Bicalutam >DRUG INTERACTIONS ( 7)].
Casomax undergoes stereospecific metabolism. The S (inactive) isomer is metabolized primarily by glucuronidation. The R (active) isomer also undergoes glucuronidation but is predominantly oxidized to an inactive metabolite followed by glucuronidation. Both the parent and metabolite glucuronides are eliminated in the urine and feces. The S-enantiomer is rapidly cleared relative to the R-enantiomer, with the R-enantiomer accounting for about 99% of total steady-state plasma levels.
Pharmacokinetics of the active enantiomer of Casomax in normal males and patients with prostate cancer are presented in Table 3.

Dosage Adjustment In Hepatic Impairment
No dosage adjustment is necessary for patients with mild to moderate hepatic impairment. In patients with severe liver impairment (n=4), although there was a 76% increase in the half-life (5.9 and 10.4 days for normal and impaired patients, respectively) of the active enantiomer of Casomax, no dosage adjustment is necessary .

In prostate cancer, the cancer cells need the male hormone testosterone to grow and multiply well. Hormone treatments like Casomax block the effect of testosterone on prostate cancer cells. This slows down the growth of the cancer. Casomax also helps to reduce symptom 'flares' and side-effects from other treatments which may be used for the cancer, or following surgery.

Casomax is a hormonal therapy drug used to treat prostate cancer. It is best to read this information with our general information about hormonal therapies and the type of cancer you have.
Casomax is given as tablets. Your cancer doctor, nurse or pharmacist will tell you how often you will have it.
Like all cancer drugs, Casomax can cause side effects. Some of the side effects can be serious, so it is important to read the detailed information below.
Your healthcare team can give you advice on how to manage any side effects. Tell your doctor or nurse straight away if you feel unwell or have severe side effects, including any we do not mention here.
Rarely, side effects may be life-threatening. Your cancer doctor or nurse can explain the risk of these side effects to you.
If you need medical attention for any reason other than cancer, always tell the healthcare staff that you are having this treatment.
How should I take Casomax (Casodex)?
Follow all directions on your prescription label. Your doctor may occasionally change your dose. Do not take this medicine in larger or smaller amounts or for longer than recommended.
Casomax is usually taken once per day in the morning or evening. You may take the medicine with or without food. Try to take the medication at the same time each day.
Casomax is given as part of a combination prostate cancer treatment with another medicine called a luteinizing (LOO-tee-in-ize-ing) hormone-releasing hormone, or LHRH. These medicines prevent the testicles from producing testosterone.
Treatment with Casomax and LHRH is usually started at the same time. Follow your doctor's instructions.
LHRH is given as an injection or a tiny implant injected through a needle under the skin around your navel. LHRH injections are given at intervals such as once every 4 weeks. Follow your doctor's instructions.
You should not stop using Casomax unless your doctor tells you to.
While using Casomax, you may need frequent blood tests.
Store at room temperature away from moisture and heat.
Read all patient information, medication guides, and instruction sheets provided to you. Ask your doctor or pharmacist if you have any questions.
Important: Casomax can sometimes cause other side-effects such as breathing problems and allergic reactions. Although these occur less commonly than the ones listed above, they are symptoms that you should tell your doctor about as soon as possible.
If you experience any other symptoms which you think may be due to the tablets, please speak with your doctor or pharmacist for further advice.

Bicalutam > Casomax is a non-steroidal androgen receptor inhibitor. It competitively inhibits the action of androgens by binding to cytosol androgen receptors in the target tissue. Prostatic carcinoma is known to be androgen sensitive and responds to treatment that counteracts the effect of androgen and/or removes the source of androgen.
When Casomax is combined with LHRH analog therapy, the suppression of serum testosterone induced by the LHRH analog is not affected. However, in clinical trials with Casomax as a single agent for prostate cancer, rises in serum testosterone and estradiol have been noted.
In a subset of patients who have been treated with Casomax and an LHRH agonist, and who discontinue Casomax therapy due to progressive advanced prostate cancer, a reduction in Prostate Specific Antigen (PSA) and/or clinical improvement (antiandrogen withdrawal phenomenon) may be observed.
- Gynecomastia (swelling of the breast tissue) has mostly been reported in trials of Casomax using the 150 mg daily dose. The frequency of gynecomastia with 50 mg daily is rare
- Casomax may be given days or weeks before starting an injectable medication known as a LHRH agonist (example: leuprolide acetate, Lupron® or Eligard®). The timing is important to prevent tumor flare.
- A pharmacist should ALWAYS review your medication list to ensure that drug interactions are prevented or managed appropriately
- Clinical trials may exist for prostate cancer. Ask your doctor if any studies are currently enrolling in your area. If not, go to clinicaltrials.gov to search for other centers offering study medications
Renal impairment (as measured by creatinine clearance) had no significant effect on the elimination of total Casomax or the active R-enantiomer.
Casomax is not indicated for use in pregnant women. There is no information available on the presence of Casomax in human milk, or on the effects on the breastfed infant or on milk production. Casomax has been detected in rat milk.
Where can I get more information (Casodex)?
Your pharmacist can provide more information about Casomax.
Why is this medication prescribed?
Casomax is used with another medication (gonadotropin-releasing hormone (GnRH) agonists; such as leuprolide or goserelin) to treat metastatic prostate cancer (cancer that started in the prostate and has spread to other parts of the body). Casomax is in a class of medications called nonsteroidal antiandrogens. It works by blocking the effect of androgen (a male hormone), to stop the growth and spread of cancer cells.
