What Is Zytiga and How Does It Work?

Zytiga, with the generic name abiraterone acetate, belongs to a drug class known as androgen biosynthesis inhibitors. To understand how it works, it’s helpful to know the role of androgens (male hormones, including testosterone) in prostate cancer.

The Role of Androgens in Prostate Cancer

Prostate cancer cells depend on androgens as a fuel source. These hormones attach to cancer cells and signal them to grow and spread. Traditional hormone therapy—often called androgen deprivation therapy (ADT)—works by reducing the amount of testosterone produced in the body or blocking its action.

However, in many men with advanced prostate cancer, the disease eventually adapts and continues growing despite low testosterone levels. This stage is called castration-resistant prostate cancer (CRPC).

How Zytiga Works

Unlike standard hormone therapy that targets testosterone mainly produced in the testes, Zytiga works at a deeper level. It blocks an enzyme called CYP17, which is crucial for the body’s production of androgens—not only in the testes, but also in the adrenal glands and even within the tumor itself.

By inhibiting CYP17, Zytiga dramatically lowers androgen levels throughout the body, starving cancer cells of the hormones they rely on. This makes it a powerful option for controlling cancer growth in advanced stages.

FDA-Approved Uses of Zytiga

The U.S. Food and Drug Administration (FDA) has approved Zytiga for use in two specific conditions:

1. Metastatic Castration-Resistant Prostate Cancer (mCRPC):
   • Cancer that has spread to other parts of the body.
   • Continues to grow even when testosterone levels are reduced through standard hormone therapy or surgical removal of the testicles.
2. Metastatic High-Risk Castration-Sensitive Prostate Cancer (mCSPC):
   • Cancer that has spread beyond the prostate.
   • Still responds to hormone therapy, but is considered high-risk because of the extent of spread or aggressiveness of the disease.

The Role of Prednisone

Zytiga is always prescribed with prednisone, a corticosteroid. This is because Zytiga not only reduces testosterone but also disrupts other hormone pathways that can lead to dangerous side effects such as high blood pressure, low potassium, and fluid retention. Prednisone helps balance these effects and makes the treatment safer.

In addition, most men taking Zytiga are also prescribed a GnRH (gonadotropin-releasing hormone) analog, unless they have undergone surgical removal of both testicles. This ensures testosterone suppression remains consistent.

Available Forms and Strengths of Zytiga

When starting Zytiga, many patients wonder about the different pill options and how they fit into daily treatment routines. Fortunately, the medication is available in two tablet strengths, giving doctors flexibility in prescribing based on convenience, insurance coverage, and patient preference.

Form of Zytiga

• Zytiga is manufactured only as an oral tablet.
• Tablets are taken by mouth and must be swallowed whole with water.
• There are currently no liquid or injectable versions of Zytiga available, which makes swallowing ability an important consideration.

Strengths of Zytiga

Zytiga tablets come in two standard strengths:

1. 250 milligrams (mg)
   • Typically prescribed as four tablets taken together once daily to reach the standard 1,000 mg dose.
   • Some patients find this less convenient because of the number of pills.
2. 500 milligrams (mg)
   • Allows patients to take two tablets once daily instead of four.
   • Many doctors prefer prescribing this version for simplicity and to reduce “pill burden.”

Both strengths contain the same active ingredient, abiraterone acetate, and work identically in the body. The choice between them usually comes down to doctor preference, availability at your pharmacy, and insurance coverage.

Brand Name vs. Generic Zytiga

• Brand-name Zytiga has been available since 2011.
• Generic abiraterone acetate tablets were approved by the FDA in 2018 and are now widely available.
• Generics are chemically identical to brand-name Zytiga in strength, safety, and effectiveness, but they are often significantly more affordable.

💡 Tip: If cost is a concern, ask your doctor or pharmacist whether the generic version is available and covered under your insurance plan. Many patients are able to save thousands of dollars per year by switching to the generic.

Packaging and Tablet Appearance

• 250 mg tablets are typically white, oval-shaped pills.
• 500 mg tablets are purple and oval-shaped.
• Packaging may differ depending on whether you receive brand-name or generic Zytiga, but the medication inside works the same way.

Zytiga Dosage Guidelines for Different Conditions

The standard daily dose of Zytiga is 1,000 milligrams (mg), but the way it’s taken and the required prednisone schedule depends on your specific prostate cancer diagnosis. Since Zytiga is always paired with prednisone, it’s important to understand both parts of your treatment.

