Short-term sleep laboratory studies with cinolazepam in situational insomnia induced by traffic noise. In a double-blind, placebo-controlled sleep-laboratory study the short-term effects of cinolazepam--a recently introduced 1,4 benzodiazepine with a half-life of 9 h--on the all-night sleep, morning awakening and early morning behaviour were investigated in 20 young normal subjects, whose sleep was experimentally disturbed by nocturnal traffic noise. The latter was prerecorded on tape and reproduced by loud speakers throughout the night with a sound pressure level of 68-90 dB(A) (energy equivalent mean noise level LAeq: 79dB(A)). According to the parallel group design subjects received either a placebo or 40 mg cinolazepam. Specifically, they spent nine nights in the sleep laboratory: two adaptation
