The study included a single dose as well as a combination of 3 daily doses (ranging from 0.2 to 20 micrograms/kg) given consecutively. It was determined that single doses did not result in noteworthy production of epithelial cells. Study 970136 (Randomized, double-blind, placebo-controlled, dose-escalation). Intended to determine the safety and tolerability, and pharmacokinetics of a single dose, administered intravenously (ranging from 5–20 micrograms/kg) in 24 healthy volunteers. It was found that systematic exposure was proportional to the administered dose. Extravascular distribution of the drug was noted. Study 970290 (Open-label). Intended to evaluate pharmacokinetic properties intersubject variability of the drug in four, healthy male volunteers. It was determined that a high intersubject variability was not the cause of dosing errors in previous studies. Study 970276 (Dose-escalation). Intended to determine the safety and tolerability, pharmacokinetic and pharmacodynamics properties of the drug versus a placebo in 18 healthy volunteers. The study consisted of daily IV doses in three consecutive days (20 or 40 micrograms/kg). It was determined that subjects that received three daily doses of 40 micrograms/kg demonstrated adequate production of epithelial cells in the buccal mucosa. Predicted elevation in amylase and lipase were also determined. Study 20010192 (Randomized, double-blind, placebo-controlled, dose-escalation). Intended to determine safety and tolerability, pharmacokinetic and pharmacodynamics properties of the drug versus a placebo by utilization of a single IV dose (ranging from 60 to 250 micrograms/kg) in 84 healthy volunteers.
Post-vagotomy diarrhea is a form of diarrhea which occurs in 10% of people after a truncal vagotomy, which can range from severe to debilitating in approximately 2% to 4% of patients. However, the occurrence of post-vagotomy diarrhea is significantly reduced after proximal selective vagotomy, specifically when celiac and hepatic branches of the vagus are retained. Diagnosis
Treatment
Surgical treatment for refractory post-vagotomy diarrhea is rarely needed and at least one year from the occurrence of symptoms should be allotted to ensure all non-surgical treatments have been appropriately explored. Under severe cases, where surgical intervention does become necessary, a 10 cm reverse jejunal interposition is usually the procedure of choice. == References ==
