  • Title: Chronic prenatal haloperidol exposure: lack of effect on presynaptic dopamine autoreceptors.
    Author: Scalzo FM, Newport GD, Gough BJ, Ali SF, Holson RR.
    Journal: Neurotoxicology; 1989; 10(3):485-90. PubMed ID: 2516618.
    Abstract:
    Prenatal haloperidol exposure in rats is known to reduce striatal D2 receptor binding in postnatal day (PND) 30 offspring. The effects of prenatal haloperidol exposure on presynaptic dopamine (DA) autoreceptor function are not well described. Pregnant albino rats were given daily injections of haloperidol (2.5 or 5.0 mg/kg, sc) or vehicle over gestational days 6-20. Presynaptic DA autoreceptor function was assessed using the DOPA decarboxylase inhibitor NSD-1015 and gamma-butyrolactone in the caudate, nucleus accumbens and olfactory tubercles of male offspring sacrificed on PND 97. There appeared to be no impairment of autoreceptor function in any region studied. The data indicate that prenatal haloperidol exposure does not result in permanent alterations in presynaptic DA autoreceptor function.