Standard Zytiga Dose

• 1,000 mg taken once daily
• This can be taken as:
  • Four 250-mg tablets, OR
  • Two 500-mg tablets
• Tablets should be taken at the same time every day, on an empty stomach.

Zytiga with Prednisone: Two Main Scenarios

Your prednisone schedule depends on whether you have metastatic castration-resistant prostate cancer (mCRPC) or metastatic high-risk castration-sensitive prostate cancer (mCSPC).

Here’s a quick comparison:

Condition	Zytiga Dose	Prednisone Dose	Frequency
Metastatic CRPC	1,000 mg once daily	5 mg twice daily	Morning & evening
Metastatic High-Risk CSPC	1,000 mg once daily	5 mg once daily	Usually morning

Why Prednisone Is Required

Prednisone is not just an optional add-on—it plays a critical role in making Zytiga treatment safer. Here’s why:

• Balances hormone changes: Zytiga reduces androgen production, which can throw off other hormone systems. Prednisone helps restore balance.
• Protects against side effects: Without prednisone, patients are more likely to experience high blood pressure, low potassium, fluid retention, and adrenal gland issues.
• Improves tolerability: Taking prednisone with Zytiga often makes the treatment easier to tolerate over long periods.

Individual Adjustments

While the standard Zytiga dose is consistent, doctors may adjust your regimen if:

• You have liver problems (dose may be lowered).
• You develop serious side effects.
• You’re taking medications that interact with Zytiga.
• Your doctor is tailoring prednisone based on other health needs.

💡 Tip for Patients: Always take prednisone exactly as prescribed. Missing doses of prednisone while on Zytiga can increase the risk of dangerous side effects like adrenal insufficiency.

How to Take Zytiga Properly

Taking Zytiga correctly is essential for it to work as intended and to avoid dangerous side effects. Because this medication has strict food and timing requirements, patients need to follow their doctor’s instructions carefully.

1. Food and Timing Rules

Zytiga absorption is highly affected by food. If taken with meals, your body may absorb too much medication, leading to dangerously high drug levels in the blood.

To prevent this:

• No food for at least 2 hours before your dose.
• No food for at least 1 hour after your dose.
• Always take Zytiga on an empty stomach with a full glass of water.

👉 Example: If you plan to take Zytiga at 8:00 a.m., do not eat after 6:00 a.m., take the medication at 8:00 a.m., and wait until 9:00 a.m. before having breakfast.

2. Tablet Administration

• Swallow the tablets whole — do not chew, crush, or split them.
• Take your dose at the same time every day to maintain steady drug levels.
• Always wash the tablets down with a full glass of water.

💡 Pro Tip: Pick a time that fits naturally into your day (such as first thing in the morning) to make the fasting window easier to manage.

3. What If You Have Trouble Swallowing?

Some patients find large tablets difficult to swallow. If that’s the case, speak with your healthcare team. Possible solutions include:

• Swallowing techniques: Place the tablet in your mouth, drink water through a straw, or tilt your head forward while swallowing.
• Pill swallowing aids: Special gel capsules or cups can make swallowing easier.
• Speech therapy consultation: For patients with chronic swallowing difficulties.

⚠️ Do not attempt to crush or dissolve Zytiga tablets yourself, as this may change how the drug is absorbed and could expose caregivers to harmful powder.

4. Daily Routine Guide

Here’s a sample schedule that patients often find helpful:

• 6:00 a.m. – Last snack or meal before fasting period.
• 8:00 a.m. – Take Zytiga with a full glass of water.
• 8:05 a.m. – Take prednisone (with or without food, as advised).
• 9:00 a.m. – Eat breakfast.
• Throughout the day – Stay hydrated and monitor for side effects.
• 8:00 p.m. (if prescribed twice-daily prednisone) – Take evening dose.

This routine can be adjusted depending on your lifestyle and when you prefer to eat, but consistency is key.

5. Missed Doses

• If you miss one dose of Zytiga: Take your regular scheduled dose the next day.
• Do not double up to make up for missed tablets.
• If you miss multiple doses: Call your doctor before resuming treatment.

Factors That May Affect Your Zytiga Dosage

While the standard dose of Zytiga is 1,000 mg once daily, not every patient will take the same amount throughout their treatment journey. Your doctor may adjust your dose depending on how your body responds and any health conditions you have.

