Antidepressants
Antidepressants are a type of medication used to treat depression and other mental health conditions such as anxiety disorders, post-traumatic stress disorder (PTSD), and obsessive-compulsive disorder (OCD).
Types of Antidepressants
- Selective Serotonin Reuptake Inhibitors (SSRIs): These medications work by increasing the levels of serotonin in the brain. Examples include fluoxetine (Prozac), sertraline (Zoloft), and paroxetine (Paxil).
- Serotonin-Norepinephrine Reuptake Inhibitors (SNRIs): These medications work by increasing the levels of both serotonin and norepinephrine in the brain. Examples include venlafaxine (Effexor) and duloxetine (Cymbalta).
- Tricyclic Antidepressants (TCAs): These medications work by increasing the levels of serotonin and norepinephrine in the brain, but can have more side effects than SSRIs and SNRIs. Examples include amitriptyline (Elavil) and imipramine (Tofranil).
- Monamine Oxidase Inhibitors (MAOIs): These medications work by increasing the levels of serotonin, norepinephrine, and dopamine in the brain. Examples include phenelzine (Nardil) and tranylcypromine (Parnate).
- Atypical Antidepressants: These medications do not fit into any of the other categories and work in different ways to treat depression. Examples include bupropion (Wellbutrin) and mirtazapine (Remeron).
How Antidepressants Work
Antidepressants work by changing the levels of certain chemicals in the brain, such as serotonin, norepinephrine, and dopamine. These chemicals are involved in mood regulation, and changes in their levels can affect a person's mood and behavior.
