# 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 dissolution until the drug reaches the small intestine, reducing gastric irritation.
## Primary Indications
* **Pain and Inflammation:** Mild to moderate pain and inflammatory conditions (though typically not the first-line choice for acute pain due to GI risks).
* **Cardiovascular Prevention:** Secondary prevention of myocardial infarction and stroke; primary prevention in select high-risk individuals.
* **Rheumatic Fever Prophylaxis:** Treatment and prophylaxis.
## Adult Dosing
* **Pain and Inflammation:**
* 325 mg to 650 mg orally every 4 to 6 hours as needed.
* Maximum: Typically 4000 mg per day, but lower in specific populations.
* **Cardiovascular Prevention:**
* **Secondary Prevention:** 75 mg to 162 mg orally once daily.
* **Primary Prevention:** 75 mg to 162 mg orally once daily (individualized decision based on risk assessment).
* **Rheumatic Fever Prophylaxis:**
* **Treatment:** 60 mg/kg/day orally divided every 4 to 6 hours.
* **Prophylaxis:** 25 mg/kg/day orally once daily or divided.
* Maximums vary based on indication and patient weight.
## Pediatric Dosing
* **Pain and Inflammation:** Dosing is weight-based and should be done with caution due to the risk of Reye's syndrome. Typical doses range from 10 mg/kg/dose to 15 mg/kg/dose orally every 4 to 6 hours.
* Maximum: 60 mg/kg/day or 3600 mg/day, whichever is less.
* **Reye's Syndrome:** Aspirin is **contraindicated** in children and teenagers with viral infections (e.g., influenza, chickenpox) due to the risk of Reye's syndrome.
* **Kawasaki Disease:** Specific dosing protocols are used under specialist guidance.
## Dose Adjustments
No specific dose adjustments are typically required for renal or hepatic impairment, however, caution is advised. Dose should be individualized.
## Contraindications
* Known hypersensitivity to aspirin or other NSAIDs.
* Children and teenagers with viral infections.
* Active peptic ulcer disease or recent gastrointestinal bleeding.
* Severe hepatic impairment.
* Severe renal impairment.
* Severe heart failure.
* Late pregnancy (third trimester).
* Bleeding disorders.
## Adverse Effects
* **Gastrointestinal:** Dyspepsia, nausea, vomiting, abdominal pain, gastritis, peptic ulceration, GI bleeding.
* **Hematologic:** Increased bleeding time, thrombocytopenia, anemia.
* **Hypersensitivity:** Bronchospasm, urticaria, angioedema.
* **Other:** Tinnitus, dizziness, headache, Reye's syndrome (in children/teenagers with viral infections).
## Key Drug Interactions
* **Anticoagulants (e.g., warfarin, heparin, DOACs):** Increased risk of bleeding.
* **Other NSAIDs and COX-2 Inhibitors:** Increased risk of GI toxicity and bleeding.
* **Corticosteroids:** Increased risk of GI ulceration and bleeding.
* **Methotrexate:** Increased risk of methotrexate toxicity.
* **Antihypertensives (e.g., ACE inhibitors, ARBs, diuretics):** Reduced antihypertensive effect; increased risk of renal dysfunction.
* **Selective Serotonin Reuptake Inhibitors (SSRIs):** Increased risk of bleeding.
* **Alcohol:** Increased risk of GI bleeding.
## Monitoring
* **Signs of GI bleeding:** Melena, hematemesis, abdominal pain.
* **Signs of bleeding elsewhere:** Ecchymoses, epistaxis, prolonged bleeding from cuts.
* **Renal function:** Especially in patients with pre-existing renal disease or those on concomitant nephrotoxic agents.
* **Tinnitus:** May indicate toxicity.
## Clinical Pearls
* The enteric coating of Ecospirin should not be crushed or chewed to maintain its protective function.
* Due to the risk of Reye's syndrome, aspirin should be avoided in children and adolescents with suspected viral infections.
* Cardiovascular doses are typically lower and taken daily.
* Patients with a history of GI ulcers or bleeding, elderly patients, and those taking concomitant medications that increase bleeding risk require closer monitoring.
