# Ecospirin (Aspirin, Enteric-Coated)
## Overview
Ecospirin is an enteric-coated formulation of aspirin, a nonsteroidal anti-inflammatory drug (NSAID) with analgesic, anti-inflammatory, and antipyretic properties. The enteric coating is designed to delay the dissolution and absorption of aspirin until it reaches the small intestine, potentially reducing gastric irritation.
## Primary Indications
* **Cardiovascular protection:** Prevention of myocardial infarction and stroke in patients with established cardiovascular disease, and in certain high-risk individuals.
* **Pain and inflammation:** Management of mild to moderate pain and inflammatory conditions (though other NSAIDs or non-pharmacologic therapies may be preferred due to GI risk).
## Adult Dosing
* **Cardiovascular protection (Secondary Prevention):** 75-100 mg once daily.
* **Cardiovascular protection (Primary Prevention):** Dosing varies significantly based on individual risk assessment and local guidelines. Often 75-100 mg once daily.
* **Pain and Inflammation:** 325-650 mg every 4-6 hours as needed. Maximum daily dose typically 4000 mg, but lower doses are preferred for chronic use.
## Pediatric Dosing
Aspirin is generally **contraindicated in children and adolescents** with viral infections (e.g., influenza, varicella) due to the risk of Reye's syndrome. There is no established standard pediatric dosing for Ecospirin.
## Dose Adjustments
No specific dose adjustments are typically required for hepatic or renal impairment, but caution is advised. Higher doses may increase risk in these populations.
## Contraindications
* Known hypersensitivity to aspirin, salicylates, or NSAIDs.
* History of aspirin-induced asthma, urticaria, or other allergic-type reactions.
* Active peptic ulceration or recent gastrointestinal bleeding.
* Bleeding disorders (e.g., hemophilia).
* Severe hepatic or renal impairment.
* Children and adolescents with viral infections.
## Adverse Effects
* **Gastrointestinal:** Dyspepsia, heartburn, nausea, abdominal pain, gastritis, peptic ulceration, gastrointestinal bleeding. Enteric coating may reduce, but not eliminate, this risk.
* **Hemorrhage:** Increased risk of bleeding, particularly from the GI tract.
* **Hypersensitivity:** Bronchospasm (especially in aspirin-sensitive asthmatics), urticaria, angioedema.
* **Tinnitus and hearing loss:** More common with higher doses.
* **Reye's Syndrome:** In children and adolescents with viral infections.
## Key Drug Interactions
* **Anticoagulants (e.g., warfarin, DOACs) and antiplatelets (e.g., clopidogrel):** Increased risk of bleeding.
* **Corticosteroids:** Increased risk of GI ulceration and bleeding.
* **Methotrexate:** Aspirin can increase methotrexate toxicity.
* **NSAIDs:** Additive GI toxicity and potential for reduced aspirin's cardioprotective effect.
* **Uricosuric agents (e.g., probenecid):** Aspirin may decrease the efficacy of these agents.
* **Alcohol:** Increased risk of GI irritation and bleeding.
## Monitoring
* Signs and symptoms of gastrointestinal bleeding (melena, hematemesis, abdominal pain).
* Signs and symptoms of bleeding elsewhere (bruising, epistaxis, hematuria).
* Renal function and electrolytes, especially in patients with pre-existing renal disease or those on long-term therapy.
* Tinnitus or hearing changes, which may indicate toxicity.
## Clinical Pearls
* The enteric coating is designed to be swallowed whole and not crushed, chewed, or broken.
* While the enteric coating reduces gastric irritation, it does not eliminate the risk of GI bleeding or ulcers, especially with chronic use or higher doses.
* For immediate cardioprotection in acute coronary syndromes, non-enteric-coated aspirin is typically used to ensure rapid absorption.
* Aspirin's antiplatelet effect is irreversible and lasts for the life of the platelet (7-10 days).
