Azarest 300mg (Azacitidine): Onureg Alternative & Safety Guide

Azarest 300mg is an oral tablet form of azacitidine, made by Everest Pharmaceuticals. It is the generic version of Onureg. Doctors use it to keep adults with acute myeloid leukemia (AML) in remission after chemotherapy. It is not approved for myelodysplastic syndrome (MDS), and it cannot replace the azacitidine injection.

Description

Researching an azacitidine tablet? Looking for an Onureg alternative? Azarest is an oral tablet. It contains azacitidine, the same active ingredient sold under the brand name Onureg. Everest Pharmaceuticals makes it in Bangladesh, in 300mg film-coated tablets, at a WHO-GMP certified facility.

Azacitidine also comes as an injection, sold under the brand name Vidaza, and it’s easy to confuse the two. The injection and the tablet are not the same treatment. Each one treats a different condition, at a different dose, on a different schedule, and the body absorbs them in its own way.

Azarest, the tablet, has one approved use. It is for adults with acute myeloid leukemia who reached remission after intensive chemotherapy, and who cannot go on to a stem cell transplant or further intensive treatment. Azarest is not approved for myelodysplastic syndromes (MDS).

A trial once tested the tablet in MDS patients. It was stopped early. More patients died, and more serious side effects appeared, in the group taking the tablet than in the group taking a placebo. Sepsis was the most common cause of death.

Several other Azarest listings online get this wrong. Confirm which form your oncologist actually prescribed before you order.

Azarest ships worldwide through a Named Patient Program, in places where the drug is not locally registered. AML sits alongside other blood cancers we cover; see our Leukemia & Lymphoma treatments for the full list.

Clinical Expert Insight

“The question I hear most is whether this tablet is the same as the azacitidine injection. It isn’t, and the difference is not small. The tablet is absorbed differently and dosed differently, and giving one at the other’s dose has led to deaths in reported cases. I write the exact product name on every prescription because of it.

Most of my patients here share a pattern: older, in remission after a hard round of chemotherapy, and either not fit for a transplant or unwilling to go through one. This tablet lets them stay in remission longer, taken at home instead of through repeated hospital visits. When families ask about committing to fourteen days of pills each month, I show them the QUAZAR trial numbers. The survival gain was substantial.

Nausea catches people off guard the most. I start an anti-sickness tablet thirty minutes before the first dose, every time, for the first two cycles. I don’t wait to see if a patient needs it, because by the time nausea shows up, it’s harder to control. I also watch the blood count closely. Low neutrophils are common in the first two cycles, so I recheck every two weeks. If the count is too low on day one of a new cycle, we simply wait.”

Azarest Uses and Clinical Safety Protocols

Precise Indications & Eligibility

• Keeps AML in remission. For adults who reached a first remission after strong chemotherapy, but can’t go on to a stem cell transplant or more intense treatment.
• Who was studied. The main trial only enrolled patients 55 or older. They had reached remission within the last four months. None could have a transplant.
• Not for MDS. A separate trial tested the tablet in MDS patients. It stopped early for safety reasons. Doctors don’t recommend it for MDS outside a study.
• Not swappable with the injection. The tablet and the injection are absorbed differently and dosed differently. Mixing them up can cause serious harm, or simply not work.
• No gene test needed. Some of our other cancer pills need a positive gene test first. This one doesn’t. Eligibility here depends on your remission status and treatment history.

Mechanism of Action, Pharmacokinetics & Administration

Azacitidine looks like a natural piece of RNA and DNA (doctors call this a nucleoside analog). Once inside a cell, it gets built into both. At low doses, it blocks an enzyme called DNA methyltransferase. This flips back on genes that had been shut off inside leukemia cells. Those genes normally control healthy cell growth. At higher doses inside the cell, azacitidine turns toxic to fast-growing cells, including any leukemia cells left after chemo.

• Absorption: taken by mouth. Peak blood levels come within about an hour.
• Why the forms aren’t interchangeable: less of the oral dose reaches your blood than an IV or shot would, which is why the tablet and the shot use different doses.
• Missed or vomited dose: if you miss a dose or take it late, take it the same day if you can, then go back to your normal time the next day. Never take two doses in one day to make up for it. If you vomit after a dose, don’t repeat it. Just take your next normal dose on schedule.
• Administration: 300mg by mouth, once a day, Days 1 to 14 of each 28-day cycle. Take it with or without food. Swallow it whole. Don’t cut, crush, or chew it.
• Antiemetic prophylaxis: take an anti-nausea pill 30 minutes before each dose, for the first 2 cycles. You can often stop after that, if you had no nausea.
• Neutrophil check before each cycle: your doctor checks a blood count called your neutrophil count before you start. If it’s too low on Day 1, the cycle is delayed until it recovers.
• Handling: this drug needs careful handling. If tablet powder touches your skin, wash it off right away with soap and water. If it reaches your eyes or mouth, rinse with water, and keep tablets in their own container.

Supply arithmetic. Each cycle needs 14 tablets: one a day for 14 days, then 14 days off. Plan for one pack per cycle when you order, since a single pack does not stretch across a full month.

Adverse Event (AE) Management Table

Monitoring schedule. Blood tests happen every 2 weeks for your first 2 cycles. After that, they happen before each new cycle starts. Lower your dose for low counts? Testing goes back to every 2 weeks for 2 more cycles. About 1 in 3 patients paused treatment at some point, usually for low neutrophils. About 1 in 7 needed a lower dose.

