Fenbid, also known as ibuprofen extended-release capsules, is a drug with anti-inflammatory, analgesic and antipyretic properties. For most cases of low back pain caused by sterile inflammation, such as prostaglandin factor, this drug can effectively eliminate prostaglandin factor, thus effectively relieving most cases of low back pain. The reason for this is that there are many causes of low back pain, and there are now as many as 200 known causes of low back pain. If the back pain is caused by lumbar disc herniation, or the back pain is caused by prolonged one posture or prolonged repetition of certain movements, the use of Fenbid can provide good relief. However, if the back pain is caused by tumor disease or septic infection, the effect of Fenbid treatment is less effective.
