||This article may require cleanup to meet Wikipedia's quality standards. The specific problem is: The article is misleading in its implication that in vitro pharmacology and/or animal study supports the claims of effects in humans. This is original research unless reliable sources making those connections can be produced. The article suggests that there are benefits for healthy individuals, but the only clinical study referenced relates to brain damaged subjects.. (September 2014)|

Phenylpiracetam (Phenotropil, Carphedon) is a phenylated analog of the nootropic drug piracetam which was developed in 1983 in Russia where it is available as a prescription drug. It has been used in humans as a central nervous system stimulant, a locomotor stimulant, a sports performance enhancer, and a nootropic. Research on animals has shown phenylpiracetam to have various actions such as anti-amnesic, antidepressant, anticonvulsant, antipsychotic, anxiolytic, and memory enhancement effects.
A small number of low-scale clinical studies have shown possible links between prescription of phenylpiracetam and improvement in a number of encephalopathic conditions, including lesions of cerebral blood pathways, traumatic brain injury and certain types of glioma.
Phenylpiracetam reverses the depressant effects of the benzodiazepine diazepam, increases operant behavior, inhibits post-rotational nystagmus, prevents retrograde amnesia, and has anticonvulsant properties.
In Wistar rats with gravitational cerebral ischemia, Phenylpiracetam reduced the extent of neuralgic deficiency manifestations, retained the locomotor, research, and memory functions, increased the survival rate, and lead to the favoring of local cerebral flow restoration upon the occlusion of carotid arteries to a greater extent than did piracetam.
Phenylpiracetam has recently gained niche popularity from online nootropics suppliers in the US and other countries outside of Russia. Given its lack of abuse potential,[medical citation needed] phenylpiracetam is not scheduled by the DEA.
Because it increases physical stamina and provides improved tolerance to cold weather, it appears on the lists of banned substances issued by the World Anti-Doping Agency. This list is applicable in all Olympic sports.
