SPECIFIC EFFICIENCY OF MICROEMULSION MATRIX TRANSDERMAL DELIVERY SYSTEM OF INSULIN (EXPERIMENTAL MODEL OF DIABETES MELLITUS TYPE I)
Aim. To study the specific activity of the microemulsion form of the matrix insulin transdermal delivery system in vivo on the experimental streptozotocin model of type I diabetes. Materials and methods. Male rats (n = 25) were randomized to the experimental and control groups. TDS insulin with a microemulsion composition was applicated to the animals of the experimental group (n = 15) for 4 days with daily replacement of TDS and control of the glycemia level. The glycemia level of the control group rats (n = 10) was determined throughout the experiment. The blood glucose concentration was measured using glucometer One Touch Select (USA). Results. The average blood glucose level in experimental group was 28.4 ± 2.3 mmol/l before application of TDS insulin. The average glycemic index was 21.2 ± 3.1 mmol/l (p < 0.001) during of TDS application. The blood glucose decrease was 26 ± 8% relative to baseline values. The glycemia was 28.4 ± 1.4 mmol/l in the control group rats throughout the experiment. Conclusion. A significant decrease of blood glucose level with TDS insulin application in rats with experimental type 1 diabetes demonstrates the existence of the specific activity of the microemulsion matrix transdermal delivery system of insulin.
