Twenty healthy male volunteers (aged 18–35 years) participated in a five-way double-blind crossover design. The latter was included as an internal control for demonstrating sensitivity of the method. The ephone tests were clearly less sensitive than the standard test, though sufficient for showing significant effects of alprazolam 1 mg and lorazepam 2 mg. A secondary purpose was to compare the sensitivity of newly developed ephone tests with a standard laboratory test of memory. Alprazolam had clear dose-dependent effects on different aspects of memory: 0.25 mg did not affect any parameter; 0.5 mg impaired performance in a Word Learning Test and a Spatial Memory Test and also psychomotor performance; 1.0 mg additionally impaired Syntactic Reasoning, Semantic Verification, and Critical Flicker Fusion performance. Lorazepam significantly impaired all performance measures except two: verbal fluency and accuracy of music recognition were insensitive to drug effects. Alprazolam's effects were not selective for any of the cognitive functions as measured in this study. Treatments were single oral doses of alprazolam (0.25, 0.5 and 1.0 mg), placebo and lorazepam 2.0 mg. This study was designed to confirm the hypothetical dose-dependent effect of alprazolam on memory and to compare its effects on tests measuring different aspects of cognitive and psychomotor functioning.

In a double-blind trial of 4 weeks' duration one group (28 patients) received alprazolam 0.75-3 mg/day and the other (30 patients) received lorazepam 3-12 mg/day. Fewer side effects were reported in the alprazolam treatment group, with the mental confusion symptom occurring significantly less often. 58 patients suffering from anxiety neurosis were divided into two groups, matched for age, sex, marital status and symptomatology. However, there was no significant difference in measured anxiety levels between the two groups at any stage. Both groups showed a steady and significant reduction in anxiety levels as measured by Hamilton Anxiety Rating Scale and Clinical Global Impression scores at 0, 1, 2 and 4 weeks.
