In rat ileal smooth muscle, 1-10 mM caffeine inhibited spontaneous contractile behaviour, abolished spike activity and reduced KCl-induced contracture tension. 3. Enhanced spike activity associated with the KCl-induced phasic contraction was abolished by caffeine, the degree of caffeine-induced relaxation being proportional to the concentration employed...
