α1-Adrenergic antagonist; derivative of Uracil (U801000). Antihypertensive. | [Biological Activity]
α 1 -adrenoceptor antagonist and 5-HT 1A receptor agonist (pIC 50 values are 6.13 and 6.4 respectively). Clinically used hypotensive agent. | [Description]
Urapidil(64887-14-5) is an antagonist of α1-adrenergic receptors (α1-ARs) and a partial agonist of the serotonin (5-HT) receptor subtype 5-HT1A.1,2 It selectively binds to α1- over α2-ARs (IC50s = 0.74 and 42 μM, respectively) and to 5-HT1A over 5-HT1B and 5-HT2 receptors (IC50s = 0.4, 20.4, and >10 μM, respectively) in rat cortex.1 Urapidil inhibits cAMP accumulation induced by forskolin in calf hippocampus as a functional model for 5-HT1A receptors (EC50 = 390 nM).3 It is also a β1-AR antagonist that inhibits the positive chronotropic response induced by isoproterenol (Item No. 15592) in isolated rat atria (pA2 = 6.05).4 Urapidil (1 μmol/kg, i.v.) lowers mean arterial pressure (MAP) in anesthetized cats, an effect that is reduced by central administration of the 5-HT1A receptor antagonist spiroxatrine.5
| [Side effects]
Side effects that may occur during treatment with uradil antihypertension include dizziness, fatigue, nausea, and light-headedness effects. The increases in systolic blood pressure heart rate caused by three progressive work loads bicycle exercise were not affected during urapidil, A slight reduction in forced expiratory volume was observed in some patients during treatment with beta-blocker. There was no case orthostatic hypotension during urapidil administration, despite its alpha1-blocking action. Side-effects were rare negligible[1]. | [References]
