The patient is admitted for GI bleeding,but the source is not known.Before ordering endoscopy,the provider orders Sandostatin (octreotide)to be given intravenously.The purpose of this medication is to:
A) increase portal pressure and improve liver function.
B) decrease splanchnic blood flow and portal pressure.
C) vasodilate the splanchnic arteriolar bed.
D) increase blood flow in the liver's collateral circulation.

Somatostatin or octreotide is commonly ordered to slow or stop bleeding.Early administration provides for stabilization before endoscopy.These drugs decrease splanchnic blood flow and reduce portal pressure,and have minimal adverse effects.Vasopressin is used to lower (not increase)portal pressure by vasoconstriction of the splanchnic arteriolar bed.Ultimately,it decreases pressure and flow in liver collateral circulation channels to decrease bleeding.However,vasopressin is not a first-line therapy because of its adverse effects.
