SB-277,011A is used in the study of addiction to stimulant drugs such as nicotine^[4] and cocaine.^[5][6] Where cocaine reduces the threshold for brain electrical self-stimulation in rats, an indication of cocaine's rewarding effects, SB-277,011A completely reverses this effect. It may thus be useful in the treatment of addiction to nicotine and cocaine,^[7][8][9] and is also being investigated for potential uses in the treatment of other drug addictions, such as addiction to heroin^[10] and alcohol.^[11][12][13]

Another potential application for SB-277,011A is in the treatment of schizophrenia,^[14] and it may be particularly useful in treating comorbid patients who are both schizophrenic and addicted to drugs.^[15] However it may worsen side effects such as tardive dyskinesia in patients who are already prescribed antipsychotic drugs.^[16]
