Method of treating inflammation
The present invention concerns methods of administering a therapeutically effective dose of a sorbent for an inflammatory mediator to a patient where the inflammatory mediator is one or more of enzymes, cytokines, prostaglandins, eicosanoids, leukotrienes, kinins, complement, coagulation factors, endotoxins, enterotoxins, lipopolysaccharide, cell fragments, bile salts, fatty acids, phospholipids, interferon and immunomodulatory antibodies, biologics or drugs.
1. A method of treating inflammation in a patient comprising administering a therapeutically effective dose of a sorbent for an inflammatory mediator to said patient; wherein the sorbent is a biocompatible polymer;
the biocompatible polymer comprising residues from one or more monomers selected from divinylbenzene, ethylvinylbezene, styrene, ethylstyrene, and mixtures thereof,
the biocompatible polymer having a pore structure such that the total pore volume of pore size in the range of 50 {acute over (Å)} to 3000 {acute over (Å)} is greater than 0.5 cc/g to 3.0 cc/g dry polymer; the sorbent being administered orally, via a feeding tube, peritoneally, or rectally;
wherein said inflammatory mediator is a cytokine resulting from inflammatory bowel disease in said patient, burns to said patient, sepsis in said patient, or exposure of said patient to neurotoxins.
2. The method of claim 1 , wherein said inflammatory mediator is present in physiological fluid or a carrier fluid in the patient.
3. The method of claim 2 , wherein said physiological fluids is nasopharyngeal, oral, esophageal, gastric, pancreatic, hepatic, pleural, pericardial, peritoneal, intestinal, prostatic, seminal, vaginal secretions, tears, saliva, mucus, bile, blood, lymph, plasma, serum, synovial fluid, cerebrospinal fluid, urine, and interstitial, intracellular, or extracellular fluid.
4. The method of claim 1 , wherein said biocompatible polymer is supplied as a slurry, or suspension, or dry powder or other dry particulate capable of being wetted.
5. The method of claim 1 , wherein said sorbent is supplied as a slurry or suspension packaged in either single dose or multidose packages for oral administration.
6. The method of claim 1 , wherein said sorbent is supplied as a slurry or suspension packaged in either single dose or multidose packages for administration by enema or feeding tube or any combination therein.
7. The method of claim 1 , wherein said biocompatible polymer is supplied as a dry powder or other dry particulate capable of being wetted externally or internally in the alimentary canal, with or without the addition of wetting agents.
8. The method of claim 6 , wherein said biocompatible polymer is supplied as tablet, dry powder, other dry particulate, capsule or suppository packaged in bottles or blister packs for administration.
9. The method of claim 1 , wherein said biocompatible polymer materials is not metabolizable by human and animal.
10. The method of claim 1 , wherein said biocompatible polymer comprises particles having a diameter in the range for 0.1 micron meters to 2 centimeters.
11. The method of claim 10 , wherein said biocompatible polymer is in the form of powder, beads or other regular or irregularly shaped particulate.
12. The method of claim 1 , wherein said biocompatible polymer is a coated polymer comprising at least one crosslinking agent and at least one dispersing agent;
said dispersing agents selected from the group consisting of hydroxyethyl cellulose, hydroxypopyl cellulose, poly(hydroxyethyl methacrylate), poly(hydroxyethyl acrylate), poly(hydroxypropyl methacrylate), poly(hydroxypropyl acrylate), poly(dimethylaminoethyl methacrylate), poly(dimethylaminoethyl acrylate), poly(diethylamimoethyl methacrylate), poly(diethylaminoethyl acrylate), poly(vinyl alcohol), poly(N-vinylpyrrolidinone), salts of poly(methacrylic acid), and salts of poly(acrylic acid) and mixtures thereof;
said crosslinking agent selected from the group consisting of divinylbenzene, triviny1benzene, divinylnaphthalene, trivinylcyclohexane, divinylsulfone, trimethylolpropane trimethacrylate, trimethylolpropane dimethacrylate, trimethylolpropane triacrylate, trimethylolpropane diacrylate, pentaerythrital dimethacrylates, pentaerythrital trimethacrylates, pentaerythrital, tetramethacrylates, pentaerythritol diacrylates, pentaerythritol triiacrylates, pentaerythritol tetraacrylates, dipentaerythritol dimethacrylates, dipentaerythritol trimethacrylates, dipentaerythritol tetramethacrylates, dipentaerythritol diacrylates, dipentaerythritol triacrylates, dipentaerythritol tetraacrylates, divinylformamide and mixtures thereof;
said polymer being developed simultaneously with the formation of the coating, wherein said dispersing agent is chemically bound to said surface of said biocompatible polymer.
13. The method of claim 1 , wherein said biocompatible polymer is modified with an antibody or ligand.
14. The method of claim 1 , wherein said biocompatible polymer is a porous highly crosslinked styrene or divinylbenzene copolymer.
15. A pharmaceutical kit comprising a therapeutically effective dose of a sorbent for an inflammatory mediator to a patient; wherein the sorbent is a biocompatible polymer;
the biocompatible polymer comprising residues from one or more monomers selected from divinylbenzene, ethylvinylbezene, styrene, ethylstyrene, and mixtures thereof,
the biocompatible polymer having a pore structure such that the total pore volume of pore size in the range of 50 {acute over (Å)} to 3000 {acute over (Å)} is greater than 0.5 cc/g to 3.0 cc/g dry polymer; the sorbent being administered orally, via a feeding tube, peritoneally, or rectally;
wherein said inflammatory mediator is a cytokine resulting from inflammatory bowel disease in said patient, burns to said patient, sepsis in said patient, or exposure of said patient to neurotoxins.
16. The pharmaceutical kit of claim 15 , wherein said biocompatible polymer is supplied as a dry powder or other dry particulate capable of being wetted externally or internally in the alimentary canal, with or without the addition of wetting agents.
17. The pharmaceutical kit of claim 15 , wherein said biocompatible polymer is supplied as tablet, dry powder, other dry particulate, capsule or suppository packaged in bottles or blister packs for administration.
