Description

The present invention suppresses the adsorption of chlorobutanol to the silicone hydrogel contact lens even when it is applied to a silicone hydrogel contact lens while containing chlorobutanol. The present invention relates to an ophthalmic composition for a silicone hydrogel contact lens that can be used safely by facilitating elution by elution treatment with a saline solution or the like. The present invention also relates to a method for suppressing adsorption of chlorobutanol to a silicone hydrogel contact lens. Furthermore, the present invention relates to a method for suppressing bacterial adhesion to a silicone hydrogel contact lens.

In recent years, the number of wearers of contact lenses (CL) has increased, and in particular, the number of wearers of soft contact lenses (SCL) has increased. In general, it has been pointed out that when a soft contact lens is worn, the amount of oxygen supplied from the atmosphere decreases, which may result in suppression of corneal epithelial cell division and thickening of the cornea. Therefore, development of soft contact lenses having higher oxygen permeability has been advanced.

Under such circumstances, silicone hydrogel contact lenses have been developed in recent years as soft contact lenses having high oxygen permeability. Silicone hydrogel contact lenses achieve oxygen permeability several times that of conventional hydrogel contact lenses by blending silicone with hydrogel. Therefore, it is highly expected that the oxygen supply shortage, which is a weak point of the soft contact lens, can be improved and the adverse effects on the cornea due to the oxygen shortage can be greatly suppressed.

In general, it is important that an ophthalmic composition used for a contact lens is designed in consideration of safety and other effects depending on the type of contact lens. In particular, soft contact lenses vary depending on the material, such as the presence or absence of ionicity and the level of moisture content.
It is important to design an ophthalmic composition for a soft contact lens according to the characteristics of the soft contact lens to be applied.

On the other hand, chlorobutanol has been used in ophthalmic compositions as a preservative. It is also known that chlorobutanol has a problem that it is very easily adsorbed to conventional soft contact lenses (Patent Document 1).

However, until now, the effect of chlorobutanol on silicone hydrogel contact lenses has not been elucidated at all. In addition, when chlorobutanol and other specific components are used in combination, there is currently no appreciable effect on the silicone hydrogel contact lens.

International Publication No. 05/025539 Pamphlet

Chlorobutanol is a component that is desired to be used for preserving ophthalmic compositions, but the present inventor has conducted various studies on the influence of chlorobutanol on various soft contact lenses. The present inventors have obtained a new finding that butanol is very easily adsorbed to a silicone hydrogel contact lens (hereinafter sometimes referred to as SHCL) as compared with a conventional hydrogel lens. The amount of chlorobutanol adsorbed on SHCL is an amount that cannot be compared with that of conventional hydrogel contact lenses. Further, as a result of further investigation, the present inventor has found that a large amount of chlorobutanol still remains even when the SHCL after adsorption of chlorobutanol is subjected to an elution treatment with physiological saline. This means that a large amount of adsorbed chlorobutanol remains in the SHCL without being washed away by tears or the like. If the preservative component remains and accumulates in the lens in this way, there are concerns about the adverse effects of the component remaining on the lens.
May cause discoloration, decrease in light transmittance, deformation, and the like.

The ophthalmic composition for SHCL of the present invention can suppress the adsorption of chlorobutanol to SHCL, and even if chlorobutanol is once adsorbed to SHCL, the chlorobutanol can be easily washed away with tears or SHCL washing solution. It is possible to reduce the residual amount of chlorobutanol in SHCL.

Furthermore, although SHCL has a great merit that it can supply a sufficient amount of oxygen to the cornea, it also has the disadvantage that conjunctiva bacteria are likely to adhere (MDP Willcox et al., B
acterial interactions with contact lenses; effects of lens material, lens wear a
nd microbial physiology, Biomaterials 22 (2001), 3235-3247). Many conjunctival resident bacteria are non-pathogenic, but if excessive adhesion or proliferation occurs, a biofilm is formed on the surface of SHCL by extracellular substances secreted from the attached / proliferated bacteria, causing pathogenicity. There is a danger of becoming a hotbed of microorganisms. Furthermore, since SHCL has a high oxygen permeability, it may be worn continuously for up to 1 month, so it can be said that it tends to promote bacterial adhesion during wearing, which is one of the risk factors for bacterial infections. It is also pointed out. On the other hand, according to the ophthalmic composition for SHCL of the present invention, since bacterial adhesion to SHCL can be suppressed, the growth of pathogenic microorganisms can be suppressed, and bacterial infection can be achieved even after prolonged SHCL wearing. The risk of this can be reduced and SHCL can be used safely.

Then, by subtracting the chlorobutanol elution amount from the chlorobutanol adsorption amount on the soft contact lens, the amount of chlorobutanol remaining on the soft contact lens after treatment with physiological saline (the residual amount of chlorobutanol) was calculated. .

As a result, the chlorobutanol adsorption amount of each soft contact lens is shown in FIG. 1, and the chlorobutanol residual amount in each soft contact lens after elution treatment with physiological saline is shown in FIG. As is clear from this result, compared to conventional hydrogel lenses (lenses A and B), SHCL (lenses C to E) remarkably easily adsorbs chlorobutanol (FIG. 1), and in physiological saline. Even after elution, chlorobutanol is not sufficiently eluted and a large amount of SH
It was confirmed that there was a unique problem of remaining in CL (FIG. 2). Above all, this problem was remarkable in ionic SHCL (lens C).

