title: Alprazolam modifies animal behaviour on elevated plus-maze.
abstract: Exposure to elevated plus-maze is known to evoke approach-avoidance conflict behaviour and anxiety related movements in mice. Alprazolam (0.1 to 1 mg/kg, ip) produced dose dependant increase in antianxiety response, 100% first preference to open arm, open arm entries and exploratory behaviour. This effect was not only comparable to diazepam but also sensitive to reversal by flumazenil, a benzodiazepine receptor antagonist. Withdrawal of alprazolam (2 mg/kg/day for 14 days) and diazepam (20 mg/kg/day for 14 days) from chronic treatment produced typical anxiety response in animals. When tested for transfer latency, a parameter for learning and memory, both diazepam and alprazolam interfered with cognitive behaviour. Besides these actions, alprazolam also possesses anti-depressant property which makes it an atypical benzodiazepine for anxiety, panic disorder and endogenous depression.
