Definitions

• the present invention discloses water soluble dosage forms comprising ibandronate and/or any pharmaceutically suitable derivative thereof which are developed to be used in prevention and treatment of bone loss and diseases associated with bone loss.
• Bone loss or in other words "osteoporosis” is defined as a disease characterized by low bone mass and susceptibility to bone fragility as a result of distortion in microstructure of bone tissue and increased risk in bone fracture. The disease does not generally result in death; however, it appears as a major health problem affecting quality of life in the world.
• Bisphosphonates are pharmaceutical agents which are commonly used in prevention and treatment of bone loss and diseases associated with bone loss. The studies conducted have shown that starting bisphosphonate treatment reduces risk of bone fracture when there appears osteoporosis or nontraumatic bone fracture in postmenopausal period (Fink HA the Fracture Intervention Trial (FIT) 2003).
• Ibandronate which is a bisphosphonate having the chemical name of l-hydroxy-3-N-methyl- N-pentyl aminopropy 1-1.1- diphosphonic acid was firstly disclosed in the patent numbered DE3623397. It is known that ibandronate is used in treatment of bone diseases, calcium metabolism disorders, osteoporosis, tumor osteolysis or Paget' s disease. Ibandronate should be administered frequently, intermittently and for a long period of time in treatment of said diseases; therefore, the aim of ibandronate administration should be oral administration which is much more accepted by lots of patients in addition to intravenous administration.
