Clodronate Liposome Has Numerous Scopes

By Adele Madden


Clodronate is very effective in the treatment of hypercalcemia and cancer metastases to bones. It can significantly reduce the development of new metastases, as well as to decrease the risk of bone fractures, which is very high in such cases. Besides, it may also reduce the pain associated with this disease. Clodronate liposome, also known as clodrosome, seems to be the best way of delivering this compound to tissues.

To be closed in vivo, this effective compound is delivered encapsulated within liposomes. A liposome is lipid-based tiny particle, designed to carry different compounds in form of suspension. It is lately used in many research laboratories, as highly effective way or delivering drugs to various tissues. In this case, to bones and kidneys.

Clodronate liposome suspension should be injected to targeted tissues. While manipulating this type of suspension, some measures of precaution are necessary, such as chemical resistant gloves and clothing, safety goggles and respirators. This compound can be harmful if inhaled, absorbed through skin, swallowed or if it get in contact with your eyes. It causes different irritations, especially to mucous membranes, and you should be very careful with it.

If you get in any type of direct contact with it, make sure to follow the procedure. If it get in contact with your eyes, you should flush them with clean water for some time repeatedly, approximately fifteen minutes or so. If it get in touch with your skin, wash it with water and soap. If you inhale it, go outside on fresh air immediately. For more serious exposures, maybe you should have a respirator or even oxygen nearby. If you swallow it, rinse your mouth and call a doctor.

Macrophages are very important, because they regulate immune reactions and some other, non-phagocytic cells function. Their primary function is to ingest and digest unfamiliar macromolecules and other microorganisms. In order to override their function, they use liposomal encapsulated compounds and drugs.

Liposomes encapsulate clodronate, and they are used for delivering it to tissues, in this case kidneys and bones. They will be ingested and digested by macrophages. After that, active compound will be released and accumulated. This will create macrophage depleted tissues or organs, allowing in vivo research of different functional aspects of macrophages.

Clodronate liposomes application can also be used for suppression of macrophage activity in different models of autoimmune diseases, in gene therapy and similar researches. Although this method is designed especially for in vivo research, it can also be successfully used for depletion of macrophages in vitro.

It is important to keep the suspension at appropriate temperature. It shouldn't be exposed to temperatures above 30 degrees of Celsius, or frozen. The ideal storage temperature is four degrees Celsius, and in this case it can be kept one month in refrigerator. For achieving desired results, the suspension should be kept outside the refrigerator until it reaches room temperature, before injecting it to animals.

It is also important to shake the suspension until it becomes homogeneous. You should shave the skin and cleanse it with alcohol, to make sure it is disinfected. You should use sterile syringe for each animal. If you use the same one, you might get uneven dosages. Follow the procedure for injecting clodronate liposome to your test animals.
