Final answer:
Antipsychotic drugs are used to suppress symptoms like hallucinations, delusions, and disorganized thinking in schizophrenia but are less effective for emotional instability, which can persist despite medication.
Step-by-step explanation:
Antipsychotic drugs do not effectively relieve schizophrenic people of emotional instability. These medications primarily target symptoms such as hallucinations, delusions, and disorganized thinking, which are associated with overactive dopamine neurotransmission in the brain. By acting as dopamine receptor antagonists, antipsychotics are able to suppress these particular symptoms. However, emotional instability and some negative symptoms, such as a flat affect, loss of pleasure, and lack of motivation, can persist despite medication. This is because the pathophysiology of schizophrenia and emotional regulation is complex and involves more neurotransmitter systems than just dopamine, such as serotonin and glutamate signaling.
