Hi Paula-
Thanks for requesting me again! Sorry I'm only now getting to this question - I've had a crazy day!
There are many "new" antipsychotic medications on the market today - they were first introduced in the 1990's and have an increadible impact on the ability of people with psychotic disorders (e.g., schizophrenia, schizophreniform) to function in society has been remarkable.
One such antipsychotic medication is Abilify. Abilify is approved by the FDA to treat schizophrenia and bipolar disorder. The exact reason why Abilify (or any antipsychotic medication) works to treat schizophrenia and bipolar disorder is unknown. Scientists believe, however, that Abilify works by adjusting two different neurtransmitters - dopamine and serotonin. The positive effects associated with Abilify include an almost immediate decrease in the symptoms associated with schizophrenia, including no longer hearing voices, more energy and motivation, clearer/more rational thinking and fewer delusions.
One of the best aspects of the new antipsychotic medications such as Abilify is the decrease in serious side effects associated with the medication. Older antipsychotics had some fairly debilitating side effects (such as tremors), which caused many people who would have benefited from the medication to stop taking it. Abilify, however, has fewer side effects, and side effects that are more manigable. These include: headache (32% of users experienced this), anxiety (25%), insomnia (24%), nausea (14%). Only 9% of takers experienced tremors - a marked decrease from older medications.
Antidepressants work in a similar fashion to antipsychotics, in that they help a neurotransmitter (in this case just serotonin) in the brain function better. One example of an antidepressant is Lexapro. Lexapro is approved by the FDA for the treatment of depression and generalized anxiety disorder. This drug is considered elective serotonin reuptake inhibitors (or SSRI) and works by increasing the output of serotonin. The positive effects of Lexapro in a patient with depression is remarkable: within a week or so, patients feel much less depressed, have more energy and are able to focus better.
Side effects associated with Lexapro are usually well tolerated (especially compared with older antidepressants), and include a decreased libido, difficulties ejaculating, fatigue and tiredness (or "somnolence"). Studies show that only about 4% of users stop taking Lexapro due to side effects (compared to other antidepressants this is statistically significant).
