Enhancing 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.

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.

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.

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 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.
