Absorption, Distribution and Excretion
Oral clodronic acid has a bioavailability of 1-2%. A 200mg intravenous dose reaches a Cmax of 16.1mg/L with an AUC of 44.2mg\*h/L. A 200mg intramuscular dose reaches a Cmax of 12.8mg/L with an AUC of 47.5mg\*h/L. Further pharmacokinetic data for clodronic acid are not readily available. Clodronate is eliminated unchanged in the urine. The renal clearance of clodronate is approximately 90mL/min. Metabolism / Metabolites Clodronate is not metabolized in humans. Clodronate is not metabolized in humans. It can be metabolized intracellularly to a beta-gamma-methylene (AppCp-type) analog of ATP (AppCCl2p), which is cytotoxic to macrophages in vitro. Half Life: Approximately 13 hours. Biological Half-Life The mean plasma half life of clodronate is 5.6h. |

Toxicity Summary
The bisphosphonate group binds strongly to the bone mineral, hydroxyapatite. This explains the specific pharmacological action of these compounds on mineralized tissues, especially bone. The exact mechanism of action of clodronate is not known, however it is known that it does not inhibit protein isoprenylation but can be metabolized intracellularly to a β-γ-methylene (AppCp-type) analog of ATP (AppCCl2p), which is cytotoxic to macrophages in vitro. Inhibition of the ADP/ATP translocase by the metabolite AppCCl2p is a likely route by which clodronate causes osteoclast apoptosis and inhibits bone resorption. Recently, the slime mold Dictyostelium discoideum was shown to take up bisphosphonates by pinocytosis. In these cells, clodronate, but not other pharmacologically active bisphosphonates, was incorporated into adenine nucleotides, which could potentially explain why this bisphosphonate sometimes seems to act differently than the other bisphosphonates. Clodronate, like all biphosphonates, also binds protein-tyrosine-phosphatase. Protein Binding Clodronic acid is 36% protein bound in plasma. |

Pharmacodynamics
Clodronic acid is a first generation bisphosphonate that inhibits osteoclast mediated bone resorption. It has a wide therapeutic index as a large overdose is required for significant toxicity and a long duration of action due to the slow release from bone. Patients should be counselled regarding the risk of hypocalcemia, hypovolemia, renal insufficiency, transient hyperphosphatemia, and transient hyperparathyroidism. |

1、根据实验需要选择合适的溶剂配制储备液 (母液)：对于大多数产品，InvivoChem推荐用DMSO配置母液 (比如：5、10、20mM或者10、20、50 mg/mL浓度），个别水溶性高的产品可直接溶于水。产品在DMSO 、水或其他溶剂中的具体溶解度详见上”溶解度 (体外)”部分;
2、如果您找不到您想要的溶解度信息，或者很难将产品溶解在溶液中，请联系我们;
3、建议使用下列计算器进行相关计算（摩尔浓度计算器、稀释计算器、分子量计算器、重组计算器等）;
4、母液配好之后，将其分装到常规用量，并储存在-20°C或-80°C，尽量减少反复冻融循环。
计算结果:
工作液浓度： mg/mL；
DMSO母液配制方法： mg 药物溶于 μL DMSO溶液（母液浓度 mg/mL)。如该浓度超过该批次药物DMSO溶解度，请首先与我们联系。
体内配方配制方法：取 μL DMSO母液，加入 μL PEG300，混匀澄清后加入μL Tween 80，混匀澄清后加入 μL ddH2O，混匀澄清。
(1) 请确保溶液澄清之后，再加入下一种溶剂 (助溶剂) 。可利用涡旋、超声或水浴加热等方法助溶；
(2) 一定要按顺序加入溶剂 (助溶剂) 。
