Profile: Wuhan Kaimubuke Pharmaceutical Technology Co., Ltd specializes in the production, sales and supply pharmaceutical intermediates. We also offer active pharmaceutical ingredients, organic intermediates, food additives, and imidazoles. The antipyretic and analgesic effect of phenacetin is similar to "acetylsalicylic acid". It is mainly used as an antipyretic and analgesic. The effect is slow and long lasting. It has good curative effect on the treatment of headache, neuralgia, arthralgia and fever. But its anti-rheumatic and anti-inflammatory effects are weak. Excessive doses can cause methemoglobinemia and cause hypoxia in the body. Long-term medication can damage the kidneys and even cause nipple necrosis. It should be used with caution. Due to its toxic side effects and the rapid development of other similar drugs, the drug has ceased to be used alone, but used as a compound preparation for raw materials and other drugs.
