Obnyx Capsule is used to treat prostate cancer. It contains Enzalutamide, an androgen receptor blocker (inhibitor) that blocks testosterone from reaching prostate cancer cells. Most prostate cancers require testosterone to grow; this can slow the growth of the cancer and may shrink it. Enzalutamide is only for use in men. Men using this medication must use effective birth control whenever they have sex during their treatment and for three months after their final dose.

About Obnyx Capsule

Obnyx Capsule is a prescription medicine primarily used to treat advanced types of prostate cancer. It is designed for prostate cancer that has spread to other parts of the body or no longer responds to medical or surgical treatments that lower testosterone. This medicine works by stopping hormone signals that would otherwise allow cancer cells to grow and multiply.

To get the best results, you must take Obnyx Capsule consistently every single day at the same time as prescribed. You can take this medicine with or without food, making it easy to fit into your daily routine. Making small adjustments to your daily life, such as incorporating gentle physical activity and eating a balanced diet, can help your body handle the therapy more effectively.

While taking this medicine, you may experience common side effects like hot flashes, fatigue, and joint discomfort. However, you must contact your doctor immediately if you experience severe symptoms such as sudden confusion, severe dizziness, chest pain, or seizures.

Before starting Obnyx Capsule, you must talk to your doctor if you have a history of seizures, brain injury, stroke, heart disease, or high blood pressure. Do not take this if you are allergic to Obnyx Capsule or any of the inactive ingredients contained in the tablet.

This medicine can interact with other drugs like blood thinners and certain heart medicines, which may change how well they work or increase side effects. It is not approved for use in women, and pregnant or breastfeeding individuals must not handle or touch the tablets. Elderly patients should talk to their doctor to closely monitor their physical strength and heart health, taking extra precautions against falls due to the combined risk of dizziness, fatigue, and bone weakening.

Uses of Obnyx Capsule

Obnyx Capsule is used to treat advanced prostate cancer. The detailed uses of Obnyx Capsule are as follows:

  • Non-metastatic castration-resistant prostate cancer (nmCRPC): Obnyx Capsule treats prostate cancer that is 'castration-resistant' (meaning it continues to grow despite very low testosterone levels) and has not yet spread to other body parts on scans.
  • Metastatic castration-sensitive prostate cancer (mCSPC): Treats prostate cancer that has spread to other body parts (such as bones or lymph nodes) but still responds to medical or surgical treatments that lower testosterone.
  • Metastatic castration-resistant prostate cancer (mCRPC): Treats advanced prostate cancer that has spread to other parts of the body and no longer responds to initial testosterone-lowering treatments.

Key Benefits

Obnyx Capsule helps slow the progression of advanced prostate cancer and supports long-term disease management. The key benefits of Obnyx Capsule are as follows:

  • Slows Cancer Progression: By blocking the hormones that fuel tumour growth, Obnyx Capsule helps slow the progression of advanced prostate cancer, reduces cancer-related pain, and helps prevent the disease from spreading further.
  • Prolongs Survival and Delays Intensive Treatment: Clinical studies have shown that Obnyx Capsule helps prolong survival and may delay the need for more intensive treatments, such as chemotherapy, allowing many patients to maintain their independence and daily routine for longer.

Here are the precise steps to cope with diarrhoea caused by medication usage:
  • Inform Your Doctor: Notify your doctor immediately about your diarrhoea symptoms. This allows them to adjust your medication or provide guidance on managing side effects.
  • Stay Hydrated: Drink plenty of fluids to replace lost water and electrolytes. Choose water, clear broth, and electrolyte-rich drinks. Avoid carbonated or caffeinated beverages to effectively rehydrate your body.
  • Follow a Bland Diet: Eat easy-to-digest foods to help firm up your stool and settle your stomach. Try incorporating bananas, rice, applesauce, toast, plain crackers, and boiled vegetables into your diet.
  • Avoid Trigger Foods: Steer clear of foods that can worsen diarrhoea, such as spicy, fatty, or greasy foods, high-fibre foods, and dairy products (especially if you're lactose intolerant).
  • Practice Good Hygiene: Maintain good hygiene to prevent the spread of infection. To stay healthy, wash your hands frequently, clean and disinfect surfaces regularly, and avoid exchanging personal belongings with others.
  • Take Anti-Diarrheal Medications: If your doctor advises, anti-diarrheal medications such as loperamide might help manage diarrhoea symptoms. Always follow your doctor's directions.

Here are the steps to manage Joint Pain caused by medication usage:
  • Please inform your doctor about joint pain symptoms, as they may adjust your medication regimen or prescribe additional medications to manage symptoms.

  • Applying heat or cold packs to the affected joint can help reduce pain and inflammation.
  • Please track when joint pain occurs and any factors that may trigger it, and share this information with your doctor to help manage symptoms.
  • If your joint pain is severe or prolonged, consult a doctor to rule out any underlying disorders that may require treatment.
  • Wear compression garments like stockings, sleeves, or gloves to apply pressure and help stop fluid from building up, especially after the swelling goes down.
  • Move around and do exercises to help the fluid circulate, especially in swollen limbs. Ask your doctor for specific exercises.
  • Raise the swollen area above your heart level several times a day, even while sleeping, to help reduce swelling.
  • Gently massage the swollen area with firm but not painful pressure.
  • Keep the swollen area clean and moisturized to prevent injury and infection.
  • Reduce salt intake to help prevent fluid from building up and worsening the swelling, as advised by a doctor.
  • If the swelling does not get better after a few days of home treatment or worsens, consult your doctor right away.

How Obnyx Capsule Works

Obnyx Capsule contains enzalutamide, which belongs to a group of medicines called androgen receptor inhibitors. Male hormones, such as testosterone, act as fuel for prostate cancer cells by attaching to specific receptors on the cancer cells and stimulating their growth. Obnyx Capsule blocks these androgen receptors, preventing testosterone and other male hormones from attaching to them. This interrupts the growth signals that cancer cells rely on, helping slow the spread of prostate cancer, shrink tumours, and reduce prostate-specific antigen (PSA) levels.

FAQs

Obnyx Capsule is only for use in men. Women should not take this medication, especially if they are or may become pregnant or are breast-feeding.
In some cases, Obnyx Capsule may cause decreased fertility in men. However, you should not assume that your female partner cannot become pregnant. Please discuss with your doctor if you have any concerns.
