Fluradoline and aspirin for orthopedic postoperative pain.
Fluradoline (150 or 300 mg), a novel tricyclic with both antidepressant and analgesic properties in animals, was compared with aspirin, 650 mg, and placebo when given orally for postoperative orthopedic pain in a double-blind, single-dose, parallel-group study. Analgesic measurements were made by two trained nurse observers using standard verbal rating and visual analogue scales. Aspirin was statistically superior to placebo on all analgesic measures, demonstrating assay sensitivity. Fluradoline, 300 mg, was distinguished from placebo and fluradoline, 150 mg, but not from aspirin, 650 mg. Overall, fluradoline, 300 mg, was equivalent to aspirin, 650 mg. Fluradoline, 300 mg, produced a significant elevation in mood score. Neither aspirin, 650 mg, nor fluradoline caused untoward side effects, but fluradoline, 300 mg, increased blood pressure.
