Antipsychotic drugs were introduced in the early 50s on the basis of clinical observations in patients with schizophrenia. Experimental studies later revealed that antagonism at the D(2) dopamine receptor is a common characteristic of all antipsychotic drugs. In the 80s, the advent of brain imaging technologies such as positron emission tomography (PET)(More)
Quetiapine is an established drug for treatment of schizophrenia, bipolar disorder, and major depressive disorder. While initially manufactured as an immediate-release (IR) formulation, an extended-release (XR) formulation has recently been introduced. Pharmacokinetic studies show that quetiapine XR provides a lower peak and more stable plasma concentration(More)
PURPOSE Age-related changes in the serotonin system have been described, and proposed to be associated with behavioral changes observed particularly in the elderly population. The 5-HT1B receptor is thought to have a regulatory role in a number of physiological functions, and has been implicated in several age-related diseases. The purpose of the present(More)
Selective serotonin reuptake inhibitors (SSRIs) are widely prescribed for treatment of psychiatric disorders. The exact mechanism underlying the clinical effects of SSRIs remains unclear, although increased synaptic serotonin concentrations have been hypothesized to be an initial step. [¹¹C]AZ10419369 is a novel 5-HT(1B) receptor selective radioligand,(More)
[11C]AZ10419369 is a recently developed 5-HT1B receptor radioligand that is sensitive to changes in endogenous serotonin concentrations in the primate brain. Thus, [11C] AZ10419369 may serve as a useful tool in clinical studies of the pathophysiology and pharmacological treatment of diseases related to the serotonin system, such as depression and anxiety(More)
AIM To investigate the occupancy at brain 5-hydroxytryptamine (5-HT) 1B receptors in human subjects after administration of the antimigraine drug zolmitriptan. METHODS Positron emission tomography (PET) studies were undertaken using the radioligand [(11)C]AZ10419369 in eight control subjects at baseline and after administration of zolmitriptan(More)
[(11) C]AZ10419369 is sensitive to pharmacologically enhanced endogenous serotonin levels. Twelve healthy volunteers underwent [(11) C]AZ10419369 PET and lumbar puncture. There were no correlations between [(11) C]AZ10419369 binding and concentrations of serotonin and its metabolite 5-HIAA in cerebrospinal fluid, suggesting that [(11) C]AZ10419369 brain(More)
