Long-term amphetamine exposure at sufficiently high doses in some animal species is known to produce abnormal dopamine system development or nerve damage, but, in humans with ADHD, long-term use of pharmaceutical amphetamines at therapeutic doses appears to improve brain development and nerve growth. Īmphetamine is used to treat attention deficit hyperactivity disorder (ADHD), narcolepsy (a sleep disorder), and obesity, and is sometimes prescribed off-label for its past medical indications, particularly for depression and chronic pain. Phenethylamine is the parent compound of amphetamine, while N-methylphenethylamine is a positional isomer of amphetamine that differs only in the placement of the methyl group. As a member of the phenethylamine class, amphetamine is also chemically related to the naturally occurring trace amine neuromodulators, specifically phenethylamine and N-methylphenethylamine, both of which are produced within the human body. It is also the parent compound of its own structural class, the substituted amphetamines, which includes prominent substances such as bupropion, cathinone, MDMA, and methamphetamine. Īmphetamine belongs to the phenethylamine class. Recreational doses are generally much larger than prescribed therapeutic doses and carry a far greater risk of serious side effects. Very high doses can result in psychosis (e.g., delusions and paranoia) which rarely occurs at therapeutic doses even during long-term use. Addiction is a serious risk with heavy recreational amphetamine use, but is unlikely to occur from long-term medical use at therapeutic doses. Larger doses of amphetamine may impair cognitive function and induce rapid muscle breakdown. It induces physical effects such as improved reaction time, fatigue resistance, and increased muscle strength. Īt therapeutic doses, amphetamine causes emotional and cognitive effects such as euphoria, change in desire for sex, increased wakefulness, and improved cognitive control. Amphetamine increases monoamine and excitatory neurotransmission in the brain, with its most pronounced effects targeting the norepinephrine and dopamine neurotransmitter systems. Currently, pharmaceutical amphetamine is prescribed as racemic amphetamine, Adderall, dextroamphetamine, or the inactive prodrug lisdexamfetamine. The first amphetamine pharmaceutical was Benzedrine, a brand which was used to treat a variety of conditions. 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. Amphetamine is also used as an athletic performance enhancer and cognitive enhancer, and recreationally as an aphrodisiac and euphoriant. Historically, it has been used to treat nasal congestion and depression. The term is frequently used informally to refer to any combination of the enantiomers, or to either of them alone.

Amphetamine properly refers to a specific chemical, the racemic free base, which is equal parts of the two enantiomers in their pure amine forms.

Amphetamine was discovered in 1887 and exists as two enantiomers: levoamphetamine and dextroamphetamine. īe sure to check with your doctor or pharmacist when in doubt.Amphetamine (contracted from alpha- methyl phen ethyl amine) is a central nervous system (CNS) stimulant that is used in the treatment of attention deficit hyperactivity disorder (ADHD), narcolepsy, and obesity. Pill splitting is also not recommended for situations where the patient might not understand the concept or be capable of splitting a pill. Don't split drugs with an enteric coating (designed to protect the stomach), drugs that are time-release or long-acting, drugs taken more often than once a day, drugs in capsules, and prepackaged drugs in specific doses, like birth control pills. Some immediate-release tablets may be split, and tablets that are scored have been evaluated by the FDA for safety. Pill splitters can be bought at most pharmacies for around $5. Some important things to consider before pill splitting: You'll need to ask your doctor if pill splitting is a good idea for your prescription if so, they will need to adjust your prescription accordingly. While it may seem odd, the 40mg version of the same drug typically does not cost twice as much as the 20mg-in fact, it often costs the exact same amount! Here's how it works: Imagine you take the 20mg dosage of a certain drug. You may be able to save up to 50% each month by splitting a higher dosage of this drug.