Common reactions patients should expect and report. Nausea and vomiting are the top complaints, which is why anti-nausea medicine is built into the first two cycles. Diarrhea, tiredness, and a smaller appetite are common too, and usually manageable. Tell your doctor right away about any fever, signs of infection, or odd bruising, since these can signal that your blood counts are low.

Clinical Efficacy: QUAZAR AML-001

QUAZAR AML-001 was a large trial across many countries. It was randomized, double-blind, and placebo-controlled. It enrolled 472 patients, all 55 or older, all in a first remission after chemo, and none able to have a transplant. Patients were split evenly between oral azacitidine and a placebo, both taken for 14 days of each 28-day cycle.

Median survival was 24.7 months with oral azacitidine, compared with 14.8 months with placebo — almost a ten-month gap (hazard ratio 0.69, p=0.0009).

Patients also stayed in remission longer on oral azacitidine. This held true whether or not tiny traces of leukemia, called MRD, were still found in their blood at the start. Some patients with MRD even cleared it during treatment.

Quality of life held steady during treatment, despite the daily pills and the stomach side effects listed above.

This trial specifically covered patients who couldn’t have a transplant. It didn’t test the pill as a substitute for standard treatment in patients who could handle more intensive care.

Drug Interactions & Special Handling

Azacitidine interacts with fewer drugs than the targeted pills elsewhere in our catalog. It isn’t broken down by the liver enzymes that cause most drug interactions. It also isn’t affected by a transporter called P-glycoprotein, which changes how many other drugs are absorbed. So the usual interaction checks matter less here.

A few things your oncologist should know about:

• Heartburn pills (PPIs). Taking omeprazole with azacitidine raises azacitidine levels in your blood. There’s no formal dose change for this yet, but your doctor should know.
• Other drugs that lower blood counts. Combining these with azacitidine adds to the risk of low counts.
• Live vaccines. You, and sometimes people you live with, may need to skip certain live vaccines during treatment. Check with your care team first.
• Careful handling. Don’t cut, crush, or chew tablets. Wash your skin right away if you touch what’s inside one.

Precautions & Special Populations

• Pregnancy. This drug can harm an unborn baby. Use effective birth control during treatment, if you or your partner could get pregnant.
• Breastfeeding. Not advised during treatment, or for at least 1 week after your last dose.
• Liver problems. No dose change needed for mild or moderate liver trouble. Severe liver trouble hasn’t been studied with this pill yet, so it calls for extra care.
• Kidney problems. Your kidneys clear this drug from your body. Severe kidney trouble raises drug levels a lot, so kidney health matters for your dose and your check-ups.
• Older adults. The main trial only enrolled patients 55 and up. Most of what we know here already fits an older group.
• Storage. Room temperature, original container, away from moisture. Only the patient should touch these tablets without care, since it’s a hazardous drug.

Global Access: Named Patient Program (NPP)

Getting Azarest usually takes four steps:

• A prescription. Your oncologist provides this, plus a short note confirming your remission.
• Some paperwork. A letter explaining medical need, plus your ID.
• A permit. We handle this step with your local drug authority.
• Shipping. Standard delivery applies. Azarest is a tablet, so it needs no cold storage, unlike the shot it’s sometimes confused with, or our Ponaxen (ponatinib) tablets for other leukemias in this catalog.

Frequently Asked Questions (FAQs)

Is Azarest the same as the azacitidine injection (Vidaza)?

No. They share the same active ingredient. But the tablet and the injection are absorbed differently, dosed differently, and approved for different situations. Using one at the other’s dose has led to deaths in reported cases. Always confirm with your oncologist which form you’ve been prescribed.

Can Azarest treat myelodysplastic syndrome (MDS)?

No, and this point gets misstated on other azacitidine tablet listings. The oral tablet is approved for AML maintenance after remission. A trial of the tablet in MDS patients was stopped early, after more serious and fatal events appeared than with placebo, so it’s not recommended for MDS outside a controlled trial. The injectable form is the one studied and used for MDS.

How many tablets do I need per cycle?

Fourteen: one tablet a day, for the first 14 days of each 28-day cycle. A single 14-tablet pack covers one full cycle.

What if I miss a dose, or vomit after taking one?

Missed it, or took it late? Take it the same day if you can, then resume your normal schedule the next day. Never take two doses in one day to catch up. Vomited after a dose? Don’t take a replacement. Just take your next scheduled dose as normal.

Why do I need blood tests so often?

Azarest often lowers your neutrophil and platelet counts. Blood counts are checked every 2 weeks for the first 2 cycles, then before each cycle after that. This catches any drop early, before it becomes a bigger problem.

Is Azarest the same as Onureg?

Same active ingredient, azacitidine, in the same 300mg tablet form. The difference is the manufacturer and where each is registered. Azarest is made by Everest Pharmaceuticals in a WHO-GMP certified facility. Onureg is the FDA-approved originator.

Do I need contraception while taking this medication?

Yes. Azacitidine can harm a fetus. Use effective birth control during treatment, whether you or your partner could become pregnant.

Can I take antacids or PPIs with Azarest?

Tell your oncologist if you’re on a proton pump inhibitor, like omeprazole. It can raise azacitidine levels in your blood. Let your care team decide, rather than adjusting anything yourself.
