The duration of Cytophosphatidylcholine Sodium Tablets is related to the individual’s constitution, medical condition and drug resistance, so there will be some differences in the degree of absorption of the drug by the body. Doctors need to decide the discontinuation time according to the development of the patient’s condition after taking the drug, and there is no definite specific time. The main mechanism is to reduce vascular resistance and improve cerebral circulation to promote neurological recovery. Since choline is an important substance for nerve metabolism, it has a nerve-nourishing effect. Some patients with mild symptoms may be relieved or even cured by taking cytarabine sodium tablets orally for about 3 months, at which time the drug can be stopped. For some patients with more severe symptoms, the symptoms may still exist after 3 months of taking cytarabine sodium tablets, so they may need to continue taking them until their symptoms improve before they can stop. Therefore, patients need to take cytarabine sodium tablets strictly as prescribed by the doctor and eat light, easily digestible food such as millet porridge, egg custard, etc. Avoid cold, spicy and irritating food such as chili, hot pot and barbecue. In addition, if patients experience adverse reactions such as fever, nausea, diarrhea, drop in blood pressure, tachycardia, etc. while taking the drug, they need to stop the drug immediately and go to the hospital promptly. In addition, because Cytarabine Sodium Tablets is a nucleoside derivative that can increase blood flow, it should not be applied in large doses during acute cerebral hemorrhage.
