Aminophenol dihydrocodeine tablets can be used clinically for the treatment of pain of moderate intensity or above, with a relatively obvious analgesic effect, especially for some patients with a lower pain threshold and a more sensitive constitution. Aminophenol dihydrocodeine tablets is a compound preparation, of which aminophenol is acetaminophen, which belongs to the non-steroidal class of anti-inflammatory, antipyretic and analgesic drugs, and can often be used for the treatment of analgesia. The pain-relieving effect of dihydrocodeine is similar to codeine, but because of the dihydrogen, the addictive properties are greatly reduced, so dihydrocodeine is less addictive. Aminophenol dihydrocodeine tablets have the superimposed effect of the above two, and can be used clinically for the treatment of pain, such as toothache, headache, dysmenorrhea, or pain caused by lumbar muscle strain, rheumatoid arthritis, ankylosing spondylitis, as well as shoulder and back muscle pain of cervical origin, thoracic nerve pain in the chest, and also for the treatment of post-surgical pain and cancer pain. In addition, it can be used in combination with gabapentin or pregabalin to treat herpes zoster neuralgia. Because acetaminophen is an ingredient in Aminophen Dihydrocodeine Tablets, acetaminophen is a gastrointestinal stimulant, and nausea and vomiting may occur after oral administration of codeine, it is recommended to take Aminophen Dihydrocodeine Tablets as prescribed by the doctor.
