Abstract

PURPOSE:To obtain the titled nontoxic drug useful for keeping the mydriasis or anti-inflammation after operation, by incorporating 2-(2-fluoro-4-biphenylyl) propionic acid or a salt thereof with beta- or gamma-cyclodextrin in a specific proportion. CONSTITUTION:An anti-inflammatory ophthalmic solution prepared by adding and dissolving 2-(2-fluoro-4-biphenylyl)propionic acid (hereinafter abbreviated to FP) or a salt thereof and beta-cyclodextrin (hereinafter abbreviated to beta-CD) or gamma- cyclodextrin (hereinafter abbreviated to gamma-CD) at 1:(0.5-2.5) ratio in an aqueous medium, and preferably incorporating a viscosity increasing agent, e.g. polyvinyl alcohol, therewith, and adjusting the pH to 5.0-8.0 with a buffering agent. A clathrate compound of beta-CD or gamma-CD may be similarly used to prepare the solution. The presence of the beta-CD or gamma-CD reduces greatly the irritation to human eyes and increases the concentration of FP. Thus, the FP can be applied in a high concentration, and the solution is stable for a long time.

When trauma is applied locally to the eye by surgery on the anterior segment of the human eye, such as surgery for strabismus, cataract, glaucoma, etc., prostaglandins (hereinafter referred to as PGs) are biosynthesized and released from the eye tissue.

Furthermore, it is known that a large amount of PGs is released into the anterior aqueous humor not only due to such mechanical stimulation but also during certain types of uveitis such as Behcet's disease and ciliary body attack of glaucoma.

By the way, it has been clearly shown that the PGs released in this way cause miosis, postoperative inflammation, or increase intraocular pressure. Therefore, when performing surgery for soft cataracts, etc., the pupils are made well-dispersed with atropine or the like before surgery, but miosis often occurs during the surgery, making the surgery difficult.

Therefore, in order to inhibit the biosynthesis of PGs, which is the cause of these symptoms, to make the procedure easier, and to reduce postoperative complications and inflammation, nonsteroidal anti-inflammatory drugs that have a PGs biosynthesis inhibiting effect are used. Oral administration of aspirin or indomethacin has been attempted.

However, when these drugs are taken orally, there is little drug transfer to the ocular area, so they are not effective unless taken in large doses. However, multiple doses of aspirin and indomethacin are associated with side effects such as gastrointestinal disorders, and cannot be used clinically.

Therefore, the present inventors aimed to formulate FP, which has a strong PGs inhibitory effect, more accurately as a safer ophthalmic solution. As a result of extensive research aimed at creating a formulation that is stable for long periods of time and does not cause local irritation, it is possible to apply high concentrations by solubilizing FP or its ophthalmologically acceptable salts to β-CD. Alternatively, the present invention was completed based on the discovery that the object of diagonal elevation can be achieved by using it in combination with γ-CD.

In the present invention, the irritation of FP to the human eye usually becomes stronger when the FP concentration exceeds 0.2%, and there was a concern that side effects such as corneal ulcers and conjunctival edema would occur rather than drug efficacy, but β-
In the coexistence of CD-straddling r-CD, the irritation of FP to human eyes is greatly attenuated and no side effects occur;
In addition, the anti-inflammatory effect of FP depends on the intraocular FP concentration, which is greatly increased in the coexistence of β-CD or γ-CD, and is effective not only at high concentrations but also at low concentrations; In addition, FPO can be solubilized at high concentrations in the coexistence of β-CD and γ-CD, and in combination with the above-mentioned stimulation region, FP
It is possible to apply high concentration of O, and furthermore, it is possible to apply KFP to β-CD.

.. 6.7.9 and 12-14 (compound preparations of 11'P and β-CD) and 50 μl of the ophthalmic solutions of Experiment No. 1 (yp single preparation) were applied to one eye of the rabbit for 6 hours before anterior chamber puncture.12 A total of 4 eye drops were applied for a time of 11 hours and a time of 0.5 hours. In the remaining eye, only the base of the corresponding ophthalmic solution was instilled in the same way.
This was used as a control. The rabbit was immobilized and the anterior aqueous humor was collected using a syringe needle under anesthesia (primary aqueous humor), and the aqueous humor was collected again one and a half hours after the aqueous humor collection (secondary aqueous humor). The protein concentration in each sampled aqueous humor was measured according to the method of Lowry et al. The results are shown in Figure 2.

In the case of the combination preparation of FP and β-CD of the present invention, the irritation level is much lower than that of the B'P single preparation, and the amount of FP transferred into the eye is particularly low due to the small amount of extra-flow due to sintering. p
It showed a significantly high value in the H region.
