preparation example 1

[0266]

[0267] #1 MPC polymer is the same polymer used in Table 1.

[0268] The prescription of the ophthalmic composition of the above-mentioned formulation example 1 was prepared according to a conventional method, and 15 mL was filled into a 15-mL PET container, and an eye drop and an eye drop for SHCL were prepared respectively.

[0271]

[0272] #1 MPC polymer is the same polymer used in Table 1.

[0273] The ophthalmic composition prescription of the above-mentioned formulation example 2 was prepared according to a conventional method, and 10 mL was filled into a 10 mL capacity PET container to prepare eye drops, contact lens filling solutions, eye drops for SHCL, and contact lens filling solutions for SHCL, respectively. In addition, instead of the above-mentioned container, 500 mL was filled into a 500 mL-capacity PET container, and an eye wash and an eye wash for SHCL were produced, respectively.

Abstract

Disclosed are: an ophthalmic composition according to a non-conventional novel preparation, which has histamine release inhibitory action; and an ophthalmic composition for a silicone hydrogel contact lens, which is capable of suppressing adsorption of terpenoid to a silicone hydrogel contact lens. Specifically, the ophthalmic composition is prepared using (A) 0.001-2 w/v% of a polymer that has a phosphorylcholine analogous group in a side chain in combination with (B-1) 0.001-0.02 w/v% of menthol. Meanwhile, the ophthalmic composition for a silicone hydrogel contact lens is prepared using (A) a polymer that has a phosphorylcholine analogous group in a side chain in combination with (B-2) terpenoid.

Description

technical field [0001] The present invention relates to ophthalmic compositions exhibiting an inhibitory effect on histamine release. Moreover, this invention relates to the ophthalmic composition for silicone hydrogel contact lenses which can suppress the adsorption|suction of a terpenoid compound to a silicone hydrogel contact lens. Background technique [0002] In recent years, the increase of allergic patients and the aggravation of allergic symptoms have become a problem. It is known that most of the symptoms of allergic patients are type I allergic symptoms, that is, allergic symptoms caused by the release of chemical transmitters such as histamine from mast cells and basophils through contact with allergens. In order to prevent and improve this type I allergic symptom, it is effective to inhibit the release of histamine itself, and the development of an ophthalmic composition exhibiting a histamine release inhibitory effect has been desired. In particular, if an oph...
