A Brief Overview Of The Liposomal Formulation

By Kristen Baird


Among the major areas of care fixated by people is their health. As such, advances in medicines are duly welcome and highly appreciated. Progress in research of various diseases and development of drugs to help curb them is always a good indicator. One such aspect of progress has been noted in liposomal formulation.

There has always existed the problem of ingested drugs being digested before reaching their intended target areas in the body. The process of these formulations was discovered as scientists were looking for a solution to this problem. In this solution, the drug would be closed in and protected by a layer of phospholipids and aqueous solution.

The structural composition of the liposomes was adequately suited for the job at hand. It is composed of a mainly liquid core. This is enveloped by a layer of phospholipids, which could be either synthetic or natural. The drugs to be transported, depending on their chemical composition, would either attach to the core or upper layers without being destroyed or denatured.

Researchers have found the process of formation of these compounds may be critical to their performance. They are formed when strands of phospholipids are put in water, and a given heat amount is directed to them. The composition of the formed liposomes is tested against that of this drug it is intended to carry, so as to determine compatibility and avoid destructive reactions.

Advances like these have led to researchers getting further progress in the field. The most famous result being an anthracycline drug known as Doxorubicin, developed specifically to curb the spread of various variations of cancer. It inserts strains of base RNA and DNA into the malignant cells, and also the topoisomerase enzyme in later stages. This actively inhibits the spread of the disease.

It is due to advances in the medical field that control of many diseases is not a reality. Terminal illnesses previously viewed as a death sentence are now controllable and some even treatable. Research on cancer and liposomes has led to development of anti-cancer drugs an their carriers. The development has brought about continuing tests and usage of doxorubicin, paclitaxel, cisplatin, lipoplatin, aroplatin among others.

Some diseases which were considered deadly can now be mitigated via vaccines. Research in the field of liposomes has led to development of several vaccines which can now be actively used as preventative medicine. Most however are still undergoing rigorous testing. Some of the vaccines created include Inflexal V against influenza, Epaxal for Hepatitis, and Stimuvax for cancer.

The formulation is being investigated on how well it will serve in transportation of dietary supplements to various parts of the body. This testing is inspired by the exceptional success in performance of liposomes in targeted drug delivery. If successful, scientists will use liposomes to transport supplements to various parts of the body where they are required by the body. This procedure has been tried and worked. Therefore, its no longer a risk.
