Picamilon by Ray Sahelian, M.D.
Picamilon, also spelled pikamilon was made in 1969 by
the All-Union Scientific Research Institute. Picamilon is a derivative of
gamma-amino-butyric acid (GABA) and nicotinic acid, a B vitamin. Clinical use of
picamilon began in the mid 1980s.

[Gabaergic mechanism of cerebrovascular and
neuroprotective effects of afobazole and picamilon]
Eksp Klin Farmakol. 2005 Jan-Feb;68(1):20-4.
The role of GABAergic mechanisms in realization of the effects of afobazole and
picamilon on the cerebral circulation was studied in rats. It is found that the
cerebrovascular effect of afobazole significantly decreases on the background of
the GABA receptor antagonists bicuculline and picrotoxin. This is evidence of an
important role of the GABA system in the its cerebrovascular and neuroprotective
activity of afobazole. The results of experiments with picamilon showed that the
cerebrovascular effect of this drug is not affected by receptor blocking with
bicucullin. However, the blocking of chloride channels of the GABA receptors by
picrotoxin significantly decreased the effect of picamilon on the cerebral blood
flow.
[Effects of pikamilon on the brain water-electrolyte
balance and in models of responses to the noise and vibration exposure, and
their combination with Eksp Klin Farmakol. 2000 Sep-Oct;63(5):72-5. Pharmacology
Department, Simferopol State Medical University, Crimea, Ukraine.
Electric impedance measurements on awake rabbits with electrodes implanted into
cortex, thalamus, and hypothalamus showed that modeling of the noise and general
(wide-band) vibration, as well as their combination with sea-sickness action,
leads to disturbances in the aqueous-electrolyte balance in brain. This is
manifested by extracellular and (less pronounced) intracellular edema
development. Picamilon administration (10 mg/kg, i.v.) completely prevented
development of the vibration-induced intracellular edema and markedly reduced
the development of damage in all other cases studied.
[Correction of diabetic neuropathies using aldose
reductase inhibitors and pikamilon]
Vopr Med Khim. 1998 Nov-Dec;44(6):559-64. Institute of Biochemistry, Kiev.
Streptosotocin-induced diabetes in rats is accompanied by the development of
diabetic complications such as neuropathies. [2-14C] serotonin and [U-14C] GABA
release from the neurotransmitter pre-loaded synaptosomes showed significant
elevation. Aldose reductase inhibitors (AL-1576, sorbinil) administration leads
to partial restoration of serotonin and GABA release, while picamilon restored
only GABA release. It was shown that Na+,K(+)-ATPase activities decreased in
synaptosomes, synaptic membranes and sciatic nerve of diabetic rats compared to
control. Administration of AL-1576 normalized Na+, K(+)-ATPase activity, while
sorbinil and picamilon less effectively. Sorbitol level are increased in
streptozotocin-diabetic rats as compared to control. The picamilon and aldose
reductase inhibitors administration to diabetic rats is accompanied by the
partial reduction of brain sorbitol level. The findings confirm the important
role of picamilon and aldose reductase inhibitors in the prevention and
treatment of diabetic neuropathy.
Piracetam emails
Q. Does your research group have more information about Picamilon and
Piracetam? Do you think
they will enhance cognition?
A. It appears that piracetam does have a role to play in cognition.
Q. Have you looked into Picamilon and it's mood
altering properties?
A. Picalmilon appears to be a combination of GABA and nicotinic
acid. We have not evaluated this medicine in terms of cognition or its effect on
mood..
