About Desmopressin
Desmopressin is a synthetic analog of antidiuretic hormone (vasopressin), an artificial peptide consisting of 8 amino acids. The drug has a strong antidiuretic action that concentrates the urine and decreases urine output.

About Primary nocturnal euresis / bedwetting
Primary Nocturnal Enuresis / bedwetting is caused in association with miscellaneous factors including abnormal amount of urine produced at night, bladder capacity and sleeping patterns. Children over the age of 5-6 who have not become dry at night and continue to wet the bed at least several times a month are considered to suffer from Primary Nocturnal Euresis. It is said that 10% of 6-year olds, 5% of 10-year olds, and 2% of 16 year olds children are suffering from the disease.

About Central diabetes insipidus
Central Diabetes Insipidus (CDI) is caused by a lack or decrease in secretion of postpituitary antidiuretic hormone, and is characterized. The main symptoms are excessive urine production, excessive thirst and excessive water intake. CDI is classified into three categories according to its cause: 1) secondary by brain tumor, damage to hypothalamus or pituitary, 2) idiopathic and caused for unidentified factors, 3) hereditary and familial. According to the national survey conducted by MHL in 1999 shows the number of CDI patients as approximately 4,700.
