What is Coluracetam (135463-81-9)?

Raw Coluracetam powder (MKC-231) is a synthetic racetam drug purported to be a nootropic compound. It does not have a large body of evidence investigating it, but the mechanisms of action (as well as structute) appear to be very distinct from other racetam compounds like Piracetam or Aniracetam.

Raw Coluracetam powder appears to interact with a process known as high affinity choline uptake (HACU for short), which is the rate-limiting step of drawing choline into a neuron for synthesis into the neurotransmitter acetylcholine. Increasing the HACU rate appears to increase the activity of cholinergic neurons, so it is a desired target for cognitive enhancement.

Coluracetam (135463-81-9) uses

Coluracetam (INN) (code name BCI-540; formerly MKC-231) powder is a nootropic agent of the racetam family. It was initially developed and tested by the Mitsubishi Tanabe Pharma Corporation for Alzheimer’s disease. After the drug failed to reach endpoints in its clinical trials it was in-licensed by BrainCells Inc for investigations into major depressive disorder (MDD), which was preceded by being awarded a “Qualifying Therapeutic Discovery Program Grant” by the state of California.


Coluracetam (135463-81-9) Dosage

Most of the research on coluracetam was done on animals rather than humans, so there are no universally accepted dosing guidelines. The active dosage range is generally described as 5–20 mg. Users of coluracetam have reported a wide range of doses administered both orally and sublingually.

User feedback has also mentioned that tolerance to coluracetam powder can develop quickly. As with all medications, especially nootropics, it’s best to start at smaller doses and up the dose gradually as your body reacts and adjusts to the medication. Coluracetam is non-toxic and is considered to be well-tolerated and safe.
