Pipradrol (Meratran) is a mild central nervous system stimulant (norepinephrine-dopamine reuptake inhibitor) that is no longer widely used in most countries due to concerns about its abuse potential. [2] Pipradrol is still used in some European countries and in the United States, albeit rarely.

History

Pipradrol was patented in 1949, [3] and found use initially for treating obesity. [4] It was subsequently used for the treatment of a variety of other conditions such as narcolepsy, ADHD, and most particularly for counteracting the symptoms of senile dementia, this being the only application for which it is still used medically.[ medical citation needed ] Pipradrol proved useful for these applications as its relatively mild stimulant effects gave it a good safety profile compared to stronger stimulants.[ medical citation needed ] It was also studied as an adjutant treatment for depression and schizophrenia although it was never widely used for these purposes.

Pipradrol was made illegal in many countries in the late 1970s, at the same time as many other drugs which had a history of abuse. The relatively mild stimulant effects of pipradrol meant that it was scheduled under the less restrictive classes in most countries (i.e. Class C in United Kingdom and New Zealand) but was still considered of sufficient abuse potential to be made an illegal drug. It is now an obscure compound that is virtually unknown as an illicit drug of abuse, but is still used for some scientific research, often as a comparison drug for testing other stimulants against.

Dose

Dosage is between 0.5 and 4 milligrams per day, typically taken as a single dose in the morning as the long duration of effects of pipradrol (up to 12 hours) means insomnia can be a problem especially if it is used at higher doses or taken too late in the day.[ medical citation needed ]

Side effects

Common side effects include insomnia, anorexia, tachycardia, and anxiety. Rarer side effects include dry mouth, tremor, hypertension, euphoria, depression, and very rarely psychosis or convulsions.

<span class="mw-page-title-main">Stimulant</span> Overarching term covers many drugs that increase activity of the central nervous system

Stimulants is an overarching term that covers many drugs including those that increase the activity of the central nervous system and the body, drugs that are pleasurable and invigorating, or drugs that have sympathomimetic effects. Stimulants are widely used throughout the world as prescription medicines as well as without a prescription as performance-enhancing or recreational drugs. Among narcotics, stimulants produce a noticeable crash or comedown at the end of their effects. The most frequently prescribed stimulants as of 2013 were lisdexamfetamine (Vyvanse), methylphenidate (Ritalin), and amphetamine (Adderall). It was estimated in 2015 that the percentage of the world population that had used cocaine during a year was 0.4%. For the category "amphetamines and prescription stimulants" the value was 0.7%, and for MDMA 0.4%.

<span class="mw-page-title-main">Temazepam</span> Insomnia medication

Temazepam is a medication of the benzodiazepine class which is generally used to treat severe or debilitating insomnia. It is taken by mouth. Temazepam is rapidly absorbed, and significant hypnotic effects begin in less than 30 minutes and can last for up to eight hours. Many studies, some going as far back as the early 1980s out of Australia and the United Kingdom, both of which have had serious temazepam abuse epidemics and related mortality, have all mostly corroborated each other and proven that the potential for abuse and physical dependence is very high, even in comparison to many other benzodiazepines. As a result, prescriptions for hypnotics such as temazepam have seen a dramatic decrease since 2010, while anxiolytics such as alprazolam (Xanax), clonazepam, and lorazepam (Ativan) have increased or remained stable. Temazepam and similar hypnotics, such as triazolam (Halcion) are generally reserved for severe and debilitating insomnia. They have largely been replaced by z-drugs and atypical antidepressants as first line treatment for insomnia.

Triazolam, sold under the brand name Halcion among others, is a central nervous system (CNS) depressant tranquilizer of the triazolobenzodiazepine (TBZD) class, which are benzodiazepine (BZD) derivatives. It possesses pharmacological properties similar to those of other benzodiazepines, but it is generally only used as a sedative to treat severe insomnia. In addition to the hypnotic properties, triazolam's amnesic, anxiolytic, sedative, anticonvulsant, and muscle relaxant properties are pronounced as well.

<span class="mw-page-title-main">Sympathomimetic drug</span> Substance that mimics effects of catecholamines

Sympathomimetic drugs are stimulant compounds which mimic the effects of endogenous agonists of the sympathetic nervous system. Examples of sympathomimetic effects include increases in heart rate, force of cardiac contraction, and blood pressure. The primary endogenous agonists of the sympathetic nervous system are the catecholamines, which function as both neurotransmitters and hormones. Sympathomimetic drugs are used to treat cardiac arrest and low blood pressure, or even delay premature labor, among other things.

Butabarbital is a prescription barbiturate sleep aid and anxiety medication. Butabarbital has a particularly fast onset of effects and short duration of action compared to other barbiturates, which makes it useful for certain applications such as treating severe insomnia, relieving general anxiety and relieving anxiety before surgical procedures; however it is also relatively dangerous particularly when combined with alcohol, and so is now rarely used, although it is still prescribed in some Eastern European and South American countries. Its intermediate duration of action gives butabarbital an abuse potential slightly lower than secobarbital. Butabarbital can be hydrolyzed to Valnoctamide.

Stimulant use disorder is a type of substance use disorder where the use of stimulants caused clinically significant impairment or distress. It is defined in the DSM-5 as "the continued use of amphetamine-type substances, cocaine, or other stimulants leading to clinically significant impairment or distress, from mild to severe". These psychoactive drugs, known as stimulants, are among the most widely used drugs in the world today, although not all stimulants can induce addiction. As of 1993, Approximately 200 million Americans have used some type of stimulant in the past year alone.

<span class="mw-page-title-main">Mitragynine</span> Chemical compound

Mitragynine is an indole-based alkaloid and the most abundant active alkaloid in the Southeast Asian plant Mitragyna speciosa, commonly known as kratom. The total alkaloid concentration in dried leaves ranges from 0.5 to 1.5%. In Thai varieties, mitragynine is the most abundant component while 7-hydroxymitragynine is a minor constituent. In Malaysian kratom varieties, mitragynine is present at lower concentration. Such preparations are orally consumed and typically involve dried kratom leaves which are brewed into tea or ground and placed into capsules. Mitragynine consumption for medicinal and recreation purposes dates back centuries, although early use was primarily limited to Southeast Asian countries such as Indonesia and Thailand where the plant grows indigenously. Recently, mitragynine use has spread throughout Europe and the Americas as both a recreational and medicinal drug. While research into the effects of kratom have begun to emerge, investigations on the active compound mitragynine are less common.
