review the association between various antidepressant classes and falls.
To elucidate the mechanisms by which antidepressants may increase fall risk.

Main Methods:

Literature review of studies examining antidepressants and falls.
Analysis of postulated mechanisms linking antidepressant side effects to falls.

Network Pharmacology and Validation of the Antidepressant Mechanisms of Qiangzhifang in a Chronic Restraint Stress-induced Depression Rat Model

Published on: June 6, 2025

Main Results:

Sedation, insomnia, orthostatic hypotension, and cardiac rhythm disturbances are common side effects linked to falls.
Both TCAs and SSRIs can cause daytime drowsiness, a significant fall risk factor.
The increased fall risk associated with antidepressants is comparable to that of untreated depression.

Conclusions:

Insufficient data exist to clear any specific antidepressant or class from causing falls.
Antidepressant-induced side effects, particularly those affecting balance and cognition, contribute to fall risk.
Further research is needed to fully assess the contribution of specific antidepressant-induced mechanisms to falls.
