# Ecospirin (Aspirin Enteric-Coated)
## Overview
Ecospirin is an enteric-coated formulation of aspirin, a nonsteroidal anti-inflammatory drug (NSAID) belonging to the salicylate class. The enteric coating is designed to delay the release of aspirin until it reaches the small intestine, which may reduce gastric irritation.
## Primary Indications
* **Cardiovascular prophylaxis:** Prevention of myocardial infarction and stroke in patients with established cardiovascular disease, or those at high risk.
* **Analgesia and antipyresis:** Mild to moderate pain and fever.
## Adult Dosing
* **Cardiovascular prophylaxis:**
* 81 mg to 325 mg once daily. The specific dose is often determined by local guidelines and individual patient risk assessment.
* **Analgesia/Antipyresis:**
* 325 mg to 650 mg every 4 to 6 hours as needed.
* Maximum daily dose typically 4000 mg.
## Pediatric Dosing
* **Fever/Pain:** Dosing is typically based on age and weight, but aspirin is generally **avoided in children and adolescents with viral infections** (e.g., influenza, varicella) due to the risk of Reye's syndrome. If used for other indications, dosing varies by condition. For example, in Kawasaki disease, doses may be higher (80-100 mg/kg/day divided into 4 doses) initially, then reduced to a low dose (3-5 mg/kg/day once daily). **Consult specific pediatric guidelines.**
## Dose Adjustments
* No specific dose adjustments are typically required for renal or hepatic impairment, but caution is advised, especially in severe dysfunction, due to potential for accumulation and increased adverse effects.
## Contraindications
* Hypersensitivity to aspirin, salicylates, or NSAIDs.
* History of asthma, urticaria, or allergic-type reactions induced by aspirin or NSAIDs.
* Active peptic ulcer disease.
* Bleeding disorders (e.g., hemophilia, thrombocytopenia).
* Severe hepatic or renal impairment.
* Concurrent use with anticoagulants (relative contraindication, use with extreme caution).
* Children and adolescents with viral illnesses (risk of Reye's syndrome).
## Adverse Effects
* **Gastrointestinal:** Dyspepsia, heartburn, nausea, vomiting, abdominal pain, gastritis, occult bleeding, peptic ulceration, perforation.
* **Hematologic:** Increased bleeding time, bruising, epistaxis, and in rare cases, severe hemorrhage.
* **Hypersensitivity:** Bronchospasm (especially in aspirin-sensitive asthmatics), urticaria, angioedema.
* **Other:** Tinnitus, dizziness, confusion, Reye's syndrome (in children/adolescents with viral infections).
## Key Drug Interactions
* **Anticoagulants (e.g., warfarin, heparin, DOACs):** Increased risk of bleeding.
* **Other NSAIDs and salicylates:** Increased risk of GI toxicity and bleeding.
* **Corticosteroids:** Increased risk of GI ulceration and bleeding.
* **Alcohol:** Increased risk of GI irritation and bleeding.
* **Methotrexate:** Aspirin can increase methotrexate toxicity by reducing its renal clearance.
* **Uricosuric agents (e.g., probenecid):** Aspirin antagonizes the uricosuric effect.
* **ACE inhibitors and ARBs:** May decrease antihypertensive effect and increase risk of renal impairment and bleeding.
* **SSRIs:** Increased risk of bleeding.
## Monitoring
* **Signs and symptoms of GI bleeding:** Melena, hematemesis, abdominal pain.
* **Signs and symptoms of bleeding:** Bruising, epistaxis, prolonged bleeding from cuts.
* **Renal and hepatic function:** Periodically, especially in patients with pre-existing impairment or those on long-term therapy.
* **Tinnitus:** May indicate overdosage.
## Clinical Pearls
* The enteric coating delays absorption but does not eliminate the risk of gastric side effects.
* For acute pain or fever, immediate-release aspirin may be preferred for faster onset of action.
* For cardiovascular prophylaxis, consistent daily dosing is crucial.
* Patients with known allergies to other NSAIDs should be cautioned about potential cross-reactivity.
* In cases of significant bleeding risk, alternative antiplatelet agents may be considered.
