Although it possesses
a chiral centre
, with only the S-enantiomer possessing beneficial pharmacological activity, all ketoprofen preparations to date are marketed as the racemate.
Does ibuprofen have chiral center?
The
ibuprofen
molecule possesses a
chiral
carbon in the α-position to the carboxyl function (see Fig. 1), therefore it may exist as an R or S enantiomeric form.
Which NSAIDs have no chirality?
Although it possesses
a chiral centre
, with only the S-enantiomer possessing beneficial pharmacological activity, all ketoprofen preparations to date are marketed as the racemate.
Is naproxen chiral?
1 Introduction. Naproxen, a
chiral compound
, is often used as a nonsteroidal anti-inflammatory analgesic drug.
Which NSAIDs are nonselective?
- Diclofenac.
- Diflunisal.
- Etodolac.
- Fenoprofen.
- Flurbiprofen.
- Ibuprofen.
- Indomethacin.
- Ketoprofen.
Is ketoprofen an Nsaid?
Ketoprofen is in a
class of medications called NSAIDs
. It works by stopping the body’s production of a substance that causes pain, fever, and inflammation.
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.
What’s a substitute for ibuprofen?
There are times when NSAIDs (Non-steroidal anti-inflammatory drugs), such as Motrin, ibuprofen,
Aleve, naproxen, Celebrex, Indocin, indomethacin
, and aspirins, are appropriate, especially in the acute setting over a short course to reduce inflammation.
What objects are chiral?
An achiral object is identical with (superimposable on) its mirror image. Chiral objects have a “handedness”, for example,
golf clubs, scissors, shoes and a corkscrew
. Thus, one can buy right or left-handed golf clubs and scissors. Likewise, gloves and shoes come in pairs, a right and a left.
Is naproxen S or R?
Naproxen is marketed as the
(S) isomer
, which has 28 times the anti-inflammatory activity of the (R) isomer. Naproxen is available in two forms: a salt form, naproxen sodium (Anaprox and Aleve), and a base form (Naprosyn).
What class of drug is naproxen?
Naproxen is in a class of medications called
NSAIDs
. It works by stopping the body’s production of a substance that causes pain, fever, and inflammation.

When should NSAIDs be avoided?
When possible, NSAIDs should be avoided in persons with
preexisting renal disease
, congestive heart failure, or cirrhosis to prevent acute renal failure.
Are all NSAIDs COX-2 inhibitors?

Which NSAIDs are COX-1 inhibitors?
Among the traditional NSAIDs, other then aspirin and indomethacin, only few examples of selective COX-1 inhibitors (
SC-560, FR122047, mofezolac, P6 and TFAP
) have been so far identified. This review has also the scope to stimulate the development of novel drugs, which activity is COX-1 mediated.
Is ketoprofen stronger than ibuprofen?
Conclusions. The result of this meta-analysis shows that
ketoprofen is more effective than ibuprofen in managing RA pain at therapeutic doses
, thus supporting its use in clinical practice.
