Abstract
Treatment of skin ailments through systemic administration is limited due to toxicity and
patients discomfort. Hence, lower risk of systemic side effects from topical dosage forms like ointments,
creams, emulsions and gels is more preferred for the treatment of skin disease. Application
of lipid based carriers in drug delivery in topical formulations has recently become one of the major
approaches to improve drug permeation, safety, and effectiveness. These delivery systems include
liposomes, ethosomes, transfersomes, Nanoemulsions (NEs), Solid Lipid Nanoparticles (SLNs)
Nanostructured Lipid Carriers (NLCs) and micelles. Most of the liposomes and SLNs based products
are in the market while some are under investigation. Transcutaneous delivery of therapeutics
to the skin layer by novel lipid based carriers has enhanced topical therapy for the treatment of skin
ailments. This article covers an overview of the lipid-based carriers for topical uses to alleviate skin
diseases.

Matos C, Lobão P. Non-Steroidal Anti-Inflammatory Drugs Loaded Liposomes for Topical Treatment of Inflammatory and Degenerative Conditions. Curr Med Chem 2020; 27:3809-3829. [DOI: 10.2174/0929867326666190227233321] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/12/2018] [Revised: 12/27/2018] [Accepted: 02/15/2019] [Indexed: 12/18/2022]
Abstract
Topical administration of drugs presents some advantages over other routes; the drug can be
administered in the anatomical region to be treated, limiting the systemic distribution and side effects.
However, the structure of the skin makes it a highly effective barrier to drug permeation. Amongst the
strategies to overcome this obstacle, liposomes are interesting vehicles for delivering the drugs into the
skin, the synovial cavity or other regions affected by inflammatory or degenerative conditions.
Liposomes are lipid carriers of nanometric size formed by phospholipid bilayers. They have the advantages
of preparation feasibility and biological compatibility associated with the possibility of carrying
either lipophylic and/or hydrophylic compounds, and have been extensively used in various drug delivery
systems, for drug targeting, controlled release and permeation enhancement of drugs. Conventional
liposomes are not very stable and not suitable for dermal administration after topical application, since
they accumulate on the skin surface due to the rigidity of the lipid layers and suffer dehydration, culminating
in their fragmentation. Other formulations have emerged in the meantime, such as transfersomes,
niosomes or ethosomes. The present work consists of a review on the published scientific papers regarding
the development of liposomal formulations containing non-steroidal anti-inflammatory drugs for the
purpose of relieving the symptomatology of inflammatory and degenerative ailments. The exposition
summarizes data relating to liposome type, composition, preparation method, liposome characterization,
topical vehicle used, in vitro permeation studies performed, in vivo anti-inflammatory assays carried out
and results obtained in the different studies published in the last five years.

Abstract
New generation of amphiphilic vesicles known as aspasomes were investigated as potential carriers for transdermal delivery of tizanidine (TZN). Using full factorial design, an optimal formulation was developed by evaluating the effects of selected variables on the properties of the vesicles with regards to entrapment efficiency, vesicle size and cumulative percentage released. The optimal formula (TZN-AS 6) consisting of 20 mg TZN, 50 mg ascorbyl palmitate (AP), 50 mg cholesterol (CH) and 50 mg Span 60, represented well dispersed spherical vesicles in the nanorange sizes and exhibited excellent stability under different storage conditions. Ex-vivo permeation studies using excised rat skin showed a 4.4-fold increase of the steady state flux in comparison to the unformulated drug (p < 0.05). The pharmacokinetic parameters obtained from the in-vivo study using Wistar rats, showed that the bioavailability of TZN was enhanced significantly (p < 0.05) when compared to the oral market product of TZN, Sirdalud®. Moreover, skin irritancy tests confirmed that the vesicles were non-invasive and safe for the skin. Based on the results obtained, the optimised aspasomes formula represents a promising Nano platform for TZN to be administered transdermally, thus improving the therapeutic efficacy of this important muscle relaxant.

Planar lipid bilayers formed from thermodynamically-optimized liposomes as new featured carriers for drug delivery systems through human skin. Int J Pharm 2019; 563:1-8. [PMID: 30926525 DOI: 10.1016/j.ijpharm.2019.03.052] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/17/2018] [Revised: 03/09/2019] [Accepted: 03/25/2019] [Indexed: 10/27/2022]
Abstract
The fundamental objective pursued in this work is to investigate how liposomes formed with a thermodynamically optimized molar composition formed by the main components of the stratum corneum matrix behave on the human skin surface when used as drug delivery systems. To this purpose we engineered liposomes using phosphatidylcholines, ceramides and cholesterol. The specific molar ratio of the three components was established after studying the mixing properties of the lipid monolayers of the lipid components formed at the air-water interface. Liposomes loaded and unloaded with ibuprofen and hyaluronic acid were characterized by quasi-elastic light scattering and fluorescence polarization. Optimized liposomes, with and without drugs, were applied onto human skin and the structures formed evaluated using atomic force microscopy. Since penetration enhancers improve the permeation of the drugs encapsulated, we also examined the effects of Tween® 80 on the physical properties of the liposomes and on their extensibility over skin. In the present work we were able to observe the deposition and extension of liposomes in suspension onto human skin demonstrating the potential of liposomes without a secondary vehicle for releasing drugs in transdermal applications.

Abstract
Abstract
The objective of the present study was to develop and characterize nano-ethanolic liposomes (NEL) for transdermal delivery of ibuprofen (IBU). The NEL for transdermal delivery of IBU were prepared by thin film hydration technique and evaluated for vesicle size, shape, entrapment efficiency, transdermal flux, and in vivo anti-inflammatory activity in Wistar rats. The NEL optimized formulation (NEL-Opt) presented vesicle sizes of 32.85±1.98 nm and entrapment efficiency of 86.40±0.55% with improved transdermal flux. The presence of ethanol and flexibility of NEL could be the reasons for better permeation enhancement of IBU via rat’s skin. In vivo anti-inflammatory study of IBU-loaded NEL-Opt gel showed significant reduction (41.18%) of edema in carrageenan-induced rat paw edema as compared to conventional gel of IBU, where reduction of edema was found to be 12.50%. Our results suggest that developed NEL formulations are efficient systems for transdermal IBU delivery against inflammation. The stability study confirmed that the NEL-Opt gel formulation was considerably stable at refrigerator temperature. Our results concluded that NEL are an efficient carrier for transdermal delivery of IBU.
