What exactly is meant by the term “liposomes in drug delivery”?

Liposomes are vehicles for successfully carrying chemicals into the body, either by aiding absorption directly in the mouth or by avoiding breakdown by stomach acid. Liposomes in a drug delivery may perform any of these functions.

What kind of product is a liposome?

Liposomes are often used to encapsulate the active pharmaceutical ingredient in a liposome-based pharmaceutical product. Generally speaking, medications that are water soluble are stored in the aqueous compartment(s) of the liposomes, while pharmaceuticals that are hydrophobic are stored in the lipid bilayer(s) of the liposomes.

What role do liposomes play in drug delivery?

Liposomes in the delivery of a drug have better properties than traditional systems, including site-targeting, protection of drugs from degradation and clearance,  and lower toxic side effects.

What are the primary benefits of using liposomes in drug delivery?

Liposomes are capable of forming complexes with molecules that are either positively or negatively charged. The DNA is afforded some measure of protection from the processes that lead to its degradation by the presence of liposomes. There is some evidence that liposomes are capable of transporting DNA fragments as large as chromosomes. It is possible for liposomes to be directed to specific cells or organs.

What kinds of medications may be transported inside a liposome?

Due to the many different shapes that liposomes may take, these structures are able to transport hydrophilic and hydrophobic medications, making them useful in the treatment of cancer as well as infections caused by bacteria, fungi, and viruses, immunomodulation, diagnostics; ophthalmology; vaccines; enzymes; and genetic elements.

How do liposomes carry out their roles in the body?

A hydrophilic solute that is dissolved in the core of a liposome is unable to easily pass through the lipid bilayer because the core of a liposome is an aqueous solution that is surrounded by a hydrophobic barrier in the form of a lipid bilayer. Because of this, Liposomes in the delivery of a drug are capable of being loaded with molecules that are either hydrophobic or hydrophilic.

Can liposomes transport DNA?

It is common practice to use liposomes when trying to transport a molecular payload such as DNA for medicinal purposes. These lipoplexes may be formed using cationic lipids, anionic lipids, neutral lipids, or a combination of all three types of lipids.

Final Thoughts

Liposomes are spherical vesicles that are made up of one or more concentric phospholipid bilayers that enclose an aqueous core. These vesicles are known as liposomes. Liposomes are an effective delivery mechanism for a number of different drugs since they are both safe to use and biodegradable.
