Caffeine enhances and regulates the processes of excitation in the cerebral cortex; in appropriate doses, it enhances positive conditioned reflexes and increases motor activity. The stimulating effect leads to an increase in mental and physical performance, reducing fatigue and drowsiness. Large doses, however, can lead to depletion of nerve cells. Caffeine weakens the effect of hypnotic drugs and narcotic drugs, increases the reflex excitability of the spinal cord, stimulates the respiratory and vasomotor centers. Cardiac activity increases under the influence of caffeine, myocardial contractions become more intense and more frequent.
