Webb26 okt. 2024 · Ibuprofen is a non–steroidal anti-inflammatory drug that is used to treat conditions such as headaches and muscle pains. Ibuprofen exists as 2 enantiomers — the R (-) ibuprofen and the S (+) ibuprofen. Of the two enantiomers, S-ibuprofen is a more potent inhibitor of the cyclooxygenase enzyme than R-ibuprofen [2], and hence is more ... WebbAs is the case with numerous other drugs, Ibuprofen is a chiral compound. The human body with its numerous homochiral compounds will interact with each racemic drug differently and metabolize each enantiomer by a separate pathway to generate a different pharmacokinetic and pharmacodynamic activity.
