The cutaneous route is attractive for the delivery of drugs in the treatment of a wide variety of diseases. However the stratum corneum (SC) is an effective barrier that hampers skin penetration. Within this context, liposomes emerge as a potential carrier for improving topical delivery of therapeutic agents. In this review, we aimed to discuss key aspects for the topical delivery by drug-loaded liposomes. Phospholipid type and phase transition temperature have been shown to affect liposomal topical delivery...

The high performance liquid chromatography (HPLC) was used for quantitative determination of phenylethyl resorcinol (PR) which was loaded in the novel vesicle carriers including ethosome, invasome and transfersome formulations, and permeated into pig skin membrane and receptor fluid for skin permeation study. The reverse-phase chromatography was carried out with a C18 column (150 × 4.6 mm2, 5 μm, HypersilTM, Thermo Fisher Scientific Inc, USA) with the column temperature at 25°C. A mixture of acetonitrile-methanol-Milli-Q water in the ratio of 40:20:40%, v/v/v was used as a mobile phase by maintaining the flow rate at 0...

Surfactants generally have been used as edge activators of transfersomes. However, surfactants edge activated transfersomes frequently lead to cutaneous irritation, skin lipid loss and other side effects after dermal administration. In this study, mixed monoterpenes edge activated PEGylated transfersomes (MMPTs) were prepared by ethanol injection process with sinomenine hydrochloride as a model drug. The formulation of MMPTs was optimized by an orthogonal design. We investigated skin permeation/deposition characteristics and pharmacokinetics of sinomenine hydrochloride loaded in MMPTs by comparing with liposomes using in vitro skin tests and in vivo cutaneous microdialysis...

The aim of study was to design, statistically optimize and characterize Granisetron HCl loaded transfersomal gel for transdermal delivery, in order to overcome the side effects associated with oral delivery. A response surface methodology experimental design was applied for the optimization of transfersomes, using Box-Behnken experimental design. Phospholipid-90G, sodium deoxycholate and sonication time, each at three levels, were selected as independent variables, and while entrapment efficiency, vesicle size and transdermal flux were identified as dependent variables...

The emergence of drug resistance has rekindled interest in phage therapy as an alternative treatment option; its potency, safety, and proven efficacy are worth noting. However, phage therapy still suffers from issues of poor stability, narrow spectra, and poor pharmacokinetic profiles. Therefore, it is essential to look into the use of drug delivery systems for efficient delivery of lytic phages in vivo The present study evaluated the use of nanostructured lipid-based carriers, i.e., transfersomes, as transdermal delivery systems for encapsulating a methicillin-resistant Staphylococcus aureus (MRSA) phage cocktail...

This study was aimed to evaluate the in vitro transdermal direct/pulsed current iontophoretic delivery of an amphiphilic model compound from various lipid vesicle-encapsulated formulations compared to free-drug formulation. Conventional, pegylated, ultradeformable liposomes (transfersomes) and ethosomes loaded with a negatively charged drug diclofenac sodium (DS) were prepared and characterized. All the liposomes possessed an average size of ≈100-150nm and negative zeta potential. No changes in colloidal stability were detected after 8h incubation of any vesicle formulation under constant or pulsed iontophoretic current...

Loratadine (LTD) is an antihistaminic drug that suffers limited solubility, poor oral bioavailability (owing to extensive first-pass metabolism), and highly variable oral absorption. This study was undertaken to develop and statistically optimize transfersomal gel for transbuccal delivery of LTD. Transfersomes bearing LTD were prepared by conventional thin film hydration method and optimized using sequential Quality-by-Design approach that involved Placket-Burman design for screening followed by constrained simplex-centroid design for optimization of a Tween-80/Span-60/Span-80 mixture...

Timolol Maleate (TiM), a nonselective β-adrenergic blocker, is a potent highly effective agent for management of hypertension. The drug suffers from poor oral bioavailability (50%) due to its first pass effect and a short elimination half-life of 4 h; resulting in its frequent administration. Transdermal formulation may circumvent these problems in the form of protransfersomes. The aim of this study is to develop and optimize transdermal protransfersomal system of Timolol Maleate by film deposition on carrier method where protransfersomes were converted to transfersomes upon skin hydration following transdermal application under occlusive conditions...

BACKGROUND: Psoriasis is a chronic autoimmune inflammatory skin disease affecting 2 to 3% of people worldwide. Topical therapy as first option in the management of psoriasis is an attractive strategy by delivering drugs efficiently into target sites of disease, minimizing systemic side effects of drugs and ensuring high patient compliance. However, the delivery of antipsoriatic agents via conventional topical formulations is limited due to their poor percutaneous penetration and targeting into deeper layers of the skin...

Paeonol shows effective anti-allergic, anti-inflammatory and analgesic activities. However, because of its poor solubility in water and high volatility at room temperature, the application of this drug is restricted in the clinic. The objective of this research was to develop a biocompatible paeonol formulation with improved stability, skin delivery and pharmacokinetic efficiency. In this paper, paeonol-loaded vesicles were prepared using an ethanol injection method. Nano-vesicles were characterized for their physical properties and encapsulation efficiency (EE)...

Acne vulgaris is a common skin problem affecting nearly 90% of adolescents and its development is associated with a colonization of Propionibacterium acnes (P. acnes). Although antibiotics have commonly been used to treat acne, antibiotic resistance of P. acnes is an emerging issue to be solved. In this study, a new way of photodynamic acne therapy is developed using P. acnes lipase-sensitive transfersome (DSPE-PEG-Pheo A (DPP) transfersome). For enhanced selectivity and skin penetration efficiency, DPP transfersomes are prepared from 1,2-distearoyl-sn-glycero-3-phosphoethanolamine-N-[amino(polyethylene glycol)-2000], pheophorbide A (Pheo A), cholesterol, and Tween-80...

The drug suffers from extensive first pass effect, resulting in a reduction of oral bioavailability (F%) to 50% and a short elimination half-life of 4 h; parameters necessitating its frequent administration. The current study was therefore, designed to formulate and optimize the transfersomal TiM gel for transdermal delivery. TiM loaded transfersomal gel was optimized using two 2(3) full factorial designs; where the effects of egg phosphatidyl choline (PC): surfactant (SAA) molar ratio, solvent volumetric ratio, and the drug amount were evaluated...
