Over the years, medical science has been continuously evolving to accommodate any changes in the medical landscape. It does not cease from looking for solutions and treatments of various diseases. The discovery of liposome is among the most remarkable breakthroughs in the industry. This is used to aid drug intake to enhance its efficiency, increase success rate in organ transplant surgery and treat several medical malfunctions.
Liposomes are microscopical vesicles developed in an artificial environment like a laboratory. These are composed of phospholipids that are naturally produced or extracted from another source. Its outer wall has similar composition to that of a cell wall. This allows direct interaction between the cells and the liposomes. These tiny, spheroid-shaped bubbles are typically watery in its core.
The most common use of this structure is to introduce medicines to the patient's body more effectively. The unique property of the vesicles allow drugs to be delivered in specific parts of the body through diffusion. With its double-layered membranes, the vesicle can carry hydrophobic drugs. This can also be used to carry biological agents like antibodies to targeted parts in the patient's body.
The spheroid bubbles can also extend the delivery time for the drugs while keeping its potency. The bi-layered bubble slowly releases the drugs over a span of time. Thus, side-effects may be reduced. Since the vesicle only releases the medication to the affected tissues, it can also help maximize the effects of the drugs.
The vesicles are also believed to be an effective cancer fighting agent. The spheroids can mark the cancer cells. It can also slip right to the tumor by going through the blood flow. This stays in the bloodstreams as well because of its miniature size and its property that is similar to the blood vessels. The drug vessels cannot pass through the endothelial wall as opposed to cancer cells, which are naturally leaky.
Autoimmune diseases may also be combated by using the spheroids. In a transplant surgery, the body usually identifies the newly harvested organ to be a foreign entity. The body's natural protection, the immune system, may attack the organ in an attempt to prevent possible infestation. This could lead to transplant rejection. The artificial lipid is used to suppress the function of the immune system and slow down its progress.
The vesicles are not spontaneously produced, though. There are various methods used to create these drug vessels according to its function and purpose. Its method of dissemination must be considered as well as the type of materials that will be transported.
These vesicles come in various sizes. The vessels are typically small for the white blood cells to easily engulf the bubbles before the drug it carries can be released. Prior to its production, the size and numbers of vesicles to be created have to be determined. Possibilities of reproduction must also be anticipated.
If there is one thing that could hold back medical experts from using liposome, it would be the production expenses. At present, mass production is not feasible since the vessels may not last after it has been produced. There were instances of unintentional mixing of drugs and cases of instability as well. Other than that, nobody can argue of the wonderful benefits this breakthrough promises.
