Paclitaxel Drug Delivery Systems: Focus on Nanocrystals' Surface Modifications

Area of Science:

• Pharmaceutical Sciences
• Materials Science
• Oncology

Background:

• Paclitaxel (PTX) is a vital chemotherapeutic agent from the taxane family, approved for treating various cancers.
• PTX exhibits poor water solubility, limiting its therapeutic applications and necessitating advanced delivery systems.
• Existing delivery systems include liposomes, nanoparticles, micelles, and cyclodextrin complexes.

Purpose of the Study:

• To provide a comprehensive review of paclitaxel nanocrystal (PTX NC) formulations.
• To explore various administration routes and modification strategies for PTX NCs.
• To summarize the advantages of PTX NCs in improving drug delivery and therapeutic outcomes.

Main Methods:

• Review of existing literature on paclitaxel nanocrystal formulations.
• Analysis of nano-crystallization techniques for PTX.
• Examination of formulation modifications, including surfactant stabilization and polymer coating.

Main Results:

• Paclitaxel nanocrystal formulations effectively enhance the solubility and pharmacological properties of PTX.
• Nano-crystallization enables diverse administration routes, including oral, intravenous (IV), intraperitoneal (IP), and local delivery.
• Modified PTX NCs demonstrate superior properties, improving drug delivery and potentially therapeutic efficacy.

Conclusions:

• Paclitaxel nanocrystals represent a promising strategy to overcome the limitations of conventional PTX formulations.
• Further research into modified PTX NCs can lead to improved cancer treatment outcomes.
• This review highlights the versatility and advantages of PTX NCs across different administration platforms.
