Solid phase membrane tip extraction - microemulsion electrokinetic chromatography of selected non-steroidal anti-inflammatory drugs

Arylalkanoic acid drugs belong to the group of non-steroidal antiinflammatory drugs (NSAIDs). These drugs are often used for the treatment of fever and minor pain due to its capability to inhibit prostaglandin productions which act as a messenger molecule in human body. There are many methods used i...
