Oxybral is a medical drug used to improve brain and nervous system functions. It is considered a common treatment prescribed to stimulate memory performance and concentration. This drug works primarily to enhance blood flow to the brain, which helps improve the oxygen and nutrients the brain needs to perform its functions more efficiently. Oxybral is used to treat some problems associated with poor concentration and mental awareness, especially in patients who suffer from blood flow disorders to the brain. It is also used in cases of cognitive decline associated with aging or various health conditions.
