Adinazolam, a triazolobenzodiazepine that has an action similar to antidepressants in several pharmacological tests, was compared with amitriptyline and diazepam in endogenous depressive inpatients exhibiting dexamethasone suppression test non-suppression and/or abnormal contingent negative variation. Three parallel groups of 22 patients received in double-blind conditions either adinazolam (60-90 mg/day), amitriptyline (150-225 mg/day), or diazepam (30-45 mg/day) over a 4-week period, with weekly assessments by the Hamilton Rating Scale for Depression. Results showed significant superiority of amitriptyline over diazepam on total Hamilton depression scores. On the endogenomorphy subscale, amitriptyline induced significantly better improvement than both diazepam and adinazolam, whereas both amitriptyline and adinazolam exhibited significantly better antidepressant efficacy on the core symptoms of depression. Moreover, the dropout rate for inefficacy after 2 weeks of treatment was higher in the diazepam group. Taken together, these findings suggest that adinazolam has an antidepressant efficacy intermediate between amitriptyline and diazepam. Adinazolam was, however, much better tolerated than amitriptyline, and produced significantly fewer anticholinergic side effects.

Thirty outpatients between the ages of 60 and 85 with DSM-III Major Depression entered an 8 week randomized, double-blind comparison of desipramine and adinazolam mesylate, a triazolobenzodiazepine derivative. Outcome was assessed on several measures including the Hamilton Depression Rating Scale (HDRS), Montgomery-Asberg Rating Scale, Clinical Global Impressions (CGI), the 35-item Self-Rating Symptom Scale, and Carroll Depression Scale. Patients in both groups demonstrated a highly significant decrease in average HDRS scores (p less than 0.001) over the course of the study. Adinazolam was associated with significantly greater reduction in average HDRS scores by the third day. Repeated measures analysis of variance showed a significantly greater reduction in HDRS scores for adinazolam over the course of the study. The study medications were associated with distinct patterns of adverse reactions. Desipramine more often produced dry mouth, constipation and nervousness, while adinazolam was more likely to cause drowsiness and lightheadedness. Three of these elderly patients, all of whom were taking desipramine reported at least one fall during the study. Adinazolam may be a promising agent in the treatment of depression in the elderly.

In a 6-week, randomized, double-blind study, adinazolam mezylate (Deracyn Tablets, The Upjohn Company) was compared with placebo for the treatment of depression in 80 inpatients who met the criteria for single episode or recurrent DSM-III Major Depression. Subjects were admitted to the hospital 3 days before the start of the study and remained hospitalized for at least the first week of treatment. Efficacy was evaluated after 2, 4, 7, 14, 28, and 42 days of treatment. Adinazolam was significantly superior to placebo on all observer-rated and all global patient-rated measures of efficacy. Twenty-five subjects (63%) completed 6 weeks of adinazolam treatment and of these, 88% responded within 7 days. Only 15 placebo-treated subjects (38%) completed the study. Drowsiness and mild to moderate cognitive complaints were the only side effects observed more frequently with adinazolam, and both were transient. The results show that adinazolam is safe and more effective than placebo for the treatment of major depression.

Adinazolam, which is a 1-dimethylaminomethyl triazolobenzodiazepine, is an effective anxiolytic agent as defined by suppression of stress-induced increases in plasma corticosteroids. Adinazolam is also an effective antagonist of pentylenetetrazole. The 1-dimethylaminoethyl triazolo analog, U-43,465F, was inactive in the stressed rat test and only weakly active against pentylenetetrazole. Adinazolam and U-43,465F have been previously shown to have antidepressant activity in classical screening tests. They have also been found to potentiate the effect of norepinephrine and this is consistent with the activity of the known antidepressants; U-43,465F was found to be equieffective to imipramine in this test. Adinazolam was also effective; however, the magnitude of the potentiation was not as great. The uptake of norepinephrine was only weakly affected by either compound. Potentiation or uptake of serotonin were not significantly-altered pharmacological factors. Receptor binding studies were negative except at the benzodiazepine receptor. Chronic treatment with adinazolam did not decrease the number of beta-adrenergic receptors in the cerebral cortex of the rat, in contrast to the positive effect of imipramine. The discovery of triazolobenzodiazepines with antidepressant activity is of special interest. These agents will hopefully have lower toxicity than the tricyclic antidepressants and thus possess a more favourable therapeutic index. This would be advantageous in the treatment of depression.
