The market for nootropics, or 'smart drugs,' saw US sales surpass $640 million in 2015 alone. A key question in this industry is: what is the drug piracetam used for? This synthetic compound was the first substance to be labeled a nootropic and is explored for both medical and cognitive-enhancing purposes.

Quick Summary

Piracetam is a synthetic compound used in some countries to treat conditions like muscle spasms and cognitive decline. It's also popular for off-label use as a cognitive enhancer, though its legal status and efficacy remain debated.

Key Points

Primary Use: In countries where it is a prescription drug, like the UK, piracetam is mainly used to treat cortical myoclonus (involuntary muscle spasms).
Nootropic Application: Its most common off-label use is as a cognitive enhancer, or 'smart drug,' to improve memory, learning, and focus, though evidence is mixed.
Mechanism: Piracetam is thought to work by improving cell membrane fluidity, modulating neurotransmitters like acetylcholine, and increasing blood flow in the brain.
US Legal Status: Piracetam is not approved by the FDA for any medical use and cannot be legally sold as a dietary supplement in the United States.
European Legal Status: In many European countries, piracetam is a prescription-only medication, though some nations allow over-the-counter sales.
Safety Profile: It is generally well-tolerated, but potential side effects include agitation, anxiety, insomnia, and weight gain. It should be avoided by those with kidney problems or on blood thinners.
Efficacy Debate: While some studies show benefits for cognitive decline and dyslexia, major reviews find the evidence inconsistent or insufficient to recommend its use for dementia.

The Origins and Nature of Piracetam

Piracetam is a synthetic substance first developed in the 1950s by Romanian chemist Corneliu E. Giurgea. It is a cyclic derivative of the neurotransmitter GABA (gamma-aminobutyric acid), although its mechanism of action is different. Piracetam was the first drug to be classified as a "nootropic," a term Giurgea coined to describe substances that could enhance cognitive functions like memory and learning without causing sedation or stimulation. It belongs to a class of drugs known as racetams, which all share a common 2-pyrrolidone nucleus in their chemical structure. Other drugs in this class include aniracetam, oxiracetam, and the anticonvulsant levetiracetam.

Unraveling the Mechanism of Action

The precise way piracetam works is still not fully understood, but research points to several potential mechanisms. It does not seem to function like its parent molecule, GABA. Instead, studies suggest it has a multi-faceted impact on the brain:

Membrane Fluidity: Piracetam is believed to restore or enhance the fluidity of cell membranes, particularly in the brain. By interacting with the polar heads of the phospholipid layer, it may improve membrane stability and function, making it easier for cells to send and receive signals.
Neurotransmitter Modulation: The drug appears to augment the effects of the neurotransmitter acetylcholine via muscarinic cholinergic receptors, which are crucial for memory processes. It may also influence NMDA glutamate receptors, which are involved in learning and memory.
Improved Cerebral Blood Flow: Piracetam can improve microcirculation in the brain. It does this by reducing the adhesion of red blood cells to blood vessel walls and decreasing platelet aggregation, which helps improve blood flow and oxygen consumption in the brain.
Enhanced Mitochondrial Function: Some research indicates that piracetam can improve the function of mitochondria, the energy-producing centers of cells. This may lead to enhanced ATP (energy) production and neuroprotective effects.

What is the Drug Piracetam Used For?

Piracetam is used for a variety of medical and off-label purposes, although the evidence supporting its efficacy is mixed and often based on older or small-scale studies.

Medical and Prescription Uses

In several European countries, piracetam is an approved prescription medication. In the United Kingdom, it is primarily prescribed to treat cortical myoclonus, a condition characterized by sudden, involuntary muscle spasms. It is often used in combination with other anti-myoclonic therapies. Studies have shown that piracetam can help reduce the severity of these seizures and improve patients' ability to perform daily activities when used at appropriate dosages.

Other prescribed or investigated uses in some regions include:

Vertigo
Cognitive disorders following cerebrovascular or traumatic events
Dyslexia in children
Sickle cell anemia, due to its effects on red blood cell deformability

Off-Label Use for Cognitive Enhancement

The most popular off-label use of piracetam is as a nootropic to boost brain function in healthy individuals. Users take it to improve memory, learning speed, focus, and overall mental clarity. Some small, older human trials have shown promise. For example, one study on healthy adults found that taking piracetam led to significant improvements in verbal learning. Another meta-analysis suggested it could have benefits for cognitive function in older adults with cognitive impairment.

However, the overall evidence remains inconclusive. A Cochrane review concluded there was not enough positive or consistent evidence to support its use for dementia or cognitive impairment. Many studies are considered low-quality or are dated, highlighting the need for more modern research.

Regulatory Status: A Global Divide

The legality of piracetam varies significantly around the world.

United States: The U.S. Food and Drug Administration (FDA) has not approved piracetam for any medical use. Furthermore, the FDA has explicitly stated that piracetam is not a legal dietary ingredient and cannot be marketed as a dietary supplement. Despite this, it is often found in cognitive enhancement supplements sold online. It is not a controlled substance, meaning possession is legal, but selling it for consumption is unlawful.
United Kingdom and Europe: In the UK and many other European countries, piracetam is a prescription-only medication (POM). In some countries like the Czech Republic and Hungary, it is available over-the-counter.
Other Regions: Canada does not allow the sale of piracetam but permits personal importation. In Australia, it is a prescription-only substance.

Potential Side Effects and Safety

Piracetam is generally considered well-tolerated, even when used at dosages explored in clinical studies. However, some users may experience side effects, which commonly include:

Hyperactivity or agitation
Nervousness or anxiety
Insomnia or drowsiness
Weight gain
Diarrhea
Depression

Due to its potential to slow blood clotting, it should be stopped at least two weeks before surgery and used with caution by anyone with a bleeding disorder or taking anticoagulant medications like warfarin. It is not recommended for pregnant women or individuals with severe kidney problems, as the substance is cleared by the kidneys.

Conclusion

So, what is the drug piracetam used for? The answer is complex and depends on where you are in the world. In some regions, it is a prescription medication for specific conditions like myoclonus. Globally, it is widely known and used off-label as a cognitive enhancer, a practice supported by anecdotal reports and some limited, dated scientific studies. However, it is not approved by the FDA in the United States and its sale as a supplement is illegal. While generally regarded as safe, the mixed evidence for its efficacy means that individuals should exercise caution, consult with a healthcare professional, and be aware of its legal status before considering its use.
