[Industrial Field of Application] The present invention relates to a container for a rectally administered drug, and more particularly to a container for a rectally administered drug that can be effectively inserted into the rectum through the anus. [Prior Art] Rectal preparations for administering drugs from the anus to the rectum include suppositories and injectable ointments. In recent years, the usefulness of such rectally administered preparations has been reconsidered compared to orally administered preparations. This is based on the fact that rectally administered preparations do not affect the gastric mucosa, are not affected by the first pass effect in the liver, and are easy to administer to children and the elderly. Among the rectal preparations, suppositories are most commonly used. On the other hand, injectable ointments have the advantage of being easy to adjust and have a wide range of base selectivity, but are only rarely used in pharmaceutical preparations, and are only used in some hemorrhoid medicines. . Therefore, conventional injectable ointments generally contain drugs such as Vaseline, Carbopol gel,
It is used by mixing it with a base such as a cream and placing it in a polyethylene tube with a protrusion for insertion into the anus, or in a syringe. [Problem that the invention aims to solve] The rectum is the end of the large intestine that connects to the anus. When administering an injectable ointment or the like into the rectum via the anus, the person generally holds back, extends his/her hand forward or backward, and inserts the protruding part of the injectable ointment container into the anus. When taking this position, the upper body leans forward, and the path from the anus to the rectum leans forward and deviates from the vertical line. In such a case, in a conventional container for a preparation to be administered rectally, the protruding direction of the rectal insertion portion from the container body coincides with the vertical line, in other words, the inclination angle with respect to the vertical line is O. Therefore, when inserting an injectable ointment container having such an insertion protrusion into the anus while leaning forward, the insertion protrusion is inserted perpendicularly above the anus; Since the path from the anus to the rectum is inclined forward from the vertical line, problems such as difficulty in inserting the protrusion are inevitable. Therefore, although injectable ointments have the advantages of ease of adjustment and a wide range of base selectivity as mentioned above, they are not generally accepted because of the difficulty in inserting them. The reality was that it had an influence. In particular, people who use injectable ointments are people who have a disease, especially those who suffer from hemorrhoids, so it is important that the protrusion is inserted smoothly and effortlessly. There has been a strong desire for improvements in this industry and patients. [Means for Solving the Problems] Under these circumstances, the inventor of the present invention overcame the shortcomings of the conventional rectal administration preparation containers and, as a result of intensive studies, developed a new method that would be better than the container itself. It has been found that if a container is formed in which the protruding rectal insertion part is inclined at 5 to 35 degrees with respect to the vertical line and used as an injectable ointment container, the rectal insertion part can be easily and smoothly inserted into the anus. , devised this idea. That is, in the present invention, a drug discharge hole that slopes downward outward is formed in the side wall of the rectal insertion part, which is formed protrudingly at an angle of 5 to 35 degrees with respect to the vertical line at the upper part of the container body, and the drug discharge hole is This is a rectal administration preparation container characterized by having a rounded outer edge of the opening. [Examples] The present invention will be further explained below with reference to drawings showing examples. Reference numeral 1 denotes a container body, which may have any shape such as a sphere, a square, or a cone. Reference numeral 2 denotes a rectal insertion portion, which is formed protruding from the upper part of the container body 1 at an angle of 5 to 35 degrees, preferably 10 to 20 degrees, relative to the vertical line 1. Here, the inclination angle α of the rectal insertion part 2 with respect to the vertical line l is:
This refers to the intersection angle between a virtual straight line m connecting the center point P of the distal end of the rectal insertion portion 2 and the center point Q of the base, and a vertical line l passing through the center point Q of the base. Incidentally, if the inclination angle α is less than 5 degrees, the difficulty of insertion into the anus will hardly be improved;
If this is exceeded, the container itself will have to be tilted when inserted into the anus, and the purpose of the present invention will not be achieved. The rectal insertion portion 2 may have any shape, but from the viewpoint of ease of insertion, a cylindrical shape, particularly a cylindrical shape with a rounded tip, is preferable. Furthermore, the rectal insertion section 2 can be not only linear but also curved. The inclination angle α in this case is also the intersection angle of the above-mentioned virtual straight line m and the vertical line L.
From the viewpoint of ease of insertion into the anus, it is preferable that the intersecting angle β with the vertical line 1 passing through the central point Q of the base end be within ±10 degrees with respect to the inclination angle. Reference numeral 3 denotes a drug discharge hole, which is formed in the side wall of the rectal insertion portion 2 other than the tip thereof. Although the specific number of drug discharge holes 3 is not limited,
From the viewpoint of drug excretion into the rectum, the number is preferably about 2 to 8. Further, a tip discharge hole 4 may be used together with the side wall discharge hole 3, but in this case, it is preferable that the opening area of the tip discharge hole 4 is smaller than that of the side wall discharge hole 3. Furthermore, since the drug discharge hole 3 is an oblique hole that slopes downward outward, it has the excellent effect that the discharged drug is more easily directed toward the affected area. Furthermore, since the opening outer edge 31 of the drug discharge hole 3 is rounded, it provides good results in reducing discomfort such as catching when inserting and removing the rectal insertion portion 2. . Incidentally, the drug evacuation hole of conventional rectal administration drug containers was formed only at the tip of the rectal insertion part.
When used by a person with hemorrhoid disease, the drug excreted upwards from the affected area of the lower rectum and end. Therefore, the drug discharged into the rectum hardly ever comes into contact with the affected area and is essentially wasted, which naturally poses a problem in terms of therapeutic efficacy. By forming the side wall discharge hole 3 as described above, the discharged drug can be reliably administered to the hemorrhoid diseased area, which naturally improves the therapeutic effect, which is more advantageous. In addition, since the rectal administration drug container of the present invention, which is composed of the container body 1 and the rectal insertion part 2 as described above, pushes out the drug content by compressing the container body 1 with fingers and fingers, the material is It is preferable to use a material that is easily deformed by pressure, such as polyethylene, and in particular, use of a material laminated with aluminum will give better results in terms of stability of the drug content. Rectally administered preparations can be obtained by filling such a container with an ointment or cream-like drug, but in the present invention, the entire amount is injected at once, or the drug is injected several times to more than ten times. It can be applied to anything that can be done. Next, the present invention will be further explained by giving a test example of the rectal administration preparation container according to the present invention. Test example: The rectal insertion part of a conventional polyethylene injectable ointment container with a capacity of 2 ml, which has a rectal insertion part of 0.6 cm in diameter and 2.6 cm in length, is slowly heated and applied with weight to align the rectal insertion part with the vertical line. On the other hand, they were each tilted at a certain angle. After cooling, warmed and molten white petrolatum was poured into a container having rectal insertion portions having respective angles through the bottom opening, and then the openings were heat-sealed to obtain an anal injection ointment. The resulting injectable ointment was inserted into the anus of 20 normal male subjects to investigate the ease of insertion. The results are shown in Table-1.

[Function and Effects] Since the rectal administration preparation container of the present invention is constructed as described above, if it is used, it will be possible to align the line from the anus to the rectum of a person in a supine state and the protruding direction of the rectal insertion part. Since they match, the rectal insertion part can be inserted into the anus very smoothly and without difficulty. Therefore, according to the present invention, even a person who is using a rectal preparation for the first time can easily and reliably inject and administer a drug, so it has great practical value.
