Evekeo (amphetamine sulfate tablets, USP) is indicated for: 1. Narcolepsy 2. Attention Deficit Disorder with Hyperactivity as an integral part of a total treatment program which typically includes other remedial measures (psychological, educational, social) for a stabilizing effect in children with behavioral syndrome characterized by the following group of developmentally inappropriate symptoms: moderate to severe distractibility, short attention span, hyperactivity, emotional lability , and impulsivity. The diagnosis of the syndrome should not be made with finality when these symptoms are only of comparatively recent origin. Nonlocalizing (soft) neurological signs, learning disability, and abnormal EEG may or may not be present, and a diagnosis of central nervous system dysfunction may or not be warranted. 3. Exogenous Obesity as a short term (a few weeks) adjunct in a regimen of weight reduction based on caloric restriction for patients refractory to alternative therapy, e.g., repeated diets, group programs, and other drugs. /Included in US product label/

/BOXED WARNING/ Amphetamines have a high potential for abuse. Administration of amphetamines for prolonged periods of time may lead to drug dependence and must be avoided. Particular attention should be paid to the possibility of subjects obtaining amphetamines for non-theraputic use or distribution to others, and the drugs should be prescribed or dispensed sparingly. Misuse of amphetamine may cause sudden death and serious cardiovascular adverse events.

Amphetamines should be used during pregnancy only if the potential benefits justify the possible risks to the fetus. During pregnancy it is questionable whether potential benefits from amphetamines outweigh potential risks. Infants born to women dependent on amphetamines have an increased risk of prematurity, low birthweight, and withdrawal symptoms (e.g., dysphoria, lassitude, agitation).

Adverse effects of amphetamines may include nervousness, insomnia, irritability, talkativeness, changes in libido, dizziness, headaches, increased motor activity, chilliness, pallor or flushing, blurred vision, mydriasis, and hyperexcitability. Exacerbation of motor or phonic tics, Tourette's syndrome, dyskinesia, seizures, euphoria, dysphoria, emotional lability, and impotence have been reported in patients receiving amphetamines. Psychotic episodes have occurred rarely in patients receiving amphetamines at recommended dosages.

Amphetamine is indicated for the treatment of attention-deficit/hyperactivity disorders (ADHD) as well as for the treatment of central nervous system disorders such as narcolepsy. ADHD is a complex disorder associated with the substantial heterogeneity in etiology, clinical presentation, and treatment outcome. ADHD comes from a complex interplay between interdependent genetic and non-genetic factors which cause complex mental disorders in children and teenagers. On the other hand, narcolepsy is a chronic sleep disorder typically resenting during adolescence and characterized by excessive daytime sleepiness. Amphetamine is also being used nowadays off-label for the treatment of obesity, depression and chronic pain.
FDA Label
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 administration of amphetamine in which improvements in intelligence test scores were reported. In ADHD, amphetamine has been largely showed to produce remarkable improvements in school performance, behavior, and demeanor. The effect was shown to be produced through both racemic forms and to this date, the use of racemic forms 3:1 (D:L) is very common. The therapeutic effect of amphetamine on serotonin does not seem to have a significant clinical effect on ADHD as observed on comparative studies with amphetamine and fenfluramine, a powerful serotonin releasing factor. However, the indirect effect on serotonin might have an effect on the depression and anxiety profile of ADHD. Studies regarding the illicit use of amphetamine in which heavy consumers were studied proved the generation of a paranoid state which flagged this drug as a psychiatric danger compound. This observation was supported by the continuous reports of misuse in patients under depression.
Central Nervous System Stimulants
A loosely defined group of drugs that tend to increase behavioral alertness, agitation, or excitation. They work by a variety of mechanisms, but usually not by direct excitation of neurons. The many drugs that have such actions as side effects to their main therapeutic use are not included here. (See all compounds classified as Central Nervous System Stimulants.)
Dopamine Agents
Any drugs that are used for their effects on dopamine receptors, on the life cycle of dopamine, or on the survival of dopaminergic neurons. (See all compounds classified as Dopamine Agents.)
Dopamine Uptake Inhibitors
Drugs that block the transport of DOPAMINE into axon terminals or into storage vesicles within terminals. Most of the ADRENERGIC UPTAKE INHIBITORS also inhibit dopamine uptake. (See all compounds classified as Dopamine Uptake Inhibitors.)
Adrenergic Agents
Drugs that act on adrenergic receptors or affect the life cycle of adrenergic transmitters. Included here are adrenergic agonists and antagonists and agents that affect the synthesis, storage, uptake, metabolism, or release of adrenergic transmitters. (See all compounds classified as Adrenergic Agents.)
Adrenergic Uptake Inhibitors
Drugs that block the transport of adrenergic transmitters into axon terminals or into storage vesicles within terminals. The tricyclic antidepressants (ANTIDEPRESSIVE AGENTS, TRICYCLIC) and amphetamines are among the therapeutically important drugs that may act via inhibition of adrenergic transport. Many of these drugs also block transport of serotonin. (See all compounds classified as Adrenergic Uptake Inhibitors.)
Sympathomimetics
Drugs that mimic the effects of stimulating postganglionic adrenergic sympathetic nerves. Included here are drugs that directly stimulate adrenergic receptors and drugs that act indirectly by provoking the release of adrenergic transmitters. (See all compounds classified as Sympathomimetics.)

