654-2 drug is not the main drug for the treatment of vertigo, 654-2 is also known as eliminated scopolamine, the main effect is to relieve smooth muscle spasm, which smooth muscle includes smooth muscle spasm of gastrointestinal tract, biliary tract, and also can be used for some patients with microcirculatory disorders, so for some vertigo can play a slight relief of dizziness symptoms. However, 654-2 is mainly used to relieve pain caused by smooth muscle spasm in clinical practice, and has obvious pain-relieving effects, such as some gastroenteritis or biliary tract diseases, where patients have severe abdominal pain, which can be controlled by applying 654-2. For vertigo clinically, including central vertigo and peripheral vertigo, the first step is to find the cause of vertigo. For peripheral vertigo, vestibular depressants, such as betahistine mesylate, can be given to patients appropriately. For central vertigo, the main focus is to improve microcirculation, so 654-2 is not a medicine for vertigo.
