What Is Paroxetine Mesylate Used For?

Using Paroxetine Mesylate for Generalized Anxiety Disorder

Generalized anxiety disorder (GAD) is much more than the normal worrying or anxiety people may experience on occasion. It is a chronic, excessive worrying, even when there is little or nothing to worry about. People with GAD often worry excessively about health, money, family, work, or many other things. These excessive worries may make it hard to function or to get through the day.
Several different treatments are available for generalized anxiety disorder, including cognitive behavioral therapy and various different types of medications. Paroxetine mesylate is just one of many medications approved to treat generalized anxiety disorder. Like similar medications used to treat GAD, paroxetine mesylate may take several weeks to start working.

How Does Paroxetine Mesylate Work?

Paroxetine mesylate belongs to a class of drugs called selective serotonin reuptake inhibitors (SSRIs). Like other SSRIs, paroxetine mesylate works on serotonin, a chemical found in the body. Serotonin is thought to affect mood and behavior.
As a message travels down a nerve, it causes the end of the cell to release serotonin. The serotonin enters the space between the first nerve cell and the one next to it. When enough serotonin reaches the second nerve cell, it activates receptors on the cell and the message continues on its way. The first cell then quickly absorbs any serotonin that remains in the gap between cells; this is called "reuptake."
Normally, this process works without any problems. But when the levels of serotonin become unbalanced, it can cause a variety of conditions, including depression. Paroxetine mesylate helps to block the reuptake of serotonin so more remains in the space between the brain's nerve cells. This gives the serotonin a better chance of activating the receptors on the next nerve cell.
