Final answer:
The anti-psychotic drug haloperidol targets dopamine D2 receptors in the brain. Option B is correct.
Step-by-step explanation:
The anti-psychotic drug haloperidol is particularly selective for dopamine D2 receptors. This means that haloperidol primarily targets and interacts with the D2 subtype of dopamine receptors in the brain.
The selectivity of haloperidol for D2 receptors is based on its chemical structure and affinity for this specific receptor subtype. By binding to D2 receptors, haloperidol can modulate dopamine activity and help alleviate symptoms associated with psychosis and other psychiatric conditions.
It's important to note that haloperidol may also interact with other dopamine receptor subtypes to varying degrees, but its selectivity for D2 receptors is particularly prominent.
The antipsychotic drug haloperidol is particularly selective for dopamine D2 receptors. When it comes to psychotic disorders such as schizophrenia, one evident characteristic is the dysregulation of dopamine neurotransmission, primarily within the mesolimbic pathway.
As a medication, haloperidol works by antagonizing these D2 receptors, thus reducing dopaminergic activity, which can help alleviate symptoms like delusions and hallucinations.
It's essential to monitor for side effects associated with movement disorders, as the D2 receptors are also present in the extrapyramidal system. Such movement disorders can resemble those that arise from issues within the basal nuclei, a group of nuclei in the brain associated with movement regulation.
