Publication number: 20160106841Abstract: Liquid and semi-solid pharmaceutical compositions, which can be administered in liquid form or can be used for preparing capsules, are described herein. The composition comprises the salt of one ore more active agents, polyethylene glycol, 0.2-1.0 mole equivalents of a de-ionizing agent per mole of active agent, and water. The pH of the composition is adjusted within the range of 2.5-7.5. The de-ionizing agent causes partial de-ionization (neutralization) of the salt of the active agent resulting in enhanced bioavailability of salts of weakly acidic, basic or amphoteric active agents as well as lesser amounts of polyethylene glycol (PEG) esters.Type: ApplicationFiled: December 22, 2015Publication date: April 21, 2016Inventors: Nachiappan Chidambaram, Aqeel Fatmi

Patent number: 9192582Abstract: Gastric resistant film-forming compositions are described herein. The composition comprises a gastric resistant natural polymer, a film-forming natural polymer, and optionally a gelling agent. Suitable gastric resistant natural polymers include polysaccharides such as pectin and pectin-like polymers. The film-forming composition can be used to prepare soft or hard shell gelatin capsules which can encapsulate a liquid or semi-solid fill material or a solid tablet (Softlet®) comprising an active agent and one or more pharmaceutically acceptable excipients. Alternatively, the composition can be administered as a liquid with an active agent dissolved or dispersed in the composition. The compositions are not only gastric resistant but may also prevent gastric reflux associated with odor causing liquids, such as fish oil or garlic oil, encapsulated in a unit dosage form and esophageal irritation due to the reflux of irritant drugs delivered orally.Type: GrantFiled: October 6, 2014Date of Patent: November 24, 2015Assignee: Banner Life Sciences LLCInventor: Nachiappan Chidambaram

Publication number: 20070098786Abstract: An enteric valproic acid soft gelatin capsule, in which the enteric polymer is a component of the capsule shell rather than a coating, has been developed. The fill material comprises valproic acid or divalproex sodium and, optionally, one or more pharmaceutically acceptable excipients such as corn oil. The capsule shell is prepared from a mass comprising a film-forming polymer, an acid insoluble polymer, an aqueous solvent, and optionally a plasticizer. Suitable film-forming polymers include gelatin. Suitable acid-insoluble polymers include acrylic-acid/methacrylic acid copolymers. The acid-insoluble polymer is present in an amount from about 8% to about 20% by weight of the wet gel mass. The weight ratio of acid-insoluble polymer to film-forming polymer is from about 25% to about 50%. The aqueous solvent is water or an aqueous solution of alkalis such as ammonia or diethylene amine or hydroalcoholic solutions of the same. Suitable plasticizers include glycerin and triethylcitrate.Type: ApplicationFiled: October 11, 2006Publication date: May 3, 2007Inventors: Nachiappan Chidambaram, Aqeel Fatmi
