What is piracetam used for?

Official Answer by Drugs.com

Piracetam is a man-made substance, called a racetam, that was developed in the 1960s and originally used to treat motion sickness. It became the first drug to be labeled as a nootropic – which is a drug used to enhance memory, learning, and other cognitive functions. Piracetam was also found by serendipity to be an effective anticonvulsant in the 1980s.

Piracetam is not approved by the FDA for any medical or dietary use. In the UK, where it is available on prescription, it is mainly used for myoclonus. Proposed uses of piracetam include:

Piracetam has also been investigated for the following conditions, but more studies are needed to determine if it is beneficial for any of these conditions:

Animal studies have shown it can help reduce pain and inflammation by reducing the production of cytokines, and proinflammatory substances. It is not known if it has this effect in humans.

In general, evidence to support the use of piracetam for any condition is unclear. There possibly may be some cognitive benefits in older patients but not in those with dementia. In the United Kingdom, piracetam is available on prescription for myoclonus (involuntary spasmodic contraction of muscles), and may be used off-label for learning difficulties in children and cognitive deficits in the elderly.

How does piracetam work?

Piracetam is a racetam which is a man-made (chemically synthesized), derivative of gamma-aminobutyric acid (GABA). Experts are unsure exactly how piracetam works but research does suggest an effect on certain glutamate receptors, but not on GABA.

In addition, piracetam may influence membrane function and fluidity because it interacts with the polar heads in the phospholipid membrane, improving membrane stability and allowing the membrane to function normally with regards to transport of substances across the membrane, chemical secretion, and receptor binding and stimulation. This is thought to restore nerve transmission and provide neuroprotective and anticonvulsant effects.

Piracetam also improves the fluidity of platelet membranes and decreases the adhesion of red blood cells which improves blood flow through the brain and kidneys.

Is piracetam effective?

Most trials for piracetam were conducted years ago and did not use robust quality standards. Several Cochrane reviews have concluded that more evidence is needed. There may be some benefits for improving seizure or myoclonus frequency and also cognition in those who are aging, but not for those with dementia. There does not seem to be any benefit of piracetam for healthy people.

Who should not take piracetam?

Piracetam may not be suitable for people with severe kidney or liver disease, Huntington’s disease, or with bleeding conditions. It should not be taken by women who are pregnant or breastfeeding or by children unless under a doctor’s advice.

What are the side effects of piracetam?

Common side effects of piracetam include:

Piracetam may affect your ability to drive or operate machinery. Abrupt withdrawal of piracetam should be avoided.

What is the dosage of piracetam?

The standard dosage of piracetam for adults is 1.2grams to 4.8 grams per day depending on the condition:

When given for breath-holding spells in children, a dosage of 40-100mg per kilogram of body weight was used but you should always consult with a health professional before giving piracetam to children as it is not effective for many conditions.

Does piracetam interact with any other medications?

Piracetam may interact with anticoagulants, other medications that thin the blood, and thyroid supplements. Examples of medications it may interact with include:

Are there similar drugs to piracetam?

Since piracetam was developed in the 1960s, more than 20 piracetam-like substances have been developed for the purpose of improving cognitive function, treating cognitive impairment, or treating other nervous system disorders, although some are no longer available. These racetams are all man-made (chemically synthesized), derivatives of gamma-aminobutyric acid (GABA), and share a common structural feature, that of a 2-pyrrolidone nucleus. Experts are unsure how these substances work but research does suggest an effect on certain glutamate receptors, but not on GABA.

Levetiracetam is structurally like piracetam (it is also a racetam) but it is much more potent than piracetam as an anticonvulsant although its antidystonic effect (ability to control random muscle contractions) is similar to piracetam. It is marketed under the brand names Elepsia XR, Keppra, Keppra XR, Roweepra, Spritam, Roweepra XR in the U.S. as a treatment partial onset seizures, myoclonic seizures, and tonic-clonic seizures.

What are some brand names for piracetam?

Piracetam may also be known as:

Is piracetam illegal?

Piracetam is not illegal in the United States but because it is not regulated or approved by the FDA as a dietary supplement, it can technically only be sold for research purposes. However, despite the FDA rejecting piracetam as a dietary supplement, it can be still found as a dietary supplement, and remains available for purchase, despite warning letters from the FDA asking companies to stop marketing it. One study [Cohen PA, 2019] investigated 10 different over-the-counter piracetam supplements and found:

At least one law group [Kazerouni Law] is attempting to gather support for potential litigation against the manufacturers of piracetam, in an effort to get piracetam supplements off the street.

Is piracetam illegal in other countries?

Outside of the U.S., regulation of piracetam varies.

In Australia, piracetam requires a prescription to buy however up to 3 months can be imported from suppliers outside of Australia under a “Personal Importation Scheme”.

In Europe, the legal status of piracetam varies depending on the country. Some, such as the Czech Republic and Ukraine, do not require a prescription to buy piracetam. Others, such as Italy, Norway, and Spain do require a prescription.

In Canada, piracetam has no drug identification number (DIN) which means it cannot be sold but can be imported for personal use.

In Brazil, piracetam is readily available over the counter.

What is NAC and how can it benefit your health?

NAC (N-acetyl cysteine) is a supplement that may be used to help people replenish glutathione – the most powerful antioxidant in the body. Levels of glutathione rapidly deplete during oxidative stress or after acetaminophen overdosage. NAC may also be used to help improve fertility, brain health, heart health, and long-term respiratory conditions (such as Asthma or COPD) and reduce the risk of developing certain cancers. In medicine, NAC has been used as an antidote to acetaminophen overdose since the 1960s and to treat those with acute liver failure. Continue reading
