The present invention relates to a stable emulsion of a fat-soluble drug prepared using lecithin and ethanol. Conventionally, solubilized preparations containing large amounts of nonionic surfactants have been frequently used as liquid preparations for fat-soluble drugs, but recently the side effects of synthetic surfactants on the human body have become a problem. Therefore, the present inventors attempted to produce an emulsion-type preparation using lecithin, which is a natural substance and has relatively high safety, instead of a synthetic surfactant. As an example of emulsifying a fat-soluble drug using lecithin, there is an example of emulsifying gefalnate with lecithin (Japanese Unexamined Patent Application Publication No. 1989-1999).
126821), and an example in which vitamin E or its ester is emulsified using lecithin and vegetable oil (Japanese Patent Application Laid-Open No. 49-50124). but,
When emulsifying fat-soluble drugs using these methods, a special device called a pressure emulsifier is required because the emulsifying power of lecithin is weak, and the long-term stability of the resulting emulsion is not sufficient. . As a result of research to produce a more stable emulsion of fat-soluble drugs, the present inventors discovered that by dissolving lecithin and fat-soluble drugs in ethanol and emulsifying this solution by adding it to water, a stable emulsion can be obtained. He discovered that this could be done and completed the present invention. JP-A-49-50124 discloses that lecithin is used after being dissolved in ethanol in some cases, but this is different from the structure of the present invention. While this method uses vegetable oil as an essential component and ethanol is optionally distilled off before emulsification, the present invention does not use vegetable oil and does not remove ethanol to the end. It was shown in Example 2 below that when vegetable oil is further added when producing an emulsion of a fat-soluble drug using lecithin and ethanol, the stability of the emulsion worsens. The present invention provides 1 part by weight of a fat-soluble drug and lecithin.
An emulsion of a fat-soluble drug is obtained by dissolving 0.1 to 10 parts by weight in 1 to 50 parts by weight of ethanol, and then adding this to water to emulsify. Furthermore, from the viewpoint of stability of the emulsion, a particularly preferred blending ratio of each component is 0.2 to 3 parts by weight of lecithin and 5 to 20 parts by weight of ethanol per 1 part by weight of the fat-soluble drug. Examples of the fat-soluble drugs of the present invention include phytonadione (vitamin K 1 ), menatetrenone (vitamin K 2 ), coenzyme Q analogues, tocopherols and their derivatives, and gefalnate. Further, as the lecithin, either soybean lecithin or egg yolk lecithin may be used. In the present invention, when a solution of a fat-soluble drug and lecithin dissolved in ethanol is added to water and emulsified, high shear force is applied using a pressurized emulsifier, which is used in conventional emulsification using lecithin. Emulsification below is not necessary, and a sufficiently stable emulsion can be obtained by ordinary stirring emulsification. When performing stirring emulsification in the present invention, instead of simply adding the ethanol solution of the fat-soluble drug and lecithin to water, if a method is adopted in which the ethanol solution is injected under pressure into water through a tube, stable emulsification with finer particle size can be achieved. liquid can be obtained. Further, a part of the lecithin used in the present invention may be dissolved in water in advance and emulsified. In the production of the emulsion of the present invention, isotonic agents, buffers, solubilizing agents, other emulsifiers, flavoring agents, flavoring agents, preservatives, stabilizers, etc. can be further added as appropriate. . The emulsion of the present invention usually has an average of 0.5
It consists of fine emulsified particles with a diameter of less than μ, can withstand heat sterilization, and has excellent physical stability over time. EXAMPLES Next, the present invention will be explained in more detail with reference to Examples. Example 1 Fat-soluble drugs shown in the table, lecithin, ethanol,
Other additives were dissolved by heating on a water bath at 55-60°C. This was added to distilled water for injection containing 5% glucose heated to the same temperature and emulsified to make a total volume of 100 ml. Emulsification was carried out for samples 1 to 5 of the present invention by injecting the oil phase into the aqueous phase under pressure and treating it for 5 minutes at 300 rpm using a propeller stirrer, and for control samples 6 to 10, the oil phase and the aqueous phase were mixed at TK. The treatment was carried out using a homomixer (trade name, Tokushu Kika Kogyo KK) at 4000 rpm for 10 minutes. The resulting emulsion was passed through a Millipore filter. After dispensing the liquid into ampoules and melting them, heat them to 100℃.
sterilized by heating for 60 minutes. The emulsion obtained by the above method and the emulsion left at room temperature for 6 months were observed with the naked eye (appearance) and the particle size was observed with an electron microscope. As shown in the table below, the emulsion of the present invention has better stability than the control.

た。結果を次の表に示す。[Table] In the formulation of the present invention and the formulation of Control 2, vitamin E acetate, ethanol, egg yolk lecithin, and soybean oil (Control 2 only) were dissolved by heating at 55 to 60°C, and this was dissolved in glycerin at the same temperature. The mixture was injected into distilled water for injection under pressure and stirring (300 rpm) to emulsify. Controls 1 and 3 formulations contain vitamin E
Egg yolk lecithin or an ethanol solution of egg yolk lecithin was added to a mixture of acetate and soybean oil, and for Control 1, the ethanol was distilled off under reduced pressure at 50°C or less, and then stirred into distilled water for injection in which glycerin had been dissolved. Coarsely emulsify with a homo mixer, and use a Manton Gaulin pressure emulsifier to
Emulsified under pounds of pressure. Each emulsion obtained was filtered through a Mia Poly filter, dispensed into ampoules and melted, and then heated at 100℃ for 60 minutes.
Heat sterilized for minutes. The state of each emulsion immediately after production,
and the stability after storage at room temperature or 40°C was investigated. The results are shown in the table below.

剤とした。[Table] Example 3 Menatetrenone 4g Purified soybean lecithin 1g Ethanol 36g Macrogol 400 50g Glucose 50g Distilled water for injection Total volume 1000ml Menatetrenone , purified soybean lecithin, ethanol, and Macrogol 400 were heated and dissolved in a water bath at about 60°C to make an oil. It was a phase. In addition, glucose was dissolved in distilled water for injection and heated to about 60°C to form an aqueous phase. The oil phase was injected into the water phase under pressure and stirring (300 rpm) to emulsify it. The emulsion was filtered through a Millipore filter, dispensed into ampoules and sealed, and then heat sterilized at 100°C for 60 minutes to prepare an injection. Example 4 Natural tocopherol concentrate (soybean origin) 10 g Egg yolk lecithin 1 g Soybean lecithin 2 g Ethanol 40 g Propylene glycol 30 g Ethylparapen 0.5 g Purified water Total volume 1000 ml Natural tocopherol concentrate, egg yolk lecithin, ethanol, propylene glycol was dissolved by heating on a water bath at about 60°C to form an oil phase. On the other hand, soybean lecithin and ethyl paraben were dissolved in purified water and heated to about 70°C to form an aqueous phase. The oil phase was injected into the water phase under pressure and stirring (300 rpm) to obtain an emulsion. This emulsion is preferable as a food additive formulation of natural tocopherols.

On the other hand, xylitol was dissolved in distilled water for injection and heated to about 45°C to form an aqueous phase. Stirring the oil phase into the water phase (300 rpm)
was injected under pressure to emulsify. 0.1N sodium hydroxide was added to the emulsion to adjust the pH to 6.0. Then,
The mixture was passed through a Millipore filter, dispensed into ampoules and melted, and then heat sterilized at 100°C for 60 minutes to prepare an injection.
