Picamilon (also known as nicotinoyl-GABA, Pycamilon, Pikamilon, etc) is a dietary supplement formed by combining niacin with GABA. It was developed in the Soviet Union in 1969 by the All-Union Vitamins Scientific Research Institute[1][2] and further studied in both Russia[3] and Japan as a prodrug of GABA.[4]
Picamilon is sold in the United States as a dietary supplement, while in Russia it is sold over the counter. The rights to the drug belong to pharmaceutical company NPK ECHO ("НПК ЭХО"), Moscow, Russia.

Mechanism of action and potential therapeutic applications
Picamilon is able to cross the blood-brain barrier[5] and then is hydrolyzed into GABA and niacin. The released GABA in theory would activate GABA receptors potentially producing an anxiolytic response.[6] The second released component, niacin acts as a strong vasodilator,[7] which might be useful for the treatment of migraine headaches.[8][9]
Medical use in Russia
In Russia, Picamilon is used for treatment of these illness.[10]
- Violations of cerebral blood flow (ischemic acute, subacute and rehabilitation period of ischemic stroke, chronic insufficiency of cerebral blood flow);
- Vasoneurosis;
- Asthenia;
- Depression;
- Senile psychosis;
- Alcohol (period of abstinence), acute alcohol intoxication;
- Migraine
- Craniocerebral trauma
- Neuroinfections;
- Primary open-angle glaucoma (for stabilization of visual function).
