Definitions
- the present invention relates to a catheter lock solution having a bacteriostatic effect, which is a solution injected into the lumen of a catheter placed in a patient's blood vessel, and a container containing the lock solution.
- In-hospital infection is an important issue to be solved in modern medicine because it threatens the lives of patients, and for hospitals, in addition to extending the length of hospitalization, it spends excessive medical expenses.
- the route of nosocomial infection is mainly (1) drug contamination at the time of drug preparation and (2) contamination of the drug administration route.
- (1) a pre-filled preparation is used to reduce the chance of drug contamination, or (2) the flow path is closed to reduce the contamination of the administration route.
- a medical device has been developed.
- An intravascular catheter is a tube that is inserted into a blood vessel in order to administer an infusion preparation or drug into the blood.
- peripheral venous catheters and central venous catheters are frequently used as access to blood vessels, and these catheters are representative examples of vascular indwelling catheters.
- This intravascular catheter is regarded as a problem as a source of nosocomial infection. For example, local infection by an intravascular catheter, bloodstream infection, sepsis or the like is caused.
- Various measures have been taken such as the establishment of a guideline (the following Non-Patent Document 1) as a countermeasure.
- Catheter lock is a catheter lock solution in which a physiological saline solution or heparin diluted with a physiological saline solution is filled into a catheter and is generally sealed for about 24 hours.
- Most catheter lock solutions use a heparinized diet with anticoagulant action, but physiological saline may be used to lock peripheral venous catheters for a short period of time.
- Placement of a catheter locked with a catheter lock solution in a blood vessel is widely performed because it has advantages such as reducing the frequency of needle sticking to a patient and reducing the labor of a medical worker to insert a catheter.
- Patent Document 1 An injection container filled with a solution containing 1 to 100 units / mL of heparin and containing no physiologically isotonic and preservative having a pH of 6 or more is disclosed (Patent Document 1). Since this catheter lock solution is a sterile preparation that is pre-filled and sold in an injection container, the chance of contamination at the time of in-hospital preparation has decreased, and it is considered that nosocomial infection has been reduced. However, this catheter lock solution, that is, physiological saline and heparin saline, has no antibacterial and bacteriostatic action, and as the data shows later, it grows when bacteria are mixed in, so it is said that the hospital infection was eradicated. It's hard to say.
- Non-Patent Document 3 As heparin preparations having antibacterial activity, products containing methyl paraoxybenzoate, propyl paraoxybenzoate, chlorobutanol, cresol, phenol or benzyl alcohol as preservatives are on the market. However, when benzyl alcohol is administered in a large amount, there are reports that dyspnea and allergic reactions occur (Non-Patent Document 3 below), and the above-mentioned toxic preservatives are no longer used from the viewpoint of safety.
- Non-patent Document 7 a combination of an anticoagulant / antibacterial agent containing the antibiotics minocycline and ethylenediaminetetraacetic acid has been proposed and studied as a catheter lock solution (Non-patent Document 7 below). Further, a concentrated solution of citrate has been disclosed as a catheter lock solution for reducing infection (Patent Document 2 below), but as shown in the Examples, it is very hypertonic 47% citric acid. Bacteremia is improved by the antibacterial action of a salt solution (presumed to be about 6000 mOs). The high concentration citrate lock solution far from the physiological osmotic pressure takes in calcium in the blood to form a complex, and therefore, it is considered that there are safety concerns such as the development of hypocalcemia.

- the inorganic acid or organic acid is preferably one that does not inhibit the medicinal effect of heparin.
- These weak acids can be used singly or in combination, and the combination of the multiple acids can broaden the pH range showing buffer capacity.
- the buffer must have a concentration that maintains its pH even when it comes into contact with blood, and the concentration is about 10 to 250 mM, preferably about 50 to 150 mM.
- the osmotic pressure is made the same as the osmotic pressure of a living body by using an osmotic pressure regulator such as sodium chloride.
- the heparin solution is usually used for applications such as hemodialysis, prevention of blood coagulation when using an oxygenator or other extracorporeal circulation device, prevention of blood coagulation when a vascular catheter is inserted, prevention of blood coagulation during blood transfusion and blood tests, etc.
- the heparin solution used in the above can be used without any particular limitation.

