Definitions
- the present invention relates to a pharmaceutical aqueous composition containing sodium cromoglycate, which is an antiallergic agent, as an active ingredient and useful for eye drops, injections, and the like.
- aqueous compositions in the form are used for the prevention and treatment of allergic conjunctivitis and allergic rhinitis.
- aqueous pharmaceutical compositions containing sodium cromoglycate as an active ingredient are extremely susceptible to turbidity and precipitation (see, for example, Japanese Patent Publication Nos. 4-66452 and 4-78613). ).
- the reason for this turbidity or precipitation is that quaternary ammonium compounds such as benzalkonium chloride added as a preservative cause trace amounts of metal ions (Pb 2+ , Ca 2+ , Cu 2+ , A +, It is thought to be due to the reaction with sodium cromoglycate in the presence of Fe 2 + , Fe 3 + , Zn 2 + , Mg 2 +, etc.).
- a precipitation inhibitor such as a chelating agent (sequestering agent) or a nonionic surfactant is used as a means for effectively preventing the formation of precipitation and turbidity.
- a precipitation inhibitor such as a chelating agent (sequestering agent) or a nonionic surfactant.
- aqueous composition containing sodium cromoglycate as an active ingredient
- concentration of gold ion in an aqueous solution exceeds 0.40 ppm
- a pharmaceutically acceptable chelating agent or sequestering agent Asilable in Japanese Patent Publication No. 54-25082
- benzalkonium chloride a preservative
- polyoxetylenelenurbitan monooleate or polyoxy an agent for preventing turbidity or precipitation.
- a water-soluble formulation containing schillen-hardened castor oil (JP-B 4-66452); and a non-ionic surfactant such as benzalkonium chloride as a preservative and a polyoxetylene-hardened castor oil.
- a non-ionic surfactant such as benzalkonium chloride as a preservative and a polyoxetylene-hardened castor oil.
- An object of the present invention is a pharmaceutical aqueous composition containing sodium cromoglycate as an active ingredient, which is useful as an ophthalmic solution or an injection, which does not cause precipitation or turbidity during production and storage or distribution. It is to provide a stable composition.
- the present invention relates to an aqueous pharmaceutical composition
- an aqueous pharmaceutical composition comprising sodium cromoglycate as an active ingredient and a quaternary ammonium compound as a preservative, and comprising a precipitate selected from the group consisting of alkanolamines and tocopherols. It is intended to provide a composition characterized by containing an inhibitor.
- a compound selected from the group consisting of alcohol amines and tocoproles Provided is an anti-settling agent to be incorporated into an aqueous pharmaceutical composition comprising sodium molycate and a quaternary ammonium compound as a preservative.
- Sodium cromoglycate contained in the aqueous composition of the present invention [Chemical name: 1,3-bis (2-carboxychromone-5-yloxy) -2-hydroxypropane] dinatridium salt or disodium-5,5 '-[ (2-Hydroxytrimethylene) dioquin] bis [4-oxo-4 ⁇ -1-benzopyran-2-carboxylate] is widely used as an active ingredient in recruitment and eye drops for allergic diseases of the eye. .
- the concentration is generally about 1.5 to 4.0% by weight.
- benzalkonium chloride or benzethonium chloride can be used as the quaternary ammonium compounded as a preservative. Of these, it is preferable to use benzalkonium chloride from the viewpoint of antibacterial activity.
- Benzalkonium chloride is a compound represented by the general formula [C 6 H 5 CH 2 N (CH 3 ) 2 ] + CI ", and the alkyl group represented by R in the above general formula generally has a carbon number of 8 to 18 it. the compound will generally have been provided as a mixture of compounds having a C 8 ⁇ 8 alkyl group, a specific mixture consisting of compounds or compound having a specific alkyl group having a specific alkyl group may be used.
- the concentration of the preservative is not particularly limited as long as it is within the range generally used for aqueous pharmaceutical compositions. . 0 It is preferably about 0.01 to 0.05% by weight.
- the aqueous composition containing sodium chromoglycate and the quaternary ammonium compound as a preservative is selected from the group consisting of alkanolamines and tocofurols as a suspending agent. Or, it is characterized by combining two or more substances.
- the term sedimentation inhibitor refers to the formation of precipitates, such as macroscopically observable white turbidity, as well as macroscopic and Z or spectroscopic observations. It should be understood that it has the effect of reducing and suppressing possible increase in turbidity.
- precipitation and “turbidity” should be understood as the broadest concepts, including those that occur during the mixing and subsequent manufacturing processes of components and those that occur during storage and distribution of final products. Although not wishing to be bound by any particular theory, such precipitation and turbidity are caused by the reaction of the quaternary ammonium compound with sodium cromoglycate in the presence of trace amounts of metal ions contained in the aqueous solution. It is believed to be something.
- An alkanolamine is a compound having a structure in which one or two or more hydroxyl groups and one or two or more amino groups are substituted at any position of a linear or branched alkane having 2 to 12 carbon atoms.

- alkanolamines a pure form of an optically active substance or a diastereoisomer, an arbitrary mixture thereof, or a racemic substance can be used.
- alkynolamines in the form of a pharmacologically acceptable acid addition salt may be used.
- mineral salts such as hydrochloride, sulfate, nitrate, and phosphate
- organic acid salts such as citrate, malate, oxalate, tartrate, and methanesulfonate can be used.
- tocopherols ⁇ , ⁇ , ⁇ , and (—tocopherol or any mixture thereof can be used.
- tocopherol is blended in foods and medicines as an antioxidant and has an antioxidant effect.
- a tocopherol derivative which is substantially equivalent to tocopherol can be used, and such derivatives include, for example, sodium tocopheryl acetate and sodium succinate tocopheryl acid.
- Derivatives may be used as suspending agents ..
