Newest Medication For Depression
Q: Paxil (paroxetine hydrochloride), a new antidepressant medication,was
introduced into the United States in early 1993. It is a member of the
SSRI (selective serotonin reuptake inhibitor) family(along with Zoloft

symptoms of major depression without causing some of the harmful
side effects caused by the oldertricyclic antidepressants (TCAs).
A:What does Paxil treat?

genetic factors may contribute to the illness. Depression is
associated with a decreased number of neurotransmitters in the
brain (particularly serotonin and norepinephrine). These chemical
messengers help regulate several functions and thoughts, including
mood. Paxil blocks the reabsorption of serotonin and normalizes the
brain's chemical supply.

Paxil is as effective in relieving depression as TCAs such as
imipramine. However, Paxil causes fewer adverse cardiovascular
and anticholinergic effects (dry mouth, constipation, blurred vision,
urinary retention) than the older TCAs. It does not usually cause
