Better Drug Delivery Through Liposome

By Irma Farrell


Scientists have been working on improving drug delivery to different parts of the body. Delivery vehicles used in this case have different structures and design. The search for a mechanism to deliver the drugs to a specific area has favored the use liposome. The features that scientists are looking for include specificity with receptors, higher payload, stealth mode operation to enhance its circulatory lifetime, less harmful side effects, efficacy and better uptake.



Liposomes have been subjected to numerous tests over the years with incredible results. Scientists are therefore focusing on the potential of this element. This mechanism beats the traditional methods because it is resistant to enzyme metabolism, responds well during target drug administration and is highly soluble as well.

Their design and structure enable the drugs transported through this means to be readily absorbed. Liposomes offer flexibility where one can control the rate of release of the effective element from the drug. It is able to take a lower dosage which means reduced toxins and consequent side effects. They are thus effective in delivery of gene therapy drugs.

Researchers are narrowing down on the size of liposomes used in drug delivery. They have an effect on efficacy by determining residence time and circulation in the blood. They affect the rate of absorption in to the cell and efficacy during targeting. The ultimate result is effectiveness or failure of a drug. Getting the accurate size of a particle is paramount in ensuring the effectiveness of the drug.

Solution formulation depends on the expertise and experience of the team you are working with. Experience and dedication will deliver solutions that are tailor made for your project. This includes both the liposomal and lipid solutions depending on your specifications. Surfactants and solvents are used to optimize existing solutions.

Elaborate procedures are used to develop the solutions. They are batched, scalable or semi-continuous. State-of-the-art equipment and the latest procedures are used in developing your solutions. This enhances effectiveness and accuracy. They are easy to scale and produce in quantities for industrial use. The solutions are sterilized to purify them. Tangential flows are also used in the purification process. Other services in this package include high-pressure homogenization and extrusion. The process aids in preparation and sizing.

The processes that are scalable include solvent injection, lipid hydration or dispersion, lyophilization and other aseptic processes. There is a package for liposomal analysis that includes among other things analysis of their sizes and distribution, electron microscopy, also known as morphology, zeta potential and encapsulation efficiency. Drug loading is also included in this category if the need arises.

A customized solution is what each client should get from any reliable firm. The firm should offer diverse products that are in line with market demands. Having the same developer manufacture your products is recommended. There are reduced chances of variations or errors in composition.

Liposome is preferred because it avoids detection by body enzymes. It is favored because of its nature to target specific areas. Drugs that are naturally toxic will be delivered easily using a specific mechanism. This specificity will be designed during construction.
