XPHOZAH (tenapanor) 30 mg BID is indicated to reduce serum phosphorus
in adults with chronic kidney disease (CKD) on dialysis as add-on therapy
in patients who have an inadequate response to phosphate binders or who
are intolerant of any dose of phosphate binder therapy.
XPHOZAH is contraindicated in:
- Pediatric patients under 6 years of age
- Patients with known or suspected mechanical gastrointestinal obstruction
Diarrhea
Patients may experience severe diarrhea. Treatment with XPHOZAH should be discontinued in patients who develop severe diarrhea.
Diarrhea, which occurred in 43-53% of patients,
was the only adverse reaction reported in at least 5%
of XPHOZAH-treated patients with CKD on dialysis across
trials. The majority of diarrhea events in XPHOZAH-treated
patients were reported to be mild-to-moderate in severity and
resolved over time, or with dose reduction. Diarrhea was typically
reported soon after initiation but could occur at any time during
treatment with XPHOZAH. Severe diarrhea was reported in 5% of
XPHOZAH-treated patients in these trials.
