Thereby, the medicine 104b can be penetrated into the skin from a wide range.
- the adhesive layer 104 that is, the area where the drug 104b is in contact with the skin can be increased by integrating the plurality of electrodes 102 on one sheet. This can advantageously increase the amount of penetration.
- a drug such as bisoprolol having an effect on the circulatory system is used as the drug 104b.
- Cardiovascular drugs unlike poultices, do not differ greatly in their medicinal effects depending on the position where they are applied. In other words, you can choose almost no position. Therefore, it is suitable for a variety of attachment positions such as an electrocardiogram measurement electrode.
