In vitro study | Fasudil is a class of calcium antagonists. Fasudil competitively inhibits Ca Fasudil also has vasodilatory effects, by inhibiting the contraction of helical strips induced by serotonin, norepinephrine, histamine, angiotensin, and dopamine. Fasudil induces the disintegration of actin fibers and inhibits cell migration. Fasudil inhibits the proliferation of hepatic stellate cells, the formation of stress fibers, and the expression of α-SMA, and inhibits cell growth, but does not induce apoptosis. Fasudil inhibits LPA-induced ERK1/2, JNK and p38 MAPK phosphorylation. |
In vivo study | When Fasudil was administered at a dose of 30 μg by intracoronary injection to experimental dogs, the CBF increased by about 50%. Fasudil (0.01, 0.03, 0.1, and 0.3 mg/kg I. V.) decreased MBP and increased HR, VBF, CBF, RBF, and FBF in a dose-dependent manner. A total dose of 1.0 ng/mL of Fasudil increases cardiac output. Intravenous Fasudil treatment significantly reduced MBP, left ventricular systolic pressure, and total peripheral resistance, and increased HR and cardiac output, while right atrial pressure, there were no significant changes in dP/dt and work done by the left ventricle per minute. In the case of ischemic injury, Fasudil treatment has a protective effect on cardiovascular disease, and reduces the activation of JNK and inhibits mitochondrial AIF nuclear translocation. Daily oral administration of Fasudil at a dose of 100 mg/kg to SJL/J mice immunized with PLP p139-151 significantly reduced the incidence and the mean maximum value of EAE clinical score. Treatment of mice with Fasudil inhibits the proliferative response of splenocytes to antigen. Fasudil, administered orally to mice, reduces inflammation, and demyelination. |

overview | fasudil hydrochloride is a new drug with extensive pharmacological effects. it was first developed by Asahi Kasei Company of Japan and first listed in Japan in June 1995. In 2001, China approved the import of fasudil hydrochloride injection by Asahi Kasei Company of Japan under the trade name of "Yililu". Its molecular structure is 5-isoquinoline sulfonamide derivative, which is an RHO kinase inhibitor. It expands blood vessels by increasing the activity of myosin light chain phosphatase, reduces the tension of endothelial cells, improves brain microcirculation, does not produce and aggravate brain steal blood, and can antagonize anti-inflammatory factors, protect nerves against apoptosis, and promote nerve regeneration. Fasudil hydrochloride has a certain effect on promoting the recovery of nerve function, reducing clinical symptoms and reducing disability rate. Therefore, due to the constraints of economic conditions and the degree of understanding of the disease at the grassroots level, ultra-early thrombolytic therapy cannot be achieved, but in order to reduce the further progress of the disease, it is very important to rebuild the local blood circulation within the treatment time window. Fasudil hydrochloride has significant neuroprotective and therapeutic effects on ischemic cerebrovascular diseases. It is worthy of clinical use, especially at the grassroots level, to reduce the disability rate and improve the quality of life. |
Pharmacological effects | Fasudil hydrochloride is an isoquinoline sulfonamide derivative, which can not only inhibit the activity of free calcium ions in cells, but also inhibit protein kinase A.G.C and myoprotein light chain kinase, that is, inhibit smooth muscle contraction, the final stage of myosin light chain phosphorylation, make vascular smooth muscle relaxation, dilate blood vessels. In vitro experiments show that this product can relax the isolated cerebral blood vessels, inhibit the vasoconstriction caused by calcium ion influx, inhibit the contractile effect of various mechanisms of cerebrovascular constriction drugs, and inhibit intracellular calcium ions. The effect of vasoconstriction, but will not reduce the concentration of intracellular calcium ions, and inhibit the production of myosin light chain phosphorylates during vasoconstriction. It is clinically used to improve and prevent cerebral vasospasm and cerebral ischemia symptoms after subarachnoid hemorrhage. Intravenous administration of 30mg once, 2-3 times a day. This agent is applied in the early stage after subarachnoid hemorrhage, and it is generally appropriate to apply it for 2 weeks. When administered with 50~100mLNS or GS diluted intravenous drip, each intravenous drip time is 30 minutes. For patients with renal insufficiency, reduce the dose appropriately, for example, 10mg once. Adverse reactions after use may include intracranial hemorrhage, gastrointestinal hemorrhage, pulmonary hemorrhage, epistaxis, subcutaneous hemorrhage, disturbance of consciousness, etc. And liver dysfunction. Occasionally hypotension, anemia, leukopenia, renal dysfunction, polyuria, rash, fever, etc. Intracranial hemorrhage and possible intracranial hemorrhage patients, hypotension patients contraindicated. Preoperative diabetes, cerebral main artery arteriosclerosis, with severe disturbance of consciousness, subarachnoid hemorrhage with cerebrovascular disorders, liver and kidney dysfunction, patients over 70 years old, pregnant women and children with caution. Breast-feeding women should stop breastfeeding when taking medicine. This medicine can only be injected intravenously, and cannot be administered by other ways. |
