Physical and Chemical Properties | Light yellow viscous liquid. Soluble in cold water, but insoluble in hot water. Soluble in most organic solvents for cough medicine, antitussive effect intensity slightly lower than codeine, but does not inhibit breathing, bronchial asthma patients after medication, the reaction can deepen breathing, minute ventilation increased. |
Use | Commonly used in acute bronchitis, bronchial asthma, Pneumonia, lung cancer caused by the stimulation of Dry Cough, such as cough. The preparation was sugar-coated pills. |
Toxicity | LD50 oral in mouse: 400mg/kg |
Raw Materials | 4-Nitrobenzoic acid |
introduction | benzozonate is a peripheral non-addictive antitussive. It has a strong local anesthetic effect on respiratory tract receptors, has a significant inhibitory effect on lung stretch receptors and sensory nerve tips, inhibits lung vagus nerve reflex, reduces the afferent of cough impulse, and has a certain inhibitory effect on the cough center. |
effect | antitussive effect is slightly weaker than codeine phosphate, but does not affect the respiratory center, and antitussive drug can increase lung ventilation. It is used for irritating dry cough caused by acute bronchitis, lung cancer, pneumonia, etc., and to prevent cough during bronchoscopy, laryngoscopy, and bronchography. |
use | antitussive. |
production method | ethyl p-aminobenzoate is first condensed with bromobutane at 140-150 ℃, and then condensed with polyethylene glycol methyl ether at 105 ℃ to obtain cough. |
