Definitions
- the present invention relates to an insulin administration device for administering insulin orally to a skin or mucous membrane using the force of an electric field.
- Diabetic patients can be broadly divided into type 2 diabetic patients who can be treated with oral diabetes, such as sulfonylurea, and type 1 diabetic patients who have no secretion of insulin.
- Patients with type 1 diabetes need to administer insulin because insulin is not secreted.
- a treatment method similar to type 1 is used to administer insulin.
- Insulin however, has a high glycemic control effect, but its absorption and stability are poor, making it impossible to administer it orally.

- Comparative Example 2 applies only the electoral portation. Insulin Lisp was administered respectively.
- Example 1 showed a maximum blood concentration of 1200 ⁇ units / mL in the insulin lip mouth, but in Comparative Examples 1 and 2, almost all of the insulin rins mouth was detected. Was not done.
- Example 1 and Comparative Examples 1 and 2 are shown in the graph of FIG. 8 as the ratio of the blood glucose level after administration to the initial (before administration) blood glucose level.
- Example 1 the insulin lip mouth absorption was so high as to drop to the initial 9% at 120 minutes after the administration, and then to appear rats dying due to hypoglycemia.
- Comparative Examples 1 and 2 the drop was only about 80% after 120 minutes. That is, it was shown that only the combination of the election port and the tip foreresis can obtain the high absorption of the insulin port.
- Example 1 The blood insulin levels of Example 1 and Comparative Example 3 are shown in the graph of FIG. Fig. 9 shows a comparison of the absorption of other insulin when using electoral poration and iontophoresis.
- Example 1 Insulin respiratory port was administered using electroporation and iontophoresis
- Comparative Example 3 human insulin was administered using electoral poration and iontophoresis.
- the type of insulin is different, but the dosage is the same at approximately 500 units / mL.
- Example 1 showed a maximum blood insulin concentration of 1200 units Zml
- Comparative Example 3 showed a blood insulin concentration of about 100 units / mL. I can only get it.
- FIG. 10 is a graph showing the change in blood glucose level of Example 1 and Comparative Example 3 as a ratio of the blood glucose level after administration to the initial (before administration) blood glucose level. Show. As shown in Fig. 10, the drug efficacy also decreased to an initial value of 9% at 120 minutes after administration in the insulin lip mouth, whereas it decreased only about 40% in human insulin. In other words, a comparison between Example 1 and Comparative Example 3 shows that sufficient absorption cannot be obtained without the use of the insulin lip mouth, even if election port por- tion and iontophoresis are used.
- Fig. 11 shows that the concentration of the administered solution for both insulin lip mouth and human insulin was 100 units Zml, and the blood concentration when insulin was administered using electoporation and iontophoresis. It is shown.
- Example 2 the maximum blood concentration was about 700 microunits / mL, even when the administration concentration was 1/5 of that in Example 1, indicating an extremely high absorption compared to Comparative Example 4. I got it.
- FIG. 12 shows that the other insulins (arginine mono-insulin, bush insulin, and peroxy-insulin) were used in the same manner as in Example 2 and Comparative Example 4 by using electoporation and iontophoresis.
- FIG. 4 shows the time course of blood glucose when administered in mL. As is evident from Fig. 11, the glucose concentration decreased to 20% of the initial value only when the insulin lip mouth was used, and decreased to 65% when any other insulin was used. It was not too much.
- Examples of formulations used in the above-mentioned electroporation-iontophoresis preparations are shown in Examples 3 to 7 below.
- the compositions prepared according to these formulations can be added to the above-mentioned elect-portion-iontophoresis preparations and used as administration preparations.
- Insulin lip mouth 500 units solution
- Insulin lip mouth 0.2 mL
- Insulin lip mouth 500 unit solution
- Insulin lip mouth 0.2 mL
- Insulin lip mouth 500 unit solution
- Insulin lip mouth 0.2mL
- Insulin lip mouth 500 units solution
- Insulin lip mouth 0.2 mL
- Insulin lip mouth 500 unit solution
- Insulin lip mouth 0.2mL
- an insulin administration device which enables effective transdermal or transmucosal administration of insulin.
