About Opioid-induced Constipation

Constipation is one of the most commonly reported side effects
associated with opioid treatment, particularly among patients with
chronic non-cancer pain and patients with cancer pain.5 OIC
is a result of increased fluid absorption and reduced gastro-intestinal
(GI) motility due to mu-opioid receptor binding in the GI tract. OIC is
defined as a change in bowel habits that is characterized by any of the
following after initiating opioid therapy: reduced bowel movement
frequency, development or worsening of straining to pass bowel
movements, a sense of incomplete rectal evacuation, or harder stool
consistency.6 In patients receiving opioid therapy for
chronic non-cancer pain, the prevalence of OIC ranges from approximately
40-60 percent.7

About Rizmoic®

Rizmoic® (naldemedine) is indicated for the treatment of opioid-induced
constipation (OIC) in adult patients who have previously been treated
with a laxative. Rizmoic® is a peripherally acting mu-opioid receptor
antagonist (PAMORA) that has been developed by Shionogi as a once-daily
treatment of OIC. The efficacy and safety of naldemedine have been
evaluated in randomized, double-blinded, placebo-controlled studies in
adult patients with OIC who have chronic non-cancer pain or who have
cancer pain.8-12 Rizmoic® is expected to be a new treatment
option that can improve the quality of life significantly in patients
with OIC in pain management with opioid analgesics.
