Which agent is correctly matched with its indicated clinical use?

Desmopressin is a synthetic analog of vasopressin (antidiuretic hormone) and is primarily used to treat diabetes insipidus, a condition characterized by excessive urination and thirst due to the body’s inability to concentrate urine. Desmopressin works by promoting water reabsorption in the kidneys, which reduces urine volume and helps manage the symptoms of diabetes insipidus.

Desmopressin’s mechanism and clinical application are well-established, making it an appropriate choice for this condition. In contrast, the other agents listed do not have the clinical uses stated in the question. For instance, goserelin is mainly utilized for hormone-sensitive conditions like prostate cancer and endometriosis, rather than for growth hormone deficiency. Human chorionic gonadotropin (hCG) is largely used in fertility treatments and to stimulate ovulation, but not for managing bleeding esophageal varices. Lastly, octreotide is effective in managing acromegaly and certain types of tumors, but it is not indicated for infertility treatment. Understanding the specific uses of different agents is crucial in pharmacology, as it ensures appropriate patient care and effective treatment strategies.
