A Bisoprolol patch, wherein the skin penetration rate of Bisoprolol after 24 hours is 15 to 60% of the maximum skin penetration rate thereof, shows a little difference between the maximum level of the concentration in blood and the minimum level thereof in repeated administration and, therefore, scarcely exhibits side effects. Moreover, it achieves the quick development of the drug effect owing to the stabilization of the concentration in blood within a short time.