- Example 1 The catheter lock solution was tested for pH and pH buffering capacity and bacterial growth.
- heparin having a pH of 6.7 A lock solution (commercial product A) and a heparin lock solution (commercial product B) having a pH of 6.0 were prepared (comparative example). All of these osmotic pressure ratios were 1.0.
- the catheter lock solutions of the examples and comparative examples assuming that the catheter lock solution touches blood in the catheter, 2 vol% human blood is added to the catheter lock solution, and the pH is measured. The pH buffer capacity of the lock solution was measured.
- Staphylococcus is added to the catheter lock solution to which human blood is added. aureus, strain number IFO 13276) and static culture at 37 ° C. for 24 hours.
- the results are shown in Table 1.
- the pH of the catheter lock solution of the comparative example was 5.3, 6.7, 6.0, but when 2% by volume of blood is added, the pH rises above 7 and is suitable for bacterial growth. As a result, S. aureus grew more than 700 times in 24 hours.
- the catheter lock solution containing the buffer of the example had a small change in pH after the addition of blood, and no growth of S. aureus was observed. From the above results, the known catheter lock solution is neutralized upon contact with blood, causing bacterial growth, and an appropriate buffer is added to the catheter lock solution to maintain a pH of less than 6.0. It was found to show bacteriostatic action.
- Example 2 A catheter lock solution with a pH of 3 to 5 containing buffer at concentrations of 50, 100 and 150 mM and adjusting the osmotic pressure with sodium chloride was prepared (Examples). For comparison, a physiological saline solution having a pH of 3 to 5 was prepared as a catheter lock solution containing no buffer (Comparative Example 1). Further, a glycine-buffer solution was prepared as an example of a buffer that is difficult to maintain in the pH range of 3 to 6 (Comparative Example 2). The pH of all test solutions was adjusted with hydrochloric acid or sodium hydroxide. The buffering ability of the catheter lock solutions of the examples and comparative examples was tested. Assuming that the catheter lock solution touched the blood in the catheter, the change in pH due to the addition of 2% blood was examined.
- Example 4 The effect of pH and buffer on the anticoagulant activity of heparin was tested.
- the titer of heparin decreased with time at pH 2.0 or lower, the decrease in titer was slight at pH 2.5 or higher, and sufficient drug efficacy was shown (Table 4). From this result, it was found that the weak acidification of the catheter lock solution and the addition of a buffering agent do not affect the anticoagulant action of heparin, and the medicinal effect of preventing thrombus in the intravascular catheter is maintained.
- the pH in the comparative examples and examples was measured using TOA AUTO TITRATION (manufactured by Toa DKK Corporation) and pH METER D-21 (manufactured by Horiba, Ltd.) as pH meters.
- Osmostat OM-6040 manufactured by Arkray was used as an osmotic pressure measuring device.
- the strength of heparin was determined by using test team heparin S (Daiichi Kagaku) and quantifying the strength of the anticoagulant action.

カテーテルロック溶液のpHとpH緩衝能、細菌の増殖性について試験を行った。
100mMのリン酸ナトリウム緩衝剤を含み、塩化ナトリウムで浸透圧比を1.0に調整した10単位/mLのヘパリンカテーテルロック溶液を調製した。この溶液は、リン酸ナトリウム緩衝剤の調整により、6.0、5.0、4.0、3.0、2.0の5種類のpHのものを作製した。公知のカテーテルロック溶液として、血液添加前のpHが5.3の0.9%塩化ナトリウム溶液(生理食塩液)、2種類の10単位/mLのヘパリンロック溶液、すなわちpHが6.7のヘパリンロック溶液(市販品A)およびpHが6.0のヘパリンロック溶液(市販品B)を準備した(比較例)。これらの浸透圧比はいずれも1.0であった。
前記実施例および比較例のカテーテルロック溶液について、カテーテルロック溶液がカテーテル内で血液に触れた場合を想定して、このカテーテルロック溶液に2容量%のヒト血液を添加してpHを測定し、カテーテルロック溶液のpH緩衝能を測定した。更にヒト血液を添加したカテーテルロック溶液に、黄色ブドウ球菌(Staphylococcus
aureus, 菌株番号IFO 13276)を接種して、37℃で24時間の静置培養を行った。その結果を表1に示す。比較例のカテーテルロック溶液のpHは5.3、6.7、6.0であったが、2容量%の血液を加えると、いずれもpHが7を超えて上昇し、細菌の増殖に適した環境となったため、黄色ブドウ球菌は、24時間で700倍以上に増殖した。これに対して、実施例の緩衝剤を含むカテーテルロック溶液は、血液添加後のpHの変化が小さく、黄色ブドウ球菌の増殖を認めなかった。以上の結果から、公知のカテーテルロック溶液は血液に接触すると中性化して、細菌の増殖が起こる事、更にカテーテルロック溶液に適切な緩衝剤を添加して、6.0未満のpHを保てば、静菌作用を示す事が判った。
50、100、150mMの濃度で緩衝剤を含み、塩化ナトリウムで浸透圧を調整したpH3~5のカテーテルロック溶液を調製した(実施例)。また、比較のため、緩衝剤を含まないカテーテルロック溶液として、pH3~5の生理食塩液を調製した(比較例1)。さらに、pH3~6の範囲の維持が困難な緩衝剤の例として、グリシン-緩衝液を調製した(比較例2)。全ての試験液のpHは塩酸または水酸化ナトリウムで調整した。前記実施例と比較例のカテーテルロック溶液の緩衝能力について試験を行った。カテーテルロック溶液がカテーテル内で血液に触れた場合を想定して、2%の血液添加によるpHの変化を検討した。
ヘパリンの抗凝固活性に対するpHと緩衝剤の影響について試験した。
100mMのリン酸塩でpH2~7に調整した浸透圧比1.0のヘパリン生食(10単位/mL)について、室温で4週間の保存を行い、ヘパリンの力価を測定した。その結果、pH2.0以下では経時的にヘパリンの力価が低下したが、pH2.5以上では力価の低下は軽微であり、十分な薬効を示した(表4)。この結果から、カテーテルロック溶液の弱酸性化や緩衝剤の添加は、ヘパリンの抗凝血作用に影響を与えず、血管内留置カテーテル内の血栓を防止する薬効が維持される事が分かった。
