title: Behavioral effects of diazepam and propranolol in patients with panic disorder and agoraphobia.
abstract: The effects of oral doses of diazepam (single dose of 10 mg and a median dose of 30 mg/day for 2 weeks) and propranolol (single dose of 80 mg and a median dose of 240 mg/day for 2 weeks) on psychological performance of patients with panic disorders and agoraphobia were investigated in a double-blind, randomized and crossover design. Both drugs impaired immediate free recall but the decrease was greater for diazepam than propranolol. Delayed free recall was also impaired but the two drugs did not differ. Patients tapped faster after propranolol than diazepam and they were more sedated after diazepam than propranolol. After 2 weeks of treatment, patients tested 5-8 h after the last dose of medication did not show any decrement of performance. These results are similar to those previously found in healthy subjects. Accumulation of drugs was not reflected in prolonged behavioral impairment.
