Description

本発明は、2種類以上(複数種類)の薬剤を混合して乳化液剤又は懸濁液剤を調製する方法およびそれに用いる混合機器に関するものである。   The present invention relates to a method for preparing an emulsion or suspension by mixing two or more (plural types) drugs and a mixing device used therefor.

2種類以上(複数種類)の薬剤を混合して乳化液剤又は懸濁液剤を調製する方法としては、大別して機械的(物理的)方法及び化学的方法の2種類が挙げられる。そのうち機械的方法には、用いる機器により、攪拌法、超音波法、振動法、滴下法、パンピング法などの手法がある。シリンジを用いたパンピング法は、高圧ホモジナイザー、ミル、ミキサーなど大掛かりな機器を必要としないこと、また小容量での調製において比較的薬液の損失が少ないことなどの利点から、簡便に乳化液剤又は懸濁液剤を調製できる方法として研究、臨床現場において汎用されている。
従来のパンピング法は、用時に2種類の薬剤を2本のシリンジにそれぞれ分取し、三方活栓やダブルハブニードル等の接続器具で2本のシリンジの筒先どうしを接続したのち、手動で交互にパンピングして内容物を往復移動させることにより、乳化液剤又は懸濁液剤を混合調製するものであった(例えば、特許文献1参照)。また、2本のシリンジの接続部に多孔体を設けることにより粒子径の均一なエマルションを生成するデバイスも考案されている(例えば、特許文献2参照)。
As a method for preparing an emulsified liquid or suspension by mixing two or more kinds (plural kinds) of drugs, there are roughly classified two types, a mechanical (physical) method and a chemical method. Among the mechanical methods, there are methods such as a stirring method, an ultrasonic method, a vibration method, a dropping method, and a pumping method depending on the equipment to be used. The pumping method using a syringe does not require a large-scale device such as a high-pressure homogenizer, a mill, or a mixer, and has an advantage such as a relatively small loss of chemical solution in preparation with a small volume. It is widely used in research and clinical settings as a method for preparing suspensions.
In the conventional pumping method, two types of medicines are dispensed into two syringes at the time of use, and the syringe tips of the two syringes are connected with connecting devices such as three-way stopcocks and double hub needles, and then manually and alternately. The emulsified liquid or suspension was mixed and prepared by pumping and reciprocating the contents (see, for example, Patent Document 1). A device has also been devised that generates an emulsion having a uniform particle size by providing a porous body at the connecting portion of two syringes (see, for example, Patent Document 2).

実用新案登録第2577239号公報Utility Model Registration No. 2577239 特開2005−186026号公報JP 2005-186026 A

現在、肝癌等の癌の化学塞栓療法などにおいて、2種類以上の薬剤を混合した乳化液剤及び懸濁液剤が使用されている。その際、乳化液剤又は懸濁液剤は、必要となる物性及び使用量が患者毎に異なっているため、用時に患者の状態に合わせて混合調製する必要がある。
上記の器具を用いて薬剤を混合調製する場合には、パンピングを手動で行うため、調製者により回数、速度、圧力といった調製条件が異なり、調製される乳化液剤又は懸濁液剤の物性にばらつきがでるというような問題があった。
この問題を解決すべく、2本のシリンジの接続部に多孔体を設けることにより粒子径の均一なエマルションを生成するデバイスも考案されているが(例えば、特許文献2参照)、手動による操作であることや多孔体の径に限りがあることから、患者の状態に合わせた物性を実現できない問題は依然として残っている。
また、この問題を解決すべく、パンピングを機械的に行うためには、従来のシリンジポンプのように流量が低い機械では、薬剤を混合調製するのに必要な圧入速度が得られず、接続器具で接続した2本のシリンジを交互にスムースにパンピングすることができない。
本発明は、このような問題点に鑑みてなされ、ディスポーザブルシリンジ等、汎用されるシリンジを用いた小容量の乳化液剤又は懸濁液剤の調製において、調製者によらず均一な物性の乳化液剤又は懸濁液剤の調製を達成することを目的とするものである。
Currently, an emulsified solution and a suspension obtained by mixing two or more kinds of drugs are used in chemoembolization for cancer such as liver cancer. At that time, since the required physical properties and the amount of use of the emulsion or suspension differ from patient to patient, it is necessary to prepare a mixture according to the patient's condition at the time of use.
When mixing and preparing drugs using the above equipment, pumping is performed manually, so the preparation conditions such as the number of times, speed, and pressure differ depending on the preparer, and the physical properties of the prepared emulsion or suspension vary. There was a problem of getting out.
In order to solve this problem, a device that generates an emulsion having a uniform particle diameter by providing a porous body at the connection part of two syringes has been devised (for example, see Patent Document 2). There is still a problem that physical properties tailored to the patient's condition cannot be realized because there is a limit to the diameter of the porous body.
In order to solve this problem, in order to perform the pumping mechanically, a machine with a low flow rate such as a conventional syringe pump cannot obtain the press-fitting speed necessary for mixing and preparing the drug, and the connecting device The two syringes connected with can not be pumped smoothly alternately.
The present invention has been made in view of such problems, and in the preparation of a small volume emulsion or suspension using a commonly used syringe, such as a disposable syringe, the emulsion having uniform physical properties regardless of the preparation The aim is to achieve the preparation of a suspension.

手動による乳化液剤の調製(比較例1)
ヨード化ケシ油脂肪酸エチルエステル注射液(リピオドールウルトラフルイド、ゲルベ・ジャパン株式会社)5mLをディスポーザブルシリンジ(テルモシリンジ、10mL、テルモ株式会社)にとり、非イオン性造影剤(オムニパーク240、第一三共株式会社)5mLをディスポーザブルシリンジ(テルモシリンジ、5mL、テルモ株式会社)にとった。2本のシリンジを三方活栓(テルフュージョン、テルモ株式会社)でL字型に接続した。被験者10名につき、両手で交互に30回パンピングを行い、乳化液剤を作製した。得られた乳化液剤の粒度分布を粒度分布測定装置(LS230、ベックマン・コールター株式会社)で測定し、最頻径(単位:μm)を求めたところ、下記の表3に示すとおりであった。
Manual preparation of emulsified liquid (Comparative Example 1)

上述の通り、薬剤混合機器を使用した試験例1〜3(表2)及び手動で行った比較例1(表3)について、得られた乳化液剤の粒度分布を粒度分布測定装置で測定し、最頻径を求めた。その結果、パンピング回数を30回に設定したとき、薬剤混合機器を使用した試験例1〜3では、最頻径の標準偏差が0.00〜1.40であったのに対し、手動で行った比較例1では6.92であった。薬剤混合機器を使用する場合には、パンピングの速度・圧力が一定であるため、従来のパンピング法で見られた最頻径のバラツキの問題は起こりにくい。
一定の調製精度が求められる乳化液剤や懸濁液剤にとって、薬剤混合機器を用いた調製方法は有用なシステムであると考える。
As described above, for Test Examples 1 to 3 (Table 2) using a drug mixing device and Comparative Example 1 (Table 3) performed manually, the particle size distribution of the obtained emulsion was measured with a particle size distribution measuring device, The mode diameter was determined. As a result, when the number of pumping was set to 30 times, in Test Examples 1 to 3 using the drug mixing device, the standard deviation of the mode diameter was 0.00 to 1.40. In Comparative Example 1, it was 6.92. When using a drug mixing device, the pumping speed and pressure are constant, so the problem of the variation in the mode diameter found in the conventional pumping method is unlikely to occur.
For emulsions and suspensions that require a certain level of preparation accuracy, the preparation method using a drug mixing device is considered a useful system.
