In recent years, great achievements have been made in the development of drug delivery systems, which bring potential therapeutics for diverse diseases. Many disease treatments remain to have some side effects despite all of the progress, which limits scientists' ability to treat many diseases such as cancer, neurodegenerative diseases, and infectious diseases. However, it is surprising that researchers do not give up but devote much effort to this field. Therefore, it is hopeful that sustained progress in this area will facilitate the targeted delivery of drugs while also mitigating their side effects.
Among various drug delivery methods, vesicular system-based drug delivery is considered the most effective delivery method. In recent years, vesicles have become crucial carriers of drug delivery systems because they provide a practical approach for delivering drugs directly to the infection, reducing drug toxicity, and ensuring no adverse effects, including liposome-based drug delivery and ultrasome-based drug delivery.
Because the liposomes are highly biocompatible and easy to control in vivo, liposome-based drug delivery possesses many advantages, including non-toxicity, being biocompatible and completely biodegradable, increasing drug efficacy, increasing stability, reducing the toxicity of drugs, and providing flexibility for active targeting. Following that, liposome products are in increasing demand on the market, such as the clodronate liposome, fluorescent liposome, liposomal doxorubicin, immunoliposomes, plain liposome, and cationic liposome.
In addition, virosomes, as the novel strategy for drug delivery and targeting, are defined as one of the optimal drug delivery systems because they are biocompatible, biodegradable, non-toxic, and non-autoimmunogenic. And attempts have been made to use them as vaccines or adjuvants as well as delivery systems for drugs, nucleic acids, or genes for therapeutic purposes. Virosome-based drug delivery methods have the potential to address issues that have arisen in other promising drug developments, such as the inability to successfully deliver drugs to target cells. At present, virosomes represent an innovative drug carrier system that has been applied broadly in diverse treatments and prevention of cancer, neurological disorders, and infectious diseases.
Liposomal formulations have a key role in the development of liposome drug delivery compared to general formulations, which can be utilized to overcome the non-ideal properties of drugs, including limited solubility, serum stability, circulation half-life, biodistribution, and target tissue selectivity. Liposome formulations have advantages in a variety of disease fields, including tumors, infections, neurology, anesthesia, ophthalmology, and diagnosis. Liposome-encapsulated drugs have 50%–70% lower tumor toxicity than free drugs, and liposome formulations have higher tumor suppressor activity than free drugs.
Furthermore, functional liposome development is as important as the development of liposomal formulations. Liposomes can be used for specific applications by using appropriate surface functionalization and modification technology, such as extending circulation time, increasing cellular uptake, and increasing tumor site payload accumulation, for which the functional liposome provides key benefits in disease treatment. The growing demand for functional liposomes drives the continuous and rapid development of global biotechnology, and biotech companies all over the world are engaged in fierce competition to capture the abundant market share.
