Patent number: 11534406Abstract: 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.Type: GrantFiled: March 18, 2020Date of Patent: December 27, 2022Assignee: Tillotts Pharma AGInventors: Felipe José Oliveira Varum, Roberto Carlos Bravo González, Thomas Buser, Abdul Waseh Basit, Ana Cristina Freire

Publication number: 20220023222Abstract: A method produces a coatable core for a delayed release drug formulation for oral administration, to deliver a drug to the colon. The method involves forming a core containing a drug. An outer layer coating preparation is formed by combining a first aqueous preparation of an enzymatically degradable polymer, which is degradable by colonic bacterial enzymes; a second aqueous preparation of a film-forming enteric polymer having a pH threshold of about pH 6 or above; and an organic anti-tack agent. The core is then coated with the outer layer coating preparation to form an outer layer coated core.Type: ApplicationFiled: December 5, 2019Publication date: January 27, 2022Applicant: Tillotts Pharma AGInventors: Felipe Varum, Laetitia Von Rochow, Carsten Markus Füller, Roberto Carlos Bravo González

Publication number: 20220016038Abstract: A delayed release drug formulation for oral administration delivers a drug to the colon of a subject. The formulation includes a core containing a drug and a coating for the core. The coating contains an outer layer and an inner layer. The outer layer contains a film-forming enteric polymer having a pH threshold at about pH 6 or above, and the inner layer contains a film-forming non-ionic polymer that is soluble in intestinal or gastrointestinal fluid and a buffer agent in an amount from more than 20 wt % to about 60 wt % based on the dry weight of the non-ionic polymer.Type: ApplicationFiled: December 5, 2019Publication date: January 20, 2022Applicant: Tillotts Pharma AGInventors: Felipe Varum, Roberto Carlos Bravo González

Publication number: 20220016040Abstract: A method produces a coatable core for a modified release drug formulation for oral administration. The coatable core has a high drug load of at least 70 wt % based on the total weight of the coatable core. The method involves the steps of granulating a composition containing a drug and at least one binder to form granules; blending the granules with a pharmacologically acceptable disintegrant and optionally, one or more additional pharmacologically acceptable excipients, to form a compression blend, wherein the disintegrant is present in an amount from about 0.5 wt % to about 5 wt %, based on the total weight of the coatable core; and compressing the compression blend using an external lubrication compression method to form a coatable core.Type: ApplicationFiled: December 5, 2019Publication date: January 20, 2022Applicant: Tillotts Pharma AGInventors: Thomas BUSER, Yalcin Cetinkaya-Coskun, Roberto Carlos Bravo González

Publication number: 20220016037Abstract: A delayed release drug formulation contains a core containing a drug and a delayed release coating for intestinal release, where release of the drug in the colon is not hindered by the absence of an alkaline middle layer between the core and the outer layer. The delayed release coating contains an outer coating, and optionally, an isolation layer. The outer coating contains a mixture of an enzymatically degradable polysaccharide which is degradable by colonic enzymes selected from the group of starch, amylose, amylopectin, chitosan, chondroitin sulfate, cyclodextrin, dextran, ptallulan, carrageenan, scleroglucan, curdulan, and levan and a film-forming enteric polymer having a pH threshold at about pH 6 or above. The enzymatically degradable polysaccharide and the enteric polymer are present in the outer coating in a ratio of more than 60:40.Type: ApplicationFiled: December 5, 2019Publication date: January 20, 2022Applicant: Tillotts Pharma AGInventors: Felipe Varum, Roberto Carlos Bravo González
