Abstract

Sustained release preparations for injection characterized by containing medicinally active ingredients, fibrinogen, blood-coagulation factor 13 thrombin and gabexate mesylate; and kits for preparing the same at the time of use. When processed into aqueous solutions for injection, these preparations do not immediately coagulate at room temperature. After injection, they rapidly gel or solidify in vivo and thus form fibrin clots followed by the sustained release of the drugs encapsulated therein. Thus, these preparations are fibrin clot forming agents which can be easily injected without requiring any special technique.

More specifically, the present invention relates to a sustained-release preparation for injection containing a pharmaceutically active ingredient, fibrinogen, blood coagulation factor 13, thrombin and gabexate mesylate, and a kit for preparing the same at the time of use. They are particularly suitable for administering proteinaceous drugs subcutaneously or intramuscularly.

It has been reported.

Here, as an in vitro test, an equal amount of solution A (aprotinin solution containing fibrinogen, blood coagulation factor 13) and solution B (calcium chloride solution containing thrombin) were mixed. The IL-2 Fibrin preparation prepared above was solidified to study sustained release.The ratio of fibrinogen to thrombin used was 80 mg of fibrinogen and 2 for thrombin. 50 units. In the in vivo test, the solution A and the solution B were separately administered subcutaneously to mice using two syringes. Japanese Patent Application Laid-Open No. Hei 6-333644 discloses a sustained-release pharmaceutical composition containing fibrinogen and fibrin or fibrin. The applied drug is a fat-soluble drug, and an anionic surfactant is essential as an additive. Furthermore, the blending ratio of fibrinogen and thrombin when preparing fibrin is such that thrombin is 30 to 500 units per 80 mg of fibrinogen. Japanese Patent Application Laid-Open No. 7-41432 discloses a sustained-release pharmaceutical composition in which drug-encapsulated ribosomes or lipid microspheres are uniformly dispersed in fiprinogen or fiprin. . The blending ratio of fibrinogen to thrombin in preparing fibrin is such that thrombin is 120 to 2000 units per 8 O mg of fibrinogen.
このように、 フイ ブリ ンクロッ ト形成機構を利用した従来の徐放化製剤では、 フィ プリ ノーゲンに対する トロンビンの配合比率が相対的に高く、 典型的には、 例えばフイ ブリ ノ一ゲン 8 0 m gに対してトロンビンが約 2 5 0単位の割合であ る。 そのため両成分を混合すると比較的短時間でフイ ブリ ンクロッ 卜が形成され て注射液が凝固してしまうので、 溶液状態のままで投与するのが不可能になる恐 れがある。 そのため、 注射剤として投与する場合には、 薬物、 フイ ブリ ノ一ゲン 及びトロンビンを含有する混合液を調製した後、 注射器へ速やかにセッ トしかつ 瞬時に投与するか、 もしくはフイ ブリ ノ一ゲンを含有する溶液と トロンビンを含 有する溶液とを別々に注射する必要があった。 又, 該両液を、 W O 94/ 1 227号等 に記載の 2液混合型の注射器にセッ トしたとしても、 混合後にはやはり速やかに 投与されなければならない。 即ちこのような現状は、 臨床上の投与操作としては 満足のいく ものではなかった。 よって、 特別な技法を要することなく容易に注射 可能な徐放性製剤またはそれを用時調製するためのキッ 卜の開発が要望されてい る。  As described above, in the conventional sustained-release preparation utilizing the fibrin clot formation mechanism, the mixing ratio of thrombin to fibrinogen is relatively high, and typically, for example, 80 mg of fibrinogen is used. On the other hand, thrombin accounts for about 250 units. Therefore, when the two components are mixed, a fibrin clot is formed in a relatively short time and the injection solution solidifies, so that it may be impossible to administer the solution in a solution state. Therefore, when administering as an injection, a mixed solution containing the drug, fibrinogen and thrombin is prepared, and then immediately set in a syringe and administered immediately, or the fibrinogen is used. And the solution containing thrombin had to be injected separately. Also, even if the two solutions are set in a two-component syringe described in WO 94/1227, etc., they must still be administered immediately after mixing. That is, this situation was not satisfactory as a clinical administration operation. Therefore, there is a demand for the development of a sustained-release preparation which can be easily injected without requiring any special technique, or a kit for preparing the same at the time of use.

