- FIG. 3 is a schematic side view of a drug diverging sheet according to another embodiment of the present invention.
- FIG. 4 is a view showing a usage state of the drug divergence sheet shown in FIG. 1.
- FIG. 1 is a plan view of a drug divergence sheet according to an embodiment of the present invention
- FIG. 2 is a side view of the drug divergence sheet.
- the drug divergence sheet of the present embodiment is assumed to be affixed to the forehead in the case of nasal congestion or sore throat due to fever and inhaled from the nasal cavity and Z or oral cavity.
- the drug divergence sheet 1 is composed of a hydrogel layer 2 containing a drug, and is formed in a rectangular shape with a size corresponding to the site to be applied.
- the drug is a 1-menthol liquid with the maximum amount dissolved in glycerin.
- hydrous gel layer 2 As the main material of the gelling agent, carrageenan, locust bean gum, xanthan gum, guar gum, psyllium seed gum, tara gum, dielan gum, sodium alginate, mannan, gelatin, agar, pectin Natural polymer polysaccharides selected from one or more of these are hydrous gels. Illustrative example glycerol 0. 001 20 wt%, 1 over main Ntoru 0. 001- 20 weight 0/0, carrageenan 0. 5-8 weight 0/0, those containing ion-exchanged water 52- 99. about 498 wt% It is possible to include other substances within a range without interfering with other effects.
- carrageenan is mainly used as a gelling agent as the hydrogel layer 2 from the viewpoint of obtaining a large water content while maintaining the adhesiveness and shape retention of the application site.
- the water content before the start of use is 90-99% by weight.
- the drug divergence sheet 1 has a smooth pasting surface 3 on the back side, and an exposed surface 5 having a corrugated surface on the front side.
- the protrusions 4 constituting the waveform of the exposed surface 5 are formed in a strip shape, and a plurality of protrusions 4 are arranged in parallel with each other along the short side direction of the exposed surface 5.
- the height of each protrusion 4 is high enough to increase the surface area of the exposed surface 5. It is preferable.
- the drug diverging sheet 1 configured as described above has a concavo-convex shape at the bottom corresponding to the shape of the protrusion 4 by sequentially mixing the above-described gelling agent and other known additives into purified water.
- the drug divergence sheet 1 is stored in a sealed case (not shown) in advance, and is taken out when necessary, and the pasting surface 3 is pasted on a site to be pasted such as a forehead (Fig. 4).
- the surface area of the exposed surface 5 from which the drug diverges is increased, so that 1 menthol is effectively diverged, and the water content is gradually evaporated, resulting in the latent heat of vaporization at this time. The heat is taken away by this, and the effect of cooling the target region is also achieved.
- the sheet 1 for drug divergence of this embodiment has a large surface area due to the formation of the protrusions 4, and a high evaporation rate can be obtained by increasing the contact area with the outside air. It is effective when a rapid inhalation or rapid cooling of the drug is required.
- the affixing surface 3 can be formed smoothly to ensure a contact area with the site to be cooled and maintain good adhesive performance.
- the shape of the protrusion 4 is not necessarily limited to that of the present embodiment, and may be any configuration that can increase the surface area of the exposed surface 5 such as a curved shape, a ring shape, or a dot shape.
- the ratio of the surface area of the exposed surface 5 to the surface area of the affixed surface 3 (hereinafter simply referred to as “surface area ratio”) is preferably 1.2 or more from the experimental data described later. It is more preferable that There is no particular upper limit for the surface area ratio, but it is 2 or less from a practical viewpoint.
- the hydrous gel layer 2 may be polyacrylic acid, polymethacrylic acid, polyacrylic acid salt, polymethacrylic acid salt, or the like as the main material of the gelling agent. It is possible to use a polyacrylic acid containing a plurality of selected polyacrylic acids containing about 19.5% by weight with respect to the entire hydrogel layer 2. If it is difficult to maintain the shape of the hydrated gel layer 2 itself by selecting such a material, as shown in FIG. 3, the sheet 11 for releasing the drug is permeable to the exposed surface 5 side of the hydrated gel layer 2.
- the sheet-like support 6 having the above may be laminated.
- FIG. 3 the same components as those in FIGS. 1 and 2 are denoted by the same reference numerals.
- the support 6 has a protrusion 41 formed on the surface by embossing, and the hydrogel layer 2 is laminated on the support 6 having such a protrusion 41 so that the hydrogel layer 2
- the protrusion 4 is also formed. That is, the surface area of the exposed surface 5 of the hydrated gel layer 2 increases as in the configuration shown in FIGS. As a result, the divergence of the drug in the hydrogel layer 2 and the evaporation of moisture are promoted through the support 6, which is high! ⁇ Drug divergence effect and high! ⁇ Cooling effect can be obtained.
- a release film (not shown) that can be removed at the time of use is preferably laminated on the sticking surface 3 of the hydrogel layer 2.
- the support 6 is woven in addition to the non-woven fabric as long as it has moisture permeability and air permeability so that the divergence of the drug on the exposed surface 5 of the hydrogel layer 2 and the evaporation of moisture are not inhibited. It is also possible to use a cloth, a knitted fabric, etc. Furthermore, it is also possible to use a porous resin film having strength such as polypropylene and polyethylene terephthalate.
- the surface area ratio of the hydrogel layer 2 and the height of the protrusions 4 are preferably set in the above-described numerical ranges.
- the surface area ratio of the hydrated gel layer 2 can be determined for convenience by comparing the surface area of the support 6 surface to the surface area of the affixing surface 3 of the hydrated gel layer 2.
- the height can be determined for convenience from the height of the protrusion 41 of the support 6.
- the above-mentioned sheet for releasing drug according to the present invention is used for cooling in the event of heat generation.
- it can be used as a Si Si poultice.
- Example 1 projection top spacing: 4 mm, height: 2 mm, surface area ratio: 1.57
- Example 2 projection top spacing: 2 mm, height: lmm, surface area ratio: 1. 56
- Example 3 projection height: lmm, surface area ratio: 1.2
- Example 4 projection height: 0.5 mm, surface area ratio: 1.1
- Comparative Example 1 surface area ratio: 1.0
- the adhesive surface of the drug divergence sheet was affixed on a hot plate, energized at 0.7 W, and the weight loss value over time of the drug divergence sheet was measured. Then, from the weight loss value, the divergence amount of 3% of 1 menthol was calculated (additionally described after each time, and the average value per hour over 4 hours is shown as an average). The results are shown in Table 1.
- Example 1 Furthermore, a sensory evaluation was performed 3 hours after applying it to the forehead of Example 1 and Comparative Example 1 for 3 patients with symptoms of pain in the nose and sore throat. In contrast to the fact that the nasal passage was relieved, Example 1 replied that the nasal passage was settled and the sore throat was relieved.
