# 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 absorption of aspirin until it reaches the small intestine, potentially reducing gastric irritation.
## Primary Indications
* Pain and inflammation (e.g., musculoskeletal pain, headaches, dysmenorrhea)
* Fever
* Prevention of cardiovascular events (e.g., myocardial infarction, stroke) in specific patient populations.
## Adult Dosing
* **Pain/Fever/Inflammation:**
* Typical doses range from 325 mg to 650 mg orally every 4 to 6 hours as needed.
* Maximum daily dose is generally 4000 mg.
* **Cardiovascular Prevention (Antiplatelet):**
* **Primary Prevention:** Low-dose aspirin (e.g., 81 mg to 325 mg once daily) may be considered in select individuals based on a risk-benefit assessment. This is not universally recommended.
* **Secondary Prevention:** Typically 81 mg to 325 mg orally once daily. Higher doses may be used in the acute phase of certain cardiovascular events (e.g., acute coronary syndrome). Dosing in these acute settings should follow specific guidelines and physician orders.
## Pediatric Dosing
* **Pain/Fever/Inflammation:** Dosing is based on weight: 10 mg/kg/dose to 15 mg/kg/dose orally every 4 to 6 hours.
* Maximum daily dose is typically 60 mg/kg, not to exceed the adult maximum of 4000 mg.
* **Important Note:** Aspirin should be avoided in children and teenagers with viral infections (e.g., influenza, chickenpox) due to the risk of Reye's syndrome.
## Dose Adjustments
* **Renal Impairment:** Use with caution. Dose reduction may be necessary in severe renal impairment.
* **Hepatic Impairment:** Use with caution.
* **Elderly:** Increased risk of GI bleeding and other adverse effects; consider lower doses and closer monitoring.
## Contraindications
* Known hypersensitivity to aspirin, salicylates, NSAIDs, or any component of the formulation.
* History of aspirin-induced asthma, urticaria, or allergic-type reactions.
* Active peptic ulceration or recent gastrointestinal bleeding.
* Certain bleeding disorders (e.g., hemophilia, thrombocytopenia).
* Severe renal or hepatic impairment.
* Children and teenagers with viral infections.
## Adverse Effects
* **Gastrointestinal:** Dyspepsia, heartburn, nausea, vomiting, abdominal pain, occult blood loss, GI ulceration, perforation, and bleeding (risk increased with dose and duration).
* **Hematologic:** Increased bleeding time, bruising, petechiae, prolonged prothrombin time.
* **Hypersensitivity:** Bronchospasm (especially in aspirin-sensitive asthma), urticaria, angioedema.
* **Other:** Tinnitus, dizziness, headache, Reye's syndrome (in children/adolescents with viral illness).
## 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 reduced cardioprotective effect of aspirin.
* **Corticosteroids:** Increased risk of GI ulceration and bleeding.
* **Antihypertensives (e.g., ACE inhibitors, ARBs, beta-blockers):** NSAIDs may diminish their antihypertensive effect and increase the risk of renal impairment.
* **Diuretics:** NSAIDs may reduce their diuretic and natriuretic effect and increase the risk of renal impairment.
* **Methotrexate:** Aspirin can decrease methotrexate clearance and increase toxicity.
* **Uricosuric agents (e.g., probenecid):** Aspirin can interfere with the uricosuric effect.
* **Selective Serotonin Reuptake Inhibitors (SSRIs):** Increased risk of bleeding, particularly GI bleeding.
## Monitoring
* **Signs of GI bleeding:** Melena, hematemesis, abdominal pain.
* **Bleeding:** Monitor for bruising, epistaxis, prolonged bleeding from cuts.
* **Renal function:** Especially in patients with pre-existing renal disease or those at risk.
* **Hepatic function:** If liver disease is present.
* **Tinnitus:** May indicate salicylate toxicity.
## Clinical Pearls
* The enteric coating does not eliminate the risk of GI bleeding entirely, especially with chronic use or in high-risk individuals.
* For acute antiplatelet therapy, non-enteric coated aspirin is often preferred for faster absorption.
* Ensure adequate hydration.
* Avoid concomitant use with other NSAIDs unless specifically indicated and managed.
* Inquire about allergies to NSAIDs, especially aspirin.
