What are Racetams?
Racetams are cognitive enhancers also known as nootropics. Piracetam is the “original” racetam. It is the least potent although still highly recommended, especially for those just beginning to experiment with the racetam family.
Since the discovery of piracetam, several more potent and arguably more effective derivatives have been created. Each one varies slightly in its mode of action and the exact mechanisms of how each racetam works is not completely understood. Much of what we know about the racetam comes from animal studies.
Unfortunately, there appears to be little research on young, cognitively healthy volunteers.
There is, however, research on the elderly, demented, schizophrenic, and those suffering from neurodegeneration caused by head trauma, stroke, and alcoholism.
This article is an attempt to let you see BOTH user reported effects (what is found colloquially on the internet) alongside published research. The racetams are NOT ranked.
1) Aniracetam and the Brain
Aniracetam is able to alleviate memory damage and learning impairments due to various traumas .
2) Oxiracetam and the Brain
In 60 elderly patients with mental disorders, oxiracetam exhibited more statistically significant improvement in “the memory factor” .
In animals, oxiracetam increases long-term potentiation (LTP) in the hippocampus, similar to aniracetam .
Oxiracetam (100 mg/kg) given immediately after a learning experience ‘post-trial’ can effectively facilitate the formation of long-term memory in mice detectable up to 4 months after dosing .
This study brings to light the fact that many nootropics, including oxiracetam, show evidence of memory retention after 16 – 24 hrs, which may explain the negative response in tests performed before this 24 hr window has lapsed .
Oxiracetam reduces drug-induced amnesia when given to mice 30 minutes before drug administration .
The same test performed in humans showed that oxiracetam improved overall test performances in drug-induced amnesia .
In mice, Oxiracetam improves scores in maze memory tests but appears to help only untrained mice .
Interestingly, improved performance was seen in doses of 25 mg/kg and 100 mg/kg but not at the midline 50 mg/kg mark .
Oxiracetam Can Prevent Neurodamage in Dementia
In patients with multiple forms of dementia, and those suffering from multiple strokes, 1,600 mg/kg Oxiracetam taken daily for 12 weeks significantly improved ‘quality of life’ as well as scores in neuropsychological tests .
Oxiracetam Can Prevent Neuron Damage from Chemical Exposure
Oxiracetam, as a pre-treatment to exposure, can prevent neuron damage from TBT (organotin trimethyltin) – a toxic biocide .
Oxiracetam may help with Energy Production
In test tubes, oxiracetam has been shown to increase the production of ATP .
Oxiracetam Does Not Effect Sleep Once Asleep
Oxiracetam significantly improved the performance in the offspring of mice when the mothers were supplemented with 50 mg/kg as a prenatal injection over control .
Oxiracetam and Nicotine has a Synergistic Effect
The combination of nicotine and oxiracetam have a synergy in learning tasks.
Nicotine and oxiracetam had a synergistic effect in mice tested in both passive and active avoidance tests (active test – are tests aligned for depressive symptoms. Passive tests – are a short and long term memory assessment) [25, 26].
The combination of the two drugs improved passive avoidance more than either drug separately, and in the active avoidance test, the combination (with low dose nicotine) showed improved effects never observed with nicotine alone .
Oxiracetam also prevented slight depressive behavior by mice when given high doses (1 mg/kg) of nicotine insomnia, drowsiness, and agitation . Because of piracetam’s anti-clotting abilities, there is an advisement to stay away from piracetam if already on blood thinning drugs. Headache, fatigue, foggy thinking are all symptoms of the racetams that you should either stop or have dosed too high.
Mechanism of Oxiracetam in the Brain
Oxiracetam increases signaling efficiency in hippocampal cells .
Oxiracetam is a positive modulator of AMPA sensitive glutamate receptors in neurons .
3) Pramiracetam and The Brain
Pramiracetam, similar to piracetam, has been tested in drug-induced amnesia studies.
In healthy volunteers, Pramiracetam has been shown to reduce drug-induced amnesia in both young and older subjects .
