# Ecospirin Enteric-Coated (Aspirin)
## Overview
Ecospirin Enteric-Coated is a formulation of aspirin (acetylsalicylic acid), 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
* **Analgesia and Antipyresis:** For mild to moderate pain and fever.
* **Antiplatelet Therapy:** Prevention of cardiovascular events (e.g., myocardial infarction, stroke) in patients with established cardiovascular disease or at high risk.
* **Rheumatic Fever Prophylaxis:** Treatment and prevention of rheumatic fever.
## Adult Dosing
* **Analgesia/Antipyresis:** 325 mg to 650 mg every 4 to 6 hours as needed. Maximum daily dose typically 4000 mg.
* **Cardiovascular Prevention (Primary/Secondary):** 75 mg to 100 mg once daily (lower doses are often preferred for chronic use to minimize bleeding risk).
* **Rheumatic Fever:** 60 mg/kg/day divided into 4 doses. Higher doses may be required for carditis.
Dosing for specific indications, especially cardiovascular prevention, may vary based on institutional guidelines and patient-specific factors.
## Pediatric Dosing
* **Analgesia/Antipyresis:** 10 mg/kg/dose to 15 mg/kg/dose every 4 to 6 hours. Maximum daily dose 60 mg/kg/day or 4000 mg, whichever is less.
* **Kawasaki Disease:** High-dose aspirin therapy (80-100 mg/kg/day divided into 4 doses) is used during the acute phase, followed by low-dose aspirin (3-5 mg/kg/day once daily) after fever subsides.
**Note:** Aspirin should generally be avoided in children and adolescents with viral illnesses due to the risk of Reye's syndrome.
## 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.
* Children and adolescents with viral infections (risk of Reye's syndrome).
* Active peptic ulcer disease or gastrointestinal bleeding.
* Severe hepatic impairment.
* Severe renal impairment.
* Third trimester of pregnancy.
* Hemophilia or other bleeding disorders.
## Adverse Effects
* **Gastrointestinal:** Dyspepsia, nausea, vomiting, abdominal pain, GI bleeding, ulceration.
* **Hematologic:** Increased bleeding time, bruising.
* **Hypersensitivity:** Bronchospasm (especially in aspirin-sensitive asthmatics), urticaria, angioedema.
* **Otic:** Tinnitus, hearing loss (especially at higher doses).
* **Renal:** Acute kidney injury, interstitial nephritis.
* **Reye's Syndrome:** In children/adolescents with viral illnesses.
## Key Drug Interactions
* **Anticoagulants (e.g., warfarin, heparin, DOACs):** Increased risk of bleeding.
* **Other NSAIDs and COX-2 Inhibitors:** Increased risk of GI bleeding and reduced cardioprotective effects of low-dose aspirin.
* **Corticosteroids:** Increased risk of GI ulceration and bleeding.
* **Antihypertensives (e.g., ACE inhibitors, ARBs, diuretics):** May reduce antihypertensive efficacy and increase risk of renal impairment.
* **Methotrexate:** Increased methotrexate toxicity.
* **Uricosuric agents (e.g., probenecid):** Reduced efficacy of uricosuric agent.
* **Alcohol:** Increased risk of GI bleeding.
## Monitoring
* **GI Bleeding:** Monitor for signs and symptoms (e.g., melena, hematemesis, abdominal pain).
* **Bleeding Risk:** Monitor for bruising, prolonged bleeding from cuts.
* **Renal Function:** Particularly in patients with pre-existing renal disease, dehydration, or concomitant nephrotoxic agents.
* **Hepatic Function:** In patients with hepatic impairment or receiving long-term therapy.
* **Tinnitus/Hearing:** Assess for signs of salicylism, especially at higher doses.
## Clinical Pearls
* The enteric coating reduces gastric irritation but does not eliminate the risk of GI bleeding.
* For acute cardiovascular event prevention, aspirin should be given immediately as per emergency protocols (often non-enteric coated for faster absorption).
* Low-dose aspirin (75-100 mg daily) is typically used for chronic antiplatelet therapy.
* Avoid concomitant use with other NSAIDs unless absolutely necessary and with extreme caution.
* Discontinue aspirin several days prior to elective surgery to minimize bleeding risk.
