Paroxetina, otherwise known as Paxil, is a type of antidepressant drug used to treat a variety of conditions such as major depressive disorder, panic disorder, obsessive–compulsive disorder, and post-traumatic stress disorder, premenstrual dysphoric disorder, and social anxiety disorder. Paroxetina works by increasing levels of dopamine, serotonin, and norepinephrine in the brain to help regulate mood and balance other neurotransmitters in the brain important for mental health.

Uses For Paroxetina
