BACKGROUND Combining drugs not only reduces specific adverse effects of each of the drug at a higher dose but also may lead to enhanced efficacy. Tapentadol is a recently discovered analgesic possessing μ-opioid receptor agonism and noradrenaline re-uptake inhibition in a single molecule. Taking

Using neurochemical method, evidence was obtained that cannabinoid CB(1) receptors are localized on noradrenergic terminals and their stimulation by WIN-55,212-2 reduces the release of [3H]noradrenaline evoked by axonal activity in a frequency-dependent manner. At stimulation rates of 1 and 3 Hz,

We examined the question of whether cannabinoid receptors modulating noradrenaline release are detectable in the brain of humans and experimental animals. For this purpose, hippocampal slices from humans, guinea-pigs, rats and mice and cerebellar, cerebrocortical and hypothalamic slices from

Cannabinoids exert complex effects on blood pressure related to their interference with cardiovascular centres in the central nervous system and to their direct influence on vascular muscle, vascular endothelium and heart. In view of the relative lack of information on the occurrence of CB1

Guinea-pig hippocampal slices preincubated with [3H]noradrenaline were superfused with medium containing desipramine and rauwolscine and rat striatal slices preincubated with [3H]dopamine were superfused with medium containing nomifensine; the effect of cannabinoid receptor ligands on tritium

Release-modulating opioid and cannabinoid (CB) receptors, beta-adrenoceptors and bradykinin receptors at noradrenergic axons were studied in mouse tissues (occipito-parietal cortex, heart atria, vas deferens and spleen) preincubated with (3)H-noradrenaline. Experiments using the OP(1)

1. Activation of CB1 receptors by plant cannabinoids or the endogenous ligand, anandamide, causes hypotension via a sympathoinhibitory action in anaesthetized rats. In mouse isolated vas deferens, activation of CB1 receptors inhibits the electrically evoked twitch response. To determine if these

The nonpsychoactive plant cannabinoid, (-)-cannabidiol, modulates in vivo responses to Delta(9)-tetrahydrocannabinol. We have found that cannabidiol can also interact with cannabinoid CB(1) receptor agonists in the mouse vas deferens, a tissue in which prejunctional cannabinoid CB(1) receptors

Our objective was to identify the sites of interaction of cannabinoids with cardiovascular sympathetic regulation in the rat. Effects on sympathetic tone were first determined in anaesthetised animals following i.v. administration of the drugs. Central effects were evaluated in anaesthetised rats

The main clinically used antidepressant drugs are selective monoamine reuptake inhibitors, including selective serotonin reuptake inhibitors (citalopram, sertraline), selective dopamine reuptake inhibitor (nomifensine) and selective noradrenaline reuptake inhibitor (reboxetine), but they have

Acute exposure to delta 9-tetrahydrocannabinol (THC), the main psychoactive constituent of marijuana, produces a well-characterized set of neuroendocrine effects. The recent description of both brain cannabinoid receptors (CB-1) and anandamide, their proposed endogenous ligand, has renewed the

1. Previous work from our laboratory has shown that cannabis induces aggressive behaviour in rats that have been deprived of rapid eye movement (REM) sleep. It was suggested that this effect was related to brain catecholamines, with dopamine playing an agonist role and noradrenaline an inhibitory

The noradrenaline, dopamine and serotonin metabolites methoxyhydroxyphenylglycol (MHPG), homovanillic acid (HVA), and 5-hydroxyindoleacetic acid (5-HIAA), as well as the cyclic nucleotides c-AMP and c-GMP were estimated in urine samples of five normal volunteers. Ten control samples and two samples

The endocannabinoid system and the cannabinoid CB(1) receptors are involved in the development of ethanol tolerance and dependence. This study aimed to investigate the in vivo sensitivity of a CB(1) receptor agonist (WIN 55,212-2) modulating the synthesis of
