Ketanserin, a serotonin receptor antagonist (S2), lowered blood pressure in patients with essential hypertension; at three months 72% (13/18) had a successful reduction in pressure. No marked orthostatic changes were noted. Older patients... more
Several lines of evidence suggest that a disturbance of serotonin neuronal pathways may contribute to the pathogenesis of anorexia nervosa (AN). This study applied positron emission tomography (PET) to investigate the brain serotonin 2A... more
Different analgesic combinations with caffeine have shown this drug to be capable of increasing the analgesic effect. Many combinations with nonsteroidal anti-inflammatory drugs (NSAIDs) have been carried out, but, in regard to opioids,... more
Background Serotonin receptors may play an important role in the pathophysiology of affective disorders. We studied type-2 serotonin (5-HT2) receptors in the brain of patients with major depression. Method Using positron emission... more
Serotonin (5-hydroxytryptamine, 5-HT) is a vasoconstrictor and mitogen whose levels are elevated in diabetes. Previous studies have shown the presence of 5-HT2A, 5-HT2B, and 5-HT1B receptors in vascular smooth muscle cells (VSMCs). There... more
Porcine Pseudomonas adult respiratory distress syndrome (ARDS) has been shown to respond to combination therapy of 150 mg of cimetidine, 12.5 mg/kg of ibuprofen, 10 mg/kg of diphenhydramine, 0.2 mg/kg of ketanserin, and 30 mg/kg of... more
The central nervous system control of food intake has been extensively studied, hence, several neurotransmitter systems regulating this function are now clearly identified, for example, the endocannabinoid and serotoninergic systems. The... more
To examine the role of 5-HT2 receptors in the central cardiorespiratory network, and in particular the respiratory modulation of parasympathetic activity to the heart, we used an in vitro medullary slice that allowed simultaneous... more
Alpha-methyl-5-HT is widely used as a high-affinity 5-HT(2) receptors agonist, though some studies have postulated that this drug also activates other serotonergic receptors. In the present work, we found that a wide range of... more
The cardiovascular effects of the selective 5 HT2-serotonergic antagonist Ketanserin (cumulative doses of 0.01, 0.04, 0.16, 0.64 and 2.5 mg.kg-1 i.v. at 30 min intervals) were investigated in closed-chest, anesthetized dogs with... more
Sensory processing deficits are a hallmark of schizophrenia and can be demonstrated by recording auditory evoked potentials (AEPs) elicited in response to closely paired click stimuli. In nonschizophrenic humans, as well as in rats, the... more