Absorption
Amphetamine is well absorbed in the gut and as it is a weak base hence the more basic the environment the more of the drug is found in a lipid-soluble form and the absorption through lipid-rich cell membranes is highly favored. The peak response of amphetamine occurs 1-3 hours after oral administration and approximately 15 minutes after injection and it presents a bioavailability of over 75%. Complete amphetamine absorption is usually done after 4-6 hours.
Route of Elimination
The elimination of amphetamine is mainly via the urine from which about 40% of the excreted dose is found as unchanged amphetamine. About 90% of the administered amphetamine is eliminated 3 days after oral administration. The rate of elimination of amphetamine highly depends on the urine pH in which acidic pH will produce a higher excretion of amphetamine and basic pH produces a lower excretion.
Volume of Distribution
Amphetamine is reported to have a high volume of distribution of 4 L/kg.
Clearance
The reported normal clearance rate is of 0.7 L.h/kg. This clearance has been shown to get significantly reduced in patients with renal impairment reaching a value of 0.4 L.h/kg.
Children: Children eliminated amphetamine faster than adults.

Amphetamines are readily absorbed from the GI tract and effects persist for 4-24 hours. Amphetamines are distributed into most body tissues with high concentrations occurring in the brain and CSF. Amphetamine appears in the urine within about 3 hours following oral administration. Urinary excretion of the amphetamines is pH-dependent and excretion is enhanced in acidic urine. Following oral administration of racemic amphetamine to humans, approximately equal amounts of both isomers were excreted during the first 12 hours; after the first 12 hours, a continually decreasing proportion of the d-isomer was excreted.

Amphetamine is known to be metabolized by the liver under the action of the CYP2D6. The metabolic pathway of amphetamine is mainly defined by aromatic hydroxylation, aliphatic hydroxylation, and n-dealkylation. The formed metabolites in this pathway are 4-hydroxyamphetamine, 4-hydroxynorephedrine, hippuric acid, benzoic acid, benzyl methyl ketone, and p-hydroxyamphetamine which is known to be a potent hallucinogen. However, a significant part of the original compound remains unchanged.
Amphetamine is metabolized in the liver by aromatic hyroxylation, N-dealkylation, and deamination. Although the enzymes involved in amphetamine metabolism have not been clearly defined, cytochrome P450 (CYP-450) 2D6 is known to be involved with formation of 4-hydroxy-amphetamine. Because CYP2D6 is genetically polymorphic, population variations in amphetamine metabolism are a posibility.

Metabolism that results in aromatic hydroxylation, aliphatic hydroxylation, and n-dealkylation of amphetamines can give rise to active metabolites such as the potent hallucinogen p-hydroxyamphetamine. Other metabolic pathways, including deamination and subsequent side chain oxidation, produce inactive amphetamine derivatives.

The half-life of amphetamine highly depends on the isomer. For d-amphetamine, the reported half-life is of approximately 9-11 hours while for l-amphetamine the half-life is reported to be of 11-14 hours. The urine pH can modify this pharmacokinetic parameter which can vary from 7 hours in acid urine to 34 hours for alkaline urine.
Biological half-life is between 10-13 hr in adults and 9-11 hr in children.

It is important to consider that amphetamine has a very similar structure to the catecholamine neurotransmitters mainly on the presence of a long planar conformation, the presence of an aromatic ring and nitrogen in the aryl side chain. Amphetamine, as well as other catecholamines, is taken into presynaptic nerve terminals by the association with two sodium ions and one chloride ion. The complex of the amphetamine with the ions is actively transported by monoamine reuptake transporters. As amphetamine acts competitively with the endogenous monoamines, the greater the number of amphetamines the more internalized amphetamine will be found. Once inside the presynaptic terminal, amphetamine displaces other monoamines to be stored by VMAT2 which produces the pumping of the neurotransmitters into the synapse by a process called retro-transport. This process of release of neurotransmitters is approximately fourfold more potent in the d-isomer for the release of dopamine. 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. 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 reuptake inhibitor and very weak serotonin reuptake inhibitor. From this specific action, the l-isomer is known to be significantly less potent. Lastly, amphetamine is known to be an inhibitor of the mitochondrial-bound enzyme MAO which is the catalytic enzyme in charge of degrading all the excess of neurotransmitters. This mechanism of action is often overpassed as amphetamine is a weak MAO inhibitor but this mechanism cannot be dismissed.
Inactivation of sympathomimetic noncatecholamines largely depends on breakdown by monoamine oxidase and since substitution of an alkyl group for hydrogen on the a-carbon atom blocks enzymatic inactivation of the amino group, the duration of action of noncatecholamines (but not of catecholamines, which are inactivated largely by a different mechanism) is prolonged by a-substitution. The absence of a hydroxyl group on the aromatic ring of amphetamine reduces inactivation of the drug in the GI tract and the amphetamines are active following oral administration.
