Cyanoacrylate tissue adhesives
A tissue adhesive including cyanoacrylate and polyethylene glycol (PEG), wherein the PEG remains a polyether and wherein the tissue adhesive is bioabsorbable. A tissue adhesive including cyanoacrylate bulk monomer and cyanoacrylate nanoparticles containing a therapeutic therein. A kit for applying a tissue adhesive, including the tissue adhesive described above and an applicator. Methods of accelerating degradation of a cyanoacrylate tissue adhesive applying a tissue adhesive, closing an internal wound, administering a therapeutic to tissue, treating cancer, and preventing infection in a wound. Methods of method of making a bioabsorbable tissue adhesive and making a therapeutic tissue adhesive.
1. A tissue adhesive composition, comprising an adhesive comprising 85 v % of a cyanoacrylate monomer selected from the group consisting of methoxyisopropylcyanoacrylate and a combination of octylcyanoacrylate and methoxyisopropylcyanoacrylate in a 50:50 v % ratio, and 15 v % of polyethylene glycol (PEG) that remains a polyether in the adhesive, and polymerized cyanoacrylate nanoparticles containing an effective amount of a therapeutic agent, wherein said nanoparticles are homogenously mixed together and miscible with the adhesive, and when mixed together with the adhesive, remain miscible in the adhesive and do not initiate polymerization of the cyanoacrylate monomer.
2. The tissue adhesive composition of claim 1 , wherein said therapeutic agent is chosen from the group consisting of antibacterial agents, antifungal agents, anticancer agents, and anti-inflammatory drugs.
3. The tissue adhesive composition of claim 1 , wherein said therapeutic agent is an antibacterial agent chosen from the group consisting of polymyxin B sulfate, neomycin sulfate, gentamycin sulfate, gramicidin, zinc bacitracin, and hydroxyquinolone.
4. The tissue adhesive composition of claim 1 , wherein said therapeutic agent is an antifungal agent chosen from the group consisting of terbinafine, clotrimazole, ketoconazole, nystatin, and amphotericin B.
5. The tissue adhesive composition of claim 1 , wherein said therapeutic agent is an anticancer agent chosen from the group consisting of 5-fluorouracil, doxorubicin, and paclitaxel.
6. The tissue adhesive composition of claim 1 , wherein said therapeutic agent is an anti-inflammatory agent chosen from the group consisting of ibuprofen, ketoprofen, dexamethasone, and prednisolone.
7. The tissue adhesive composition of claim 1 , wherein said composition is formulated in a patch.
8. The tissue adhesive composition of claim 7 , wherein said composition is formulated in a patch and said therapeutic agent is chosen from the group consisting of nicotine and glucose.
9. A kit, comprising the tissue adhesive composition of claim 1 and an applicator.
10. A method of treating an incision in a tissue, comprising applying an effective amount of the composition of claim 1 to an incision and allowing the composition to cure on the incision.
11. The method of claim 10 , wherein the therapeutic agent is chosen from the group consisting of antibacterial agents, antifungal agents, anticancer agents, and antiinflammatory drugs.
12. The method of claim 10 , wherein the composition is in the form of a patch.
13. The tissue adhesive composition of claim 1 , wherein said polymerized cyanoacrylate nanoparticles comprise polybutylcyanoacylate.
14. The tissue adhesive composition of claim 1 , wherein the composition remains flowable.
