lokelma vs kayexalate
A confirmed diagnosis of non-life-threatening hyperkalemia ... (Kayexalate, Kionex) … FDA approval. As kidney function deteriorates, the body’s ability to excrete potassium begins to decline, placing those with CKD or end-stage renal disease (ESRD) at a higher risk of hyperkalemia [1, 3, 4]. Kellogg Suite 108 Patiromer is not absorbed by the gut, thus it has no systemic side effects. Acute hyperkalemia is a clinical emergency that requires immediate treatment with the agents discussed below (TABLE 1).IV Calcium: IV calcium is indicated when the serum potassium is >6.5 mEq/L regardless of whether ECG changes are present.6 Given their poor sensitivity and specificity, ECG changes should not be used as diagnostic criteria for treatment of hyperkalemia.7 The immediate goal of acute management in hyperkalemi… Lokelma (loh-KEL-mah, sodium zirconium cyclosilicate) will be a new Rx option to treat high potassium levels, or hyperkalemia.. One issue with this medication is that it also binds magnesium and can result in hypomagnesemia (5.3% of patients), which is not seen with Lokelma. nature.” And according to other sources, you likely eat ~4 mg of zirconium (Terms of Use | Privacy Policy). completely insoluble in aqueous solutions, and therefore, there is no systemic The potassium complex is then excreted in stool. 1,2 † In Study 2, patients with hyperkalemia who achieved normokalemia with LOKELMA in the 48-hour … Management of hyperkalemia with a cation-exchange resin N Engl J Med. What’s the evidence behind it? what it does—it lowers your potassium. Summary Lokelma and Veltassa is used to treat high levels of potassium in blood (hyperkalemia). Another advantage of Patiromer over Kayexalate is that it can be given in heart failure, hypertension, and CKD etc. 1958. In fact, in mice models, there has been 99% How dangerous are ground glass nodules over time? The mean starting potassium level was 5.5 mEq/L with 82% reaching normokalemia within 24 hours with mean reduction 0.72 mEq/L at 24 hours. The approval of Lokelma “addresses a significant unmet need by bringing a rapid and sustained therapeutic option for patients with hyperkalaemia,” she added. Once they achieved normokalemia, they were randomized to receive Lokelma 5-g qd for 12 months without any dietary or medication restrictions. Send. The 10-g group saw K levels decrease on average 0.92 mEq/L after 38 hours of treatment. traps monovalent cations specifically K+ and NH4+ over divalent cations Lokelma contains the active drug sodium zirconium cyclosilicate. Again, this study excluded patients with K>6.5, EKG changes, patients requiring hospitalization, and patients receiving HD. of Emergency Medicine On the Horizon… Study evaluating Lokelma in patients with acutely elevated K>5.8. groups for some time, and was actually used as the primary component of the I’m very curious to see what this next study on Lokelma in acutely elelvated K>5.8 will show. It is used to treat too much potassium in the body. It was a Phase 2 trial that included 90 patients that were randomized to receive Lokelma 0.3 gram (12 pts), 3 gram (24 pts), and 10 grams (24 pts), or placebo (30 pts) tid. It also addresses some other retrospective studies on Kayexalate as well as the only RCT of Kayexalate I can find (linked here “Randomized Clinical Trial of Sodium Polystyrene Sulfonate for the Treatment of Mild Hyperkalemia in CKD 2015), which showed a mean reduction of 1.25 mEq/L at 7 days compared to placebo with reduction 0.21 mEq/L at 7 days (sample size of total 33 patients). Kayexalate hasn’t gotten a lot of love as of late. 1 ‡ In vitro study; based on simulated intestinal fluid. Of the 751 patients, 746 (99%) achieved normokalemia during the first 72 hours. ADVERSE REACTIONS: The most common adverse reaction with LOKELMA was mild to moderate edema. 2015. SPS (Kayexalate). For instance, it has been known that ARB/ACE-I are renal protective and would be the ideal HTN medication in patients with CKD. LOKELMA can cause swelling (edema) caused by fluid retention in your body (such as hands, ankles, feet). From the Surviving Sepsis Guidelines: Criteria for…. Veltassa works similarly to Kayexalate and Lokelma in that it absorbs potassium in the GI tract. One important caveat of these trials is that Lokelma was studied in patients with CKD with mild hyperkalemia, “Randomized Clinical Trial of Sodium Polystyrene Sulfonate for the Treatment of Mild Hyperkalemia in CKD 2015. Some of the dosage forms listed on this page may not apply to the brand name Lokelma.. For the Consumer Harel Z, Harel S, Shah PS, Wald R, Perl J, Bell CM. It seems prior to 2015 when the other resin medications weren’t yet available, there was little interest in further studying Kayexalate as there were no other options. 