Treating Depression with Amitriptyline Antidepressants
Amitriptyline belongs to the group of drugs tricyclic antidepressants (TCAs) and is mainly used to manage depression. It can also help treat bipolar disorder, insomnia, and chronic pain.
The newer antidepressants are more commonly used as they have fewer side effects, but TCAs still play a significant role in managing these disorders. They are named so as the molecule consists of three rings of atoms.
It is a prescription medicine and available as a liquid and tablets.
Let’s understand more about Amitriptyline, how it can help treat depression, and its use, dosage, precautions, interactions, and side effects.

Amitriptyline and Treating Depression
Depression is caused by a chemical imbalance that results in abnormal communications between nerve cells in the brain. The chemical delivering these messages are known as neurotransmitters.
The neurotransmitters pass a message from one cell to the other. How you feel and react to the message depends on the type of neurotransmitter.
When the brain cells pass signals to one another, they also release the chemicals to deliver the message. They have to take back the chemical so that they can pass the next message. This process of taking the chemical back is known as “reuptake.”
Amitriptyline prevents the reabsorption of neurotransmitters serotonin and norepinephrine. Serotonin mainly regulates your mood, and norepinephrine aids in the fight-or-flight reaction.
By preventing reuptake, Amitriptyline increases the levels of these chemicals, improving the symptoms of depression.
Along with depression, Amitriptyline can also help manage the following conditions:
- Chronic pain
- Post-traumatic stress disorder
- Excessive saliva production
- Irritable bowel syndrome
- Shingle’s pain
- Interstitial cystitis
