It is distributed in all bodies and fabrics, gets through GEB and a placental barrier. Selectively collects in tissues of a cerebral cortex, it is preferential in frontal, parietal and occipital lobes, in a cerebellum and basal gangliya.
T1/2 of plasma makes 4-5 h, of liquor - 6-8 h. It is removed by kidneys in not changed look. At a renal failure of T1/2 increases.

At simultaneous use of stimulators of TsNS strengthening of psychogogic action is possible.

At simultaneous use with neuroleptics strengthening of extrapyramidal disturbances is observed.
