Liposomes: A Novel Drug Delivery System

Liposomes are microscopic vesicular structures composed mainly of
phospholipids and cholesterol that form bilayer membranes similar
to those found in biological cells. These vesicles are widely used as
carriers for drug delivery in pharmaceutical research because of their
ability to encapsulate both hydrophilic and lipophilic drugs.
Liposomes protect the incorporated drug molecules from degradation
and enhance their stability in biological environments. They also
improve the therapeutic efficiency of drugs by delivering them to
specific tissues or organs while minimizing harmful side effects. Due
to their biocompatibility, biodegradability, and versatility, liposomes
are considered an important component of modern drug delivery
systems. They can be administered through different routes,
including oral, topical, intravenous, nasal, ocular, and transdermal
routes. Liposomal formulations are widely used in the treatment of
cancer, infections, and other diseases. In addition, liposomes are
used in vaccine development, gene delivery, and cosmetic
formulations
