High impact information on ritanserin

  • We have recently demonstrated that ritanserin, a serotonin 5-hydroxytryptamine receptor antagonist void of systemic effects, caused a significant reduction of portal pressure in conscious cirrhotic dogs [9].
  • The mechanism by which ritanserin lowers portal pressure is poorly defined [9].
  • Portal vascular resistance decreased significantly (-23%), whereas splanchnic arteriolar resistance was similar before and after ritanserin [9].
  • The requirement for functional 5-HT2B receptors between 8 and 9 days postcoitum is supported by culture of embryos exposed to 5-HT2-specific ligands; 5-HT2B high-affinity antagonist such as ritanserin, induced morphological defects in the cephalic region, heart and neural tube [10].
  • Ritanserin administration to rats subjected to bile duct ligation significantly reduced portal pressure (from 16.2 +/- 1.3 mm Hg to 12.3 +/- 0.7 mm Hg; mean decrease, 22% +/- 5%; p < 0.05) [1].

Gene context of ritanserin

  • The latter was abolished by treatment with the 5-HT2 receptor antagonist, ritanserin [27].
  • Risperidone is at least as potent as the specific 5-HT2 receptor antagonist ritanserin in these tests [28].
  • The 5-HT receptor antagonists metergoline (non-specific receptor subtypes 1 and 2), or ritanserin (selective 2C), or GR55562 (selective l B) was injected into the PVN prior to enterostatin (0.01 nmol) injection into the amygdala [29].
  • The LTP-inhibiting effect of DOI (10 microM) was blocked by the 5-HT2,7 receptor antagonist ritanserin (10 microM), but not by the 5-HT1A receptor antagonist NAN-190 (10 microM) nor by the 5-HT3,4 receptor antagonist MDL72222 (10 microM) [30].
  • The 5-HT2 antagonists ketanserin and ritanserin, the 5-HT3 antagonist ICS 205-930 and the alpha 2 adrenoceptor antagonist idazoxan did not oppose the hypophagic effect of mCPP [31].
 

Analytical, diagnostic and therapeutic context of ritanserin

  • Using conscious dogs, we investigated the effect of the chronic oral administration of a new specific antiserotonergic drug, ritanserin (10 mg per day for 5 days), on portal pressure and systemic hemodynamics [15].
  • Two 5-HT2/1C receptor antagonists, ritanserin (0.05-10.0 mg/kg) and ICI 169.369 (0.3-10.0 mg/kg), were also devoid of specific effects upon defensive analgesia [32].
  • In the present study, this relationship was reevaluated by spectral analysis of the sleep electroencephalogram (EEG) and deconvolution analysis of the plasma GH concentrations during normal nocturnal sleep and after enrichment in SWS by means of ritanserin, a selective 5-HT2 receptor antagonist [33].
  • GBR 12909 reliably maintained self-administration, and ritanserin increased response rate maintained by the highest dose [34].
  • We demonstrated that intraperitoneal injection of 5 mg/kg DOI produced a long-lasting decrease in respiratory frequency and tidal volume, which could be blocked by the antagonist ritanserin [35].
