# 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 the release of aspirin until it reaches the small intestine, potentially reducing gastric irritation.
## Primary Indications
* **Cardiovascular prophylaxis:** Prevention of myocardial infarction, stroke, and vascular death in patients with established atherosclerotic cardiovascular disease or at high risk.
* **Pain and inflammation:** Relief of mild to moderate pain and reduction of fever (less commonly used for these indications due to gastrointestinal risks and availability of safer alternatives).
* **Rheumatic fever prophylaxis:** Prevention of recurrence.
## Adult Dosing
* **Cardiovascular prophylaxis:** Typically 75 mg to 150 mg once daily. Doses of 81 mg or 100 mg are common.
* **Pain and inflammation:** Doses vary widely. For mild to moderate pain, 325 mg to 650 mg every 4 to 6 hours as needed. Maximum daily dose typically 4000 mg.
* **Rheumatic fever prophylaxis:** 75 mg to 100 mg once daily, or higher doses in acute inflammatory phases.
## Pediatric Dosing
* **Rheumatic fever prophylaxis:** Generally 75 mg to 100 mg once daily.
* **Inflammatory conditions (e.g., Kawasaki disease):** Dosing varies significantly by indication and phase of illness, often requiring higher doses initially followed by low-dose maintenance. Consult specific pediatric guidelines.
* **Fever/Pain:** Aspirin is generally **not recommended** for children and adolescents due to the risk of Reye's syndrome, especially during viral illnesses.
## Dose Adjustments
No specific dose adjustments are typically required for hepatic or renal impairment, but caution is advised, especially with higher doses or prolonged use.
## Contraindications
* Known hypersensitivity to aspirin or NSAIDs.
* Active gastrointestinal bleeding or peptic ulcer disease.
* Bleeding disorders.
* Severe hepatic or renal impairment.
* Children and adolescents with viral infections (risk of Reye's syndrome).
## Adverse Effects
Common adverse effects include gastrointestinal upset, heartburn, nausea, and dyspepsia. More serious effects include gastrointestinal bleeding, ulceration, tinnitus (ringing in the ears), bronchospasm (especially in asthmatics), and hypersensitivity reactions. Reye's syndrome in children is a significant risk.
## Key Drug Interactions
* **Anticoagulants (e.g., warfarin, DOACs):** Increased risk of bleeding.
* **Other NSAIDs and salicylates:** Increased risk of gastrointestinal toxicity and bleeding.
* **Corticosteroids:** Increased risk of gastrointestinal ulceration and bleeding.
* **Selective serotonin reuptake inhibitors (SSRIs):** Increased risk of bleeding.
* **Methotrexate:** Aspirin can increase methotrexate toxicity.
* **Antihypertensives (e.g., ACE inhibitors, diuretics):** May reduce their efficacy.
## Monitoring
* Monitor for signs and symptoms of gastrointestinal bleeding (e.g., melena, hematemesis, abdominal pain).
* Monitor for tinnitus or hearing changes, which may indicate salicylate toxicity.
* Monitor for signs of hypersensitivity reactions.
## Clinical Pearls
* The enteric coating reduces but does not eliminate the risk of gastrointestinal side effects.
* For acute pain relief, immediate-release aspirin may be preferred if gastrointestinal tolerance is not a primary concern.
* Due to the risk of Reye's syndrome, aspirin should be avoided in children and adolescents with febrile illnesses.
