[Posted 07/21/2011]ISSUE:FDA notified healthcare professionals and patients about its ongoing review of data from published studies to evaluate whether use of oral bisphosphonate drugs is associated with an increased risk of cancer of the esophagus. FDA has not concluded that taking an oral bisphosphonate drug increases the risk of esophageal cancer. There are insufficient data to recommend endoscopic screening of asymptomatic patients. FDA will continue to evaluate all available data supporting the safety and effectiveness of bisphosphonate drugs and will update the public when more information becomes available.
BACKGROUND:Oral bisphosphonates are commonly used for the prevention and treatment of osteoporosis as well as to treat other bone diseases such as Paget's disease. There have been conflicting findings from studies evaluating the risk of esophageal cancer. Esophagitis and other esophageal events have been reported, particularly in patients who do not follow the specific directions for use of oral bisphosphonates. See the Data Summary in the Drug Safety Communication for additional details at: Web Site.
RECOMMENDATION:Patients should talk with their healthcare professional about the benefits and risks of taking oral bisphosphonates and how long they should expect to take them. Patients should talk with their healthcare professional if they develop swallowing difficulties, chest pain, new or worsening heartburn, or have trouble or pain when swallowing. Patients should be instructed to carefully follow the directions for use of the oral bisphosphonate drug they are prescribed. For more information visit the FDA website at: Web Siteand Web Site.
WHY is this medicine prescribed?
Tiludronate is used to treat Paget's disease of bone (a condition in which the bones are soft and weak and may be deformed, painful, or easily broken). Tiludronate is in a class of medications called bisphosphonates. It works by preventing bone breakdown and increasing bone density (thickness).
HOW should this medicine be used?
Tiludronate comes as a tablet to take by mouth. It is usually taken on an empty stomach once a day for 3 months. This treatment may be repeated if symptoms come back or worsen after some time has passed. Take tiludronate at around the same time every day. Follow the directions on your prescription label carefully and ask your doctor or pharmacist to explain any part you do not understand. Take tiludronate exactly as directed. Do not take it more or less often or for a longer period of time than prescribed by your doctor.
Take tiludronate with a full glass (6 to 8 ounces [180 to 240 milliliters]) of plain water. Do not take tiludronate with any other liquid, including mineral water. Do not eat or drink for 2 hours before or 2 hours after you take tiludronate. Do not lie down for at least 30 minutes after taking this medication.
Tiludronate controls Paget's disease of bone only when it is taken as prescribed. Do not stop taking tiludronate without talking to your doctor.
