์์ฉ ๊ธฐ์ : Tiludronate works by inhibiting osteoclastic bone resorption. * **Binding:** The drug has a high affinity for calcium and binds strongly to **hydroxyapatite** crystals in the bone matrix, preferentially at sites of active bone turnover (cancellous bone > cortical bone). * **Cellular Uptake:** During bone resorption, osteoclasts take up the bisphosphonate. * **Intracellular Mechanism:** As a non-nitrogenous bisphosphonate, tiludronate is intracellularly metabolized into a non-hydrolyzable **ATP analogue**. * **Apoptosis:** This toxic ATP analogue accumulates within the osteoclast โ disrupts cellular energy metabolism (inhibiting ATP-dependent intracellular enzymes) โ induces **osteoclast apoptosis** (programmed cell death). * **Result:** Decreased osteoclast function and lifespan lead to a net reduction in bone resorption and stabilization of bone remodeling.

- Clinical Efficacy (improvement in lameness)
- Serum Calcium levels
- Adverse Effects (particularly within the first 4 hours after dosing, watching for colic or muscle tremors)
๊ณผ์ฉ๋
Limited information is available regarding massive overdose. * **Clinical Signs:** The manufacturer reports that doses of 3X the therapeutic dose in horses caused an increased frequency of adverse effects, particularly **signs of colic** and **muscle tremor**. * **Treatment:** Intravenous **calcium administration** should be considered for signs associated with acute hypocalcemia (e.g., severe muscle fasciculations/tremors). Conventional colic treatments are recommended if gastrointestinal signs persist.