2. The potassium lowering effects of Lokelma were further evidenced by the maintenance phase that showed a stepwise decline in K levels depending on Lokelma dose. Lokelma is not absorbed into the bloodstream. There is currently a phase 2, multicenter, randomized, double-blind, placebo study underway called “A Study to Evaluate a Potassium Normalization Treatment Regiment Including Sodium Zirconium Cyclosilicate (ZS) among Patients with S-K >5.8 (ENERGIZE)” (Link). In fact, median time to normokalemia was 2.2 hours with 84% achieving normokalemia by 24 hours and 98% by 48 hours. Get our weekly email update, and explore our library of practice updates and review articles. It can also bind certain medications, and therefore, it is recommended that you do not take Veltassa 3 hours before or after taking other oral medications, which seems impossible in the patient population I would want to give this to. The hyperkalemia drug market has been predicted to increase sixfold over coming years to >$2 billion, if drugmakers can successfully convince physicians to maintain patients with kidney disease on renin-angiotensin-aldosterone system inhibitors, and then treat their chronic hyperkalemia with Lokelma or Veltassa. Maybe one day we’ll even see a randomized, controlled, head-to-head trial of all these medications…, Rush University Medical Center Of these patients, 237 patients achieved normokalemia, and were then randomized to the maintenance phase, where they either received Lokelma 5 g (45 pts), 10 g (51 pts), or 15 g (56 pts), or placebo (85 pts) for 28 days. In vitro studies showed medications including amlodipine, ciprofloxacin, levothyroxine, and others were bound >50% to Veltassa. Mostly, though, I’m just excited that there’s some new players entering the resin game of lowering potassium. Does it work? Watch for signs of swelling in your body especially if you limit sodium in your diet or are likely to have fluid retention in your body due to heart or kidney problems. Per Kidney International Journal (who knew this Patiromer (Veltessa). LOKELMA contains 400 mg of sodium in each 5 g dose. In fact, these trials primarily focused on the exciting new idea that Lokelma could be used concomitantly with ARB/ACE-I for treating CKD patients. In Europe, prevalence varies between 3.3% to 17.3% and in China 6.7% to 18.3% [1, 2]. 751 patients with CKD received Lokelma 10 g tid for 24-72 hours. Again, this study showed improved rate of normokalemia in the Lokelma group vs. placebo in days 3-14. The Lokelma 10-g group showed a mean reduction of 0.7 mEq/L vs. a 0.5 mEq/L reduction in both the 5-g and 2.5-g groups. over its generic name, Zirconium cyclosilicate, since it says right in the name Please Note: Only individuals with an active subscription will be able to access the full article. All the best in pulmonary & critical care. Furthermore, Lokelma differs from our friend, Kayexalate, and our other seen potassium lowering agent, Patiromer (Veltassa), in that Lokelma was specifically engineered as a lattice structure that preferentially traps monovalent cations specifically K+ and NH4+ over divalent cations (e.g. Also have quick blurbs about our friend, Kayexalate, as well as a small summary on Veltassa (Patiromer) that you may see used at other institutions. Essentially, all the best drugs were bound by Veltassa. The drug was tested against placebo (not Kayexalate) in the clinical trials that resulted in its approval. Ca2+ or Mg2+). 