Patent number: 11185588Abstract: The invention provides novel solid pharmaceutical dosage forms for oral administration, after being constituted in water. The solid dosage forms comprise a therapeutically effective amount of valganciclovir hydrochloride and a non-hygroscopic organic acid present in an amount sufficient to stabilize the valganciclovir hydrochloride in a predetermined amount of water. The present invention also provides novel liquid pharmaceutical dosage forms for oral administration after constituting the solid pharmaceutical dosage form with water. A non-hygroscopic bulking agent may optionally be included in the above dosage form. These novel pharmaceutical dosage forms are useful in the treatment or control of viruses such as herpes simplex virus and cytomegalovirus. The present invention also provides a method for treating these diseases employing the solid and liquid pharmaceutical dosage forms and a method for preparing these pharmaceutical dosage forms.Type: GrantFiled: December 19, 2018Date of Patent: November 30, 2021Assignee: Hoffmann-La Roche Inc.Inventors: Maria Oksana Bachynsky, Martin Howard Infeld, Navnit Hargovindas Shah

Patent number: 9370492Abstract: The present invention provides novel solid pharmaceutical dosage forms for oral administration comprising a bisphosphonate, or a pharmaceutically acceptable salt thereof, which bisphosphonate is present in an amount not therapeutically effective when the bisphosphonate is orally administered alone, and a modified amino acid carrier, or a pharmaceutically acceptable salt thereof, which modified amino acid carrier is present in an amount effective to facilitate absorption of the bisphosphonate in the gastrointestinal tract such that the bisphosphonate is therapeutically effective. The ratio of bisphosphonate to modified amino acid carrier is from about 1:30 to about 1:1, respectively. These novel solid pharmaceutical dosage forms are useful in the treatment or control of bone diseases and particular disorders in calcium metabolism, including, for example, osteoporosis, hypercalcaemia of cancer, and the treatment of metastatic bone pain.Type: GrantFiled: July 16, 2009Date of Patent: June 21, 2016Assignee: EMISPHERE TECHNOLOGIES, INC.Inventors: Hashim Ahmed, Lewis Bender, Martin Howard Infeld, Shingai Majuru, Wantanee Phuapradit, Navnit Hargovindas Shah, Zhongshui Yu
