Amphetamine: Uses, Interactions, Mechanism of Action

The mechanism of action of amphetamine is complemented by the inhibition of the reuptake and of monoamine oxidase which acts synergistically to produce a significant increase the monoamine concentration, 1 This activity is not done as an inhibitor per se but more as a competitive substrate and thus, amphetamine is known to be a weak dopamine reuptake inhibitor, moderate noradrenaline …

Amphetamines

Generic mechanism of action of amphetamines: Synaptic terminals are endowed with vesicles that store reserves of neurotransmitters, which, in physiological conditions, are released through exocytosis into the synaptic cleft at a controlled rate, Amphetamines are, with few exceptions, psychostimulants of the releaser type, They increase extracellular neurotransmission by promoting the release

Amphetamine

From its mechanism of action, it has been demonstrated that amphetamine augments the concentration of noradrenaline in the prefrontal cortex and dopamine in the striatum on a dose and time-dependent manner, The indistinct release of neurotransmitters which include adrenaline is known to produce cardiovascular side effects, There are old reports of a cognitive enhancement related to the

Amphetamines – an overview

Nevertheless, amphetamines as a class of drug are characterized by a common mechanism of action, the possession of addictive properties, and the ability to elicit toxicity at both the central and peripheral level Carvalho et al,, 2012,

What is the Mechanism of action of Dexamphetamine

Mechanism of action, Amphetamine has the following mechanisms: Competitive inhibitor at DAT competing with dopamine and noradrenaline at NAT, Competitive inhibitor of VMAT; 3, High levels amphetamine will lead to the displacement of dopamine from the vesicle into the terminal, 4, Reversal of DAT, Metabolism: All types of AMPH are metabolised in the liver by side-chain oxidative deamination …

The pharmacology of amphetamine and methylphenidate

Amphetamine actions include dopamine and norepinephrine transporter inhibition, vesicular monoamine transporter 2 VMAT-2 inhibition, and monoamine oxidase activity inhibition, Methylphenidate actions include dopamine and norepinephrine transporter inhibition, agonist activity at the serotonin type 1A receptor, and redistribution of the VMAT-2, There is also evidence for interactions with

Amphetamine: Dosage, Mechanism/Onset of Action, Half-Life

Mechanism of Action, Amphetamines are noncatecholamine sympathomimetic amines that promote release of catecholamines primarily dopamine and norepinephrine from their storage sites in the presynaptic nerve terminals, A less significant mechanism may include their ability to block the reuptake of catecholamines by competitive inhibition, The anorexigenic effect is probably secondary to …

Adderall

Adderall and Mydayis are trade names for a combination drug containing four salts of amphetamine,The mixture is composed of equal parts racemic amphetamine and dextroamphetamine, which produces a 3:1 ratio between dextroamphetamine and levoamphetamine, the two enantiomers of amphetamine, Both enantiomers are stimulants, but differ enough to give Adderall an effects profile distinct from