0. In fact, These patients on average had K 5.3 mEq/L. Current guidelines recommend medical management directed at cardiac stabilization, intracellular shift of serum potassium and potas… by Ashley Lyles, Staff Writer, MedPage Today May 10, 2019 Subject: AstraZeneca’s Lokelma Approved In US With Label Benefits Over Veltassa Add a personalized message to your email. The experimental arm will receive Lokelma 10 mg tid in addition to insulin/dextrose, while the control arm will receive placebo in addition to insulin/dextrose. Safety and efficacy of Lokelma and Veltassa in pediatric patients have not been established (1-2). LOKELMA is a odorless, insoluble white to grey powder for oral suspension. Edema was a common side effect of Lokelma. If you really want to show your age, you The average potassium level at start of study was 5.6 mEq/L with decline to 4.5 mEq/L during the first 48-hour phase. Beta blockers safe for most patients with asthma or COPD? 0. Most patients tolerated the medication without issue. In 2017, the FDA warned against giving Kayexalate within three hours of other drugs, to avoid impaired absorption of medications. Additional research should focus on drug-drug interactions in patients on multiple medications, incidence of rare adverse events, and use in high-risk populations. Ca2+ or … Phone: (312) 942-7802 AstraZeneca bought Lokelma's maker in 2015 but could not ramp up drug production until 2018. The median starting potassium level was 5.7 mEq/L. Lokelma is indicated for the treatment of hyperkalemia in adults. Last updated on Oct 5, 2020. The newest cation exchange resin, sodium zirconium cyclosilicate (Lokelma), was approved in May 2018. The benefit of this study was that it included patients with CKD and ESRD on dialysis, and excluded patients who received other medical therapies to treat their hyperkalemia. However, the main objective of this trial was to observe the real-life compliance of Lokelma as well as to investigate if rates of ARB/ACE-I use increased while on Lokelma. 65% also used ARB/ACE-I with 87% of these patients able to continue or even have their dose increased while on the maintenance dose of Lokelma. Lokelma works by binding to potassium ions in the gut and eliminating them from the body through the stool. With Lokelma, nephrologist could safely give ARB/ACE-I to these CKD patients along with daily Lokelma in long term use. Kayexalate has high sodium content and this can be potentially harmful in case of heart failure, hypertension and even in advanced chronic kidney disease. Cancel. Use the first 3 letters in Lokelma's brand name as a clue to remember its use. It showed that a single-dose Kayexalate of 30-gram had a median decrease of 0.8 mEq/L while a single dose of 15-gram kayexalate had median decrease 0.5 mEq/L within 24-hours of treatment. These studies did not include patients with ESRD or emergency department patients with acute elevations in potassium levels. Other medications like clopidogrel, furosemide, metformin, metoprolol, and warfarin were bound 30-50% to Veltassa. Trial Data Confirm: Veltassa, Lokelma Effective for Hyperkalemia — But agents' long-term safety and efficacy not yet established. The European Union's regulatory agency also approved Lokelma for use in the EU. Tracheostomy in COVID-19: Who, When, How? LOKELMA is a drug for the treatment of hyperkalemia in adults.Hyperkalemia is a condition in which the amount of potassium in the blood is too high. This study is right in the ED realm! existed): “Zirconium is a biologically inert trace element found widely in Dept. recovery of Lokelma in stool of rats treated with Lokelma. AstraZeneca today presented the results from the HARMONIZE Global Phase III trial, which investigated the safety and efficacy of Lokelma (sodium zirconium cyclosilicate) vs. placebo in patients with hyperkalaemia in Japan, Korea, Taiwan and Russia.The results were presented at the American Society of Nephrology (ASN) Kidney Week 2018, San Diego, California, US. Studies assessing the safety and efficacy of Lokelma looked at the following: The FDA approved oral sodium zirconium cyclosilicate (ZS-9), to be marketed as Lokelma, for the treatment of hyperkalemia. KAYEXALATE can be administered either orally or as an enema. of the following criteria are met: 1. 2 § Based on nonclinical and early phase studies. All other readers will be directed to the abstract and would need to subscribe. KAYEXALATE is a cation-exchange resin prepared in the sodium phase, with an in vivo exchange capacity of approximately 1 mmol (in vitro approximately 3.1 mmol) of potassium per gram. However, their use in this CKD population is limited by their hyperkalemia side effect. This paper is definitely worth a read! Veltassa was FDA approved in 2015 before Lokelma (2018) and may see at certain institutions. Chronic kidney disease (CKD) is a condition that affects more than 20 million people in the USA. It reduces potassium by exchanging sodium and hydrogen for potassium in the GI tract. Hyponatremia corrected too quickly