World Stroke Day: Evaluation of Animal Drug Efficacy Models for the Development of Cardiovascular and Cerebrovascular Drugs

 

• October 29, 2022

October 29th, 2022, is the seventeenth “World Stroke Day.” “World Stroke Day” was established by the World Stroke Organization (World Stroke Organization) to call for strengthening public awareness of stroke globally.

Stroke is the scientific name of cerebralvascular accident, which generally refers to ischemic or hemorrhagic diseases of the heart, brain and tissues of the whole province caused by hyperlipidemia, blood clotting, atherosclerosis, hypertension, etc. It is a sudden onset of cerebral blood circulation disorders. The clinical manifestations are mainly characterized by sudden dizziness, unconsciousness, or sudden deviated eyes, hemiplegia, and intellectual disability. Stroke mainly includes ischemic stroke (transient ischemic attack, atherosclerotic thrombotic cerebral infarction, lacunar cerebral infarction, cerebral embolism) and hemorrhagic stroke (cerebral hemorrhage, subarachnoid hemorrhage).

Stroke is known as “the number one killer of human health” because of its high prevalence, high morbidity, high mortality and high disability rate. In China, the annual treatment cost of cardiovascular and cerebrovascular diseases is 540.6 billion yuan. The annual treatment cost of cerebrovascular diseases accounts for 25.68% of cardiovascular and cerebrovascular diseases. Among them, ischemic stroke accounts for 18% and hemorrhagic stroke accounts for 7%.

Although the annual treatment cost of stroke is so high, there is still a problem that there are few drugs for clinical specific treatment, and there is a huge gap in the demand for clinical drugs. Therefore, the market potential of stroke drugs is great and the development prospect is good.

For the preclinical development of stroke drugs, the two mountains of pharmacokinetics and pharmacodynamics cannot be avoided, and the models used in both pharmacokinetics and pharmacodynamics are particularly important.

Summary and Outlook

In recent years, with the continuous development of biomedical technology, more and more stroke drugs have gone from the target to the stage of preclinical testing. We believe the problem will be solved soon！