CL), and using the test solutions shown in Table 3 (Examples 1-4 and Comparative Example 1), the amount of chlorobutanol adsorbed on SHCL and physiological saline by the same test as in Reference Test Example 1 above The residual amount of chlorobutanol in the SHCL after elution treatment was determined.

As a result, the results of measuring the amount of chlorobutanol adsorbed on SHCL when each test solution is used are shown in FIG. 3, and when each test solution is used, the results after elution treatment with physiological saline are shown.
The results of measuring the residual amount of chlorobutanol in SHCL are shown in FIG. As is clear from this result, hydroxypropylmethylcellulose, alginic acid, chlorobutanol,
Test solution containing sodium chondroitin sulfate or sodium hyaluronate (Example 1-
In 4), the amount of chlorobutanol adsorbed on SHCL was suppressed as compared to the test solution containing chlorobutanol alone (Comparative Example 1) (FIG. 3), and chlorobutanol remained after elution with physiological saline. It was found that the amount was significantly reduced (FIG. 4). In particular, when chondroitin sulfate sodium or sodium hyaluronate is used (Example 3-4), the residual amount after elution treatment with physiological saline can be significantly reduced, and chlorobutanol on SHCL can be reduced. It was confirmed that the residue after adsorption and elution treatment can be effectively suppressed, and an extremely safe ophthalmic composition for SHCL can be obtained while containing chlorobutanol.

Test Example 2: Test for evaluating bacterial adhesion to SHCL (1)
The adhesion of Staphylococcus aureus (ATCC No. 6538) to various soft contact lenses was evaluated using the test solutions shown in the following table (Example 5-6 and Comparative Example 2-3). The lens is SHCL, Lens F (nonionic SHCL, main constituent monomer: N, N-dimethylacrylamide, pyrrolidone compound, silicon-containing methacrylate compound, silicon-containing acrylate compound (USAN: Asmofilcon A), water content 40% , BC8.60, DIA14.0)
The lens B of Reference Test Example 1 was used as a non-silicone hydrogel contact lens (non-SHCL).

First, each lens was immersed in 5 mL of sterile physiological saline for 4 hours or more (lens pretreatment). Next, 1 mL of each test solution (Examples 5-6 and Comparative Example 2-3) was placed in a 24-well multiplate, and pretreated SHCLs were placed one by one. Further, non-silicone hydrogel contact lenses were similarly treated with the test solution according to Comparative Example 2. After overnight treatment, lightly absorb the moisture on the surface of each lens with a non-woven fabric, and then 10 ^7-8 CFU / mL of S.
Place in a 6-well multiplate containing 5 mL of aureus bacterial solution (suspended in physiological saline), 30
Stored at room temperature for minutes. After 30 minutes, each lens was transferred to a 6-well plate containing 5 mL of physiological saline with tweezers and shaken for 1 minute. Next, each lens is transferred to a Spitz tube containing 5 mL of new physiological saline, subjected to ultrasonic waves (38 kHz) for 3 minutes, and then stirred for 1 minute in a test tube mixer to remove bacteria attached to each lens. The adherent bacteria solution was used.

The obtained adherent bacterial solution was diluted to an appropriate concentration and seeded on a soy bean / casein / digest / agar medium (SCDLP agar medium). After culturing overnight at 33 ° C., the number of colonies observed was counted, and the number of bacteria attached to each lens (viable cell count) was determined by correcting with the dilution factor.

The results are shown in FIG. 5 below. As shown in FIG. 5, it is recognized that SHCL is remarkably easier to attach S. aureus than non-silicone hydrogel lenses (Comparative Example 2), and the number of adherent bacteria is slightly reduced by the addition of chlorobutanol. Was observed (Comparative Example 3). On the other hand, unexpectedly, it was recognized that the number of bacteria attached to SHCL can be significantly reduced by applying hydroxypropylmethylcellulose in combination with this chlorobutanol (Example 5). Furthermore, it became clear that the number of adherent bacteria can be reduced more remarkably by combining allantoin with chlorobutanol and hydroxypropylmethylcellulose (Example 6).

Test Example 3: Evaluation test for bacterial adhesion to SHCL (2)
For the test solutions shown in the following table (Examples 7-9 and Comparative Example 4), the type of SHCL used was substantially the same as Test Example 2 except that the lens D of Reference Test Example 1 was changed. SH
The adhesion of Staphylococcus aureus (ATCC No. 6538) to CL was evaluated.

The results are shown in FIG. 6 below. As shown in FIG. 6, even when the type of SHCL was changed, the same bacterial adhesion inhibitory effect as in Test Example 2 was confirmed by the combination of chlorobutanol and hydroxypropylmethylcellulose (Example 7). In addition, it was also clarified that even when pyridoxine hydrochloride or tetrahydrozoline hydrochloride is further combined with chlorobutanol and hydroxypropylmethylcellulose, a more remarkable effect of suppressing bacterial adhesion is exhibited (Examples 8 and 9). .

Test Example 4: Evaluation test for bacterial adhesion to SHCL (3)
For the test solutions (Examples 10-11 and Comparative Example 5) shown in the following table, Staphylococcus to SHCL using the lens F of Test Example 2 as SHCL in substantially the same manner as Test Example 2 above.
The adhesion of aureus (ATCC No. 6538) was evaluated.

The results are shown in FIG. 7 below. As shown in FIG. 7, even when sodium chondroitin sulfate was used in place of hydroxypropylmethylcellulose, it was confirmed that the same bacterial adhesion inhibitory effect as in the previous test examples was exhibited (Examples). 10-11).
