Filter by:The purpose of this study is to conduct experiments to examine subjective and reinforcing effects of nitrous oxide. Mood altering and psychomotor effects will be tested on non-drug abusers and preference procedures will be used to assess reinforcing effects. To examine the lack of acute tolerance development to the subjective, cognitive, and psychomotor effects of nitrous oxide in healthy volunteers.
The purpose of this study is to conduct experiments to examine subjective and reinforcing effects of nitrous oxide. Mood altering and psychomotor effects will be tested on non-drug abusers and preference procedures will be used to assess reinforcing effects. To evaluate the acute and residual effects of subanesthetic concentrations of isoflurane/nitrous oxide combinations in healthy volunteers.
The purpose of this study is to conduct experiments to examine subjective and reinforcing effects of nitrous oxide. Mood altering and psychomotor effects will be tested on non-drug abusers and preference procedures will be used to assess reinforcing effects. To evaluate: cold water immersion modulates the reinforcing effects of nitrous oxide in healthy volunteers.
The purpose of this study is to conduct experiments to examine subjective and reinforcing effects of nitrous oxide. Mood altering and psychomotor effects will be tested on non-drug abusers and preference procedures will be used to assess reinforcing effects. To examine effects of subanesthetic concentrations of nitrous oxide on cold-pressor pain in humans.
The purpose of this study is to evaluate the effects of IV dynorphin in humans during acute heroin abstinence, in order to determine that dynorphin suppresses acute opiate withdrawal, reduces opiate craving, and is safe at doses required to produce the above effects.
The purpose of this study is to test combined buprenorphine and behavioral treatment with and without contingent reinforcement on opioid and cocaine abstinence.
The purpose of this study is to examine if chronic buprenorphine administration will generate supersensitivity to opiates.
The purpose of this study is to assess the degree in which opioid-dependent outpatients discount the value of an additional maintenance dose of buprenorphine under differing states of opioid deprivation.
The purpose of this study is to examine the long-term efficacy of alternate-day dosing schedules in promoting treatment compliance in the absence of confounding behavioral contingencies.
The purpose of this study is to examine the interactions between buprenorphine and naltrexone, and to assess how they may directly impact the clinical issues involving: transferring patients from buprenorphine to naltrexone, developing a non-abusable form of buprenorphine, and enhancing patient acceptability of naltrexone.
