# Ecospirin (Aspirin) Enteric-Coated
## Overview
Ecospirin is a brand name for enteric-coated aspirin. Aspirin is a nonsteroidal anti-inflammatory drug (NSAID) that acts as an antiplatelet agent, analgesic, and antipyretic. The enteric coating is designed to prevent gastric irritation by delaying absorption until it reaches the small intestine.
## Primary Indications
* **Cardiovascular risk reduction:** Primary and secondary prevention of myocardial infarction and stroke in patients with established cardiovascular disease or specific risk factors.
* **Pain and inflammation:** Relief of mild to moderate pain and reduction of fever.
* **Rheumatic conditions:** Management of pain and inflammation associated with conditions like rheumatoid arthritis, osteoarthritis, and rheumatic fever.
## Adult Dosing
* **Cardiovascular Prophylaxis:**
* **Primary Prevention:** Typically 75-100 mg once daily. Use is controversial and based on individual risk assessment; consult guidelines.
* **Secondary Prevention:** Typically 75-100 mg once daily. Higher doses (e.g., 325 mg) may be used for initial loading in acute cardiovascular events, followed by a maintenance dose.
* **Pain and Fever:** 325 mg to 650 mg every 4 to 6 hours as needed. Maximum daily dose generally 4000 mg.
* **Rheumatic Conditions:** Doses range from 2.4 g to 3.6 g daily, divided into multiple doses, typically every 4 to 6 hours.
*Dosing for Ecospirin will depend on the specific strength of the product available and the indication. Always verify the available tablet strength.*
## Pediatric Dosing
* **Pain and Fever:** Dosing is generally based on weight. A common starting dose is 10-15 mg/kg per dose every 4 to 6 hours. **Aspirin is generally not recommended for children and adolescents due to the risk of Reye's syndrome, especially during viral illnesses.** Use should be reserved for specific indications under strict medical supervision.
## Dose Adjustments
No dose adjustment is typically required for renal or hepatic impairment unless severe. However, caution is advised in these populations due to increased risk of adverse effects.
## Contraindications
* Known hypersensitivity to aspirin, salicylates, NSAIDs, or any component of the formulation.
* Children and teenagers with viral infections (e.g., influenza, chickenpox) due to the risk of Reye's syndrome.
* Active peptic ulceration or recent gastrointestinal bleeding.
* Severe hepatic impairment.
* Severe renal impairment.
* Hemophilia and other bleeding disorders.
* Asthma with nasal polyps and angioedema.
## Adverse Effects
* **Gastrointestinal:** Dyspepsia, heartburn, nausea, vomiting, abdominal pain, gastritis, peptic ulceration, GI bleeding. The enteric coating may reduce but not eliminate the risk of GI upset.
* **Hematologic:** Increased bleeding time, bruising, epistaxis, prolonged prothrombin time.
* **Hypersensitivity:** Urticaria, angioedema, bronchospasm (especially in aspirin-sensitive asthmatics), anaphylaxis.
* **Renal:** Sodium retention, renal insufficiency, interstitial nephritis.
* **Hepatic:** Elevated liver enzymes, liver damage (rare).
* **Auditory:** Tinnitus, hearing loss (often dose-related).
* **Reye's Syndrome:** In children and adolescents 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.
* **Selective Serotonin Reuptake Inhibitors (SSRIs) and Serotonin-Norepinephrine Reuptake Inhibitors (SNRIs):** Increased risk of bleeding.
* **Methotrexate:** Aspirin can increase methotrexate levels, leading to toxicity.
* **Uricosuric Agents (e.g., probenecid):** Aspirin can reduce the efficacy of uricosuric agents.
* **Antihypertensives:** Aspirin may reduce the efficacy of some antihypertensive medications.
* **Alcohol:** Increased risk of GI irritation and bleeding.
## Monitoring
* **Bleeding:** Monitor for signs and symptoms of bleeding (e.g., bruising, hematemesis, melena).
* **GI Symptoms:** Assess for dyspepsia, abdominal pain, or other signs of gastric irritation.
* **Renal Function:** Monitor in patients with pre-existing renal disease or those at risk.
* **Liver Function:** Monitor in patients with liver disease or those on long-term, high-dose therapy.
* **Tinnitus/Hearing:** Assess for auditory changes, which may indicate toxicity.
## Clinical Pearls
* The enteric coating allows aspirin to pass through the stomach largely undissolved, reducing gastric irritation. However, it should still be swallowed whole and not crushed or chewed.
* For acute cardiovascular events (e.g., suspected MI), immediate administration of non-enteric coated aspirin (chewed) is often preferred for faster absorption.
* Patients should be advised to avoid alcohol while taking aspirin due to increased GI bleeding risk.
* Discontinue aspirin several days before elective surgery due to its antiplatelet effects.
* Reye's syndrome is a rare but serious condition; avoid aspirin in children and adolescents with viral illnesses.
