| Nifedipine Usage And Synthesis |
| Pharmacological effects |
Nifedipine is a kind of dihydropyridine calcium antagonists, it can inhibit the Ca2 + uptake of cardiac and vascular smooth muscles, and it can expand the coronary artery , increase coronary blood flow,and improve myocardial ischemic tolerance, at the same time, it can expand peripheral arteries and reduce peripheral vascular resistance,and relieve coronary artery spasm, and increase coronary blood flow, improve myocardial ischemia,in order to decrease the blood pressure. Small doses do not affect blood pressure, when expanding coronary artery ,it is a better anti-angina drug .It is used for the prevention and treatment of angina pectoris,with no adverse effects on respiratory function, its efficacy is best particularly for angina pectoris coronary spasm and obstructive airway disease with angina , its efficacy is superior to β-blockers.It is also applied to all types of high blood pressure, including severe and resistant hypertension. Treatment of refractory congestive heart failure may be taking this long. It is also used for the treatment of primary pulmonary hypertension, diffuse esophageal spasm and bronchial asthma, duodenal ulcers, urinary tract obstruction, exercise-induced asthma, achalasia. Nifedipine has a certain selectivity on vascular smooth muscles , the direct negative inotropic effect and denaturation effect on the heart are weak, systemic administration of it does not cause the heart rate slowing down ,on the contrary, the heart rate performances reflected increase. The above information is edited by the chemicalbook of Tian Ye. |
| Chemical properties | Yellow crystals. Melting point 172-174 ℃. Soluble in acetone, chloroform, ethyl acetate, dissolved in hot methanol, insoluble in water. It easily deteriorates in case of light. |
| Application | Long-term coronary vasodilators. This product can increase coronary blood flow, reducing myocardial oxygen consumption.it is used for acute and chronic coronary insufficiency,especially the angina and myocardial infarction. |
| Production methods | O-nitrobenzaldehyde, methyl acetoacetate, methanol, ammonia are refluxed together , then froze , crystallize,after filtration, nifedipine crude is obtained . The crude product is recrystallized through methanol .then the product is derived , yield rate is 50%. |
