Tiludronic Acid

Chemical structure of Tiludronic Acid

Tiludronic acid is a bisphosphonate drug used primarily in the treatment of Paget's disease of bone and other conditions involving abnormal bone metabolism. It is known for its ability to inhibit bone resorption, which is the process by which bone is broken down and its minerals released into the bloodstream.

Mechanism of Action

Tiludronic acid works by binding to hydroxyapatite crystals in the bone matrix, thereby inhibiting the activity of osteoclasts, the cells responsible for bone resorption. This action helps to maintain bone density and reduce the risk of fractures in patients with bone disorders.

Clinical Uses

Tiludronic acid is primarily indicated for the treatment of Paget's disease, a chronic disorder that can result in enlarged and misshapen bones. It may also be used off-label for other conditions that involve excessive bone turnover, such as osteoporosis and certain types of bone metastases.

Administration and Dosage

Tiludronic acid is typically administered orally. The dosage and duration of treatment depend on the specific condition being treated and the patient's overall health status. It is important for patients to follow their healthcare provider's instructions carefully to achieve optimal results.

Side Effects

Common side effects of tiludronic acid include gastrointestinal disturbances such as nausea, vomiting, and diarrhea. More serious side effects can include esophageal irritation and osteonecrosis of the jaw, although these are rare.

Pharmacokinetics

Tiludronic acid is absorbed in the gastrointestinal tract and is primarily excreted unchanged in the urine. Its bioavailability can be affected by food intake, so it is often recommended to take the medication on an empty stomach.
