[Therapy of sleeping disorders with l-tryptophane plus oxprenolol/a double-blind study (author's transl)].

38 psychiatric inpatients with various degrees of sleeping disorders were given L-tryptophane plus oxprenolol or placebo, each for two nights. Self-rating, rating of the nursing staff, tests of attention level and motor performance were the variables of the investigation. The statistical evaluation of the double-blind study shows no significant difference under these specific experimental conditions.
