Amitriptyline is a tricyclic depressant used to treat many behavioral disorders in pets. It may be prescribed to treat separation anxiety, excessive grooming, death of a companion, or other problems. Amitriptyline has a pain relieving component, and is often used for anxiety disorders involving pain in cats.
How It Works
Serotonin and norepinephrine are chemicals in the brain that reverse the feelings of depression. They are released into the brain and then reabsorbed into the brain where they are no longer effective. Amitriptyline works preventing the reabsorption of these neurotransmitters back into nerve cells in the brain. This increases the levels of these chemicals and allows them to stick around the brain longer.
Store in a tightly sealed container at room temperature.
