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.

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.

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 reliable company will deliver good results depending on the track record and commitment to meet customer demands. Diversity of the compounds they are dealing with is an indication of capability and should be considered as well. All the solutions will be developed and manufactured within the same factory reducing the possibility of errors and variations.

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.
