## Ecospirin (Aspirin Enteric-Coated)
**Overview**
Ecospirin is an enteric-coated formulation of aspirin, a nonsteroidal anti-inflammatory drug (NSAID) with analgesic, antipyretic, and antiplatelet properties. The enteric coating is designed to delay the release of aspirin until it reaches the small intestine, which may reduce gastric irritation.
**Primary Indications**
* Pain relief (mild to moderate)
* Fever reduction
* Inflammation reduction
* Prevention of cardiovascular events (e.g., myocardial infarction, stroke) in specific patient populations (e.g., secondary prevention)
**Adult Dosing**
Dosing varies significantly based on indication:
* **Analgesic/Antipyretic/Anti-inflammatory:**
* 325 mg to 650 mg every 4 to 6 hours as needed.
* Maximum: 4000 mg per 24 hours.
* **Cardiovascular Prevention (Secondary Prevention):**
* Typically 75 mg to 100 mg once daily.
* Dose can vary based on specific guidelines and physician preference. Higher doses (e.g., 325 mg daily) may be used initially in certain acute settings.
**Pediatric Dosing**
Use in children under 16 years of age for viral infections (influenza, varicella) is generally **contraindicated** due to the risk of Reye's syndrome.
For other indications (e.g., Kawasaki disease), specific pediatric dosing protocols are followed, often under specialist guidance. Dosing is typically weight-based. Consult specific pediatric guidelines.
**Dose Adjustments**
* **Renal Impairment:** Use with caution. Dose reduction may be necessary in severe impairment, but specific guidelines are lacking. Monitor for signs of toxicity.
* **Hepatic Impairment:** Use with caution. Monitor liver function.
**Contraindications**
* Hypersensitivity to aspirin, salicylates, or NSAIDs.
* History of bronchospasm, asthma, rhinitis, or urticaria induced by aspirin or other NSAIDs.
* Active peptic ulcer disease or history of recurrent gastrointestinal (GI) bleeding.
* Children and adolescents with viral infections.
* Severe hepatic or renal impairment.
* Severe heart failure.
* Hemophilia and other hemorrhagic diatheses.
**Adverse Effects**
* **Common:** GI upset, heartburn, nausea, dyspepsia.
* **Serious:** GI bleeding, ulceration, perforation, tinnitus (especially at higher doses), dizziness, allergic reactions (including anaphylaxis), bronchospasm, renal toxicity, hepatic dysfunction.
**Key Drug Interactions**
* **Anticoagulants (e.g., warfarin, heparin, DOACs):** Increased risk of bleeding.
* **Other NSAIDs/COX-2 Inhibitors:** Increased risk of GI toxicity and reduced antiplatelet effect of aspirin.
* **Corticosteroids:** Increased risk of GI ulceration and bleeding.
* **Antihypertensives (e.g., ACE inhibitors, ARBs, beta-blockers):** May reduce antihypertensive efficacy; increased risk of renal impairment.
* **Methotrexate:** Increased methotrexate toxicity.
* **Uricosuric agents (e.g., probenecid):** Reduced uricosuric effect.
* **Valproic acid:** Increased valproic acid levels and toxicity.
* **Selective Serotonin Reuptake Inhibitors (SSRIs):** Increased risk of bleeding.
**Monitoring**
* **For pain/fever/inflammation:** Monitor for efficacy and signs of GI distress or bleeding.
* **For cardiovascular prevention:** Monitor for efficacy and signs of bleeding (e.g., bruising, melena, hematochezia).
* **Renal and hepatic function** in patients with pre-existing impairment or on long-term therapy.
* **Signs of salicylism** (tinnitus, hearing loss, dizziness, confusion) at higher doses.
**Clinical Pearls**
* Enteric-coated aspirin should be swallowed whole and not crushed, chewed, or broken to maintain the integrity of the coating.
* Take with food or a full glass of water to minimize GI upset.
* The antiplatelet effect of aspirin is irreversible and lasts for the life of the platelet (7-10 days).
* Discontinue aspirin at least 5-7 days before elective surgery.
* Use cautiously in patients with a history of gout.
