Sample Use Guides

In Vivo Use Guide
For adult persons and children it is recommended to use internally, after meal. Usually it is recommended to use 1 tablet (10 mg) trice per day. The maximum daily dose is 60 mg. The period of therapy is 2-4 weeks. According to doctor prescription it is possible to prolong the period up to 3 months.
Route of Administration: Oral
Experiments on immortalized hippocampal cell culture of mice showed that afobazole increases the NGF level in a final concentration of 10(-8) M and the BDNF level in final concentrations from 10(-8) to 10(-5) M.
