Advances in clinical studies of peptide drugs in stroke disease.

Stroke remains a leading cause of death and disability globally, with limited treatment options currently available. Fortunately, peptide drugs have emerged as promising candidates for treating central nervous system disorders, including stroke. They offer high specificity, low toxicity, and efficient blood-brain barrier penetration, demonstrating significant therapeutic potential. This review systematically introduces several promising peptide drugs, analyzing their mechanisms, therapeutic efficacy in clinical trials, and potential applications. It also addresses critical challenges in peptide drug development for stroke therapy, such as optimizing dosing strategies, enhancing stability, and improving delivery systems. The analysis of current clinical evidence suggests that peptide-based therapeutics represent a promising frontier in stroke treatment, potentially offering new therapeutic options for patients. This comprehensive review not only highlights the current status of peptide drug development but also provides insights into future directions for advancing stroke therapy.
