• Beschreibung

  Carvedilol is a vasodilating beta-blocker useful in the treatment of hypertension and angina pectoris. In addition to lowering blood pressure, carvedilol decreases total vascular resistance without the reflex tachycardia usually occurring with vasodilators. It is reported to be well tolerated with renal sparing effects.

• Beschreibung

  Carvedilol (Item No. 26286) is an analytical reference standard categorized as a β-adrenergic receptor antagonist and vasodilator. Formulations containing carvedilol have been used to enhance physical performance in athletes. This product is intended for use in analytical forensic applications. This product is also available as a general research tool .

• Definition

  ChEBI: A member of the class of carbazoles that is an adrenergic antagonist with non-selective beta- and alpha-1 receptor blocking properties which helps in the management of congestive heart failure.

• Manufacturing Process

  1-(9H-Carbazol-4-yloxy)-3-((2-(2-methoxyphenoxy)ethyl)amino)-2-propanol may be synthesized by the method of preparation of S-(-)-(1-carbazol-4- yloxy)-3-[2-(2-methoxyphenoxy)]ethylaminopropan-2-ol (Patent US 4,697,022 and 4,824,963).
  27.5 g 4-hydroxycarbazole are dissolved in a mixture of 150 ml 1 N aqueous sodium hydroxide solution and 70 ml dimethylsulfoxide. To this is added at ambient temperature 13.9 g epichlorohydrin, followed by stirring for 18 hours at ambient temperature. 280 ml water are then added thereto, followed by stirring for 15 min and filtering off with suction. The filter residue is washed with 0.1 N aqueous sodium hydroxide solution and water and subsequently dissolved in methylene chloride. The methylene chloride solution is dried over anhydrous sodium sulfate, treated with active charcoal and floridin and evaporated. 4-(2,3-Epoxypropoxy)-carbazole is purified by recrystallising twice from ethyl acetate. From the mother liquors there are isolated a further 4- (2,3-epoxypropoxy)-carbazole.
  10 g 4-(2,3-epoxypropoxy)-carbazole are, together with 13.97 g o-methoxyphenoxyethylamine, heated under reflux in 70 ml isopropanol for 2 hours. The solvent is evaporated off and the residue is stirred for 2 hours with a mixture of 115 ml toluene, 35 ml cyclohexane and 40 ml ethyl acetate. After filtering off with suction, the (1-carbazol-4-yloxy)-3-[2-(2-methoxyphenoxy)]-ethylaminopropan-2-ol is recrystallised from 150 ml ethyl acetate.

• Therapeutic Function

  Beta-adrenergic blocker

• Allgemeine Beschreibung

  Carvedilol (Coreg) is a β-blocker that hasa unique pharmacological profile. Like labetalol, it is aβ-blocker that possesses α1-blocking activity. Only the(S) enantiomer possesses the β-blocking activity, althoughboth enantiomers are blockers of the α1-receptor. Overall,its β-blocking activity is 10- to 100-fold of its α-blocking activity.

• Biologische Aktivität

  Potent β -adrenoceptor and α 1 -adrenoceptor antagonist (K i values are 0.81, 0.96 and 2.2 nM for β 1 -, β 2 - and α 1 -adrenoceptors respectively) that displays antihypertensive and peripheral vasodilatory activity. Blocks cardiac inward-rectifier K + (K IR ) channels, voltage-dependent Ca 2+ channels and exhibits antioxidant properties at higher concentrations.

• Biochem/physiol Actions

  Cavedilol is a non-selective β-adrenergic blocker with α1 blocking activity. Carvedilol is used specifically for the treatment of heart failure and high blood pressure. It has been shown to improve left ventricular ejection fraction and may reduce mortality.

• Clinical Use

  Carvedilol is also unique in that it possesses antioxidantactivity and an antiproliferative effect on vascular smoothmuscle cells. It thus has a neuroprotective effect and the abilityto provide major cardiovascular organ protection. It isused in treating hypertension and congestive heart failure.

• Veterinary Drugs and Treatments

  Carvedilol may be useful as adjunctive therapy in the treatment of heart failure (dilated cardiomyopathy) in dogs. There is a fair amount of controversy at present among veterinary cardiologists as to whether this drug will find a therapeutic niche.

• in vitro

  carvedilol potently inhibited fe2+-initiated lipid peroxidation in rat brain homogenate with an ic50 of 8.1 μm. in rat brain homogenate, carvedilol protected against fe2+-induced α-tocopherol depletion with an ic50 of 17.6 μm. carvedilol dose-dependently decreased the intensity of the dmpo-oh signal, with an ic50 of 25 μm [1]. carvedilol prevented vascular smooth muscle cell migration, proliferation, and neointimal formation following vascular injury. in human cultured pulmonary artery vascular smooth muscle cells, carvedilol (0.1-10 μm) concentration-dependently inhibited the mitogenesis stimulated by platelet-derived growth factor, epidermal growth factor, thrombin, and serum, with ic50 values ranging from 0.3 to 2.0 μm. carvedilol concentration-dependently inhibited vascular smooth muscle cell migration induced by platelet-derived growth factor with an ic50 value of 3 μm [3].

Moxisylyte: possible severe postural hypotension. Sympathomimetics: severe hypertension with adrenaline and noradrenaline and possibly with dobutamine.

• Stoffwechsel

  Carvedilol is subject to considerable first-pass metabolism in the liver; the absolute bioavailability is about 25%. It is extensively metabolised in the liver, primarily by the cytochrome P450 isoenzymes CYP2D6 and CYP2C9, and the metabolites are excreted mainly in the bile.
