DRUG CLASS AND MECHANISM: Fluoxetine is an oral drug that is used primarily for treating depression. It is in a class of drugs called selective serotonin reuptake inhibitors (SSRIs), a class that includes citalopram (Celexa), paroxetine (Paxil) and sertraline (Zoloft). Fluoxetine affects neurotransmitters, the chemicals that nerves within the brain use to communicate with each other. Neurotransmitters are manufactured and released by nerves and then travel and attach to nearby nerves. Thus, neurotransmitters can be thought of as the communication system of the brain. Serotonin is one neurotransmitter that is released by nerves in the brain. The serotonin either travels across the space between nerves 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). Many experts believe that an imbalance among neurotransmitters is the cause of depression. Fluoxetine works by preventing the reuptake of one neurotransmitter, serotonin, by nerve cells after it has been released. Since uptake is an important mechanism for removing released neurotransmitters and terminating their actions on adjacent nerves, the reduced uptake caused by fluoxetine increases free serotonin that stimulates nerve cells in the brain. The FDA approved Fluoxetine in December 1987.
