The effect of prenatal exposure to methadone via maternal osmotic minipumps was studied on neurotransmitter content of 4-day-old male and female rats. Several sex-related differences were observed in brain regional neurotransmitter content. Prenatal exposure to methadone produced only selective changes in brain regional neurotransmitter content. Exposure to methadone in doses sufficient to produce maternal and fetal dependence selectively reduced striatal acetylcholine content and produced a sex-dependent change in hindbrain acetylcholine.

Drugs Affecting Neurotransmitter Synthesis

Drugs affecting neurotransmitter synthesis can impact the adrenergic neuron and the synthesis of neurotransmitters. For example, α-methyltyrosine and carbidopa target specific enzymes involved in catecholamine synthesis. α-methyltyrosine inhibits the enzyme tyrosine hydroxylase, which converts tyrosine into dopamine. By blocking this enzyme, α-methyltyrosine reduces dopamine production and other catecholamines. Carbidopa, on the other hand, inhibits the enzyme dopa decarboxylase, which converts...
