FDA's approval of Iloperidone for schizophrenia....


We did know about the "azepines" for treatment of schizophrenia, but this is a benzisoxazole derivative something interesting. Iloperidone, 1-[4-[3-[4-(6-fluoro-1,2-benzisoxazol-3-yl)-1- piperidinyl]propoxy]-3-methoxyphenyl]ethanone. The advantage, the researcher claims is that, Iloperidone acts on both dopamine and serotonin receptors, making it a favorable choice against competing drugs clozapine and olanzapine. Clinical studies have shown that some patients treated with iloperidone show reduced extrapyramidal symptoms and weight gain. Phase II testing has shown that effectiveness in humans is possible with as low as 8mg per day, and is tolerable up to 32mg per day. The common side effects with this drug are dizziness, dry mouth, fatigue, nasal congestion, sudden fall in blood pressure causing light-headedness upon standing (orthostatic hypotension), drowsiness, rapid heart rate (tachycardia) and weight increase.