Here are the main factors that can influence your dosage:

---

1. Liver Function

Your liver plays a central role in breaking down (metabolizing) Zytiga. If your liver isn’t working properly, the drug can build up in your system, increasing the risk of side effects.

• Mild liver problems – Your doctor may allow you to continue at the regular dose but will monitor you closely.
• Moderate liver impairment – A reduced dose may be prescribed.
• Severe liver disease – Zytiga may not be safe, and alternative treatments may be recommended.

👉 Patients will undergo regular liver function tests (LFTs) while on treatment. If test results show rising liver enzymes, your doctor may pause treatment or reduce the dose.

---

2. Other Health Conditions

Certain medical conditions may also influence dosing decisions:

• Heart disease or high blood pressure – Since Zytiga can raise blood pressure and cause fluid retention, patients with heart conditions may need closer monitoring.
• Adrenal issues – Because Zytiga lowers natural steroid production, patients with adrenal insufficiency require extra caution and may need adjusted prednisone support.
• Kidney disease – While Zytiga is not primarily cleared by the kidneys, overall health and medication tolerance still matter.

---

3. Medication Interactions

Zytiga can interact with many drugs, changing how either medication works. This is why it’s critical to provide your doctor with a complete list of everything you take, including prescriptions, over-the-counter drugs, and supplements.

Some examples:

• Blood thinners (e.g., warfarin) – May increase bleeding risk.
• Heart medications (e.g., digoxin) – Can have altered effects when combined.
• Certain antidepressants or seizure medications – May change how Zytiga is processed.
• Herbal supplements – Especially St. John’s Wort, which can lower Zytiga’s effectiveness.

💡 Pro Tip: Bring all your medication bottles to your doctor’s appointment (“brown bag review”) to ensure nothing is overlooked.

---

4. Side Effects and Tolerance

Not every patient tolerates Zytiga the same way. If you experience:

• Severe fatigue
• Low potassium levels
• Elevated blood pressure
• Abnormal liver tests

…your doctor may reduce the dose or temporarily stop treatment until your body stabilizes.

---

5. Treatment Goals and Cancer Progression

Your oncologist will continuously evaluate whether Zytiga is working for you. If the cancer progresses or PSA levels rise despite treatment, they may:

• Switch you to another prostate cancer medication (such as Xtandi, Erleada, or chemotherapy).
• Recommend clinical trials for newer therapies.
• Adjust supportive medications like prednisone.

---

⚠️ Never adjust your Zytiga dose on your own. All changes should be guided by your oncologist based on test results and your overall health.

Managing Missed Doses of Zytiga

Life happens—sometimes you may forget to take your medication on time. With Zytiga, it’s very important to know what to do if you miss a dose because taking too much or too little can affect both safety and treatment effectiveness.

---

What to Do If You Miss One Dose

• Skip the missed dose.
• Do not double up. Taking two doses close together could increase your risk of serious side effects.
• Simply take your next regular dose at the usual time the following day.

👉 Example: If you normally take Zytiga at 8:00 AM but forget until 2:00 PM, skip that day’s dose and take your regular dose the next morning at 8:00 AM.

---

What to Do If You Miss Multiple Doses

• Call your healthcare provider immediately.
• They may ask you about your missed doses, current symptoms, and treatment history before advising next steps.
• Do not restart on your own. Sometimes, depending on how many doses were missed, your oncologist may want to run blood tests before resuming treatment.

---

Prevention Strategies for Staying on Track

Since Zytiga is a long-term treatment, building strong medication habits is essential. Here are proven strategies:

1. Set daily alarms on your phone or smart speaker.
2. Use a pill organizer with compartments for each day of the week.
3. Pair your medication with a routine habit (e.g., always take it right after brushing your teeth in the morning).
4. Download medication reminder apps like Medisafe or MyTherapy.
5. Keep Zytiga in a visible location—but away from direct sunlight, moisture, and out of reach of children.
6. Travel tip: Always carry an extra supply in your hand luggage when flying, in case your checked bags get delayed.

---

Why Missed Doses Matter

Consistency is key because:

• Missing doses may allow cancer cells to regain activity and grow.
• Irregular dosing can make it harder for your doctor to know if Zytiga is truly effective.
• Doubling up on doses can increase risks like liver problems, dangerously high blood pressure, or low potassium levels.
