Medical Breakthroughs From Liposomal Formulation

By Kristen Baird


Progress in research and development in the medical field is always a good indicator. Hope is bestowed when such advances take place as they signal for better and new ways to deal with diseases. Among such progress is the advent of liposomal formulation in aiding in quicker and better ways of dealing with several ailments.

The formulation is a rightful step in the advancement of drugs. The procedure was discovered to curb the unwanted effects of drugs being exhausted before reaching the target areas. The initial phase of the process involves encapsulating the drug in a layer of digestible and healthy phospholipids. There were several options on the table, but after further research, liposomes were found to be the most favorable carriers.

The simplicity of the liposomes' structural composition is key to its performance. They are made up of an aqueous solution which is engulfed in a strengthened mesh of either natural or synthetic phospholipids. The advantage of this is that it can fuse non-reactively with both hydrophilic and hydrophobic drugs, each attaching to the element it does not react to.

The core structure of liposomes is what causes them to be preferred among researchers of various fields and disciplines. They are formed when phospolipids are immersed in water and a specific amount of heat directed toward them. To determine if it is an appropriate carrier for a given drug, the chemical composition should be bench-marked against that of the drug, so as to avert reactions.

When such discoveries are made, researchers are eager to push it so as to find out if the new discovery can lead to better drugs. IN this case it did. An anthracycline drug known as Doxorubicin was developed to help control the spread of cancer. This is achieved by injecting stains of base DNA and RNA into the malignant cells. The enzyme topoisomerase is also injected at a later stage. These procedures inhibit replication of the cells actively controlling their growth.

Research and development has been kicked into top gear with the discovery and advancement of this formulation. There are high expectations from various areas on the development of drugs to help the fight against most terminal illnesses. There has been consistent research in developing anti-cancer drugs in the recent past. Drugs such as doxorubicin, paclitaxel, cisplatin, lipoplatin and aroplatin have been developed and testing is ongoing for the same purpose.

There has been considerable progress in the development of vaccines for diseases which do not have known cures. Such include hepatitis A, which now has a vaccine, Epaxal, under development. Inflexal V is a vaccine developed for several types of influenza especially in children. A vaccine for cancer known as Stimuvax is also in the offering.

Another point of progress thanks to this formulation has been in delivery of dietary supplements. It is still a new area under testing, but has great promise considering the level of success the formulations has garnered from targeted drug delivery. The process of the formulation is hence referred to as a new era of medical advances.
