Problems solved by technology

[0003] However, iodine is not only very unstable relative to light, heat, and air, but also easily adsorbed on the inner wall of the container.
Therefore, iodine-containing preparations have a problem that the iodine content tends to decrease during storage.

Embodiment approach 1

[0024] One embodiment of the present invention will be described in detail below. In addition, in this specification, unless otherwise specified, "A-B" which shows a numerical range means "A or more and B or less." The term "about" used in this specification means within the range of ±10% of the stated amount.

[0025] In the present invention, the ophthalmic product refers to an ophthalmic product obtained by storing an ophthalmic composition in a container, and more specifically refers to a product for ophthalmic medicine. The ophthalmic product according to this embodiment is characterized by the material of the container for storing the ophthalmic composition. Conventionally, containers for storing ophthalmic compositions are made of glass.

[0026] The inventors of the present application focused on the fact that plastic containers are less likely to break and can manufacture small and free-form products with good precision, and intensively studied plastic materials sui...

Abstract

The purpose of the present invention is to suppress the reduction of the percentage of the iodine content in an ophthalmic composition during storage. This ophthalmic product (A) according to the present invention is made by accommodating, in a container (10), an iodine raw liquid (I) containing iodine and poly vinyl alcohol as active ingredients, and the container (10) is made of at least one material selected from the group consisting of a fluorine-based resin, a polyethylene-based resin, and a polyethylene terephthalate resin.

Description

technical field [0001] The present invention relates to ophthalmic preparations and their use. Background technique [0002] Conventionally, iodine-containing preparations containing iodine and polyvinyl alcohol have been used as ophthalmic agents for the purpose of sterilization, cleaning, and the like. For example, Patent Document 1 discloses eye drops containing iodine and polyvinyl alcohol. [0003] However, iodine is not only very unstable with respect to light, heat, and air, but also easily adsorbed on the inner wall of the container. Therefore, iodine-containing preparations have a problem that the iodine content is likely to decrease during storage. Therefore, iodine-containing preparations are usually kept cold and circulated in glass brown bottles that do not easily absorb iodine and can be shielded from light.
