Death may result when GABAergic substances are combined with other depressants such as opiates, benzodiazepines, barbiturates, gabapentinoids, thienodiazepines or alcohol.[1]

It is strongly discouraged to combine these substances, particularly in common to heavy doses.

Picamilon 20 mg from Russia

N-nicotinoyl-GABA, also known as Picamilon (Russian: Пикамилон), is a synthetic compound made of GABA and niacin (vitamin B3) used in the treatment of anxiety disorders or as part of a nootropic stack.

GABA is a neurotransmitter with relaxing and anti-anxiety effects. Niacin is a vitamin involved in DNA repair, fat and cholesterol synthesis, and widening of blood vessels. When taken as an oral supplement by itself GABA is not able to cross the blood-brain barrier (only a small amount does). However, picamilon (GABA bound to niacin) is able to cross the blood-brain barrier.[2]

Picamilon was developed in the Soviet Union in 1969 and further studied in both Russia and Japan as a prodrug of GABA.

History and culture

Picamilon was first developed in the Soviet Union in the late 1960s and has been sold as a prescription drug for anxiety in Russia since the 1980s.

In October, 2015 the Oregon Attorney General filed a lawsuit against US supplement mega-retailer GNC for selling products containing picamilon, claiming that GNC was knowingly violating the law. GNC countered that it had received no direct notice from the FDA on the ban and only learned of the FDA’s ruling on picamilon after the suit was filed. GNC stopped selling products containing picamilon, but the publicity created by the lawsuit sent GNC’s stock prices plunging and stockholders filed a class action suit against the company.

A month after the Oregon lawsuit was filed, Montana Senator Claire McCaskill of the Senate Special Committee on Aging wrote directly to major retailers, asking them to voluntarily remove products containing picamilon. She said she did so because of the FDA’s failure to respond to her repeated requests to take action, and because the agency remained silent on whether products containing picamilon should be recalled or removed from sale.[3]

Chemistry

Picamilon is a synthetic combination of GABA and niacin.

Pharmacology

Picamilon’s ability to cross the blood-brain barrier (BBB) is mostly due to the ability of niacin to widen blood vessels. Once picamilon enters the brain, the molecule is broken down by water into GABA and niacin.[2]

Once in the brain, GABA activates GABA (both GABAA and GABAB) receptors potentially producing an relaxing and anti-anxiety effect[4], while niacin increases blood flow to the brain by dilating blood vessels. This additional blood flow to the brain is thought to provide the neuroprotective and nootropic benefits of picamilon. New blood coming into the brain brings fresh oxygen, enhances the delivery and absorption of glucose and other nutrients, which may increase alertness and overall brain energy.[5]

Studies have shown combination of niacin and GABA affect the regulation of neurotransmitters in the brain. Picamilon was shown in one study on Parkinson’s disease to normalize serotonin and dopamine content, and dopamine uptake in the brain.[6]

Subjective effects

The effects listed below are based upon the subjective effects index and personal experiences of PsychonautWiki contributors. These effects should be taken with a grain of salt and will rarely (if ever) occur all at once, but heavier doses will increase the chances of inducing a full range of effects. Likewise, adverse effects become much more likely on higher doses and may include serious injury or death.

Toxicity and harm potential

This toxicity and harm potential section is a stub.

As such, it may contain incomplete or even dangerously wrong information. You can help by expanding or correcting it.
We also recommend that you conduct independent research and use harm reduction practices when using this substance.

Picamilon has a low toxicity relative to dose. Intake of extremaly high dose of picamilon every day may lead to hepatotoxicity.[9] Flushing of the face is the most common side effect. Flushing can result in burning, tingling, itching, and redness of the face, arms, and chest, as well as headaches. Picamilon potentially lethal when mixed with depressants like alcohol, benzodiazepines or opioids.

It is strongly recommended that one use harm reduction practices when using this substance.

Tolerance and addiction potential

The dependence potential for picamilon is unknown. There is currently no evidence to suggest that picamilon has addictive potential, but due to one of its mechanisms of actions (enhancing GABA signalling) it is still theoretically possible for picamilon to be somewhat addictive.

Tolerance will develop to the sedative-hypnotic effects within a couple of days of continuous use. After cessation, the tolerance returns to baseline in 7 - 14 days.

Picamilon produces cross-tolerance with all GABAgenic depressants, meaning that after its consumption, depressants will have a reduced effect.

Dangerous interactions

Legal status

Handcuffs-300px.png

This legality section is a stub.

As such, it may contain incomplete or wrong information. You can help by expanding it.

  • Russia: In Russia, picamilon is sold as a prescription drug.
  • United States: Selling picamilon or any product containing it as a dietary supplement is a violation of the FDA’s ruling, which makes it very difficult to find for purchase. At the same time, it is not a scheduled or controlled substance in the US and it is not illegal to posess or use.[citation needed]
