introduction | cyclomentyl ester (cyclandelate), also known as anmai sheng and antithrombotic pills, has a chemical name of 3,3, 5-trimethylcyclohexanol-dl-mandelate, which is an excellent vasodilator developed by Elan Company in Ireland. Cyclotonsil is used to treat cardiovascular and cerebrovascular diseases such as hypertension and peripheral vascular disorders of the limbs. It can activate the nerves and reduce blood coagulation. It is currently one of the commonly used medicines in clinical practice. |
Pharmacology and toxicology | The structure is similar to papaverine. Single or continuous administration can increase blood flow in brain, heart, kidney and limbs. It can directly relax vascular smooth muscle to dilate blood vessels, and has a selective and continuous expansion effect on the brain, kidney, blood vessels and coronary arteries, thereby increasing blood flow. The effect is weaker and longer-lasting than papaverine. This product can still promote collateral circulation. It has little effect on respiration, heart rate, cardiac output, myocardial oxygen consumption, blood pressure, etc. |
pharmacokinetics | oral absorption is fast and complete, it takes effect in 10-15 minutes, the blood concentration peaks in 1.5 hours, and it can be maintained for 4-6 hours. Most of them are excreted in urine and about 5% from feces. |
Indications | Used for ischemic cerebrovascular diseases, cerebral arteriosclerosis, brain trauma sequelae, acral arterial spasm, hand-foot cyanosis, obliterative endarteritis, inner ear vertigo, etc. |
adverse reactions | can cause nausea, vomiting, loss of appetite, upper abdominal discomfort, sometimes facial flushing, dizziness, headache, rash, pruritus, dry mouth, palpitations, hypotension, numbness, tremor, tachycardia, sweating, etc. |
taboo | severe acute phase of cerebrovascular accident, pregnant women and lactating women are prohibited. patients with severe occlusive coronary artery and cerebrovascular diseases, glaucoma, hemorrhage or bleeding tendency should be used with caution. |
use | suitable for cerebral arteriosclerosis, cerebral strain, cerebral trauma and venous embolism. suitable for the treatment of cerebral arteriosclerosis, brain injury and venous embolism |
