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.

There is an effect when one considers the sizes of liposomes required to deliver the drugs. This translates into reliable efficacy considering that circulation in the blood and residence are enhanced. Target drugs are easily absorbed by body organs and their efficacy enhanced. This has a bearing on the effectiveness of the drug. Getting a specific size is the current focus in most of the studies to boost effectiveness.

Experts in solution formulation use their experience to develop tailor-made solutions depending on individual demands. It takes experience and expertise to generate the liposomal and lipid solutions that make your work effective. They also will assist in optimizing the existing solution using solvents and surfactants.

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.

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 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.

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.
