Pharmakologische Informationen
Pharmacodynamics
This drugs acts as an antitussive, bronchodilator, and adrenergic receptor agonist. It stimulates the alpha and beta adrenergic receptors, relieving cough and congestion. As with other adrenomimetic amines, the drugs in this class are much less potent than norepinephrine itself. Members of this class of drugs increase both systolic and diastolic blood pressure, cardiac contractility, and cardiac output; in general, however, they do not increase heart rate. Bronchial smooth muscle relaxation of prolonged duration occurs, and pupils dilate.
Mechanism of Action
The pharmacology of methylephedrine is similar to that of other members of the ephedra alkaloid class of drugs. These compounds are sympathomimetic amines because they mimic the effects of the catecholamines on the sympathetic nervous system. These alkaloids permeate the blood-brain barrier and have a direct central nervous system stimulant effect with peripheral effects; the peripheral effects are indirect and primarily mediated by norepinephrine release. Methylephedrine expands the bronchia by relaxing the bronchial muscles. The decrease in urination with sympathomimetic use is increased through activation of the alpha-adrenoceptors of the smooth muscles of the bladder.
Biological Half-Life3-6 hours (Ephedrine).
Metabolism/MetabolitesMethylephedrine is metabolized to give ephedrine and norephedrine.
Absorption, Distribution and Excretion
Methylephedrine is rapidly absorbed following oral administration. Peak plasma concentrations of ephedrine (from which methylephedrine is derived) occur 2-3h after administration. Due to the fact that methylephedrine is a derivative of ephedrine, peak plasma concentrations are likely similar.
The primary compound excreted in urine is unchanged methylephedrine (33-40% of dose), followed by the metabolite _methylephedrine-N-oxide_ (15% of dose), and approximately 8% of the dose excreted as ephedrine after 24 hours. About 70% of the dose is excreted in the urine as metabolites over 72 hours. Alkaline urine reduces elimination to 20-35% of the dose.
Ephedrine: 2.5-3.0 L/kg. Methylephedrine is a derivative of ephedrine and quickly distributed throughout the body.
