Background. Previous studies showed that new coordinate compound Cerebrogerm (ferrum bis(citrato)germanate) is a promising cerebroprotector.
Objective of the study is a comparative analysis of the central stage of the pharmacokinetics of Cerebrogerm as well as its distribution in vital organs in cases of closed head injury.
Methods. On the experimental original model of closed brain injury in rats the parameters of the central stage of Cerebrogerm pharmacokinetics: the distribution in brain, liver, kidneys, were studied.
Results. It is established that, in cases of closed head injury Cerebrogerm reaches maximum concentration first in the brain (in 3.75 h), then in the kidneys (in 3.92 h), and finally in the liver (in 4.17 h). In this case, the magnitude of the Cmax of the coordinating compound of germanium that is being investigated in different biosubstrates of the rats with closed head injury may be presented in descending order as follows: brain (7.95 mg/L) > liver (6.22 mg/L) > kidneys (1.79 mg/L).
Conclusions. The compound Cerebrogerm studied easily gets through the blood-brain barrier and meets the present requirements for cerebroprotectors and antihypoxants. The attained results allow noting that in the early post-traumatic period of closed head injury, the blood circulation in the kidneys does not change and cannot modify the absorption-elimination processes of xenobiotics. It has been also established that Cerebrogerm is distributed faster in the examined organs in cases of closed head injury. The highest concentration of the drug is present in the brain and the smallest one – in the kidneys.
