Transfersomes: self-optimizing carriers for bioactives.

Area of Science:

• Pharmaceutical Sciences
• Biotechnology
• Dermatology

Background:

• Transdermal drug delivery bypasses oral administration issues but faces the stratum corneum barrier.
• Hydrophilic, ionizable bioactives struggle with skin diffusion due to this barrier.
• Various strategies exist to enhance transdermal delivery, including physical and chemical methods.

Purpose of the Study:

• To review the potential of transfersomes as a vesicular system for effective transdermal drug delivery.
• To highlight the advantages and applications of transfersomes in delivering diverse bioactive molecules across the skin.

Main Methods:

• Review of existing literature on transdermal drug delivery strategies.
• Focus on vesicular systems, particularly transfersomes, and their skin penetration mechanisms.
• Analysis of factors influencing transfersome flexibility and efficacy.

Main Results:

• Transfersomes demonstrate significant potential for enhancing transdermal delivery due to their flexible membrane structure.
• Their efficacy is demonstrated for delivering drugs, vaccines, steroids, proteins, peptides, and genetic material.
• The appropriate surfactant ratio is crucial for achieving the necessary membrane flexibility for skin transport.

Conclusions:

• Transfersomes represent a promising strategy for overcoming skin barriers in transdermal drug delivery.
• Their versatility makes them suitable for a wide range of therapeutic agents and applications.
• Further research into transfersomes can optimize drug delivery and therapeutic outcomes.
