MSRA-2419
A 5-year-old boy is brought to his pediatrician by his parents. They are concerned that he has been experiencing excessive thirst and needing to go to the bathroom to urinate frequently. There is suspicion that this may be a case of diabetes insipidus. Upon investigation, it is found that his symptoms are unresponsive to a desmopressin (ADH analogue).
What is the most suitable medication for managing this child’s condition?