Studies also show that pre-administration of pramiracetam is also effective at suppressing drug-induced amnesia .
Pramiracetam increases exploratory activity in mice when dosed at 15mg/kg, and is suppressed at 60mg/kg with the middle range 30mg/kg having no effect .
Pramiracetam has been shown to increase cognitive abilities and memory in young men suffering from head trauma. This improvement was maintained even after pramiracetam was discontinued .
Pramiracetam significantly improves objective memory in non-depressed, non-demented healthy elderly .
In healthy elderly with memory loss, supplementation with pramiracetam proved more beneficial than memory training .
4) Phenylpiracetam and The Brain
Phenylpiracetam is thought to cross the blood-brain barrier because of the additional phenyl group, although there is no research to validate this.
Phenylpiracetam Helps in brain injuries, stroke, and epilepsy.
Phenylpiracetam daily for one year was able to improve both functional and cognitive parameters in stroke patients (dose was 400 mg) .
Phenylpiracetam dosed 200 mg improved both neurological and psychological symptoms over the control group in individuals with diseases of the brain .
Epilepsy patients dosed with 100 mg 2x/day phenylpiracetam improved by 12% in cognitive performance tests .
In individuals suffering from diseases of the brain (brain tumors or natural lesions), 200mg phenylpiracetam showed improvements in cognitive decline .
Anxiety and Depression
In individuals suffering from diseases of the brain (brain tumors or natural lesions), 200 mg daily phenylpiracetam resulted in improvements in depression and anxiety .
A Comparison of the Most Well Known Racetams

How to Use Racetams
Aniracetam: 100 mg – 1,500 mg/day. Average dose 750 mg 3 X per day.
Aniracetam is rapidly absorbed and seems to be quickly metabolized by the body, making dosing throughout the day more beneficial .
It also appears to be taken up in fasted states although it is fat soluble.
Typical dosage seems to be in the 100 – 1,500 mg range.
Oxiracetam: 1,200 – 2,400 mg
Supplementation of oxiracetam tends to be in the dosage range of 1,200 – 2,400 mg taken over the course of a day, either in two to three evenly spread dosing periods (such as three doses of 400 mg or 800 mg).
Oxiracetam seems to be about as strong as Aniracetam. However, Oxiracetam is more bioavailable and therefore stays in the body longer, so you don’t have to take it as often. Oxiracetam’s bioavailability ranges from 68 to 82 percent .
Pramiracetam: 1,200 mg/day
Currently, the evidence using pramiracetam in humans uses either 400 mg 3 x/day, or 600 mg 2 x/day.
Phenylpiracetam: 200 – 600 mg/day
Phenylpiracetam is taken at a dosage of 100 – 200 mg at high doses. It is recommended to start with 50 mg first.
The dose of 100 – 200 mg/day is usually dived throughout the day totaling somewhere between 200 – 600 mg/day.
Effects on Acetylcholine
While both oxiracetam and aniracetam (100 mg/kg) didn’t modify choline concentrations in any tested brain region, they did slow a scopolamine drug-induced decrease of acetylcholine. Oxiracetam did so in the hippocampus and cortex (but not striatum) at doses of 50 and 100mg/kg. Higher and lower doses were ineffective. Aniracetam (100 and 300 mg/kg) reduced acetylcholine decrease in the hippocampus only .
Independent of increasing acetylcholine concentrations, oxiracetam appears to increase acetylcholine utilization in the cortex and hippocampus at 100 – 300 mg/kg injections .
Repeated daily doses of oxiracetam were noted to increase acetylcholine utilization by 31% relative to the control, and appears to be more potent and prolonged than Piracetam .
Injections of both piracetam and oxiracetam increase choline uptake in the hippocampus .
Those who have had their adrenals removed will not have the benefit from Piracetam’s effects .
Oxiracetam does not impair sleep quality, although it may prolong the ability to actually fall asleep which is dose-dependent .
Although Aniracetam is known to reduce depression, it has been shown ineffective in reducing depression in younger mice .
Phenylpiracetam is excitatory and may disturb your sleep.
