Naprosyn is an nonsteroidal anti-inflammatory drug. That is, it relieves pain, heat and inflammation. This is achieved by reducing the production of substances (arachidic acid and prostaglandin) that causes inflammatory reactions. On the one hand, such reactions are intended to protect the health of the whole body by destroying the disease-causing agents (for example, bacteria) in one organ. However, they often make the person suffer, as they worsen the general condition. Therefore, anti-inflammatory medications are so important in medicine.
The drug is used for the treatment of the following diseases:

  • Pains in the joint, for example, in osteoarthritis, spondylitis, gout, etc.
  • Muscle pains, caused by traumas
  • Neuralgia
  • Pains, caused by the disorder of reproductive system in women, for example, in adnexitis, algodysmennorhea
  • Headache
  • Toothache
  • Diseases of ENT-organs

The duration of treatment course usually doesn’t exceed two weeks. The anti-inflammatory effect starts to appear at the end of the first week. The pains pass earlier.
