Why is chirality important in ibuprofen?
As 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.
What is the structure of ibuprofen?

Ibuprofen/Formula
Is ibuprofen an enantiomer?
Ibuprofen is a chiral drug existing in two enantiomeric forms: S-(+) and R-(−). The NSAID activity of ibuprofen has been reported to reside in the S-(+)-enantiomer [14] [15][16], which is now marketed in a number of countries as dexibuprofen; however, in most countries, the drug is used as the racemate.
Which enantiomer of ibuprofen is active?
The two optical isomers of ibuprofen are identified by the prefixes R- and S+. The stereoisomers are similar in properties such as melting point, boiling point and solubility. The S+ form is the more pharmacologically active form and the R- form has no anti-inflammatory effect.
Does ibuprofen have a chiral carbon?
Ibuprofen, like other 2-arylpropionate derivatives (including ketoprofen, flurbiprofen, naproxen, etc), contains a chiral carbon in the α-position of the propionate moiety. As such, there are two possible enantiomers of ibuprofen, with the potential for different biological effects and metabolism for each enantiomer.
How does R ibuprofen affect S ibuprofen?
Racemic ibuprofen, which contains equal quantities of R(-)-ibuprofen and S(+)-ibuprofen, has been used as an anti-inflammatory and analgesic agent for over 30 years. Although the S(+)-enantiomer is capable of inhibiting cyclooxygenase (COX) at clinically relevant concentrations, R(-)-ibuprofen is not a COX inhibitor.
How many chiral carbons are in the structure of ibuprofen?
7

Is ibuprofen a molecule?
Ibuprofen is a frequently used over-the-counter drug for treating pain, inflammation, and fever. It is a relatively simple molecule that was discovered and developed in the 1950s and 1960s at Boots Pure Drug in Nottingham, UK (now Boots UK in Beeston).
How ibuprofen is metabolized?
Ibuprofen is rapidly metabolized and eliminated in the urine thus, this via accounts for more than 90% of the administered dose. It is completely eliminated in 24 hours after the last dose and almost all the administered dose goes through metabolism, representing about 99% of the eliminated dose.
