Catheter locking solution having antimicrobial and anticoagulation properties
The present invention includes a catheter locking solution having both antimicrobial and anticoagulant properties including a local anesthetic and a viscosifying agent. The local anesthetic of the present invention may be an amino amide; an amino ester; an aminoacylanilide; an aminoalkyl benzoate; an amino carbonate; an N-phenylamidine compound; an N-aminoalkyl amid; an aminoketone, or combinations and mixtures thereof. In a particular embodiment of the present invention, the local anesthetic is tetracaine or dibucaine.

3. The catheter locking solution of claim 1 , wherein the local anesthetic further comprises one or more of bupivacaine, ropivacaine, etidocaine, lidocaine, prilocaine, procaine, novocaine, choloroprocaine, propoxycaine, chlorocaine, mepivacaine, xylocaine, benzocaine, chloroprocaine, cyclomethycaine, dimethocaine, popoxycaine, proparacaine, articaine, carticaine, levobupivacaine, piperocaine, trimecaine, hexylcaine, benoxinate, butucaine, diperodon, phenacaine, falicaine, dyclonine, pramoxine, dimethisoquien, and combinations thereof.
4. The catheter locking solution of claim 1 , wherein the local anesthetic is present in an amount of 0.05 mg/mL-100 mg/mL.
5. The catheter locking solution of claim 1 , wherein the local anesthetic is present in an amount of 0.24 mg/mL-28.2 mg/mL.
6. The catheter locking solution of claim 1 , further comprising an additional antimicrobial agent.
7. A pre-filled syringe comprising a syringe containing a locking solution, said locking solution comprising:
a local anesthetic comprising at least one of dibucaine and tetracaine having anticoagulant and antimicrobial activity to reduce microbial growth and coagulation in an implanted catheter.
8. The pre-filled syringe of claim 7 , wherein the local anesthetic comprises one or more of an amino amide, an amino ester, an aminoacylanilide, an aminoalkyl benzoate, an amino carbonate, an N-phenylamidine compound, an N-aminoalkyl amid, an aminoketone, and combinations thereof.
9. The pre-filled syringe of claim 7 , wherein the local anesthetic further comprises one or more of bupivacaine, ropivacaine, etidocaine, lidocaine, prilocaine, procaine, novocaine, choloroprocaine, propoxycaine, chlorocaine, mepivacaine, xylocaine, benzocaine, chloroprocaine, cyclomethycaine, dimethocaine, popoxycaine, proparacaine, articaine, carticaine, levobupivacaine, piperocaine, trimecaine, hexylcaine, benoxinate, butucaine, diperodon, phenacaine, falicaine, dyclonine, pramoxine, dimethisoquien, and combinations thereof.
10. The pre-filled syringe of claim 7 , wherein the local anesthetic is present in an amount of 0.05 mg/mL-100 mg/mL.
11. The pre-filled syringe of claim 7 , wherein the local anesthetic is present in an amount of 0.24 mg/mL-28.2 mg/mL.
12. The pre-filled syringe of claim 7 , further comprising an additional antimicrobial agent.
13. A catheter comprising a tube defining a lumen therethrough, wherein at least a portion of the lumen is infused with a catheter locking solution, said catheter locking solution comprising:
a local anesthetic comprising at least one of dibucaine and tetracaine having anticoagulant and antimicrobial activity to reduce microbial growth and coagulation in the catheter.
14. The catheter of claim 13 , wherein the local anesthetic comprises one or more of an amino amide, an amino ester, an aminoacylanilide, an aminoalkyl benzoate, an amino carbonate, an N-phenylamidine compound, an N-aminoalkyl amid, an aminoketone, and combinations thereof.
15. The catheter of claim 13 , wherein the local anesthetic further comprises one or more of bupivacaine, ropivacaine, etidocaine, lidocaine, prilocaine, procaine, novocaine, choloroprocaine, propoxycaine, chlorocaine, mepivacaine, xylocaine, benzocaine, chloroprocaine, cyclomethycaine, dimethocaine, popoxycaine, proparacaine, articaine, carticaine, levobupivacaine, piperocaine, trimecaine, hexylcaine, benoxinate, butucaine, diperodon, phenacaine, falicaine, dyclonine, pramoxine, dimethisoquien, and combinations thereof.
