A comparative study of alpidem, a nonbenzodiazepine, and lorazepam in patients with nonpsychotic anxiety.

The use of benzodiazepines for generalized anxiety disorder (GAD) is a safe and effective treatment; however, their potential to produce dependence and impair psychomotor and cognitive functions is a drawback. In this study the efficacy and safety of alpidem, a nonbenzodiazepine, was assessed. Thirty patients who met DSM-III-R criteria for GAD were randomized to either alpidem (225 mg), lorazepam (4.5 mg), or placebo. The primary efficacy measure was the Hamilton Rating Scale for Anxiety (HAM-A). A repeated measures multivariate analysis of variance (MANOVA) was used to determine differences in HAM-A scores over time. The results showed a trend for alpidem to be more effective. Half of the alpidem group had a decrease of 50 percent or greater in their HAM-A scores with an almost equal effect on psychic and somatic symptoms. The most common side effects with alpidem and lorazepam were lightheadedness, drowsiness, and daytime tiredness. Moreover, treatment with alpidem did not manifest any withdrawal symptoms. Thus nonbenzodiazepine treatments are effective and safe for GAD.

The use of midazolam in acutely agitated psychiatric patients.

Agents currently used for acutely agitated patients such as sodium amytal and haloperidol are disadvantageous because of their adverse effects on the respiratory and extrapyramidal systems. Because of this, a rapid, safe, well-absorbed agent such as midazolam would be useful. This study compares the effectiveness of midazolam, sodium amytal, and haloperidol in agitated schizophrenic patients. Five male patients between 28 and 59 years were randomly assigned to each group. They were administered intramuscularly either 10 mg of haloperidol, 250 mg of sodium amytal, or 5 mg of midazolam. Over a 2-hour period, patients were rated for motor agitation, hostility, auditory hallucinations, and flight of ideas. Both midazolam and sodium amytal were significantly more effective than haloperidol in controlling motor agitation. There were no treatment differences on any other symptom rated. These results indicate that further studies on the use of midazolam to achieve rapid tranquilization would be useful.
