CAS NO.479-18-5
High Quality 479-18-5 free sample Diprophylline on hot selling
Dihydroxypropyltheophylline is also known as asthmatic, and its chemical name is 1,3-dimethyl -7-(2,3 dihydroxypropyl)-3, 7-dihydro-1H-purin-2, 6-dione. It is a commonly used clinical antiasthmatic drug. It is a xanthine derivative of the condensation of theophylline and monochlorodipropanol, the antiasthmatic effect is similar to aminophylline. Its bronchial dilation effect is about 1/10 of aminophylline, and the cardiac excitation effect is only 1/20~1/10 of aminophylline. This product has little pain response after intramuscular injection, and has little irritation to gastrointestinal tract after oral administration. The oral bioavailability is 70% and the half-life is about 2 hours. It is not metabolized in the body, and most of it is excreted in the urine in its original form. It is clinically used for the relief of wheezing symptoms such as bronchial asthma, asthmatic bronchitis, and obstructive emphysema. It can also be used for cardiogenic asthma, especially for asthma patients with tachycardia and cannot tolerate theophylline. Theophylline Theophylline is an alkaloid that exists in tea, coffee and other plants. It is a derivative of methylxanthine. It has more prednisone to relax bronchial smooth muscle, excite the heart and diuresis. Theophylline is widely used in clinical practice, mainly for the treatment of bronchial asthma, cardiogenic asthma and cardiogenic edema. When theophylline is used as a bronchodilator, its effective concentration in plasma (5~20mg/L) should be strictly controlled to avoid side effects due to excessive concentration. Aminophylline Aminophylline is a compound salt of theophylline and ethylenediamine. Its pharmacological effects mainly come from theophylline, and ethylenediamine enhances its water solubility. This product has a direct relaxation effect on respiratory smooth muscle. In addition, theophylline is a purine receptor blocker, which can resist the contractile effect of adenine on the respiratory tract. Theophylline can enhance the contractility of the diaphragm, especially when the diaphragm is weak, so it is beneficial to improve respiratory function. This product can still slightly relax coronary arteries, peripheral blood vessels and bile duct smooth muscle, and slightly increase myocardial contractility and slight diuresis.
