amphetamine profile

Amphetamine: A powerful central nervous system stimulant and sympathomimetic. Amphetamine has multiple mechanisms of action including blocking uptake of adrenergics and dopamine, stimulation of release of monamines, and inhibiting monoamine oxidase. Amphetamine is also a drug of abuse and a psychotomimetic. The l- and the d,l-forms are included here. The l-form has less central nervous system activity but stronger cardiovascular effects. The d-form is DEXTROAMPHETAMINE. [Medical Subject Headings (MeSH), National Library of Medicine, extracted Dec-2023]

Effects

Amphetamine has a significant potential for abuse and addiction. It displaces intraneuronal stores of catecholamines, delaying their reuptake and inhibiting catabolism.

Amphetamine withdrawal has been less studied although it is a common problem with a prevalent rate of 87% among amphetamine users. Amphetamine psychosis has been considered to be a pharmacologic model of schizophrenia.

Actions

Amphetamine can increase conditioning to poor predictors of reinforcement in selective learning tasks. An amphetamine challenge may cause neurotoxicity in the human brain due to a decrease in omega-3 fatty acids and an increase in oxidative products. If amphetamine can enhance the therapeutic effects of TCT, this would provide strong support for a "PACT" treatment paradigm for schizophrenia.

Treatment

Amphetamine (AMPH) treatment can suppress appetite and increase oxidative stress in the brain. Treatment may be harmful in stroke recovery by making the brain more vulnerable to ischaemia.

Toxicity

We mapped 381 AEs from 148 case reports of generic tamsulosin, levothyroxine and amphetamine/dextroamphetamine to the physical, mental and social domain of the NIH Patient-Reported Outcomes Measurement Information System. The amphetamine-induced toxic effects were less prominent in CD-1 mice, which have much higher levels of Cu/Zn SOD activity.

Pharmacokinetics

The results suggest that the potentiation of the action of amphetamine by mianserin is mainly due to pharmacodynamic synergism and depends on the blockade of central serotonergic receptors. serum half-life and unchanged methamphetamine urine clearance were unaffected by any radiation dose. maximum methamphetamine concentrations and methamphetamine and amphetamine metabolite were not affected.

vitamin b 6 Vitamin B 6: VITAMIN B 6 refers to several PICOLINES (especially PYRIDOXINE; PYRIDOXAL; & PYRIDOXAMINE) that are efficiently converted by the body to PYRIDOXAL PHOSPHATE which is a coenzyme for synthesis of amino acids, neurotransmitters (serotonin, norepinephrine), sphingolipids, and aminolevulinic acid. During transamination of amino acids, pyridoxal phosphate is transiently converted into PYRIDOXAMINE phosphate. Although pyridoxine and Vitamin B 6 are still frequently used as synonyms, especially by medical researchers, this practice is erroneous and sometimes misleading (EE Snell; Ann NY Acad Sci, vol 585 pg 1, 1990). Most of vitamin B6 is eventually degraded to PYRIDOXIC ACID and excreted in the urine.	2.37	2	0
