RANDOMIZED CONTROLLED TRIAL |
Differential effects of alprazolam and buspirone upon acquisition, retention, and retrieval processes in memory

A group of 125 healthy young adults was given a memory battery 1 hour after
administration of alprazolam (0.5 and 1.0 mg), buspirone (5 and 10 mg), and
placebo under single-dose, double-blind conditions. On the wordlist recall
battery and a 24-hour retest, alprazolam appeared to impair acquisition and
retention in dosages of 1.0 mg; buspirone did not adversely affect test
performance at either dosage. On the basis of a 3-stage model of memory, a
neuroantomical/neurophysiological model is proposed to explain the
selective effects of the benzodiazepines on memory function.