該医薬活性成分の配合量は、 その種類、 対象疾患、 患者の状態、 投与回数等を 考慮の上、 適宜設定すればよい。  The amount of the pharmaceutically active ingredient may be appropriately set in consideration of the type, target disease, patient condition, number of administrations, and the like.
本発明製剤は生体内に投与されると、 活性化された トロンビンがフィ プリ ノ一 ゲンに作用してフイブリ ンモノマー. 次いでフイ ブリ ンポリマーを形成し、 それ がカルシウムイオン存在下、 血液凝固第 1 3因子により架橋 (cross- 1 inking) されて最終的に医薬活性成分を一部又は全部取込んだ形でフィ ブリ ンクロッ 卜が 形成される。 その後、 薬物がクロッ ト内から徐放出されることにより、 薬効の持 統化が達成される。  When the preparation of the present invention is administered to a living body, the activated thrombin acts on fibrinogen to form a fibrin monomer. Then, a fibrin polymer is formed. The agent is cross-linked by a factor, and finally a fibrin clot is formed in a form incorporating a part or all of the pharmaceutically active ingredient. Thereafter, sustained release of the drug from the clot achieves sustained efficacy.
メシル酸ガべキサートは、 本発明製剤が水溶液として調製された後、 生体内に 投与されるまでの間にフイ ブリ ンクロッ トを形成し凝固してしまうのを防止する。 その添加量は、 内包する医薬活性成分の種類や目的とする徐放化の度合い、 トロ ンビンの配合量等により異なり一概には規定しにく いが、 本発明製剤においては 通常、 フイ ブリ ノ一ゲンが 8 0 m gに対してメシル酸ガべキサートが約 0. 0 5 〜3 0 mg、 好ましくは約 0. 5〜1 0mg、 更に好ましくは約 l ~ 1 0mg、 とりわけ約 1 ~ 5 mgに相当する比率である。 メシル酸ガべキサー 卜の添加量が 多すぎる場合には、 トロンビン配合量を比較的少なく設定した本発明製剤におい て、 生体内投与後のフイ ブリ ンクロッ ト形成が遅延し, その結果、 内包薬物の大 部分がクロッ 卜が形成される前に投与部位から急激に拡散、 放出されてしまうの で、 薬効の持続化を達成するのが困難となる。 一方、 メ シル酸ガべキサー トの添 加量が少なすぎると、 トロンビン配合量を比較的多く設定した本発明製剤におい て、 水溶液中における トロンビンの作用を抑制するのが不十分となり、 その結果、 該水溶液を注射器にセッ 卜 して生体内に投与するまでに十分な時間が確保されな い。 よって、 慎重な薬物投与が出来ないばかり力、、 場合によっては注射液が投与 前に注射器内で凝固してしまい投与不可能な事態に陥る。 Gabexate mesylate prevents the formation and coagulation of fibrin clot between the time when the preparation of the present invention is prepared as an aqueous solution and the time when the preparation is administered in vivo. The amount added depends on the type of the contained pharmaceutically active ingredient, the intended degree of sustained release, the amount of thrombin, and the like, and is generally difficult to define. However, in the preparation of the present invention, fibrino is usually used. Gabexate mesylate is used in an amount of about 0.05 to 30 mg, preferably about 0.5 to 10 mg, more preferably about 1 to 10 mg, and particularly about 1 to 5 mg per 80 mg of a gene. Is the ratio corresponding to When the amount of gabexate mesylate added is too large, fibrin clot formation after in vivo administration is delayed in the preparation of the present invention in which the amount of thrombin is set to a relatively small amount. Most of these are rapidly diffused and released from the site of administration before the clot is formed, making it difficult to achieve sustained efficacy. On the other hand, the addition of gabexate mesylate If the addition amount is too small, it becomes insufficient to suppress the action of thrombin in the aqueous solution in the preparation of the present invention in which the blending amount of thrombin is set relatively large, and as a result, the aqueous solution is set in a syringe and produced. Insufficient time to administer to the body. As a result, careful administration of the drug is not possible, and in some cases, the injection solution solidifies in the syringe before administration and the injection becomes impossible.
またトロンビンの配合量との関係でメシル酸ガべキサー トの好ましい添加量を 規定するならば、 例えばトロンビン 3単位に対し約 0 . 1〜 3 m g、 トロンビン 3 0単位に対し約 2 ~ 8 m gである。  If the preferred amount of gabexate mesylate is specified in relation to the amount of thrombin, for example, about 0.1 to 3 mg for 3 units of thrombin and about 2 to 8 mg for 30 units of thrombin It is.
フイ ブリ ノ一ゲンに対する トロンピンの配合比率は、 内包する医薬活性成分の 種類、 目的とする徐放化の度合い、 メシル酸ガべキサー トの配合量等に応じて適 宜設定すればよいが、 通常、 フイ ブリ ノ一ゲンが 8 0 m gに対して トロンビンが 約 1 〜 3 0 0単位、 好ましくは約 1 〜 3 0単位、 より好ましくは約 1 から 1 0単 位、 例えば 3単位である。 トロンビンの配合量が多すぎるとメシル酸ガべキサー 卜の効きが鈍くなつて、 投与前の注射溶液がクロッ トを形成するのを制御できな くなる恐れがある。 一方、 トロンビンの配合量が少なすぎると、 生体内投与後の クロッ 卜形成が遅くなり、 十分な徐放化が達成されない恐れがある。  The mixing ratio of thrompine to fibrinogen may be appropriately set according to the type of the contained pharmaceutically active ingredient, the intended degree of sustained release, the amount of gabexate mesylate, and the like. Usually, thrombin is used in an amount of about 1 to 300 units, preferably about 1 to 30 units, more preferably about 1 to 10 units, for example, 3 units per 80 mg of fibrinogen. If the amount of thrombin is too large, the effectiveness of gabexart mesylate may be reduced, and it may be impossible to control the clot formation of the injection solution before administration. On the other hand, if the amount of thrombin is too small, the clot formation after in vivo administration may be delayed, and sufficient sustained release may not be achieved.
血液凝固第 1 3因子の配合比率は、 通常、 フイ ブリ ノ一ゲンが 8 0 m gに対し て約 0 . 0 5〜 1 0 0単位、 好ましく は約 0 . 1 〜 8 0単位、 更に好ましくは約 0 . 2 5〜 6 0単位である。 血液凝固第 1 3因子の配合量が多い分には特に支障 はないと考えられる力 少なすぎるとフイ ブリ ンクロッ トが軟らかくなり、 薬物 の徐放出性に悪影響を及ぼすので好ましくない。  Usually, the mixing ratio of blood coagulation factor 13 is about 0.05 to 100 units, preferably about 0.1 to 80 units, more preferably about 0.1 to 80 units per 80 mg of fibrinogen. Approximately 0.25 to 60 units. It is considered that there is no particular problem with a large amount of the blood coagulation factor 13 if the amount is too small, the fibrin clot becomes too soft and adversely affects the sustained release of the drug.
本発明製剤においては、 任意にカルシウムイオンが含有され得る。 本発明製剤 が生体内に投与された後、 フイ ブリ ンクロッ トが形成されるためには、 カルシゥ ムイオンの存在が必須であるが、 該カルシウムイオンは生体内にも存在するので あらかじめ製剤成分として含有しない場合でも、 フイ ブリ ンクロッ 卜は形成され 得る。 あらかじめ製剤成分としてカルシウムイオンを含有しておく場合のカルシウム イオンの配合比率は、 通常、 フイブリ ノ一ゲン 8 O m gに対して約 5〜 2 0 0 m m 0 1 , 好ましくは約 1 0〜1 0 0 01111 0 1 、 より好ましくは約 3 0〜 7 0 m m o 1 に相当する比率である。 該カルシウムイオンは、 例えば塩化カルシウム等の 製薬上許容されるカルシウム塩として配合され得る。 The preparation of the present invention may optionally contain calcium ions. In order for fibrin clots to be formed after the preparation of the present invention is administered in vivo, the presence of calcium ions is essential. If not, a fibrin clot can be formed. When calcium ions are contained in advance as a formulation component, the mixing ratio of calcium ions is usually about 5 to 200 mm 01, preferably about 10 to 10 mm for 8 O mg of fibrinogen. 0 01111 0 1, more preferably a ratio corresponding to about 30 to 70 mmo 1. The calcium ion can be formulated as a pharmaceutically acceptable calcium salt such as calcium chloride.

