Example- Aspirin, paracetamol, ibuprofen, ketoprofen, diclofenac etc.


Classification of NSAIDs:




















A. Nonselective COX
inhibitors (traditional
NSAIDs)

1. Salicylates: Aspirin.
2. Propionic acid
derivatives: Ibuprofen,
Naproxen, Ketoprofen,
Flurbiprofen.
3. Fenamate: Mephenamic
acid.
4. Enolic acid derivatives:
Piroxicam, Tenoxicam.
5. Acetic acid derivatives:
Ketorolac, Indomethacin,
Nabumetone
6. Pyrazolone derivatives:
Phenylbutazone,
Oxyphenbutazone.





B. Preferential
COX-2 inhibitors

 Diclofenac,
 Aceclofenac,
 Meloxicam,
 Etodolac.
C. Selective COX-2
inhibitors

 Etoricoxib,
 Parecoxib
D. Analgesic-antipyretics
with poor
antiinflammatory action

1. Paraaminophenol
derivative: Paracetamol
(Acetaminophen).
2. Pyrazolone derivatives:
