# 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 absorption and reduce gastric irritation.
## Primary Indications
* **Cardiovascular Prevention:** Prevention of myocardial infarction (MI), stroke, and cardiovascular death in patients with established cardiovascular disease or at high risk.
* **Analgesic/Antipyretic:** Relief of mild to moderate pain and fever. (Note: Higher doses are typically required for these indications compared to antiplatelet therapy, and non-enteric coated formulations are often preferred for faster onset).
## Adult Dosing
* **Cardiovascular Prevention:**
* **Primary Prevention:** 75 mg to 100 mg once daily. Decision should be individualized based on risk assessment.
* **Secondary Prevention:** 75 mg to 325 mg once daily.
* **Analgesic/Antipyretic:** 325 mg to 650 mg every 4 to 6 hours as needed. Maximum daily dose generally 4000 mg. However, for antiplatelet therapy, the dose is typically much lower and administered daily.
## Pediatric Dosing
Aspirin is generally **not recommended** for use in children and adolescents under 18 years of age for fever or viral illnesses due to the risk of Reye's syndrome. Specific dosing for pediatric indications, if any, would be highly specialized and typically managed by a pediatric specialist.
## Dose Adjustments
No specific adjustments are generally required for renal or hepatic impairment with low-dose aspirin for cardiovascular indications. However, caution is advised in severe impairment, and higher doses for other indications may require adjustments.
## Contraindications
* Known hypersensitivity to aspirin, salicylates, NSAIDs, or any component of the formulation.
* Asthma, urticaria, or allergic-type reactions precipitated by aspirin or other NSAIDs.
* Active peptic ulcer disease or gastrointestinal bleeding.
* In children and adolescents with viral infections (influenza or varicella) due to the risk of Reye's syndrome.
* Hemophilia or other hemorrhagic diatheses.
## Adverse Effects
* **Gastrointestinal:** Dyspepsia, heartburn, nausea, vomiting, abdominal pain, gastritis, ulceration, bleeding.
* **Hematologic:** Increased bleeding time, bruising, epistaxis, menorrhagia.
* **Hypersensitivity:** Bronchospasm, urticaria, angioedema.
* **Other:** Tinnitus (especially at higher doses), dizziness.
## Key Drug Interactions
* **Anticoagulants (e.g., warfarin, heparin, DOACs):** Increased risk of bleeding. Concurrent use requires careful monitoring.
* **Other NSAIDs and Salicylates:** Increased risk of GI toxicity and reduced antiplatelet effect of aspirin.
* **Corticosteroids:** Increased risk of GI ulceration and bleeding.
* **Selective Serotonin Reuptake Inhibitors (SSRIs):** Increased risk of bleeding.
* **Methotrexate:** Increased methotrexate toxicity.
* **Antihypertensives (e.g., ACE inhibitors, ARBs, diuretics):** May reduce antihypertensive efficacy and increase risk of renal dysfunction; potential synergy for bleeding.
* **Uricosuric agents (e.g., probenecid):** Aspirin may decrease the efficacy of uricosuric agents.
## Monitoring
* **Bleeding signs and symptoms:** Monitor for bruising, prolonged bleeding from cuts, hematemesis, melena.
* **GI discomfort:** Assess for symptoms of indigestion, pain, or heartburn.
* **Renal function:** In patients with pre-existing renal disease or receiving concurrent nephrotoxic agents.
* **Tinnitus:** Can be an early sign of salicylism, particularly at higher doses.
## Clinical Pearls
* The enteric coating aims to protect the stomach lining, but significant GI bleeding can still occur.
* For acute cardiovascular events (e.g., suspected MI), non-enteric coated chewable aspirin is often preferred for rapid absorption.
* Patients should be advised to avoid alcohol while taking aspirin due to increased GI irritation and bleeding risk.
* Discontinue aspirin at least 5-7 days prior to elective surgery, if feasible, after consulting with the prescribing physician.
