or. Nagai Nagayoshi, a Japanese chemist and pharmacologist, first isolated ephedrine in 1885. [27][39][40] Although very rare, this psychosis can also occur at therapeutic doses during long-term therapy. [sources 14] SLC1A1 is excitatory amino acid transporter 3 (EAAT3), a glutamate transporter located in neurons, SLC22A3 is an extraneuronal monoamine transporter that is present in astrocytes, and SLC22A5 is a high-affinity carnitine transporter. In particular, amphetamine may decrease the effects of sedatives and depressants and increase the effects of stimulants and antidepressants. [181] The elimination half-life of lisdexamfetamine is generally less than 1 hour.[181]. [134] The review indicated that the severity of withdrawal symptoms is positively correlated with the age of the individual and the extent of their dependence. [27][77], According to the International Programme on Chemical Safety (IPCS) and the United States Food and Drug Administration (USFDA),[note 8] amphetamine is contraindicated in people with a history of drug abuse,[note 9] cardiovascular disease, severe agitation, or severe anxiety. There have been fears that long-term use of amphetamines for ADHD could affect brain development, prevent physical growth, and increase the risk of drug abuse later in life. [27], Amphetamine exerts its behavioral effects by altering the use of monoamines as neuronal signals in the brain, primarily in catecholamine neurons in the reward and executive function pathways of the brain. [200] Dextroamphetamine sulfate is the most common enantiopure salt. Amphetameme. Recent Post by Page. Amphetamine is also used as an athletic performance enhancer and cognitive enhancer, and recreationally as an aphrodisiac and euphoriant. Last medically reviewed on December 22, 2017, People with rheumatoid arthritis (RA) can benefit greatly from developing a daily exercise routine.

Amphetamines and amphetamine derivatives have been used in the past to treat narcolepsy. It is used to treat some medical conditions, but it is also highly addictive, with a history of abuse. [77][78][79] Amphetamine and other dopaminergic drugs also increase power output at fixed levels of perceived exertion by overriding a "safety switch", allowing the core temperature limit to increase in order to access a reserve capacity that is normally off-limits. ToonHub. [205] For example, racemic amphetamine can be treated with d-tartaric acid to form a diastereoisomeric salt which is fractionally crystallized to yield dextroamphetamine. Amphetamines are used for recreational purposes. Transcription factors are proteins that increase or decrease the. [110][112][131] In particular, aerobic exercise decreases psychostimulant self-administration, reduces the reinstatement (i.e., relapse) of drug-seeking, and induces increased dopamine receptor D2 (DRD2) density in the striatum. Methamphetamine is a powerful, highly addictive stimulant that affects the central nervous system. creds … Visit cvs.com … People take it to boost libido, increase wakefulness, improve cognitive control, enhance sociability, and induce euphoria. AMC's Breaking Bad, a crime drama series revolving around the large-scale illicit production of methamphetamine, has been lauded by critics and audiences alike for its realist approach to the portrayal of the international drug trade.It has also been called a "contemporary western" by series creator Vince Gilligan.. [11], The prodrug lisdexamfetamine is not as sensitive to pH as amphetamine when being absorbed in the gastrointestinal tract;[181] following absorption into the blood stream, it is converted by red blood cell-associated enzymes to dextroamphetamine via hydrolysis. 881K likes. [27][38] Less common side effects include anxiety, change in libido, grandiosity, irritability, repetitive or obsessive behaviors, and restlessness;[sources 8] these effects depend on the user's personality and current mental state. [36] Upon entering the presynaptic neuron, amphetamine activates TAAR1 which, through protein kinase A (PKA) and protein kinase C (PKC) signaling, causes DAT phosphorylation. It is a prescription drug in many countries, and unauthorized possession and distribution of amphetamine are often tightly controlled due to the significant health risks associated with recreational use. [27] Amphetamine may also decrease the effects of antihypertensives and antipsychotics due to its effects on blood pressure and dopamine respectively. When amphetamines are used at higher doses and through routes that are not prescribed by a doctor, they can have severe adverse effects. Very high doses can result in psychosis (e.g., delusions and paranoia) which rarely occurs at therapeutic doses even during long-term use. Amphetamine is not available for Windows but there are some alternatives that runs on Windows with similar functionality. [212][213] A third route starts with ethyl 3-oxobutanoate which through a double alkylation with methyl iodide followed by benzyl chloride can be converted into 2-methyl-3-phenyl-propanoic acid. [sources 14] Amphetamine is known to strongly induce cocaine- and amphetamine-regulated transcript (CART) gene expression,[4][163] a neuropeptide involved in feeding behavior, stress, and reward, which induces observable increases in neuronal development and survival in vitro.
