title: [Effect of pyracetam on fatigue of inspiratory muscles in cats].
abstract: The aim of the work was to study the influence of pyracetam on respiratory muscles fatigue and ventilatory disorders caused by inspiratory resistive load in cats. The experiments have show that after the use of pyracetam in conditions of fatigue total bioelectric activities of inspiratory muscles and of the phrenic nerve and transdiaphragmal pressure restore; duty cycle, respiratory rate and tidal volume per minute decrease. The conclusion is drawn that pyracetam in the dose 300 mg/kg, in intravenous administration, compensates inspiratory muscle fatigue at the expense of its central mechanism of action.
