Psychiatric patients (N = 26) were treated chronically (from 1 week to 12 years) with nitrazepam, because of insomnia. The patients gave their subjective estimations of the effects and side effects of nitrazepam. The concentrations of nitrazepam in the plasma were measured by 63Ni-EC-gas-liquid chromatography. The pharmacokinetics of nitrazepam were compared between the psychiatric patients and healthy volunteers (N = 11). The steady-state concentrations and the half-life of nitrazepam in the psychiatric patients were comparable to those of the healthy volunteers. The subjective hypnotic effect of nitrazepam was mostly good or satisfactory and remained unchanged during long-term treatment. Only a few, mild side effects were reported. Nitrazepam does not seem to cause enzyme induction with lowered plasma levels and may therefore be of special value in the treatment of chronic insomnia.

A comparative trial of nitrazepam, and triazolam (U-33,030) as pre-anaesthetic medicaments in patients allegedly not subject to insomnia, was undertaken the night before operation. The inclusion of placebo controls confirmed earlier findings that the majority of these patients suffer from transient insomnia. Nitrazepam and flurazepam are hypnotics, and in this study, triazolam also proved to be an hypnotic remarkably free of adverse effects.

Twenty-eight patients (12 M, 16 F) with insomnia were treated with nitrazepam 5 mg/d and oxazepam 25 mg/d, each for 11 days, in a double-blind crossover comparison with placebo. Half the patients received nitrazepam in the first drug period, and oxazepam in the second and the other half followed the contrary sequence. Both nitrazepam and oxazepam were found to be effective in inducing sleep and increasing sleep quality. No effects on dreaming or adverse effects were found. Nitrazepam did influence the frequency of awakening, but only in the second drug period. In the first period it reduced self-waking. It is concluded that both nitrazepam and oxazepam were effective in inducing sleep and in improving sleep quality.

The effects of 8-chloro-6-(2-fluorophenyl)-1-methyl-4H-imidazo[1,5-a] [1,4]benzodiazepine (midazolam, Ro 21-3981, Dormicum) in oral formulation of 15 and 30 mg on the sleep cycle of patients suffering from insomnia were assessed by means of polysomnographic recordings using a double-blind cross-over design. Both doses of midazolam were effective in improving sleep on short-term administration. In addition, significantly larger decrements of non-REM (NREM) sleep latency and of wake time through the 3rd third of night and nonsignificant trends toward smaller number of awakenings as well as shorter total wake time and longer NREM sleep time were induced by the 30 mg dose. Irrespective of the dosage sleep was almost exclusively increased at the expense of NREM sleep. Following 3 days treatment there was no rebound insomnia. These preliminary results suggest that the 15 mg dose could be appropriate in patients with difficulties in falling asleep, while the 30 mg dose would be more appropriate for patients who also experience difficulties in staying asleep.

Efficacy (sleep--sedation) and tolerance of 8-chloro-6-(2-fluorophenyl)-1-methyl-4H-imidazo[1,5-a][1,4]benzodiazepine (midazolam, Ro 21-3981, Dormicum) in a dosage of 10 mg to 30 mg p.o. were evaluated in a multi-center pilot study in 75 hospitalized patients, with an age range of 20 to 80 years. The patients suffered from mild to moderate insomnia, secondary to musculoskeletal disorders, peripheral nerve diseases and allergies. The optimal dose range was established on the basis of the relation between the degree of insomnia, age of the patients and the dose needed to obtain the optimal results for the sleep parameters. By this method it could be found that 10 mg was the optimal dose for patients over 60 years with mild to moderate insomnia; for patients less than 60 years old with moderate insomnia 15 mg to 20 mg midazolam was the optimal dose, and for patients with mild insomnia 10 mg was sufficient.

In a double-blind parallel study performed in 40 hospitalized patients, suffering from mild to moderate insomnia, the efficacy and tolerance of 15 mg of 8-chloro-6-(2-fluorophenyl)-1-methyl-4H-imidazo[1,5-a][1,4]benzodiazepine (midazolam, Ro 21-3981, Dormicum) administered p.o. were compared with those of 7-chloro-1,3-dihydro-3-hydroxy-5-phenyl-2H-1,4-benzodiazepin-2-one (oxazepam) in the same dosage. The results show comparable values for the two drugs but with significantly better results for midazolam in the parameters: time taken to fall asleep and number of nocturnal awakenings.

