Toward Carbon Monoxide-Based Therapeutics: Critical Drug Delivery and Developability Issues

Area of Science:

• Pharmacology
• Drug Delivery
• Biochemistry

Background:

• Carbon monoxide (CO) is an intrinsic signaling molecule, comparable in importance to nitric oxide.
• Extensive pharmacologic studies over the last decade highlight the therapeutic potential of CO.
• Current CO therapeutic strategies primarily rely on CO inhalation or metal-based CO-releasing molecules.

Purpose of the Study:

• To review the current state of pharmaceutical development for carbon monoxide.
• To identify and discuss existing challenges in CO drug delivery.
• To propose strategies for overcoming hurdles in developing pharmaceutically acceptable CO formulations.

Main Methods:

• Review of existing literature on carbon monoxide pharmacology and therapeutics.
• Analysis of current CO-releasing molecule (CORM) technologies and delivery routes.
• Discussion of developmental strategies for oral, injectable, infusible, and topical CO formulations.

Main Results:

• Significant therapeutic potential of carbon monoxide has been demonstrated.
• Existing CO delivery methods (inhalation, CORMs) have limitations for widespread pharmaceutical use.
• There is a critical need for diverse, pharmaceutically acceptable CO delivery systems.

Conclusions:

• The field requires a concerted effort to develop novel CO drug delivery platforms.
• Addressing drug delivery challenges is essential for realizing the full therapeutic potential of CO.
• Future research should focus on creating versatile CO formulations for various administration routes.
