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.

Incredible results have been obtained from testing liposomes over the years. They have shown a great deal of potential that scientists seek to utilize. Some of the admirable aspects with liposomes include enzyme resistance during metabolism, high solubility as well as specificity. Researchers are narrowing down on this element.

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.

Liposomal sizes matter and have an effect on how effective the drug will be. They determine the efficacy of drugs, duration of residency in the body and circulation as well. This property makes target drugs easy to deliver and absorb in the body increasing efficacy. This makes the drug more effective. The right size depends on the project at hand and determines the level of success in achieving effectiveness.

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.

Other scalable processes include injection of solvents, dispersion or lipid hydration, lyophilization and related aseptic processes. Liposomal analysis is carried out to establish distribution and sizes of the particles. Other analysis procedures are morphology or electron microscopy, encapsulation efficiency tests and determination of zeta potential. Other procedures carried out include drug loading.

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.

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.
