## Ecospirin (Aspirin Enteric-Coated)
### Overview
Ecospirin is an enteric-coated formulation of aspirin, a nonsteroidal anti-inflammatory drug (NSAID) with analgesic, antipyretic, anti-inflammatory, and antiplatelet properties. The enteric coating is designed to delay absorption and reduce gastric irritation.
### Primary Indications
* **Analgesia and Antipyresis:** Mild to moderate pain and fever.
* **Antiplatelet Therapy:** Prevention of cardiovascular events (e.g., myocardial infarction, stroke) in high-risk individuals.
### Adult Dosing
Dosing is highly variable based on indication.
* **Analgesia/Antipyresis:**
* **Immediate-release (non-enteric-coated) aspirin:** 325 mg to 650 mg orally every 4 to 6 hours as needed.
* **Maximum:** 4000 mg per 24 hours.
* *Note: Enteric-coated aspirin has slower absorption; immediate-release is generally preferred for acute pain/fever relief. If used for these indications, higher doses may be required due to delayed absorption.*
* **Cardiovascular Prevention (Antiplatelet):**
* **Low-dose:** 81 mg to 325 mg orally once daily.
* *Note: Specific dosing for secondary prevention is typically guided by cardiology guidelines and individual patient risk assessment.*
### Pediatric Dosing
Aspirin is generally **contraindicated** in children and teenagers with viral illnesses (e.g., influenza, chickenpox) due to the risk of Reye's syndrome. Limited data exists for other pediatric indications.
### Dose Adjustments
* **Renal Impairment:** Use with caution. Severe renal impairment may require dose reduction or avoidance.
* **Hepatic Impairment:** Use with caution.
* **Elderly:** Increased risk of gastrointestinal bleeding and other adverse effects; lower doses may be appropriate.
### Contraindications
* Hypersensitivity to aspirin, salicylates, NSAIDs, or any component of the formulation.
* Active peptic ulceration or gastrointestinal bleeding.
* Children and teenagers with viral infections.
* Severe hepatic impairment.
* Severe renal impairment.
* History of aspirin-induced asthma or urticaria.
* Hemophilia and other bleeding disorders.
### Adverse Effects
* **Common:** Dyspepsia, heartburn, nausea, abdominal pain.
* **Serious:**
* Gastrointestinal bleeding, ulceration, perforation.
* Hemorrhage (including intracranial).
* Hypersensitivity reactions (bronchospasm, urticaria, angioedema).
* Tinnitus (often dose-related).
* Reye's syndrome (in children/teenagers with viral illness).
* Renal dysfunction.
### Key Drug Interactions
* **Anticoagulants (e.g., warfarin, heparin, DOACs):** Increased risk of bleeding.
* **Other NSAIDs and COX-2 Inhibitors:** Increased risk of gastrointestinal toxicity and bleeding.
* **Corticosteroids:** Increased risk of gastrointestinal ulceration and bleeding.
* **Antihypertensives (e.g., ACE inhibitors, ARBs, beta-blockers):** May decrease antihypertensive efficacy.
* **Diuretics:** May decrease diuretic efficacy and increase risk of renal toxicity.
* **Methotrexate:** May increase methotrexate toxicity.
* **Uricosuric agents (e.g., probenecid):** May decrease efficacy.
* **Selective Serotonin Reuptake Inhibitors (SSRIs):** Increased risk of bleeding.
* **Alcohol:** Increased risk of gastrointestinal bleeding.
### Monitoring
* **Signs and symptoms of gastrointestinal bleeding:** Melena, hematemesis, abdominal pain.
* **Signs and symptoms of salicylate toxicity:** Tinnitus, dizziness, confusion, hyperventilation.
* **Renal and hepatic function** with long-term or high-dose use.
* **Bleeding time/platelet function** if clinically indicated.
### Clinical Pearls
* The enteric coating of Ecospirin should **not** be crushed or chewed to prevent premature release of aspirin and increased gastric irritation.
* For acute pain or fever, immediate-release aspirin is generally preferred over enteric-coated formulations due to faster onset of action.
* Enteric-coated aspirin is primarily used for chronic conditions requiring antiplatelet effects or for patients who cannot tolerate non-coated aspirin due to gastric upset, although the risk of GI bleeding still exists.
* In patients requiring aspirin for cardiovascular protection who also have a history of GI bleeds or ulcers, concomitant gastroprotection (e.g., PPI) may be considered.
