Clobazam. A 1.5 benzodiazepine derivative: effects upon human psychomotor performance under different levels of task reinforcement.

Two dose levels of clobazam, a benzodiazepine derivative, were compared to placebo for their effects upon psychomotor performance in an acute dose daytime study with normals. An acute dose of 10 mg clobazam significantly reduced response latencies in the low reinforcement condition of a psychomotor performance task but not in the high reinforcement condition. However 20 mg clobazam did not produce any significant changes in performance under either low or high reinforcement. Response speed changes generally correlated positively with trait anziety and neuroticism scores at both doses of clobazam.
