Solid surfactant solutions of active ingredients in sugar esters

Area of Science:

• Pharmaceutical Sciences
• Materials Science

Background:

• Poorly water-soluble drugs present challenges in oral drug delivery.
• Ciclosporin is an important immunosuppressant with limited water solubility.

Purpose of the Study:

• To prepare and characterize solid solutions of ciclosporin using sugar esters.
• To evaluate the potential of sugar esters as solubilizers for poorly water-soluble drugs.

Main Methods:

• Preparation of solid solutions of ciclosporin in sugar esters.
• Characterization of the solid solutions.
• Assessment of solubilization capacity.

Main Results:

• Sugar esters were identified as effective solubilizers for ciclosporin.
• The prepared solid solutions were biodegradable and nontoxic.
• Solid dosage forms for oral administration were feasible.

Conclusions:

• Sugar esters are excellent solubilizers for poorly water-soluble drugs like ciclosporin.
• Solid solutions in sugar esters offer a promising approach for oral drug delivery.
• The addition of water to these solid solutions readily yields clear drug solutions.
