The most important and main injection for cerebral infarction patients in the acute stage is intravenous thrombolytic drugs, and the commonly used intravenous thrombolytic drugs are alteplase and urokinase. Alteplase is suitable for patients who are seen within 3-4.5 hours of the onset of the disease, and the dose is often 0.9 times the patient’s kilogram weight, while urokinase is suitable for patients who are seen within 6 hours of the onset of the disease. In addition, injections for nourishing brain cells such as piracetam and cytarabine can be given, while studies have shown that herbal injections such as ginkgo biloba, salvia, and thromboxane can play a role in improving brain circulation, which can help greatly in the recovery of cerebral infarction. Patients who have decreased immunity can take gammaglobulin to improve the immune function of the body.
