The cardiovascular responses reported in man include moderate tachycardia , unchanged or augmented stroke volume , enhanced cardiac output , variable alterations in peripheral resistance and usually a rise in blood pressure.

It stimulates the cerebral cortex and subcortical centers, which accounts for its use in narcolepsy . Archived. Ephedrine is a medication and stimulant. it acts indirectly to release NE from nerve terminals it has direct agonist effect on all adrenergic subtypes (ephedrine, amphetamine) has more CNS effects. Re: Ephedrine (Method of Action??) It can be taken by mouth or by injection into a muscle, vein, or just under the skin. Pseudoephedrine, also known as D-psi-ephedrine or trans-ephedrine, belongs to the class of organic compounds known as phenylpropanes. Ephedrine promotes modest short-term weight loss, specifically fat loss, and is used by some body builders to reduce body fat before a competition. Because ephedrine causes release of norepinephrine, patients taking MAOIs can have an exaggerated hypertensive effect.Concurrent treatment with NSAIDs, tricyclic antidepressants and ganglionic blocking agents can increase risk of hypertension.Ephedrine should not be administered within 2 weeks of a patient receiving a monoamine oxidase inhibitor, e.g. This is due to an effect of ephedrine to cause venoconstriction, thereby improving preload, cardiac output, and uterine blood flow.We use cookies to help provide and enhance our service and tailor content and ads.

Previously, ephedrine was the first-line therapy for parturients with hypotension secondary to spinal or epidural anesthesia based on studies in pregnant ewes suggesting that ephedrine preserved uterine blood flow compared with other vasopressors.At higher doses, ephedrine causes hypertension and tachycardia. enhanced release of NE, dopamine, serotonin.which amphetamine isomer has more CNS effects?ephedrine is taken up into nerve terminal >> displaces NE from storage sites in vesicles >> the rereleased NE acts on receptors.what is special about "mixed action" amine?it acts indirectly to release NE from nerve terminals.
These are organic compounds containing a phenylpropane moiety. Ephedrine sulfate also has a potent effect on the CNS.
