Somatostatin against Octreotide
The hormone that switches growth hormone off and the analogue built from it. Native somatostatin lasts minutes, which is why the approved drugs in this family are all modified versions.
Column A
SomatostatinSomatostatin (growth hormone inhibiting hormone)
The natural hormone that switches off growth hormone release; its analogues like octreotide are approved drugs.
Column B
OctreotideOctreotide (somatostatin analogue)
An FDA-approved long-acting somatostatin analogue used for acromegaly and hormone-secreting tumors.
