Zoloft
Sertraline
Drug Class and Mechanism of Action of Zoloft
Zoloft belongs to a class of drugs called SSRI (selective serotonin reuptake inhibitors). Other SSRI drugs in this class are Prozac (fluoxetine), Paxil (paroxetine), Celexa (citalopram) and Luvox (fluvoxamine) etc.
Serotonin is a neurotransmitter or a chemical messenger, which is produced by nerve cells in the brain and is used by the nerves to communicate with one another. Serotonin is released into the space surrounding it by a nerve which produces it. This (serotonin) either travels across the space and attaches to receptors on the surface of nearby nerves or it attaches to receptors on the surface of the nerve that produced it, to be taken up by the nerve and released again (a process referred to as re-uptake). Generally there is a balance of serotonin between attachment to the nearby nerves and reuptake. SSRIs (selective serotonin reuptake inhibitors) blocks the reuptake of serotonin and hence change the level (generally increased) of serotonin in the brain.
Some psychiatric illnesses such as depression are caused by disturbances in the balance between serotonin (generally low level in the brain in depression) and other neurotransmitters. The leading theory is that drugs such as Zoloft (sertraline) restore the chemical balance among neurotransmitters in the brain. Zoloft was approved by the FDA in December, 1991.
Therapeutic Uses of Zoloft
Zoloft is commonly used for treatment of psychiatric disorders like depression, obsessive-compulsive disorder (or know as OCD), panic disorder, and posttraumatic stress disorder (also called PTSD) in adults. Zoloft is also approved for use in treatment of OCD in children of 6 to12 years of age and adolescents of 12 to 17 years of age.

This drug must be taken regularly for a few weeks before its full effect is felt and do not stop it after using for few weeks because you are not getting any result.