The hypnotic action and residual effects of a single bedtime dose of 8-chloro-6(2-fluorophenyl)-1-methyl-4H-imidazo[1,5-a][1,4]benzodiazepine (midazolam, Ro 21-3981, Dormicum) (7.5 or 15 mg) or 8-chloro-6(o-chlorophenyl)-1-methyl-4H-S-triazolo[4,3-a] [1,4]benzodiazepine (triazolam) (0.25 or 0.5 mg) were investigated in young, healthy adults. Motor activity was continuously recorded by a wrist-worn activity monitor. In comparison to placebo, all compounds reduced night-time motor activity in the first half, but not in the second half of the night. Subjects rated their sleep as more quiet. Neither the spontaneous daytime motor activity nor the self-rated state in the morning and at noon was affected by drug intake in the preceding night. Performance in the morning as measured by a psychomotor test was significantly impaired only after triazolam 0.5 mg. There was no evidence for rebound insomnia in the 3 nights following drug intake. The results indicate that midazolam 15 mg and triazolam 0.25 mg have a reliable hypnotic action without significant residual sequelae.

1. The efficacy of butoctamide hydrogen succinate (BAHS) was compared with that of nitrazepam on the basis of the polysomnograms and the subjective assessments. 2. Twelve healthy male students were divided into three groups consisting of 4 subjects each with were administered BAHS 600 mg, nitrazepam 5 mg, and BAHS 600 mg + nitrazepam 5 mg, respectively. 3. Polygraphic recordings were made for 8 consecutive nights for each subject, and the polysomnograms were evaluated by computerized automatic analysis using the interval histogram method. 4. An inert placebo was administered on the first 3 nights and on the seventh and eighth nights, and the test article regimen was administered on the fourth, fifth and sixth nights. 5. The test articles and the placebo were administered orally at 22:30 hr, and the recording of polysomnograms was started at 23:00 hr and ended at 8:00 hr the next morning. 6. The subjects were requested to fill out the subjective assessment of sleep before falling asleep and after arising the next morning. 7. BAHS increased REM sleep and decreased stage 2 sleep significantly; however, it failed to affect stage 1, 3 or 4 sleep. 8. Nitrazepam increased significantly the total sleep time and stage 2 sleep but decreased significantly the stage 3 sleep and decreased slightly the stages 1, 4 and REM sleep. 9. The combined treatment with BAHS and nitrazepam did not alter the sleep parameters except for increasing the total sleep time. 10. No obvious changes were observed in the subjective assessments after administration of the drugs. 11. These findings suggest that BAHS results in a unique sleep pattern different from benzodiazepines, and that BAHS may be suitable for treating insomnia in elderly patients and those with drug abuse, manic-depressive illness or schizophrenia.

In 60 insomnia patients placebo-controlled clinical examinations were performed with Dormicum hypnotic containing 15 mg midazolam active substance and made available by EGIS Pharmaceuticals. The patients involved in the study lived a normal life and belonged to both sexes. In the introduction the author summarizes the different forms of pathological sleep and discusses the pharmacology of some hypnotics on the basis of which a detailed, multifactorial, up-to-date clinical examination of a hypnotic should be planned. He uses up-to-date methods and means for the examination of the drug which meet the requirements of an adequate clinical testing of a hypnotic. The sleep disturbances of the patients have been classified and characterized by the author from the somnological aspects and with somnological methods. Patients with sleep onset, sleep maintenance, early morning, as well as mixed insomnias were differentiated. The effectivity of the drug was evaluated on the basis of data of sleep questionnaires referring to the target symptoms and the results of 24-hour polygraphic monitorings performed in 18 patients. In addition, the eventual hangover effect of the drug was assessed in these patients on the basis of the changes in reaction time, pulse rate, and skin resistance measured by polygraphy, besides placebo control on the day following the intake of the drug. The neurological and other organic side-effects were also examined and registered by means of the self-evaluating questionnaires, target specific interviewing of the patients, as well as by laboratory examinations. The drug proved to be most valuable as a hypnotic in patients with sleep onset and mixed insomnias. The hypnotic action was not so definite in sleep maintenance insomnias, the poorest responses were obtained in early morning insomnia cases. According to the results of polygraphic sleep examinations the two first sleep cycles become normal following the intake of the hypnotic. Parameters characteristic of REM sleep do not show changes. In the examined patients the number of side- and hangover effects attributable to the drug was very low. The author calls the attention to the importance of the observance of the dosage and administration of the drug which may prevent the development of a great number of side-effects. By giving a detailed description of a case history of an insomniac patient the author illustrates how the application field of midazolam may be further extended--within the frames of a sleep therapeutic process.

1. Peak saccade velocity provides a valuable means of assessing the sedative effect of drugs in humans. The present study investigated the effects of zolpidem, an imidazopyridine hypnotic, on saccade velocity in healthy volunteers after single and repeated administration. 2. Zolpidem 5 mg, 10 mg and 20 mg significantly and dose dependently depressed peak saccade velocity during the 1.5 h after a single administration. On the morning after zolpidem administration, peak saccade velocity had returned towards pretreatment levels. Nitrazepam 10 mg also significantly depressed peak saccade velocity but the effect was maintained the following morning. The saccade response to zolpidem (5 and 10 mg) was undiminished after the seven nightly doses. 3. Nightly administration of zolpidem improved subjective sleep quality and there was no evidence of rebound insomnia following cessation of drug treatment.
