Side Effects
ADVERSE REACTIONS 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.
Interactions
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.
Warnings
WARNINGS AND PRECAUTIONS Patients with alcoholic or other liver disease may be hyperresponsive to stimulation with ChiRhoStim®, masking the presence of coexisting pancreatic disease. Consider additional testing and clinical assessments for aid in diagnosis. Hyporesponse to Secretin Stimulation Testing in Patients with Vagotomy, Inflammatory Bowel Disease or Receiving Anticholinergics : Discontinue anticholinergic drugs at least 5 half-lives prior to stimulation testing; consider additional testing and clinical assessments for aid in diagnosis. (2.1, 5.1, 7.1) Hyperresponse to Secretin Stimulation Testing : Increased gastrin secretion in patients receiving H 2 -receptor antagonists or PPIs falsely suggesting gastrinoma; discontinue co-administered drug prior to stimulation testing. CONTRAINDICATIONS None. None (4)
