Octreotide is an effective therapeutic option in controlling secretory
diarrhea of varied etiology. However, marked patient-to-patient diffe
rences in the antidiarrheal effects necessitate titration of octreotid
e dose in individual patients to achieve optimal symptom control. A co
nsensus development panel established guidelines for octreotide dose t
itration in patients with secretory diarrhea. Overall, the panel recom
mended an aggressive approach in selecting the initial octreotide dose
and in making subsequent dose escalations in patients with secretory
diarrhea due to gastrointestinal tumors (eg, carcinoids, VIPomas), AID
S, dumping syndrome, short bowel syndrome, radiotherapy, or chemothera
py. To avoid hypoglycemia in patients with diabetes mellitus-associate
d secretory diarrhea, the panel recommended a low initial octreotide d
ose and a conservative titration regimen with close monitoring of bloo
d glucose levels. The end point of therapy should focus on a reduction
in diarrhea (frequency of bowel movements or stool volume) rather tha
n normalization of hormonal profile. Overall, octreotide is well toler
ated; principal side effects are transient injection site pain and gas
trointestinal discomfort. For many patients with secretory diarrhea, o
ctreotide therapy is expected to improve the overall health and qualit
y of life and in the long run will lessen health care costs.
