15082129-0	2004	Alfentanil increases cortical dopamine D2/D3 receptor binding in healthy subjects.	Alfentanil	0-10	dopamine receptor D2	Homo sapiens	30-53	
12112410-0	2002	Mu-receptor agonism with alfentanil increases striatal dopamine D2 receptor binding in man.	Alfentanil	25-35	dopamine receptor D2	Homo sapiens	55-75	
12112410-2	2002	We used positron emission tomography (PET) to study the effects of alfentanil (a mu-opioid receptor agonist) on striatal dopamine D2 receptor binding in eight healthy male volunteers.	Alfentanil	67-77	dopamine receptor D2	Homo sapiens	121-141	
12112410-12	2002	These results indicate that pharmacologically relevant concentrations of alfentanil increase D2 dopamine receptor binding in the striatum in man.	Alfentanil	73-83	dopamine receptor D2	Homo sapiens	93-113
