response to amphetamine

Definition

Target type: biologicalprocess

Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of an amphetamine stimulus. Amphetamines consist of a group of compounds related to alpha-methylphenethylamine. [GOC:dph, GOC:ef]

Amphetamine, a psychostimulant drug, exerts its effects by modulating the activity of neurotransmitters, primarily dopamine, norepinephrine, and serotonin, within the central nervous system. The response to amphetamine involves a complex interplay of molecular events, leading to a cascade of cellular and behavioral effects.

Amphetamine's mechanism of action involves several key steps:

1. **Increased Neurotransmitter Release:** Amphetamine triggers the release of dopamine, norepinephrine, and serotonin from presynaptic neurons. It achieves this by reversing the function of monoamine transporters, specifically the dopamine transporter (DAT), norepinephrine transporter (NET), and serotonin transporter (SERT). These transporters normally remove neurotransmitters from the synaptic cleft, but amphetamine forces them to work in reverse, pushing more neurotransmitters into the synapse.

2. **Reduced Neurotransmitter Reuptake:** Amphetamine also inhibits the reuptake of dopamine, norepinephrine, and serotonin by blocking the transporters. This further contributes to an elevated concentration of these neurotransmitters in the synaptic cleft.

3. **Increased Neurotransmitter Synthesis:** Amphetamine can indirectly stimulate the synthesis of dopamine by enhancing the activity of tyrosine hydroxylase, the rate-limiting enzyme in dopamine biosynthesis.

4. **Activation of Postsynaptic Receptors:** The elevated levels of dopamine, norepinephrine, and serotonin in the synapse bind to and activate their respective receptors on postsynaptic neurons. This leads to a variety of downstream effects, including increased neuronal firing, changes in gene expression, and alterations in cellular signaling pathways.

5. **Behavioral Effects:** The activation of specific neural circuits by amphetamine results in characteristic behavioral responses, such as increased alertness, euphoria, and locomotor activity. The release of dopamine in the reward pathway is believed to contribute to the rewarding and addictive properties of the drug.

6. **Long-Term Effects:** Chronic use of amphetamine can lead to neuroadaptive changes, including downregulation of dopamine receptors and alterations in the expression of genes involved in neurotransmission. These adaptations may contribute to tolerance, dependence, and withdrawal symptoms.

In summary, the response to amphetamine involves a complex interplay of neurochemical and cellular events, ultimately resulting in a wide range of physiological and behavioral effects. Understanding the intricate mechanisms underlying amphetamine's actions is crucial for developing effective treatments for substance abuse and managing the potential risks associated with its use.'

Together with the neuropeptide vasopressin, it is believed to influence social cognition and behaviour.

Oxytocin: A nonapeptide hormone released from the neurohypophysis (PITUITARY GLAND, POSTERIOR). It differs from VASOPRESSIN by two amino acids at residues 3 and 8. Oxytocin acts on SMOOTH MUSCLE CELLS, such as causing UTERINE CONTRACTIONS and MILK EJECTION.

It is identical to banisterine, or telepathine, from Banisteria caapi and is one of the active ingredients of hallucinogenic drinks made in the western Amazon region from related plants. It has no therapeutic use, but (as banisterine) was hailed as a cure for postencephalitic PARKINSON DISEASE in the 1920's.

methyl 3,5-di-o-caffeoyl quinate3,5-dicaffeoylquinic acid methyl ester: results suggest that the effect of 3,5-dicaffeoylquinic esters on CHS is associated with a decrease in the production of interleukins, but not with the inhibition of iNOS expression. Moreover, esterification of the carboxyl group at C-1 enhanced protection against tyrosine nitration in the skin

clozapineclozapine : A benzodiazepine that is 5H-dibenzo[b,e][1,4]diazepine substituted by a chloro group at position 8 and a 4-methylpiperazin-1-yl group at position 11. It is a second generation antipsychotic used in the treatment of psychiatric disorders like schizophrenia.

Clozapine: A tricylic dibenzodiazepine, classified as an atypical antipsychotic agent. It binds several types of central nervous system receptors, and displays a unique pharmacological profile. Clozapine is a serotonin antagonist, with strong binding to 5-HT 2A/2C receptor subtype. It also displays strong affinity to several dopaminergic receptors, but shows only weak antagonism at the dopamine D2 receptor, a receptor commonly thought to modulate neuroleptic activity. Agranulocytosis is a major adverse effect associated with administration of this agent.
