Used for Hyperphosphatemia
Used for Hyperphosphatemia

Xphozah (tenapanor) is a prescription medication that's used to lower blood phosphate levels in adults with chronic kidney disease (CKD) on dialysis. It's the first and only FDA-approved phosphate absorption inhibitor of its kind; it prevents your gut from absorbing phosphate into your blood. Xphozah (tenapanor) is a tablet that's taken by mouth twice a day, before breakfast and dinner. A common side effect is diarrhea, but it usually goes away as you continue treatment.

What is Xphozah (tenapanor)?

What is Xphozah (tenapanor) used for?

  • Add-on treatment for lowering blood phosphorus levels in adults with chronic kidney disease (CKD) on dialysis who haven't responded well to or can't take phosphate binders

How Xphozah (tenapanor) works

Xphozah (tenapanor) is a sodium/hydrogen exchanger 3 (NHE3) inhibitor. It works by blocking NHE3, which is a protein in your gut that regulates the amount of fluids and electrolytes (like phosphorous) in your body.

By blocking NHE3, the medication prevents some of the phosphorus from food from being absorbed into your body. This helps lower your blood phosphate levels, which is important for protecting your kidneys and bones from damage due to phosphate buildup in CKD.

Pharmacist tips for Xphozah (tenapanor)

pharmacist

  • Take Xphozah (tenapanor) 5 to 10 minutes before breakfast and dinner. This can help the medication work best for you.

    • Try to take Xphozah (tenapanor) around the same times every day. If you accidentally forgot to take the medication, then skip the missed dose and take the medication at your next regularly scheduled dose.

      • On your dialysis days, take Xphozah (tenapanor) right before the next meal you have after your dialysis session. Xphozah (tenapanor) can commonly cause diarrhea, which can lead to dehydration (low fluids in the body) and low levels of sodium. This is especially dangerous during your dialysis session.

        • Avoid taking Xphozah (tenapanor) within 3 hours of sodium polystyrene sulfonate (SPS), a medication that helps lower blood potassium levels. Sodium polystyrene sulfonate (SPS) might cause Xphozah (tenapanor) to work less well in your body.

          • Don't take Xphozah (tenapanor) with stool softeners or laxatives. Xphozah (tenapanor) can sometimes cause diarrhea, which can worsen with these medications.

            • Let your provider or pharmacist know what medications you're taking or planning to take, including over-the-counter products and supplements. Your providers can check for drug interactions with Xphozah (tenapanor) and make sure all your medications are safe to take together.

              faqs

              Frequently asked questions about Xphozah (tenapanor)

              Does Xphozah (tenapanor) cause diarrhea?
              Yes, Xphozah (tenapanor) can commonly cause diarrhea. In clinical studies, about half of the people who took this medication had diarrhea. Most cases were mild to moderate. Diarrhea typically happens soon after you start treatment, but it should get better as you continue to take Xphozah (tenapanor). Make sure to drink plenty of fluids to stay hydrated. Talk to your provider if you continue to have multiple watery bowel movements per day while you're taking Xphozah (tenapanor). Your provider might lower your dose or discuss with you about other ways to manage this side effect.
              What's the difference between Xphozah (tenapanor) and Renvela?
              Xphozah (tenapanor) and sevelamer carbonate (Renvela) are both medications that lower blood phosphate levels in people with CKD on dialysis, but they work differently. Xphozah (tenapanor) is a phosphate blocker. It works by blocking certain proteins in your gut from absorbing phosphate from food that you ate. On the other hand, sevelamer carbonate (Renvela) is a phosphate binder. It physically attaches to the phosphate from food so your body can't absorb it. In addition, Xphozah (tenapanor) is taken before breakfast and dinner. But sevelamer carbonate (Renvela) is taken with every meal you have so you might have to take it more often than Xphozah (tenapanor). Talk with your provider to see which medication is a better option for you.
              Can you take Xphozah (tenapanor) without food?
              You should take Xphozah (tenapanor) right before your morning and evening meals for the medication to work the best it can. Studies show that Xphozah (tenapanor) can lower your phosphate levels better if you take it 5 to 10 minutes before these meals. The medication works by blocking proteins in your gut from absorbing the phosphate that's in the food you just ate. Xphozah (tenapanor) won't work as well if you take it on an empty stomach because there's no phosphate from food to block.
              How well does Xphozah (tenapanor) work?
              Clinical studies showed that people who took Xphozah (tenapanor) had lower blood phosphate levels than people who took a placebo after 6 months. In addition, Xphozah (tenapanor) might work well if you haven't had improvement with phosphate binders. A 4-week study showed that adding Xphozah (tenapanor) to a phosphate binder dropped blood phosphate levels more than a phosphate binder alone. Your provider will order blood work to check your phosphate levels and see how well the medication is working for you. Discuss with your provider about your lab results and your Xphozah (tenapanor) treatment.
              Can you take Xphozah (tenapanor) without a phosphate binder?
              Depending on your situation, it might be possible for you to take Xphozah (tenapanor) without a phosphate binder. Xphozah (tenapanor) can help lower blood phosphate levels in adults with CKD on dialysis in two different situations. Some people need extra help lowering their phosphate levels even if they're already taking a phosphate binder, so adding Xphozah (tenapanor) to phosphate binder therapy can be beneficial. But for people who can't tolerate phosphate binders, taking Xphozah (tenapanor) alone is an option. Talk to your provider about whether you've already tried other medications to lower your blood phosphate levels. Your provider will help you decide on a treatment plan that works for you.
