It has been claimed by Idea AG that intact Transfersomes penetrate through the stratum corneum and the underlying viable skin into the blood circulation. The steady-state flux was determined as the slope of linear portion of the plot. In preparing MX-loaded liposomes and transfersomes, the materials were deposited in a test tube, and the solvent was evaporated with nitrogen gas.

To study the release kinetics, data obtained from in vitro permeation studies were fitted in various kinetic models: Formulation of sertraline transfersomes The transfersomes were formulated by the conventional rotary evaporation sonication method [ 78 ].

Transfersome

All formulations were tranefersomes to be in the nano size range with low values of polydispersity index. The probable reason for the high permeation of the transfersomal gel formulations may be the partitioning of vesicles into the stratum corneum, which is an important process as it drives the partitioning of vesicle-bound drug into the skin.

The institutional and international guide for the care and use of laboratory animals was followed. Meloxicam MX was supplied from Fluka. The first group served as the control group, i. The maximum entrapment efficiency obtained was In vitro and in vivo transfection efficiency of a novel ultra deformable cationic polymer.

The results of the present study indicate that the transfersomal gel formulated by using span 80, soya lecithin, and carbopol EL-SP4 can be used to enhance skin delivery of sertraline because of excellent release and permeation of the drug. Liposomes are promising carriers for enhancing skin permeation because they have high membrane fluidity. The drug concentration in the resulting solution was assayed by a UV spectrophotometer Shimadzu-Japan at nm [ 9 ]. Entrapment efficiency was found to first increase with the increase of the drug while no crystal appeared upon addition of 0.

Lag time was also obtained by extrapolating transfresomes linear portion of the penetration profile to the abscissa.

Recommended articles Citing articles 0. Morphology and Structure of transfersomes The morphology and structure of the drug-loaded transfersomes were determined with the aid of Transmission Electron Microscopy TEM: This transfersomal gel formulation increased the struggling behavior of mice by decreasing the time of immobility or depression.

It is primarily due to the remarkable strong membrane adaptability that allows the transfersomal vesicles to lodge in a confining pore, and thus permeate that pore [ 356 ]. Hair on the dorsal skin of the sacrificed animal was removed with an animal hair clipper, subcutaneous tissue transfersoomes surgically removed, and the dermis side was wiped with isopropyl alcohol to remove residual adhering fat.

As the concentration in the external phase increased, the network formed between the surfactant molecules, micelles, and vesicles. De La Maza, J.

A thin film of transfersomes was spread on a slide and a cover slip was placed over it and then observed under the optical microscope [ 10 ]. Rransfersomes Subcutaneous Transdermal implant. According to Ammar et al.

At time intervals of 0. Supplemental Content Full text links. Span 80 was selected as the edge activator surfactant for the transfersomal formulation as it is biocompatible and pharmaceutically acceptable [ 17 ]. Find articles by Ritika Arora. Footnotes This article is available from: The physical particle size determination and chemical percent MX remaining in the formulation stability of the vesicles are presented in Table 3 and Figure 4respectively.

The forced swim model test showed that the transfersomal gel formulation has better antidepressant activity because of the increased struggling behaviour of mice and the decreased time of immobility. By addition of at least one bilayer softening component such as a biocompatible surfactant or an amphiphile drug lipid bilayer flexibility and permeability are greatly increased. The MX concentration was varied from 2. The FT-IR spectrum of the untreated skin was also recorded and used as a control.

The cumulative amount of drug increased linearly with time after a short lag time 0. The consistency index of the transfersomal gel formulation EL-SP4 having high viscosity Sertraline, Transfersomes, Transdermal, Permeation studies, In vivo study.

In the present study, MX-loaded transfersomes were successfully prepared by a sonication method. The morphology and structure of the drug-loaded transfersomes were determined with the aid of Transmission Electron Microscopy TEM: Polydispersity index is the ratio of the standard deviation to the mean particle size and signifies the uniformity of particle size within the formulation. The surfactants used were anionic surfactants, and the anion form of MX was also the predominant form at pH 7.

Statistical analysis All of the studies were carried out in triplicates. Interpretation of release mechanism The formulation EL-SP4 was best fitted for the Higuchi kinetic equation as the formulation coefficient of correlation values predominates over zero-order and first-order kinetics Table 2.

The dorsal surface of the skin was placed in contact with the donor chamber, which was filled with the liposome formulation. They can also adsorb onto or fuse with the SC, and the intact vesicle can penetrate into and through the intact skin.

The entrapment efficiencies and the loading efficiencies of the MX-loaded formulation were calculated by 1 and 2respectively. Loading of the drug above this value gave less entrapment as well as crystals.
