Enzilix 40mg Tablet 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 Enzilix 40mg Tablet

Enzilix 40mg Tablet 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 Enzilix 40mg Tablet 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 Enzilix 40mg Tablet, 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 Enzilix 40mg Tablet 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 Enzilix 40mg Tablet

Enzilix 40mg Tablet is used to treat advanced prostate cancer. The detailed uses of Enzilix 40mg Tablet are as follows:

  • Non-metastatic castration-resistant prostate cancer (nmCRPC): Enzilix 40mg Tablet 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

Enzilix 40mg Tablet helps slow the progression of advanced prostate cancer and supports long-term disease management. The key benefits of Enzilix 40mg Tablet are as follows:

  • Slows Cancer Progression: By blocking the hormones that fuel tumour growth, Enzilix 40mg Tablet 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 Enzilix 40mg Tablet 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.

Directions for Use

  • Enzilix 40mg Tablet can be taken with or without food or as advised by your doctor.
  • Follow your doctor's instructions on the dosage and timing of this medication.
  • Swallow Enzilix 40mg Tablet as a whole with a glass of water.
  • Do not crush, break, or chew it.

How Enzilix 40mg Tablet Works

Enzilix 40mg Tablet 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. Enzilix 40mg Tablet 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.
