The study aimed to evaluate and compare two methods of assessing respiratory safety in rats to determine the best approach for identifying drug-induced respiratory issues in preclinical research.
Different plethysmography techniques (head out and whole body) were utilized to measure parameters like respiratory rate and tidal volume, specifically testing the effects of drugs like theophylline, chlordiazepoxide, and propranolol.
Results indicated that head out plethysmography might provide more reliable data on ventilatory function, although additional invasive methods may be necessary for comprehensive airway function assessment.
