Central pontine myelinolysis causes: |
The most common cause of central pontine myelinolysis is a quick change in the body's sodium levels. This most often occurs when someone is being treated for low blood levels of sodium (hyponatremia) and the sodium is replaced too fast. It also can occasionally occur when high levels of sodium in the body (hypernatremia) are corrected too quickly. |

|
Drugs that treat fever and mechanism? |
ASA, acetaminophen and ibuprofen are cyclooxygenase (COX) inhibitors that block the formation of prostaglandin E2 in the hypothalamus and effectively control fever. |
