Clinical Features

• Fatigue, pale oral mucosa/lips/eyes, koilonychia, sparse hair.

• Treatment: Deferoxamine mesylate, RBC

Classification and Therapeutic Uses of NSAIDs

Classification of NSAIDs

NSAIDs (Non-Steroidal Anti-Inflammatory Drugs) are classified based on their chemical structure or COX (cyclooxygenase) enzyme selectivity.

I. Classification by COX Selectivity

1. Non-selective COX Inhibitors

These inhibit both COX-1 and COX-2 enzymes:

• Aspirin (acetylsalicylic acid)
• Ibuprofen
• Naproxen
• Indomethacin
• Ketorolac
• Diclofenac
• Piroxicam

2. Preferential COX-2 Inhibitors

These selectively inhibit COX-2 more than COX-1, but not exclusively:

• Meloxicam
• Nabumetone
• Etodolac

3. Selective COX-2 Inhibitors (Coxibs)

These minimally affect COX-1, resulting in lower GI side effects:

• Celecoxib
• Etoricoxib
• Parecoxib
• Valdecoxib (withdrawn in some countries due to cardiovascular risk)
• Rofecoxib (withdrawn
