Lorazepam has central sedative medicinal properties and is used to treat anxiety disorders and relieve anxiety symptoms. Lorazepam is a benzodiazepine, and studies have found that a single high dose of lorazepam in healthy individuals can have a centrally sedating effect without affecting the respiratory and cardiovascular systems. Lorazepam is primarily used to treat anxiety and anxiety-related symptoms, but its use has the potential to exacerbate depressive symptoms in patients, so benzodiazepines should be used with caution in patients with primary depressive disorders or other psychiatric conditions. The use of benzodiazepines is associated with significant withdrawal symptoms and dependence, so short-term use is recommended. Medication may vary depending on the patient’s specific condition. Adverse effects of lorazepam are sedation, dizziness, fatigue, unsteady gait, in addition to fatigue, drowsiness, amnesia, disorientation, depression and other symptoms; lorazepam should not be engaged in the use of fine manipulation and driving, prohibited to the drug allergy and acute glaucoma patients to use this drug.
