Fighting type 2 diabetes: Formulation strategies for peptide-based therapeutics

Area of Science:

• Endocrinology and Metabolism
• Pharmacology
• Drug Delivery Systems

Background:

• Diabetes mellitus is a growing global health concern.
• Glucagon-like peptide-1 receptor agonists (GLP-1 RAs) are crucial in diabetes management.
• Subcutaneous administration is preferred for biotherapeutics like GLP-1 RAs due to patient compliance.

Purpose of the Study:

• To review challenges associated with subcutaneous administration of peptide-based therapeutics.
• To provide an overview of advanced formulations for GLP-1 RAs.
• To highlight strategies for improved bioavailability and reduced dosing frequency.

Main Methods:

• Literature review of current subcutaneous formulations for GLP-1 RAs.
• Analysis of pharmacokinetic challenges and adverse reactions.
• Exploration of alternative delivery routes and formulation technologies.

Main Results:

• Current subcutaneous GLP-1 RA formulations can cause pharmacokinetic issues, leading to adverse events and treatment discontinuation.
• Various advanced formulation strategies are being developed to overcome these limitations.
• Improved formulations aim to enhance drug absorption and extend duration of action.

Conclusions:

• Addressing pharmacokinetic challenges in subcutaneous GLP-1 RA delivery is critical for effective diabetes treatment.
• Novel formulations offer potential for improved patient compliance and therapeutic efficacy.
• Further research into optimized delivery systems will advance diabetes care.
