Introduction:
The annual growth of psychiatric and neurodegenerative diseases requires new therapeutic strategies for delivering active pharmaceutical molecules to the brain. Non-invasive intranasal drug delivery is a promising method that allows bypassing of the blood-brain barrier and the liver de-toxification system.
Results:
The review discusses the main results of experimental studies of the effect of intranasal substances of amino acid and peptide nature on the monoamine systems of the brain. The main attention is paid to understanding the transport mechanisms of potential amino acid and peptide drugs in the nose-to-brain projection and assessing their therapeutic efficacy.
Conclusion:
The obtained results indicate the possibility of creating, along with buccal, in-halation, transdermal and ocular preparations, intranasal non-invasive drugs that provide more effective therapy for psychiatric and neurodegenerative diseases, such as schizophrenia, depression, anxiety, ADHD, Alzheimer disease and Parkinson disease.

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...

Adrenergic Agonists: Chemistry and Structure-Activity Relationship
Aromatic ring substitutions: Substituting the aromatic ring with –OH groups at positions 3 and 4 yields catecholamines (e.g., epinephrine), which have a high affinity for adrenoceptors. Hydrogen bonding between –OH groups and receptors enhances adrenergic activity.
