Olracetam and cytarabine can be taken together to improve brain function. Olracetam is mainly used to treat memory loss or dementia caused by various reasons, such as stroke, traumatic brain injury or even cognitive dysfunction caused by Alzheimer’s disease. Cytarabine can improve brain function by stimulating brain metabolism, and is commonly used for impaired consciousness caused by stroke, traumatic brain injury, encephalitis and other causes. It is also useful for post-stroke symptoms and tinnitus. Olracetam may have adverse reactions such as mental excitement, insomnia, and nausea. Cytarabine may cause adverse reactions such as nausea, vomiting, dizziness, insomnia, and panic. Whether or not you need to use both medications to treat various declines in brain function requires a visit to the hospital, where your doctor will decide based on your condition, and you should not use the medications without authorization.
