Flutamerck to Treat Prostate Cancer
The U.S. Food and Drug Administration (FDA) approved the use of Flutamerck in the country on June 1996. It is commercialized under the brand name Eulexin to be used in the therapeutic areas of endocrinology, nephrology, oncology, family medicine, and urology. The approval was based on a study submitted by the pharmaceutical company Schering-Plough, which revealed the effectiveness of Flutamerck for the treatment of locally confined Stage B2-C carcinoma of the prostate in combination with LHRH agonists and radiation therapy.
Flutamerck is prescribed as a tablet to be taken three times a day with a glass of water. Despite the encouraging results of the treatment with Flutamerck, there are also potential side effects associated to it. The most common adverse events include hot flushes and sweats, which affect three out of five men treated (60%), lowered interest in having sex (libido) and problems getting an erection (impotence), which affect about three out of 10 (30%) men but may stop after the end of the treatment, as well as breast tenderness and swelling, which occur in one out of 10 (10%) men treated.
Flutam >About Flutamerck
Before taking Flutamerck
Some medicines are not suitable for people with certain conditions, and sometimes a medicine can only be used if extra care is taken. For these reasons, before you start taking Flutamerck it is important that your doctor knows:
- If you have any problems with the way your liver works.
- If you have a heart condition.
- If you have a rare inherited blood disorder called porphyria.
- If you are taking any other medicines. This includes any medicines which are available to buy without a prescription, as well as herbal and complementary medicines.
- If you have ever had an allergic reaction to a medicine.
Although Flutamerck is effective in treating hirsutism, adverse reactions are very frequent and long-term adherence is poor. In one study over 7 years, of 83 women who took Flutamerck 250 mg/day alone or in combination with an oral contraceptive containing ethinylestradiol 20 micrograms and desogestrel 150 micrograms, 34 had one or more adverse reaction during follow-up, 28 had at least one adverse reaction that was possibly related to the study drug, and 20 withdrew because of adverse reactions, hepatotoxicity being the most troublesome; during follow-up, as many as 59% abandoned the study .
• Be aware that leuprolide acetate is the most common LHRH analog given with Flutamerck.
Flutamerck may cause liver damage that can be serious or life-threatening. Tell your doctor if you have or have ever had liver disease. If you experience any of the following symptoms, call your doctor immediately: nausea, vomiting, loss of appetite, extreme tiredness, flu-like symptoms, muscle aches, soreness, pain in the upper right part of the stomach, yellowing of the skin or eyes, or dark urine.
Keep all appointments with your doctor and the laboratory. Your doctor will order certain blood tests to check how well your liver is working before you begin taking Flutamerck, every month for the first 4 months of your treatment, and periodically for as long as your treatment continues.
Talk to your doctor about the risks of taking Flutamerck.
