Dược Lực Học :
Lisdexamfetamine is a pro-drug of dextroamphetamine. It works primarily by inducing the release of the neurotransmitters dopamine and norepinephrine from their storage areas in nerve terminals. Both of these transmitters contribute to maintaining alertness, increasing focus, and sustaining thought, effort, and motivation.
Cơ Chế Tác Dụng :
Lisdexamfetamine (L-lysine-d-amphetamine) is a prodrug of the psychostimulant d-amphetamine coupled with the essential amino acid L-lysine. It was developed so that the amphetamine psychostimulant is released and activated more slowly as the prodrug molecule is hydrolyzed consequently cleaving off the amino acid-during the first pass through the intestines and/or the liver. Amphetamines target the trace amine-associated receptor 1 (TAAR1). Amphetamine is also believed to exert its effects by binding to the monoamine transporters (the dopamine transporter or DAT) and increasing extracellular levels of the biogenic amines dopamine, norepinephrine (noradrenaline) and serotonin.
Lisdexamfetamine is a pro-drug of dextroamphetamine. Amphetamines are thought to block the reuptake of norepinephrine and dopamine into the presynaptic neuron and increase the release of these monoamines into the extraneuronal space. Norepinephrine and dopamine contribute to maintaining alertness, increasing focus, and sustaining thought, effort, and motivation. However, the exact therapeutic action in ADHD is not known.
Dược Động Học :
▧ Absorption :
After oral administration, lisdexamfetamine is rapidly absorbed from the gastrointestinal tract.
▧ Metabolism :
Lisdexamfetamine is converted to dextroamphetamine and L-lysine, which is believed to occur by first-pass intestinal and/or hepatic metabolism. Lisdexamfetamine is not metabolized by cytochrome P450 enzymes.
▧ Half Life :
The plasma elimination half-life of lisdexamfetamine typically averaged less
than one hour.
Độc Tính :
Manifestations of acute overdosage with amphetamines include restlessness, tremor, hyperreflexia, rapid respiration, confusion, assaultiveness, hallucinations, panic states, hyperpyrexia and rhabdomyolysis. Fatigue and depression usually follow the central nervous system stimulation. Cardiovascular effects include arrhythmias, hypertension or hypotension and circulatory collapse. Gastrointestinal symptoms include nausea, vomiting, diarrhea, and abdominal cramps. Fatal poisoning is usually preceded by convulsions and coma.
Chỉ Định :
For the treatment of Attention Deficit/Hyperactivity Disorder (ADHD) in pediatric populations aged 6 to 12 years.
Tương Tác Thuốc :
-
Tramadol
Increased risk of serotonin syndrome. Monitor for symptoms of serotonin syndrome.
-
Trandolapril
Lisdexamfetamine may reduce the efficacy of Trandolapril.
-
Tranylcypromine
The MAO inhibitor, Tranylcypromine, may increase the vasopressor effect of the amphetamine, Lisdexamfetamine. Concomitant therapy should be avoided.
-
Triprolidine
Triprolidine may reduce the sedative effect of the antihistamine, Lisdexamfetamine.
