This document discusses nonsteroidal anti-inflammatory drugs (NSAIDs), outlining their functions, classifications, and mechanisms of action. NSAIDs are known to reduce pain, fever, and inflammation, with examples including aspirin, ibuprofen, and celecoxib among others. The classification includes traditional nonselective COX inhibitors, preferential COX-2 inhibitors, and selective COX-2 inhibitors, as well as analgesics with poor anti-inflammatory properties.

2. NSAIDs
Nonsteroidal anti-inflammatory drugs (NSAIDs) are members of a drug class that reduces pain,
decreases fever, prevents blood clots, and in higher doses, decreases inflammation.
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
 Nimesulide,
 Diclofenac,
 Aceclofenac,
 Meloxicam,
 Etodolac.
C. Selective COX-2
inhibitors
 Celecoxib,
 Etoricoxib,
 Parecoxib
D. Analgesic-antipyretics
with poor
antiinflammatory action
1. Paraaminophenol
derivative: Paracetamol
(Acetaminophen).
2. Pyrazolone derivatives:
Metamizol (Dipyrone),
Propiphenazone.
3. Benzoxazocine
derivative: Nefopam.
