Semi-Solid and Solid Dosage Forms for the Delivery of Phage Therapy to Epithelia

Area of Science:

• Microbiology
• Pharmaceutical Sciences
• Biotechnology

Background:

• Bacteriophage therapy is a promising alternative to antibiotics for treating bacterial infections.
• Delivery of phages to epithelial surfaces is crucial for effective therapeutic outcomes.
• Current research is exploring various dosage forms for topical phage delivery.

Purpose of the Study:

• To review existing research on phage formulations for epithelial delivery.
• To discuss the efficacy and stability of different phage dosage forms.
• To highlight the importance of standardized formulation and efficacy assessment techniques.

Main Methods:

• Literature review of studies on phage formulation in semi-solid (creams, ointments, pastes) and solid (troches, suppositories) dosage forms.
• Analysis of factors influencing phage efficacy and stability within these formulations.
• Identification of challenges and needs for standardization in phage formulation and assessment.

Main Results:

• Phages can be formulated into various semi-solid and solid dosage forms for epithelial delivery.
• Selection of optimal semi-solid bases is critical for maintaining phage efficacy and stability.
• Standardization of formulation and efficacy assessment methods is needed for comparable results.

Conclusions:

• Formulating phages into appropriate dosage forms is a viable strategy for epithelial delivery.
• Further research and standardization are necessary to optimize phage therapy efficacy and facilitate clinical translation.
• Consistent methodologies are essential for comparing phage formulation effectiveness across different bases and studies.
