Abstract(s)
The chirality of drugs is an important issue for the pharmaceutical industry, since the different
enantiomers of a racemic drug may have distinct pharmacological activities, pharmacokinetic and
pharmacodynamic effects. Because of its chiral selectivity, human body reacts with a racemic drug
differently, and metabolise each enantiomer on separate pathways producing different
pharmacological activity. Thus, one isomer may produce the desired therapeutic activities, while the
other may be inactive or even, in worst cases, produce unwanted effects.
Flurbiprofen [2-(2-fluoroo4-biphenyl)-propionic acid] and ketoprofen [2-(3-benzoylphenyl)-propionic
acid] belong to a family of chemicals named 2-arylpropionic acids, or profens, an important sub-class
of the frequently prescribed and used drugs called nonsteroidal anti-inflammatory drugs (NSAIDs). A
considerable number of these drugs possess antipyretic activity in addition to its analgesic and antiinflammatory
actions, and thus have utility in the treatment of fever. The main primary indications for
NSAIDs therapy include rheumatoid arthritis, osteoarthritis, acute gouty arthritis, ankylosing
spondylitis and dysmenorrhea (DeRuiter, 2002). The importance of this class of drugs is supported by
U,e fact that, in the last twenty years, drugs like aspirin, phenazone derivatives or acetaminophen are
being supplemented by profens (Brune and Hinz, 1998).
