[Metabolism of catecholamines in children with attention deficit syndrome with hyperactivity]
Unlabelled:
The aim of research was to study catecholamine excretion peculiarities of the children with attention deficit hyperactivity disorder (ADHD). 25 children at the age of 7-9 years took part in this research. High-pressure liquid chromatography (HPLC) was used for measuring the content of catecholamine. The content of catecholamine was defined in the morning samples of urine. The examination showed, that ADHD children had the basal level of epinephrine and norepinephrine more than the normal control in 3.9 and 5.4 times. After cognitive tests the content of norepinephrine reduced in the ADHD group in 2.1 times in the comparison with normal control. On the contrary content of epinephrine increased in 2.8 times.
Conclusion:
Simpatico-adrenal system hyperactivity (especially it's adrenals component) characterized ADHD children.

Adrenergic Agonists: Indirect-Acting Agents
One mechanism involves depleting stored catecholamines by displacing them from synaptic vesicles. These agents, known as "displacers," are transported into vesicles at the expense of noradrenaline. Examples include amphetamine and tyramine, which lack a catechol moiety, resulting in prolonged action, improved oral bioavailability, and...
Adrenergic Agonists: Mixed-Action Agents
Ephedrine and pseudoephedrine lack a catecholamine group, making them less susceptible to degradation by metabolic enzymes. They have increased oral bioavailability and lipophilicity, resulting in a longer duration of action. Their response is reduced by...
