**Aspirin/Acetylsalicylic acid**

👉 **Class: Non-steroidal anti-inflammatory drug (NSAID)**

![image](https://canada1.discourse-cdn.com/flex033/uploads/medbound/original/2X/2/2c6166d431bce492fd18a4006b3f2e4e03bc5b45.png)

👉 **Mechanism of action**

✅ **Non-selective, irreversible inhibitor of the Cyclooxygenase enzymes (COX-1 & COX-2)**

✅ Prevents conversion of arachidonic acid into Prostaglandins (PGs) & Thromboxane (TXA2)

✅ **↓ PGs:**** ↓ pain, fever, and inflammation**

✅ **↓ TXA2: Inhibits platelet aggregation**

⚕ **Therapeutic uses**

✅ **Analgesic** - For headache including mild migraine, backache, myalgia, joint pain, pulled muscle, toothache, neuralgias and dysmenorrhea

✅ **Acute Rheumatic fever**

✅ **Rheumatoid arthritis** (Anti-inflammatory dose 3-5 g/day)

✅ **Post MI & post stroke** (Anti platelet dose - 60–150 mg/day)

✅ **Prevention of Preeclampsia**

✅ **Treat Familial colonic polyposis and prevent colon cancer**

✅ **Prevents flushing upon nicotinic acid ingestion**

❌ **Adverse effects**

✨ Nausea, vomiting, epigastric distress, occult blood loss in stools

✨ **Gastric mucosal damage and peptic ulceration: MOST IMPORTANT ADVERSE EFFECT**

✨ **Hypersensitivity and idiosyncrasy** - Infrequent, includes rashes, fixed drug eruption, urticaria, rhinorrhea, angioedema, **asthma** and anaphylactoid reaction.

✨ **Salicylism** - syndrome produced by Anti-inflammatory doses (3–5 g/day); characterized by dizziness, tinnitus, vertigo, reversible impairment of hearing and vision, excitement, hyperventilation and electrolyte imbalance.

✨ **Reye’s syndrome** - Rare; causes rapid brain swelling & liver failure; affects children recovering from viral infections

✨ **Acute salicylate poisoning** - more common in children

💊 🧪 **Drug interactions of Aspirin**

✅ Warfarin/Methotrexate/Phenytoin + Aspirin -------- TOXICITY (OVERDOSE) & BLEEDING IN PATIENTS ON WARFARIN

✅ Probenecid + Aspirin --------- GOUT FLARE UP (↓ URIC ACID EXCRETION)

✅ Diuretics + Aspirin ------- FLUID RETENTION + ↓ BP CONTROL

❌ 💊 **Precautions and Contraindications**

✨ **Aspirin is contraindicated in patients** with Peptic ulcer, bleeding tendencies, children suffering from viral infections & chronic liver disease.

✨ **Avoid Aspirin in** G-6PD deficient individuals, during pregnancy & lactation, diabetes, congestive heart failure & juvenile rheumatoid arthritis

✨ **Aspirin should be stopped** 1 week before elective surgery.

💟🫧 **Exam pearls**

👉 Aspirin: Less potent & efficacious analgesic than Morphine.

👉 Aspirin + Paracetamol/Codeine = ADDITIVE DRUG COMBINATION

👉 Achlorhydria ↓ Aspirin absorption

👉 Teratogenic effect of Aspirin ---- Premature closure of ductus arteriosus

👉 Aspirin delay the initiation of labor and also prolong its duration

👉 Ibuprofen + low dose Aspirin – Prevent COX inhibition by Aspirin — abolishes the antiplatelet and cardioprotective effect of Aspirin

👉 Nimesulide — Choice of NSAID in patients with Aspirin induced bronchospasm
