4. Uses of Octreotide acetate
Octreotide acetate (CAS NO.83150-76-9) has been used off-label for the treatment of severe, refractory diarrhea from other causes. It has also been used with varying degrees of success in infants with nesidioblastosis to help decrease insulin hypersecretion. Octreotide may be useful in the treatment of thymic neoplasms. It has been used in the treatment of malignant bowel obstruction. Octreotide may be used in conjunction with midodrine to partially reverse peripheral vasodilation in the hepato-renal syndrome.
