More specifically, the present invention relates to a pharmaceutical composition suitable for inhibiting pharyngitis by containing loxoprofen and / or its salts. Background Art

[0002] Loxoprofen, known as a propionic acid-based non-steroidal antipyretics, analgesics and anti-inflammatory agents (hereinafter referred to as NSAIDs), shows the same prostaglandin biosynthesis inhibitory effect as other NSAIDs, but has a strong antipyretic / analgesic / anti-inflammatory effect. It is also known that loxoprofen is absorbed by the digestive tract in the form of an unchanged substance with a weak gastric mucosal irritation effect after oral administration, and is a prodrug that forms an active substance in the body. Therefore, it has the characteristic of less gastric mucosal damage compared with other NSAIDs (for example, refer to Non-Patent Document 1). [[ID=—10]]

[0003] Loxoprofen and / or its salts show an anti-inflammatory effect by inhibiting cyclooxygenase and are used for symptomatic treatment of pharyngitis (for example, refer to Patent Document 1).

[0004] On the other hand, the detailed mechanism of action of loxoprofen and / or its salts on pharyngitis has not been fully understood.

[0072] As commercially available peony, peony powder or peony extract (including dried extract, soft extract, etc.) can be used, without particular limitation.

[0073] When using commercially available peony in pharmaceutical compositions, as long as the conversion ratio of the raw drug is taken into account, peony can be used in a way that achieves an appropriate peony content in the tablets.

[0074] In this invention, when using "peony (peony or its extract)", there is no particular limitation on the content. Based on the conversion of raw peony, it is preferred to administer 100-5000 mg per day, more preferably 150-2000 mg, and particularly preferably 200-900 mg, and the number of administrations is 1-3 times per day.

[0075] In this invention, for example, when using dried peony extract, the content of dried peony extract is not particularly limited. Based on the total mass of the pharmaceutical composition, it can be 1 to 50% by mass, preferably 2 to 40% by mass, and more preferably 3 to 20% by mass.

[0076] The pharmaceutical compositions of the present invention can be formulated using conventional methods.

[0077] In this invention, tablets can be manufactured by, for example, producing granulated particles containing loxoprofen or its salt and containing crude drugs selected from (B-1) to (B-7), adding subsequent powder components to the resulting granulated particles in a manner that forms the exterior of the granulated particles, and then compressing them.

[0078] That is, tablets can be manufactured, for example, by the following steps: manufacturing granulated particles (at least one type of granulated particle) containing loxoprofen or its salt and containing crude drugs selected from (B-1) to (B-7); and manufacturing tablets by mixing the aforementioned granulated particles with a desired additive (subsequent powder component) and compressing them. Furthermore, loxoprofen or its salt and the crude drugs selected from (B-1) to (B-7) can be contained in different granulated particles, and the components disposed outside the particles can be arbitrarily formed into granules.

For example, it can be a portion within the tablet that covers one granulated particle, or it can be a portion that covers multiple granulated particles. Alternatively, it can be a portion within the tablet that covers at least one granulated particle and simultaneously forms the outer surface of the tablet. The tablet may have granulated particles within it, and loxoprofen or its salts and crude drugs selected from (B-1) to (B-7) may be contained within the aforementioned granulated particles.

Figure 1 (AA treatment in the middle) can induce pharyngitis.

[0176] <Experiment 2. Measurement of Water Swallowing Reflex> Using the pharyngitis model rats obtained in Experiment 1, such as Figure 2 As shown, the latency time, number of swallowing reflexes, and time interval of swallowing reflexes were measured as an evaluation of pharyngitis. As a method for measuring the water swallowing reflex, under three mixed anesthesia methods (50 mg / kg, intraperitoneal administration), water was administered for 10 seconds via a syringe pump through a cannula inserted into the rat's pharynx using an endoscope. The time until the first reflex occurred (swallowing reflex latency time), the number of swallowing reflexes in 10 seconds from the first reflex, and the time interval of each swallowing reflex were measured.

[0177] The whitening of the endoscopic image was measured as swallowing.

[0178] It should be noted that, as Figure 2 As shown, the preparation groups [1] Sham+Veh group (pharyngeal swab: distilled water, intraperitoneal administration: physiological saline (Veh)), [2] AA10%+Veh group (pharyngeal swab: 10% acetic acid aqueous solution (AA10%), intraperitoneal administration: physiological saline (Veh)), and [3] AA10%+Lox group (pharyngeal swab: 10% acetic acid aqueous solution (AA10%), intraperitoneal administration: loxoprofen 4m / kg) were tested for water swallowing reflex in each group 1 hour after intraperitoneal administration.

[0179] <Experiment 3. Tissue Analysis> Subsequently, rats were perfused and fixed with 4% paraformaldehyde (PFA), and pharyngeal tissue was collected, embedded in paraffin, and then stained with hematoxylin / eosin (HE staining) (refer to...). Figure 3 ).

[0180] like Figure 3 As shown, the degree of edema caused by inflammation is determined by measuring the thickness of the lamina propria.

[0181] One day after acetic acid treatment, in which the water swallowing reflex was most reduced, loxoprofen was administered intraperitoneally at 4 mg / kg. The water swallowing reflex was then measured one hour later (refer to...). Figure 2 , Figure 3 ).

[0182] The control group was given physiological saline (refer to) Figure 2 ).

[0183] <Experimental Results: Experiments 1-3> The results of Experiment 2, such as Figure 4 As shown, in rats with pharyngitis (10% acetic acid aqueous solution treatment group and AA group), the intervals and frequency of swallowing reflexes increased, indicating a decrease in water swallowing reflex function.

[0184] On the other hand, such as Figure 5 As shown, in the loxoprofen administration group of Experiment 2, compared with the control group, the number of swallowing reflexes increased significantly and the time interval between swallowing reflexes was shortened 1 hour after administration. According to... Figure 5 The results showed that loxoprofen tended to restore the reduced water swallowing reflex function caused by pharyngitis.

[0185] like Figure 6 As shown, in HE staining in Experiment 3, infiltration of inflammatory cells was observed in both the loxoprofen administration group and the control group, but in the loxoprofen administration group, the swelling of the submucosa (laminarum propria) was significantly inhibited.

[0186] <Examination of the results of Experiments 1-3> It can be confirmed that acetic acid treatment caused damage to the pharyngeal mucosal epithelium, and simultaneously, inflammation led to swelling of the lamina propria. It can be concluded that this damage to the pharyngeal mucosal epithelium and swelling of the lamina propria result in a decrease in the water swallowing reflex. Figure 4 ).

[0187] In the loxoprofen administration group, recovery of swallowing frequency and swallowing interval, and inhibition of swelling of the lamina propria were observed. Figure 5 , Figure 6 ).

[0188] It should be noted that, 6 days after acetic acid treatment, the latency of the water swallowing reflex, the frequency of swallowing, the regeneration of the mucosal epithelium, and the inhibition of swelling of the lamina propria were confirmed over time. Figure 6 ).

[0189] Based on the results of this experiment, it can be concluded that the recovery of the water swallowing reflex is influenced by [1] the recovery of the mucosal epithelium and [2] the inhibition of swelling of the mucosal lamina propria.

[0190] In addition, based on the results of this experiment, it can be concluded that loxoprofen is particularly helpful in the recovery of the water swallowing reflex by inhibiting the swelling of the mucosal lamina propria [2].

[0191] The above results suggest the possibility that loxoprofen can restore the water swallowing reflex by inhibiting pharyngeal swelling.
