What are the efficacy, uses, and side effects of Lorazepam tablets?

Generally, Lorazepam tablets have functions and effects such as anti-anxiety, sedation and hypnotic action, anticonvulsant properties, muscle tension relief, and mitigation of acute alcohol withdrawal symptoms. Side effects include drowsiness, dizziness, memory impairment, dry mouth, and blurred vision. If necessary, this medication should be used according to medical advice. Detailed analysis is as follows:

I. Functions and Effects of Lorazepam Tablets

1. Anti-anxiety

Lorazepam tablets act on specific neurotransmitter systems in the brain, particularly binding to gamma-aminobutyric acid (GABA) receptors, enhancing the inhibitory effects of GABA. This effectively reduces or eliminates anxiety caused by various factors, helping patients feel calm and relieving symptoms such as nervousness and restlessness.

2. Sedation and Hypnotic Effect

By inhibiting the central nervous system, Lorazepam tablets reduce brain excitability, helping patients relax physically and mentally, inducing sleep, and improving sleep quality. They are especially suitable for patients with sleep disorders such as difficulty falling asleep, frequent dreams, and easy awakening.

3. Anticonvulsant

Lorazepam tablets can regulate neuronal excitability, stabilize cell membranes, and prevent the spread of abnormal discharges, effectively preventing and controlling seizures. They show good therapeutic effects on seizures caused by conditions such as epilepsy.

4. Relief of Muscle Tension

Lorazepam tablets act at the neuromuscular junction, inhibiting nerve impulse transmission, thereby reducing muscle tension, alleviating muscle spasms and stiffness. They are highly effective for tension-type headaches, neck and shoulder muscle tension, reducing muscle pain and discomfort for patients.

5. Relief of Acute Alcohol Withdrawal Symptoms

During alcohol withdrawal, patients may experience symptoms such as tremors and delirium. Lorazepam tablets can regulate nervous system disturbances, reduce these withdrawal symptoms, help patients pass through the withdrawal phase smoothly, and minimize physical damage caused by withdrawal reactions.

II. Side Effects of Lorazepam Tablets

1. Drowsiness

Lorazepam tablets inhibit the central nervous system, commonly causing patients to feel significantly drowsy and fatigued, with frequent daytime sleepiness, which can severely impact daily activities and work efficiency.

2. Dizziness

This medication may affect the balance function of the inner ear and cerebral blood circulation, causing patients to feel lightheaded and dizzy. Walking may lead to unsteadiness, increasing the risk of falls and injuries, especially in elderly or physically weak individuals.

3. Memory Impairment

Lorazepam tablets can affect the brain's memory function, potentially causing short-term memory loss. Patients may forget recent events or important tasks and information, impacting quality of life.

4. Dry Mouth

Lorazepam tablets may inhibit salivary gland secretion, reducing saliva in the mouth, causing dryness and discomfort of oral mucosa. This can affect taste and appetite and increase the risk of oral infections such as dental caries and mouth ulcers.

5. Blurred Vision

Lorazepam tablets may affect the eye muscle adjustment function and the nervous system's processing of visual signals, leading to blurred vision, which can interfere with normal visual activities such as reading, watching TV, and driving.

During the use of Lorazepam tablets, patients should avoid engaging in activities requiring high concentration and precise motor coordination, such as driving or operating machinery. Movements when standing up or walking should be slow, ensuring environmental safety to prevent falls due to dizziness or unsteady limbs.
