This item covers developments relevant to cannabis medicine and clinical practice. Clinicians monitoring evidence in this area should review the source material.
Chronic wounds are a leading healthcare burden worldwide, fueled by intricate pathophysiology and the inadequacy of standard therapies. The present review critically discusses the novel paradigm of incorporating cannabidiol (CBD), a phytocannabinoid with significant anti-inflammatory, antioxidant, antimicrobial, and pro-regenerative capacities, into advanced smart hydrogel platforms for better wound healing and tissue regeneration. We summarize the strong rationale for CBD, focusing on its multimodal pharmacological effects on central pathways (e.g., proinflammatory cytokines, oxidative stress, fibroblast activity, angiogenesis, endocannabinoid system) and reconciling its inherent delivery issues (poor solubility, instability, pharmacokinetics). The review comprehensively addresses the engineering of stimulus-responsive hydrogels (pH-, temperature-, enzyme-, redox-sensitive) to surmount these challenges. Material properties of key interest-biocompatibility, biodegradation tuneability,
“This is a development worth tracking. The clinical implications will become clearer as more evidence accumulates.”

FAQ
What are CBD-loaded smart hydrogels meant to do?
They combine cannabidiol (CBD) with advanced smart hydrogel platforms to improve wound healing and tissue regeneration. The article summarizes a review that critically discusses this novel approach, including the rationale for using CBD in chronic wounds and the engineering of hydrogels that can carry it.
Why is CBD being studied for chronic wound healing?
The review describes CBD as having anti-inflammatory, antioxidant, antimicrobial and pro-regenerative capacities. Its rationale centers on CBD’s effects on several pathways, including proinflammatory cytokines, oxidative stress, fibroblast activity, angiogenesis and the endocannabinoid system. Chronic wounds are described as a leading healthcare burden, with standard therapies often inadequate.
What makes CBD difficult to deliver to a wound?
CBD has inherent delivery issues, including poor solubility, instability and pharmacokinetic limitations. The review discusses how smart hydrogels can be engineered to surmount these challenges, and it considers this pairing a novel paradigm for wound healing and tissue regeneration.
What kinds of smart hydrogels are discussed for delivering CBD?
The review addresses the engineering of stimulus-responsive hydrogels, which are designed to be sensitive to pH, temperature, enzymes or redox conditions. It also highlights material properties of key interest for these platforms, including biocompatibility and the ability to tune how the hydrogel biodegrades.
