Lorazepam and diazepam in the treatment of neurotic anxiety: a double-blind trial

Area of Science:

• Psychiatry
• Clinical Pharmacology

Background:

• Anxiety disorders are prevalent, necessitating effective pharmacological interventions.
• Benzodiazepines, including lorazepam and diazepam, are commonly prescribed for anxiety.
• Comparative efficacy and safety data are crucial for clinical decision-making.

Purpose of the Study:

• To compare the efficacy and safety of lorazepam versus diazepam in treating neurotic patients with intense anxiety.
• To evaluate patient response and investigator assessment of treatment outcomes.
• To determine the required dosage and incidence of side effects for each medication.

Main Methods:

• A double-blind, between-patients trial involving 58 neurotic patients with intense anxiety.
• Patients were randomized to receive either lorazepam or diazepam.
• Outcomes were assessed using global illness ratings, investigator judgments, and the Hamilton Anxiety Scale.

Main Results:

• Both lorazepam and diazepam demonstrated similar treatment outcomes and efficacy.
• Lorazepam showed a trend towards better outcomes in global illness ratings and investigator assessments.
• Lower doses of lorazepam were required, with fewer reported side effects and dropouts compared to diazepam.

Conclusions:

• Lorazepam and diazepam are similarly effective in managing intense anxiety.
• Lorazepam may offer a favorable side effect profile and lower dosage requirements.
• Further research could explore long-term efficacy and specific patient populations benefiting from each agent.
