Enhancing Drug Delivery Through Liposome

By Irma Farrell


Scientists have been working on improving drug delivery to different parts of the body. Delivery vehicles used in this case have different structures and design. The search for a mechanism to deliver the drugs to a specific area has favored the use liposome. The features that scientists are looking for include specificity with receptors, higher payload, stealth mode operation to enhance its circulatory lifetime, less harmful side effects, efficacy and better uptake.

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.

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.

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 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.

Liposome is preferred because it is able to withstand enzymes in the body and responds well when required to attend to specific areas. Developers are trying to master these properties. It has proven effective in administering lower dosages thus reducing toxicity. The structure and design are admirable.
