What are the effects of gastrodin for injection?

　　The main effects of Gastrodin for Injection include relieving headache symptoms, improving dizziness, providing sedative and sleep-promoting effects, nourishing neural tissues, and assisting in the treatment of neuralgia. The specific analysis is as follows:

　　1. Relieving headache symptoms: This medication effectively alleviates various types of headaches, particularly tension-type headaches, migraines, and vascular-nerve-related headaches. By regulating cerebral blood vessel dilation and constriction, it reduces vascular spasms and relieves discomfort such as throbbing or stabbing head pain.

　　2. Improving dizziness: It shows good efficacy against vertigo caused by inner ear disorders or insufficient cerebral blood supply, helping to relieve symptoms including dizziness, blurred vision, rotational sensations, and nausea. By enhancing vestibular system function and cerebral circulation, it stabilizes signal transmission in the vestibular nerves and helps patients regain balance.

　　3. Sedative and sleep-promoting effects: It has a calming effect on patients with neurasthenia, insomnia, and vivid dreams. By modulating excitability of the central nervous system, it helps shorten sleep onset time and improve overall sleep quality. The drug does not cause residual effects such as next-day drowsiness or fatigue, making it suitable for individuals needing improved sleep.

　　4. Nourishing neural tissues: It promotes metabolism in nerve cells, enhances their tolerance to ischemia and hypoxia, and accelerates the repair of damaged neural tissue. It is commonly used as an adjunctive treatment for conditions such as peripheral neuritis and polyneuritis, helping to alleviate numbness and sensory abnormalities caused by nerve damage.

　　5. Assisting in neuralgia treatment: By inhibiting pathological pain signal transmission in nerves, it reduces pain severity in conditions such as trigeminal neuralgia and sciatica. When used in combination with other analgesics, it can enhance therapeutic effectiveness while reducing the dosage and adverse reactions associated with single-agent therapy.

　　This medication must be used strictly according to medical instructions, with dosage and treatment duration adjusted based on individual conditions. Patients should monitor for possible adverse reactions such as rash or dizziness during treatment. The drug should be stored sealed and protected from light to prevent changes in its properties that could affect therapeutic efficacy.
