Intercalation and controlled release of pharmaceutically active compounds from a layered double hydroxide

Area of Science:

• Materials Science
• Pharmaceutical Science
• Nanotechnology

Background:

• Layered double hydroxides (LDHs) are recognized for their anion exchange capabilities.
• Drug delivery systems aim for controlled and targeted release of active pharmaceutical ingredients.
• Intercalation into nanomaterials offers a promising route for drug stabilization and delivery.

Purpose of the Study:

• To investigate the intercalation of various pharmaceutically active compounds into layered double hydroxides.
• To evaluate the potential of these intercalated materials as a novel drug delivery system.
• To explore the tuneability of drug loading and release characteristics.

Main Methods:

• Synthesis of layered double hydroxide materials.
• Reversible intercalation of model pharmaceutical compounds (e.g., diclofenac, ibuprofen, naproxen).
• Characterization of intercalated compounds using techniques like X-ray diffraction and spectroscopy.

Main Results:

• Successful reversible intercalation of multiple pharmaceutical compounds into the LDH structure was achieved.
• Evidence suggests the formation of a stable drug-LDH composite.
• Initial studies indicate the potential for controlled release applications.

Conclusions:

• Layered double hydroxides can serve as effective hosts for a range of pharmaceutical agents.
• The developed intercalation method offers a foundation for a novel, tuneable drug delivery platform.
• Further research is warranted to optimize drug loading and release kinetics for therapeutic applications.
