The plant contains ephedrine and pseudoephedrine, which are natural alkaloids, or nitrogenous organic compounds that cause a physiological response in humans. These chemicals are the basis on which amphetamines (including methamphetamine) were created. Amphetamine is FDA-approved for the treatment of attention-deficit/hyperactivity disorder (ADHD) and narcolepsy.
What is the difference between amphetamine and methamphetamine?
- Amphetamines are used in treatments for ADD and ADHD, obesity, narcolepsy, and Parkinson’s disease, according to CESAR.
- If you inject meth with a needle, you also have a higher risk of contracting bloodborne viruses like hepatitis C.
- This can create an unhealthy drive to seek more pleasure from the substance and less from more healthy experiences.
- This includes prescription and over-the-counter medicines, vitamins, and herbal products.
Following a 3-week, open-label run-in period where the dose of MES-amphetamine XR was optimised to 10, 20 or 30 mg once a day, subjects were then randomised into a 3-way double-blind, placebo-controlled crossover trial. They received their optimal dose of MES-amphetamine XR, an equivalent dose of lisdexamfetamine in terms of d-amphetamine base, or placebo. On the primary and secondary efficacy variables of behaviour, attention amphetamine addiction and problem solving, lisdexamfetamine delivered equivalent or better efficacy than MES-amphetamine XR with both drugs being maximally effective at 2 h post-dose (Biederman et al., 2007a). However, on the problem-solving endpoints, it was also evident that lisdexamfetamine maintained its maximum effect for at least 12 h, whereas the effect of MES-amphetamine XR showed a clear decline after 6–8 h (Biederman et al., 2007a).
What Are the Side Effects of Amphetamines?
In reality, there is little abuse of these drugs by patients with ADHD (Merkel and Kuchibhatla, 2009), and in most cases the challenge for the prescribing doctor is to keep the patients taking their medication rather than limiting its use. Many teenage patients stop using despite the drugs having clear benefits for their school performance; they cite reasons such as feeling too controlled, wanting empowerment from medication, etc. The chemical structure, particularly the 3-dimensional (3-D) structure of amphetamine, is critical in determining the pharmacological effects that underpin its considerable therapeutic benefits and also its liability for recreational abuse. Amphetamine belongs to the class of drugs called the ‘β-phenylethylamines’. This result shows that the subjective effects of lisdexamfetamine were not enhanced when the drug was given intravenously. Blood pressure measurements are useful objective measures of the PD effects of sympathomimetic drugs.
Clinical implications
Both isomers of amphetamine dose-dependently increased the extracellular concentrations of noradrenaline in the prefrontal cortex (PFC) and dopamine in the striatum. When comparing the effects of drugs on the efflux of catecholamines in the PFC it is important to take into account the highly unusual neuroanatomy of this brain region. The density of DAT sites on PFC dopaminergic neurones is very low (Hitri et al., 1991), and as a consequence, most dopamine that is released is sequestered via NET into noradrenergic neurones (Mazei et al., 2002; Morón et al., 2002; Stahl, 2003). Since then, it has transformed from a drug that was freely available without prescription as a panacea for a broad range of disorders into a highly restricted Controlled Drug with therapeutic applications restricted to attention deficit hyperactivity disorder (ADHD) and narcolepsy. This review describes the relationship between chemical structure and pharmacology of amphetamine and its congeners.

- It’s also dangerous to combine meth with other stimulants, like cocaine.
- During periods of non-use, the user may recall the feeling of euphoria produced by the drug and desire to take it again.
- This is not the same as substance dependency — the physical symptoms of tolerance and withdrawal.
- Although there is no definitive information on the subject, the large molecular size and polar characteristics of lisdexamfetamine predict that the parent molecule is unlikely to cross the blood–brain barrier.
- Addiction means that cravings and compulsive use of the drug become very important to a person.
Can amphetamines treat ADHD in children?
You don’t have to live with addiction, and it’s never too late to get help. If you or someone you love are struggling with Adderall addiction or addiction to other amphetamines or stimulants, American Addiction Centers (AAC) is here to help. With the right support, many people who have experienced SUD go on to live happy lives with strong relationships and https://ecosoberhouse.com/ positive health outcomes. A person can take a long time to adjust to life without substance use. A person may take years to be able to manage without the substance, and they may return to using a substance for some periods of time. Treatment may be long-term and may involve periods of difficulty as a person adjusts to their life without substance use.
- Meth produces more reward chemicals than your brain can fully handle.
- Many teenage patients stop using despite the drugs having clear benefits for their school performance; they cite reasons such as feeling too controlled, wanting empowerment from medication, etc.
- If your health care provider prescribes a drug with the potential for addiction, use care when taking the drug and follow instructions.
- What is also evident from the data in Figure 6 is that the magnitude of increases in systolic and diastolic blood pressures was not statistically different after oral or intravenous administration of lisdexamfetamine.
Methamphetamine, or meth, is a powerful stimulant that can make you feel more awake and active. There is also a clear pattern of high dosage and daily usage correlating with higher risks of substance-induced psychosis. Amphetamines impair the cognitive thought process and subsequently precede acute psychosis. This suggests that continued impairment due to amphetamine use is a precursor to psychosis.
What forms do amphetamines come in?
Seeking amphetamine addiction rehabilitation is an important step toward taking back control of your life and starting the process of recovery. It’s important to have an individualized addiction treatment plan that is based on a proper assessment by treatment professionals.14 This helps determine the appropriate level of care based on your needs and the severity of your addiction. No tests can determine drug misuse or addiction, but a medical professional can discuss a person’s substance use with them and assess possible risk factors that support the possibility. When you spend time with a loved one or eat a delicious meal, your body releases a chemical called dopamine, which makes you feel pleasure. It becomes a cycle — you seek out these experiences because they reward you with good feelings. To diagnose amphetamine toxicity, other toxicities need to be explored, including toxicities to cocaine, methylxanthine, phencyclidine, and other sympathomimetics.
Help us change mental health care forever.
- Amphetamines reduce hunger and increase breathing, heart rate and blood pressure.
- Methamphetamine has a much longer duration of action and a larger percentage of the drug remains unchanged in the body.
- Lisdexamfetamine, a long-acting amphetamine medication, is FDA-approved for the treatment of a binge-eating disorder.
