Final answer:
Tricyclics are a type of antidepressant drug used to treat major depression. Examples include Imipramine, Chloripramine, Nortriptyline, Lofepramine, and Amitriptyline.
Step-by-step explanation:
The drugs that are categorized as tricyclics include:
- Imipramine (Tofranil)
- Chloripramine (Anafranil)
- Nortriptyline (Aventyl)
- Lofepramine (Lomont)
- Amitriptyline (Tryptomer)
Tricyclic antidepressants are commonly used for the treatment of major depression. They work by inhibiting the reuptake of certain neurotransmitters, such as serotonin and norepinephrine, in the brain. These drugs can have side effects, so it is important to use them under the supervision of a healthcare professional. However, when administered over a period of time to patients with depression, they can result in an elevated mood and are therefore not prescribed on an "as-needed" basis.
