Definitions
- the present invention relates to a ribosome produced using a saccharide and a method for producing the ribosome. More specifically, the present invention relates to a minute ribosome produced using a high concentration of saccharide, and a method for producing the same. Background art
- a ribosome is a closed packet of lipids, and is used to intentionally direct a drug encapsulated inside the packet to a specific site in the body, and to ensure the stability and sustainability of release of the drug. ing.
- the particle size is an important factor in pharmacokinetics, and is deeply related to, for example, disappearance from the blood circulatory system, distribution to tissues, absorption by organs, and transfer between tissues. In order to perform these operations smoothly, fine particles are preferable. Also, by reducing the particle size, the filtration required for injections and sterilization by filtration can be performed. Thus, the particle size is an important factor in injectable preparations.
- Conventional methods for producing ribosomes often include a first step of hydrating and swelling a phospholipid in an aqueous dispersion medium and a second step of miniaturizing to obtain a desired particle size.
- Various ideas have been devised in the step.
- the solvent is distilled off from a solution in which the lipid is dissolved in a volatile organic solvent, a thin film made of lipid or the like is formed on the inner wall of the container, an aqueous dispersion medium is added and stirred, and the lipid thin film is formed.
- a method of hydrating and swelling Although this method is relatively simple, the ribosome after hydration and swelling is a multilayer packet, and its particle size is relatively large, about several to several hundred microns. Therefore, when it is necessary to reduce the particle size to a small particle size of an injection or the like, a miniaturization step is required.
- Methods for the second step of miniaturization of liposomes and uniformization of particle size distribution include, for example, extrusion using a polycarbonate filter, high-pressure emulsification, and ultrasonic irradiation (see Ribosome (Nan-Edo, 1988)). . If the hydrated ribosomes before micronization have a large particle size, the ribosome dispersion may be repeatedly passed through the same size of polycarbonate filter (see Patent No. 2537186 (W ⁇ )). 860 238, EP 185 57 56) Refer to the specification), emulsification at high pressure and extension of ultrasonic irradiation time are required, and the production time and the size of production equipment become problematic.
- surfactant removal method for example, well-known methods include (1) surfactant removal method and organic solvent injection method (see Ribosome (Nankodo, 1988), Manual for liposome experiments in life sciences (Springer Fairlark Tokyo, 1992)).
- the surfactant removal method is known as a method for obtaining minute ribosomes by solubilizing lipid with a surfactant and then removing the surfactant.
- an apparatus for removing the surfactant is required, and the processing time becomes a problem.
- the organic solvent injection method involves dissolving lipids in a water-soluble organic solvent such as ethanol and injecting the solution into an aqueous dispersion medium.
- a water-soluble organic solvent such as ethanol
- This method is easy to hydrate, and is a method for producing minute liposomes.
- the particle size of the liposome obtained by this method greatly depends on the concentration of the lipid solution, and a finer ribosome can be obtained by making the lipid solution more dilute. However, diluting the lipid solution inevitably increases the amount of organic solvent used.
- each method has various problems, and the reduction in the particle size of the liposome after hydration is not sufficient.
- the main purposes of adding these are (1) tonicity when used as an injection, (2) retention of ribosome form during lyophilization, or (3) to use as a core substance when forming lipid thin films. is there.

- Ribosome technology (edited by Gregory Gregoriadis, LIPOSOME TECHNOLOGY, Vol. I, 2nd Edition, 229-252 (published in 1993)) examined the effects of various sugars on the retention of ribosome shape during freeze-drying. ing.
- Japanese Patent Publication No. 3-69669 discloses that the characteristics of liposome preparations can be improved by freeze-drying using a saccharide as an excipient, and the saccharide concentration during production is 1 to 10%. %a.
- Japanese Patent Publication No. 5-51338 (EP 1 19020) The specification describes a method of coating a water-soluble granular carrier substance with a ribosome thin film, and the carrier substance includes sorbitol, mannitol, xylitol, naturally occurring amino acids, ! Sucrose, dextrose and sucrose. It is stated that an isotonic aqueous solution having a concentration of about 1 to 10 W / V, preferably about 3 to 7% WZV should be formed.