and dangerously…, Management of Ground Glass and Subsolid Pulmonary…, Open Critical Care: a great new hub for critical…, Inspiratory collapse of the inferior vena cava: What…, Subsegmental pulmonary embolism: anticoagulation or…, FDA approves new hyperkalemia drug Lokelma, FDA warned against giving Kayexalate within three hours of other drugs, Diffuse Lung Disease & Interstitial Lung Disease. LOKELMA can cause swelling (edema) caused by fluid retention in your body (such as hands, ankles, feet). daily in your normal diet. zirconium has been known to have this unique “absorbing” property by nephrology Since 2015, however, there have been multiple studies on Kayexelate as well as these new trials on Lokelma and Veltassa. ALL. Removal of Kayexalate from the treatment algorithm simplifies matters and allows us to focus on kaliuresis, which can be extremely effective and is often under-utilized. | SODIUM ZIRCONIUM CYCLOSILICATE (SOE dee um zir KOE nee um SYE kloe SIL i kate) takes potassium out of the body by binding to it in the intestines. Am J Med 2013;126(3):264.e9–264.e24. It also has a slower onset of action ~7 hours while onset for Lokelma is ~ 1 hour. Lokelma Side Effects.

First off, Lokelma is the brand name, and way more preferred Monitor serum potassium and adjust the dose of Lokelma and Veltassa based on the serum potassium level and the desired target range. I’m sure everyone has seen our new friend, Lokelma, on the Rush hyperkalemia order set. After achieving normokalemia, these patients were then randomized to receive Lokelma 5g, 10g, or placebo for 14 days. Lokelma contains the active ingredient sodium zirconium cyclosilicate, which lowers the level of potassium in the body and helps to keep it at a normal level. Lastly, Lokelma is also a relatively safe agent as it is Jul 252018 The FDA approved oral sodium zirconium cyclosilicate (ZS-9), to be marketed as Lokelma, for the treatment of hyperkalemia. (e.g. Watch for signs of swelling in your body especially if you limit sodium in your diet or are likely to have fluid retention in your body due to heart or kidney problems. Lokelma was specifically engineered as a lattice structure that preferentially LOKELMA Savings, Coupons and Information. Post was not sent - check your email addresses! The other most common side effect was GI upset including mild diarrhea, nausea, and abdominal cramping. It’s shown it can lower potassium and seems fairly well tolerated by patients even in longterm use. and our other seen potassium lowering agent, Patiromer (Veltassa), in that Think of Lokelma as similar to sodium polystyrene sulfonate (Kayexalate, etc) or Veltassa.They all bring down potassium levels by binding potassium in the gut...and removing it from the body. Patiromer and ZS9 have improved upon the age-old standard SPS for the treatment of hyperkalemia. Stay up-to-date in pulmonary and critical care. But be on the lookout for this! 0. Our faculty are internationally recognized for their teaching accomplishments, scholarship, and dedication to excellent patient care. In addition, ~92% of patients showed normal potassium levels within 48 hours. Of these studied patients, 63% of patients completed the 12-month time period. may see it sometimes referred to as ZS-9 when it was first being studied in the Below are descriptions of the 4 studies including links to the primary source. In placebo-controlled trials up to 28 days, edema was reported in 4.4%, 5.9%, 16.1% of patients treated with 5 g, 10 g and 15 g of LOKELMA once daily, respectively vs 2.4% of … Gastrointestinal adverse events with sodium polystyrene sulfonate (Kayexalate) use: a systematic review. 1961 Jan 19;264:115-9. doi: 10.1056/NEJM196101192640303. sodium polystyrene sulfonate. 7 It has a high affinity for potassium ions, unlike patiromer and SPS, and does not affect serum magnesium or calcium levels. Third time's the charm for AstraZeneca’s blockbuster hopeful Lokelma, formerly known as ZS-9 and also known for its two-in-a-row rejections on manufacturing shortfalls. LOKELMA PROVIDES RAPID* AND SUSTAINED † K + CONTROL FOR YOUR PATIENTS WITH HYPERKALEMIA 1 *In Study 1, LOKELMA 10 g tid demonstrated a greater reduction in serum K + levels vs placebo at 48 hours and started to work as early as 1 hour in patients with hyperkalemia not on dialysis. No spam. The side effects are mainly related to the gut. In contrast, Kayexalate is a nonspecific binding agent SZC (Lokelma). The drug seems to work better than sodium polystyrene sulfonate (Kayexalate), reducing serum potassium levels within an hour and restoring normal levels after about 2 hours in most patients. The Food and Drug Administration (FDA) has approved Lokelma (sodium zirconium cyclosilicate; AstraZeneca) for the treatment of hyperkalemia in adults. Clinical Journal of American Society of Nephrology 2019 (Link). This was the first study of Lokelma in Humans. Acute colonic necrosis associated with sodium polystyrene sulfonate (Kayexalate) enemas in a critically ill patient: case report and review of the literature. However, a limitation is that there is no placebo arm, so it is difficult to say this decrease is solely from the use of Kayexalate. For example, a recent review article on hyperkalemia failed to mention diuresis at all (Elliott 2010). Lokelma's primary brand-name competitor, Veltassa (patiromer) had a black box warning about drug interactions, which was removed in 2016. This is a good design since we can say that the decrease in K is likely largely from the use of single-dose Kayexalate. medically necessary. † In vitro, LOKELMA has a high affinity for K +, even in the presence of other cations such as calcium and magnesium. Sodium polystyrene sulfonate is a generic drug that also comes as the brand names Kalexate, SPS, and … The drug seems to work better than sodium polystyrene sulfonate (Kayexalate), reducing serum potassium levels within an hour and restoring normal levels after about 2 hours in most patients. Lokelma seems like it has a lot of promise. With … It has a mean particle size of 20 µm and includes no more than 3% of particles with a diameter below 3 µm. The sodium content is approximately 4.1 mmol (100 mg) per gram of the drug. Zirconium silicates are widely used in medical and dental settings and are believed to be generally safe. Consumer; Professional; FAQ; Note: This document contains side effect information about sodium zirconium cyclosilicate. LOKELMA contains 400 mg of sodium in each 5 g dose. There’s a lot of blog posts and podcasts (can take a look on EMCrit 2011 and RebelEM 2015) on their view of low evidence and potential GI side effects of using Kayexalate. However, just recently, we do have some evidence on the efficacy of Kayexalate… and it’s actually in conjunction with some of our own Rush ED pharmacy (shout out to Josh DeMott and Gary Peska). early 2010s. One important caveat of these trials is that Lokelma was studied in patients with CKD with mild hyperkalemia. It is designed to investigate the use of Lokelma in patients with acute hyperkalemia with K>5.8. This study also showed that Lokelma was relatively well tolerated. which is why it can result in hypocalcemia and hypomagnesemia. 2018. Each 5 g of sodium zirconium cyclosilicate contains 400 mg of sodium. *Brand names for sodium polystyrene sulfonate (SPS) include Kayexalate ® and Kionex ®. sorbent column in early dialysis machines for its ability to bind urea. absorption in the GI tract. AZ has suggested that its clinical data indicates Lokelma has a faster onset of action than Veltassa and is more selective, although as of yet there are no head-to-head comparisons of the two treatments. ZS-9, delivered orally, captures potassium ions in the GI tract through its chemical similarity to endogenous potassium channels. The placebo group had a mean reduction 0.3 mEq/L. Mechanism Non-specific organic ion-exchange resin and exchanges sodium for potassium 16 Non-specific organic ion-exchange resin and exchanges calcium for potassium 23 Selective inorganic non-polymer, exchanges sodium, and hydrogen for potassium 24 Location 258 patients with CKD and hyperkalemia received Lokelma 10 grams tid in 48-hour period. On average, onset of action was around 1 hour and median time to achieving normal potassium was 2.2 hours. The percentage of patients who maintained normokalemia between days 8-29 was highest in the Lokelma 15-gram qd group including (36/45 (80%), 45/50 (90%), and 51/54 (94%) for the 5-g, 10-g, and 15-g Lokelma groups compared to placebo 38/82 (46%). There are 4 published studies on the use of Lokelma for treating hyperkalemia in patients with mild hyperkalemia in CKD. Their paper titled, “Single-dose sodium polystyrene sulfonate for hyperkalemia in chronic kidney disease or end-stage renal disease” from 2019 (Link) used retrospective data of 114 CKD/ESRD patients with hyperkalemia.
