- the present invention relates to a solid external medicine for ophthalmology in which a part of the drug is applied to the skin surface and the pharmacologically active component is transferred to the local ocular tissue such as conjunctiva and cornea through the skin.
- an eye drop is the most common, and in addition, an eye ointment is used.
- the drug is directly brought into contact with the cornea or conjunctiva of the eye to transfer the pharmacologically active ingredient to those sites.
- eye drops are easy to administer and have excellent immediate effects, they are easily washed away by tears, so frequent eye drops may be required when trying to maintain local pharmacologically active ingredient concentrations for a long time.
- most eye drops contain preservatives to prevent the growth of microorganisms, but preservatives tend to cause irritation to the conjunctiva and cornea, and tear fluid during sleep.
- eye drops containing preservatives cannot be used immediately before going to bed because the eye drops are not washed away.
- ophthalmic ointments are as effective as eye drops and the duration of effect is generally increased somewhat compared to eye drops, but it is difficult for the patient to administer for some time after administration. Since the eye ointment covers the tear film, the objects appear blurred and the edges of the eyelids are sticky.
- a transdermal therapeutic system comprising a support layer and a pressure-sensitive adhesive storage layer made of a polymer material containing pilocarpine has been proposed as one of the new attempts regarding the form of an external medicine for ophthalmology.
- Patent Document 1 In this system, this is applied to the skin surface, and pilocarpine is absorbed through the skin and placed on the bloodstream of the whole body, and then transferred to the eye through this.
- drug delivery to the posterior ocular tissue such as the lens, vitreous body, choroid, retina, etc., which is generally difficult to reach pharmacologically active components by instillation or subconjunctival injection, and ensuring patient compliance.
- an ophthalmic transdermal absorption patch characterized by having a drug-containing layer comprising a drug and a transdermal absorption accelerator homogeneously contained in a base matrix has been proposed (patented) Reference 2).
- Patent Document 3 a method using a transdermal patch or pad has been proposed.
- the therapeutic agent for ophthalmic diseases can be transcutaneously transferred to the external ocular tissue such as the conjunctiva, tear tissue, cornea, etc. in a relatively short time, and the drug effect can be exerted continuously.
- a transdermal preparation for treatment of eye diseases has been proposed in which a plaster layer containing a drug is provided on a support and is applied to the skin surface including the front surface of the eyelid (Patent Document 4).
- Patent Document 4 a plaster layer containing a drug is provided on a support and is applied to the skin surface including the front surface of the eyelid.
- a cloth or some other support is indispensable for supporting the drug-containing layer and is supported throughout the administration of the drug.
- the body must be left on the skin.

- the drug concentration in the conjunctiva of the contralateral eye was consistently on the order of 0.:gZg, and there was no significant fluctuation.
- the plasma drug concentration dropped from 0.046 / z gZml after 4 hours of application to 0.017 g / ml after 24 hours and 0.030 ⁇ g / m after 8 hours.
- Table 13 is data showing the concentration of ketotifen fumarate in the conjunctiva when ketotifen fumarate (0.967WZV%) is applied to rabbit eyes (source: 14C ketotifen fumarate instillation). It shows the ability to migrate to the rabbit eye tissue after administration (Shinichi Ota, Clinical Medicine No. 4-11 (1988)).
- Figure 9 shows that the drug concentration in the conjunctiva can be maintained over a very long period of more than 24 hours when administered a solid drug (10 applications), as opposed to ophthalmic administration. Yes.
- the simulation graph for a single application of the solid preparation shows a sustained drug concentration in the conjunctiva that is significantly longer than that for instillation even when the solid preparation is applied only once. It shows that it is obtained.
- ketotifen fumarate is weighed, isopropyl myristate and polyoxyethylene ether are mixed and stirred thoroughly. Add beeswax to this and add about 75
- ketotifen fumarate In a beaker in which ketotifen fumarate is weighed, add isopropyl palmitate and polyoxyethylene glycol ether, stir well, add lauryl alcohol and mix well. Add petrolatum to this and mix well at about 60 ° C. Then, it is poured into a predetermined mold little by little and solidified to obtain a solid medicine.
- the present invention can be used to provide a novel form of an external ophthalmic drug having excellent characteristics when a physiologically active substance can be continuously supplied to ocular tissue for a long time. be able to.
