了解药品的性质对药工人員来說是非常重要的,如对某些药物性质不了解有时就会造成約物的变质,以致疗效降低或失去药用价值,甚至毒性增强,有發生危險的可能。現就引起药物变质主要原因之一的氧化作用加以討論。露置于空气中的药物常常易与氧化合而变质,氧化反应过程多为与氧化合或脫氢,而使药物結構改变,产生氧化产物。于空气中易氧化的药物如: 酚类如苯酚、甲酚(煤酚)、間苯二酚等的氧化反应比较复杂,一般在空气中放置过久,可被氧化变红。颜 Understanding the nature of drugs is very important for pharmacists. If you do not understand the properties of certain drugs, they sometimes cause deterioration of the substances, resulting in reduced efficacy or loss of medicinal value, and even increased toxicity. There may be danger. . The oxidation of one of the main causes of drug deterioration is now discussed. Drugs exposed in the air are often susceptible to oxidation and deterioration, and the oxidation process is mostly combined with oxidation or dehydrogenation, which changes the drug structure and produces oxidation products. Easily oxidized drugs in the air such as: Phenols such as phenol, cresol (phenol), resorcinol oxidation reaction is more complex, generally placed in the air for too long, can be oxidized red. Yan
