Secretin Synthetic Human side effects
6.1 Clinical Trials Experience Because clinical trials are conducted under varying conditions, adverse reaction rates observed during the clinical trials of a drug cannot always be directly compared to the rates observed during the clinical trials of another drug and may not reflect the adverse reaction rates observed in practice. The data described below reflect exposure to ChiRhoStim® in 531 patients from an open-label clinical trial. The population consisted of patients aged 1 to 91 years, 185 males, 346 females, 480 Caucasians, 31 Blacks, 12 American Indians, 6 Hispanics, and 2 Asians with known or suspected diseases of the exocrine pancreas including chronic pancreatitis and pancreatic cancer. Most patients received a single dose of ChiRhoStim® in a dose range of 0.2 mcg/kg to 0.4 mcg/kg. The most common adverse reactions (reported in at least 2 patients in the trial) are listed in Table 2. TABLE 2 Adverse Reactions in at Least 2 Patients Treated with a Single-Dose of ChiRhoStim® in a Clinical Trial Adverse Reaction ChiRhoStim® Number of Patients N = 531 Nausea 9 Vomiting 3 Flushing 2 Upset stomach 2 Most common adverse reactions (≥2 patients) are nausea, vomiting, flushing, and upset stomach.

Secretin Synthetic Human drug interactions
7.1 Hyporesponse with Anticholinergics The concomitant use anticholinergic drugs may cause a hyporesponse to stimulation testing with ChiRhoStim ® . Discontinue anticholinergic drugs at least 5 half-lives before administering ChiRhoStim ® [see Dosage and Administration (2.1)] . 7.2 Hyperresponse of Gastrin Secretion with H 2 -Receptor Antagonists and PPIs The concomitant use of H 2 -receptor antagonists or PPIs may cause a hyperresponse in gastrin secretion in response to stimulation testing with ChiRhoStim ® , falsely suggesting gastrinoma. Discontinue H 2 -receptor antagonists at least 2 days before administering ChiRhoStim ® to aid in the diagnosis of gastrinoma. The time it takes for serum gastrin concentrations to return to baseline following discontinuation of PPIs is specific to the individual drug. Consult the prescribing information of each specific PPI before administering ChiRhoStim ® to aid in the diagnosis of gastrinoma.
