Function and ApplicationFunction
The antipyretic and analgesic effect of butazone is less than that of acetylsalicylic acid, and the toxicity is larger, so it is generally not used as antipyretic and analgesic medicine, but its anti-inflammatory effect is strong, and can be used to treat rheumatic and rheumatoid arthritis, acute gouty arthritis, ankylosing spondylitis. In addition, this product can reduce the reabsorption of urate from renal tubules, has a mild urination effect, and can also be used for acute gout patients. It is often given continuously or in combination with other drugs. It can also be used to treat fever caused by acute hemocytosis, acute lymphangitis of filaria, tuberculosis, malignant tumor, etc. Recent studies have found that the mechanism of anti-inflammatory, analgesic and anti-rheumatic effects of butazone is not due to hypophysial-adrenal excitation, but may be due to the inhibition of active substances related to inflammation in inflammatory tissues, such as the synthesis of prostaglandins, the activity and transfer of white blood cells, the release and activity of lysosomal enzymes. Analgesia may also be the result of inhibiting prostaglandin synthesis.
