Better Drug Delivery Through Liposome

By Irma Farrell


Drug delivery has bothered scientist with increasing need for specificity. Vehicles used in delivery require different designs and structures to make them effective. Liposome is favored because it has shown an admirable ability to be specific unlike traditionally used vehicles. Scientist are looking at something that has a high payload, reduces circulatory time through stealth operation, enhances uptake, has reduced side effects and is specific on receptors.

Many years of testing have revealed the benefits contained in liposomes. The findings have seen an increased focus on the potential of the drug. Some of the reasons they are preferred over traditional methods include protection form enzyme metabolism, higher rate of solubility and their ability to target specific areas.

The structure and design of liposomes make drugs that are encapsulated using the compounds to be easily absorbed in the body. They are flexible making it easier to control release of important elements in the body. There is reduced toxicity because lower dosages are administered. This means that side effects are reduced. It is the preferred mode of delivering 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.

The processes used in developing the solutions vary between scalable, batched and semi-continuous. Experience and uses of the latest manufacture processes and equipment ensures that the solutions are accurate and effective. They can be scaled to industrial quantities. The processes that will benefit clients include sizing and preparation through extrusion and high-pressure homogenization. Purification is done by filtration using sterilization and tangential flows.

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 track record of quality delivery and commitment to meets the needs of each client define a reliable company. It also is able to produce a range of products to meet dynamic market demands. Manufacturing the solutions under the same roof they are developed minimizes the chances of variations and errors.

The inability of enzymes to detect liposome has endeared it to drug manufacturers. It has responded well on specificity and meets the expectations by developers. This is a dependable element in reducing body toxicity through specific target. This has been achieved through expert design and structuring.
