Silica-based mesoporous materials as drug delivery system for methotrexate release

Area of Science:

• Materials Science
• Nanotechnology
• Pharmaceutical Sciences

Background:

• Mesoporous silica materials offer tunable properties for drug delivery.
• Antineoplastic drugs like methotrexate require effective delivery systems for oral administration.
• Controlling pore size is crucial for optimizing drug loading and release.

Purpose of the Study:

• To synthesize and characterize mesoporous alumina-silica materials.
• To investigate the loading and in vitro release of methotrexate using these materials.
• To establish the relationship between material pore size and drug delivery performance.

Main Methods:

• Self-assembly synthesis of mesoporous materials using cationic surfactants with varying alkyl chain lengths (C16, C12, C10).
• Preparation of pure silica and alumina-silica samples.
• Drug loading of methotrexate via soaking procedures.
• In vitro release studies mimicking oral administration.

Main Results:

• Alumina-silica mesoporous materials successfully loaded methotrexate, unlike pure silica.
• Drug loading capacity and in vitro release kinetics were significantly influenced by the pore diameter of the materials.
• The pore size directly correlated with the amount of drug loaded and its release profile.

Conclusions:

• Mesoporous alumina-silica materials are promising carriers for antineoplastic drug delivery.
• Tailoring pore size through controlled synthesis is essential for optimizing methotrexate loading and release kinetics.
• These materials demonstrate potential for developing effective oral drug delivery systems.
