Liposomes, tiny bubbles made from the same material as a cell membrane, are considered the most successful nanocarriers for drug delivery. They are biocompatible and stable, encapsulating both hydrophilic and lipophilic drugs and protecting them from degradation. Liposomes are the most commonly used drug delivery vehicles due to their high drug trapping capacity and efficiency. These offer controlled release, targeted drug delivery, increased therapeutic efficacy, and reduced dosing frequency. Liposome-based drug formulations have been approved for clinical use and are the subject of extensive research. Recent liposomal formulations aim to reduce toxicity and increase target site accumulation. With numerous advantages, liposomes prove their uniqueness in safe drug delivery in various areas of pharmacy and medicine. We will keep an eye on overall updated review on liposomes classification, their structural components, mechanism of action, stability, method of preparation, their evaluation tests and applications.
