Metoprolol tartrate Chemische Eigenschaften,Einsatz,Produktion Methoden

Beschreibung
Metoprolol (tartrate) (Item No. 21165) is an analytical reference standard categorized as a β₁-adrenergic receptor blocker. This product is intended for use in analytical forensic applications. Metoprolol (succinate) is available as a general research tool .
Chemische Eigenschaften
White or almost white, crystalline powder or colourless crystals.
Originator
Betaloc,Astra,UK,1975
Verwenden
A b1-Adrenergic blocker
Verwenden
alpha(1)-adrenergic blocker
Verwenden
A β1 selective aryloxypropanolamine andrenergic antagonist. Used in the treatment of a variety of cardiovascular disorder. Antihypertensive; antianginal; antiarrhythmic (class II).
Verwenden
Metoprolol tartrate is an antagonist of the β1-AR (β1-adrenoceptor). It inhibits spontaneous endothelin-1 production in vitro and displays antihypertensive and antianginal activity in vivo.
Verwenden
A selective aryloxypropanolamine andrenergic antagonist. Used in the treatment of a variety of cardiovascular disorder. Antihypertensive; antianginal; antiarrhythmic (class II)
Manufacturing Process
The starting material 1,2-epoxy-3-[p-(β-methoxyethyl)phenoxy]-propane was obtained from p-(β-methoxyethyl)-phenol which was reacted with epichlorohydrin whereafter the reaction product was distilled at 118°C to 128°C at a pressure of 0.35mm Hg.
1,2-Epoxy-3-[p-(β-methoxyethyl)-phenoxy]-propane (16.7g) was dissolved in 50 ml isopropanol and mixed with 20 ml isopropylamine. The mixture was heated in an autoclave on boiling water-bath overnight, whereafter it was evaporated and the remainder dissolved in 2 N HCI. The solution was extracted first with ether and thereafter with methylene chloride. After evaporating the methylene chloride phase, the hydrochloride of 1- isopropylamino-3-[p(β-methoxyethyl)-phenoxy] -propanol-2 was obtained which, after recrystallization from ethyl acetate, weighed 10.4 g. Melting point 83°C. Equivalent weight: found 304.0, calculated 303.8.
The hydrochloride is then converted to the tartrate.
Trademarks
Lopressor (Novartis).
Therapeutic Function
Beta-adrenergic blocker
Allgemeine Beschreibung
A certified solution standard applicable for use in clinical toxicology or forensic analysis by LC-MS/MS or GC/MS. Metoprolol is used for the treatment of multiple heart conditions including hypertension, angina, and tachycardia. This beta blocker is sold under the trade names Lepressor and Toprol XL.
Biologische Aktivität
Selective β 1 -adrenoceptor antagonist (K i values are 47, 2960 and 10100 nM for β 1 , β 2 and β 3 adrenoceptors respectively). Inhibits spontaneous endothelin-1 production in vitro and displays antihypertensive and antianginal activity in vivo .
Clinical Use
Beta-adrenoceptor blocker:
Hypertension
Angina
Cardiac arrhythmias
Migraine prophylaxis
Hyperthyroidism
Veterinary Drugs and Treatments
Because metoprolol is relatively safe to use in animals with bronchospastic disease, it is often chosen over propranolol. It may be effective in supraventricular tachyarrhythmias, premature ventricular contractions (PVC’s, VPC’s), systemic hypertension, and treating cats with hypertrophic cardiomyopathy. There is increasing interest in using beta blockers in heart failure in dogs; one retrospective study showed increased survival times when dogs were given metoprolol, but definitive prospective, double-blinded studies have not been reported documenting the benefit (increased survival) of beta-blockers in dogs with heart failure.
Arzneimittelwechselwirkung
Potentially hazardous interactions with other drugs
Anaesthetics: enhanced hypotensive effect.
Analgesics: NSAIDs antagonise hypotensive effect.
Anti-arrhythmics: increased risk of myocardial depression and bradycardia; increased risk of bradycardia, myocardial depression and AV block with amiodarone; increased risk of myocardial depression and bradycardia with flecainide; concentration increased by propafenone and dronedarone.
Antibacterials: concentration reduced by rifampicin.
Antidepressants: enhanced hypotensive effect with MAOIs; concentration increased by citalopram and escitalopram and possibly by paroxetine - avoid.
Antihypertensives; enhanced hypotensive effect; increased risk of withdrawal hypertension with clonidine; increased risk of first dose hypotensive effect with post-synaptic alpha-blockers such as prazosin.
Antimalarials: increased risk of bradycardia with mefloquine; avoid with artemether/lumefantrine.
Antipsychotics enhanced hypotensive effect with phenothiazines.
Antivirals: avoid concomitant use with tipranavir in heart failure.
Calcium-channel blockers: increased risk of bradycardia and AV block with diltiazem; hypotension and heart failure possible with nifedipine and nisoldipine; asystole, severe hypotension and heart failure with verapamil.
Cytotoxics: possible increased risk of bradycardia with crizotinib.
Diuretics: enhanced hypotensive effect.
Fingolimod: possibly increased risk of bradycardia.
Moxisylyte: possible severe postural hypotension.
Stoffwechsel
Extensively metabolised in the liver, mainly by the cytochrome P450 isoenzyme CYP2D6, and undergoes oxidative deamination, O-dealkylation followed by oxidation, and aliphatic hydroxylation. The metabolites are excreted in the urine with only small amounts of unchanged metoprolol.
