20150132380 | A DELAYED RELEASE DRUG FORMULATION - Delayed release of a drug to the colon is achieved from a delayed release formulation comprising a core and a coating for the core. The core comprises a drug and the coating comprises an outer layer and at least one layer between the core and the outer layer selected from the group consisting of an isolation layer and an inner layer. The outer layer comprises a mixture of a first polymeric material which is susceptible to attack by colonic bacteria, and a second polymeric material which has a pH threshold at about pH 5 or above. The inner layer comprises a third polymeric material which is soluble in intestinal fluid or gastrointestinal fluid, said third polymeric material being selected from an at least partially neutralised polycarboxylic acid and a non-ionic polymer. In embodiments in which the third polymeric material is a non-ionic polymer, the inner layer comprises at least one of a buffer agent and a base. The isolation layer comprises a non-ionic polymer which is soluble in intestinal fluid or gastrointestinal fluid. The outer is applied directly to the inner layer or the isolation layer using a coating preparation formed by combining the first polymeric material in an aqueous medium with a second polymeric material in an organic medium. Advantages of formulations according to the present invention include accelerated release of the drug when exposed to colonic conditions and reduction or elimination of a food and/or alcohol effect on drug release after administration. | 05-14-2015 |

20140056980 | DELAYED RELEASE DRUG FORMULATION - In a delayed release formulation comprising a core containing a drug and a delayed release coating for providing intestinal release, release of the drug in the colon is accelerated by including an isolation layer between the core and the delayed release coating. The delayed release coating comprises an inner layer and an outer layer. The outer layer comprises a pH dependently soluble polymeric material which has a pH threshold at about pH 5 or above. The inner layer comprises a soluble polymeric material which is soluble in intestinal fluid or gastrointestinal fluid, said soluble polymeric material being selected from the group consisting of a polycarboxylic acid polymer that is at least partially neutralised, and a non-ionic polymer, provided that, where said soluble polymeric material is a non-ionic polymer, said inner layer comprises at least one additive selected from a buffer agent and a base. | 02-27-2014 |
20090018125 | Pharmaceutical Composition and Its Use - Polyunsaturated fatty acid (“PUFA”) or a pharmacologically acceptable salt or derivative thereof (such as EPA and/or DHA) is used in combination with at least one of an immunosuppressive agent or an antineoplastic agent, said agent(s) having at least one amino acid residue, or a pharmacologically acceptable salt or derivative thereof (such as methotrexate or cyclosporin) in the treatment of conditions involving acutely or chronically inadequate immune response. Specific conditions that may be treated include chronic inflammatory diseases (e.g. Crohn's disease and ulcerative colitis) and tumour diseases (e.g. bowel cancer and prostate cancer). One advantage of preferred embodiments of the invention is that bioavailability of immunosuppressive or antineoplastic agents is increased. | 01-15-2009 |
