Certainly antidepressants, like the serotonin reuptake inhibitors (Prozac and others) have proved very helpful in treating anxiety; some doctors think they are even more effective against anxiety than they are against depression. Although no one knows exactly why these antidepressants work, one important clue is that their effects don't show up until after a few weeks of treatment. The pathways for toning down anxiety are apparently much more resistant than those for ratcheting...
ANTIDEPRESSANTS When talk therapy doesn't work--or needs a boost--drugs can help, especially the class of antidepressants called selective serotonin reuptake inhibitors. Prozac is the best known of these drugs, which work by preventing the brain from reabsorbing too much of the neurotransmitter serotonin, leaving more in nerve synapses and thus helping to improve mood. Another SSRI, Paxil, was recently approved by the Food and Drug Administration specifically for the treatment of social-anxiety disorder, though the others seem to work as well. A third, Zoloft, has been approved for OCD and panic disorder. Each formulation of SSRI...
...contribute to susceptibility to autism? Present estimates run from as few as three to more than 20. Coming under intensifying scrutiny, as the papers published by Molecular Psychiatry indicate, are genes that regulate the action of three powerful neurotransmitters: glutamate, which is intimately involved in learning and memory, and serotonin and gamma-aminobutiric acid (GABA), which have been implicated in obsessive-compulsive behavior, anxiety and depression...
...there were many—the potential of the popular drug Prozac as an anti-depressant. But, to put it mildly, there is no consensus among psychiatrists—or, for that matter, anyone else—on the efficacy, safety, or propriety of Prozac and other Selective Serotonin Reuptake Inhibitors (SSRI’s) as medication for various forms of depression...
...SSRIs. Their advantage over the earlier generation of tricyclic antidepressants, we were taught, is not that they are so much more effective but that they are a lot more selective and easier to use. Unlike the tricyclics, which interfered with neurotransmitters throughout the brain, the SSRIs zero in on serotonin, the master molecule of mood--lifting depression with fewer side effects and less risk of overdose...
