# Ecospirin (Aspirin Enteric-Coated)
## Overview
Ecospirin is an enteric-coated formulation of aspirin, a nonsteroidal anti-inflammatory drug (NSAID) with analgesic, antipyretic, antiplatelet, and anti-inflammatory properties. The enteric coating is designed to prevent gastric irritation by delaying the dissolution of the tablet until it reaches the small intestine.
## Primary Indications
* Pain and inflammation associated with conditions like arthritis.
* Prevention of cardiovascular events (e.g., myocardial infarction, stroke) in patients with established cardiovascular disease or risk factors.
* Management of Kawasaki disease.
## Adult Dosing
Dosing varies significantly based on indication.
* **Pain/Inflammation:** 325 mg to 650 mg every 4 to 6 hours as needed, not to exceed 4 g per day. For chronic inflammatory conditions, doses may range from 2.6 g to 5.4 g per day, divided into 4 to 6 doses.
* **Cardiovascular Prevention (Primary/Secondary):** Doses typically range from 75 mg to 325 mg once daily. Specific dosing is guided by established guidelines and patient risk.
## Pediatric Dosing
* **Kawasaki Disease:** Initial dose: 80 to 100 mg/kg/day divided into 4 doses. Following defervescence, the dose is typically reduced to 3 to 5 mg/kg/day once daily. Duration of therapy depends on clinical response and guidelines.
* **Pain/Inflammation:** Generally avoided in children and adolescents due to the risk of Reye's syndrome.
## Dose Adjustments
No specific dose adjustments are typically required for hepatic or renal impairment, but caution is advised. Use in patients with severe hepatic or renal disease is generally discouraged.
## Contraindications
* Known hypersensitivity to aspirin, salicylates, or NSAIDs.
* Asthma, urticaria, or allergic-type reactions after taking aspirin or other NSAIDs.
* In children and adolescents with viral infections due to the risk of Reye's syndrome.
* Bleeding disorders.
* Active peptic ulcer disease or recent gastrointestinal bleeding.
## Adverse Effects
* **Gastrointestinal:** Dyspepsia, heartburn, nausea, vomiting, abdominal pain, gastritis, peptic ulceration, GI bleeding.
* **Hematologic:** Increased bleeding time, bruising, petechiae.
* **Hypersensitivity:** Bronchospasm, urticaria, angioedema, rash.
* **Other:** Tinnitus, hearing loss (especially at higher doses), dizziness, confusion.
## Key Drug Interactions
* **Anticoagulants (e.g., warfarin, heparin, DOACs):** Increased risk of bleeding.
* **Other NSAIDs (including COX-2 inhibitors):** Increased risk of GI toxicity and reduced cardioprotective effects of aspirin.
* **Corticosteroids:** Increased risk of GI ulceration and bleeding.
* **Alcohol:** Increased risk of GI irritation and bleeding.
* **Methotrexate:** Aspirin may increase methotrexate toxicity.
* **Antihypertensives (e.g., ACE inhibitors, ARBs, diuretics):** NSAIDs can decrease their efficacy and increase risk of renal impairment.
## Monitoring
* **Signs and symptoms of GI bleeding** (e.g., melena, hematemesis, abdominal pain).
* **Signs and symptoms of bleeding** elsewhere (e.g., bruising, epistaxis).
* **Renal function** in patients with risk factors or prolonged use.
* **Auditory symptoms** (tinnitus) may indicate toxicity.
## Clinical Pearls
* The enteric coating should not be crushed or chewed to maintain its protective properties.
* Patients should be advised to take with food or milk to minimize gastric upset, even with enteric coating.
* Due to the risk of Reye's syndrome, aspirin should be avoided in children and teenagers with fever or flu-like symptoms unless specifically recommended by a healthcare provider.
* The antiplatelet effect of aspirin is irreversible and lasts for the life of the platelet (7-10 days).
