Brain receptor

Lthanol (or alcohol) is a two-carbon molecule that, in contrast to many other drugs of abuse, such as opioids, cocaine, and nicotine, does not bind to specific brain receptors. Nonetheless, alcohol affects a variety of neurotransmitter systems, including virtually all of the major systems that have been associated with psychiatric symptoms (Kranzier 1995). Alcohol affects these neurotransmitter systems indirectly by modifying the composition and functioning of... [Pg.1]

Part of the reason may be the relatively crude nature of the tools we have had until recently to study brain function. However, this is clearly beginning to change. Genetic research and functional brain imaging, which actually takes pictures of the brain in action, may ultimately give us a glimpse of brain receptor and enzyme activity that was unthinkable just a few years ago. [Pg.21]

Olanzapine (Zyprexa). The olanzapine molecule is structurally very similar to clozapine and therefore exerts very similar effects on brain receptors. The dose range of olanzapine for treating schizophrenia is from 5 to 30mg/day. Like clozapine, olanzapine appears to treat both positive and negative symptoms. It is also approved for the treatment of the manic phase of bipolar disorder. It has also been shown to augment the antidepressant effects of fluoxetine in refractory patients. [Pg.119]

Interference Therapy. This is conceptually the opposite of the replacement and reward therapies. Whereas replacement medications substitute for the abused drug by stimulating the same brain receptors, interference therapies block these receptors. When the substance abuser uses his/her drug of choice, its effects are blocked by the interference medication. As a result, the drug does not produce the same intensity of pleasurable effects. By reducing the pleasurable effects of drug use, the incentive for repeated use should decrease as well. [Pg.189]

The pharmacotherapy drugs that are the subject of this report fall into one of three general classes (l) brain receptor blockers (2) molecule binders or (3) metabolism modifiers. [Pg.6]

Anandamide inhibited the specific binding of [ H]-HU-243 to synaptosomal membranes in a manner typical of competitive ligands, with an inhibition constant (K ) of 39.0 + 5.0 nM. In this system, the of tsP-THC, a psychoactive compound of cannabis, was 46.0 + 3-0 nM. These were exciting results — the psychoactive compound from a higher plant and a chemically completely different compound in the brain were found to bind to the same brain receptor at about the same level of activity. Soon after the identification of anandamide, this compound was tested for its pharmacological activity. Anandamide administered i.p. in mice, caused... [Pg.61]

Oxytocin receptors are widely distributed in the brain (Insel et al., 1997). Brain receptors are biochemically identical to receptors found in uterine myometrium and mammary myoepithelium. There is a remarkable diversity across species in the neuroanatomical distribution and regulation of OT receptors. These receptors are heavily controlled by gonadal steroids, and the pattern of steroid regulation of OT receptor expression varies across species as well. This diversity of receptors may be the mechanism through which OT function, and thus the social behaviors influenced by that function vary across species. [Pg.199]