産業上の利用可能性 Industrial applicability
本発明製剤は、 水溶液に調製しても室温ではすぐには凝固しないが、 注射投与 後には、 体内で速やかにゲルまたは固体状態になってフィブリンクロッ トを形成 する。 フイブリンクロッ ト中に内包された医薬品は、 クロッ トの分解に伴って体 内で徐々に放出される。 徐放出は頻回投与を削減でき、 又組織中で薬物濃度を一 定の水準に維持することも可能である。 即ち、 本発明製剤を用いることによって 注射投与の操作自体が容易になる上、 医薬品の薬効作用の増強も期待できる。 ま た、 急激な組織中濃度の上昇を抑制することにより副作用の低減も期待できる。 また、 本発明キッ トを用いることにより、 本発明製剤を容易に用時調製できる。  The formulation of the present invention does not immediately coagulate at room temperature even when prepared into an aqueous solution, but after injection administration, it rapidly becomes a gel or solid state in the body to form a fibrin clot. Drugs contained in the fibrin clot are gradually released in the body as the clot decomposes. Slow release can reduce frequent dosing and can also maintain a constant drug concentration in the tissue. That is, the use of the preparation of the present invention facilitates the injection administration itself, and can be expected to enhance the pharmacological effect of the drug. In addition, reduction of side effects can be expected by suppressing the rapid increase in tissue concentration. Further, by using the kit of the present invention, the preparation of the present invention can be easily prepared at the time of use.
