# Ecospirin Enteric-Coated (Aspirin)
## Overview
Ecospirin Enteric-Coated is a formulation of aspirin, a non-steroidal anti-inflammatory drug (NSAID) with analgesic, antipyretic, and antiplatelet properties. The enteric coating is designed to delay the dissolution of the tablet until it reaches the small intestine, which may reduce gastric irritation.
## Primary Indications
* Pain and fever
* Inflammatory conditions (e.g., rheumatoid arthritis)
* Prevention of cardiovascular events (e.g., myocardial infarction, stroke) in patients at risk
## Adult Dosing
Dosing varies significantly based on indication.
* **Analgesic/Antipyretic:** 325 mg to 650 mg every 4-6 hours as needed. Maximum daily dose typically 4000 mg.
* **Antiplatelet (Cardiovascular Prevention):** Common doses range from 75 mg to 325 mg once daily. Specific dosing for secondary prevention is often 81 mg or 325 mg daily. Dosing for primary prevention should be individualized based on risk assessment.
* **Inflammatory Conditions:** Higher doses may be used, typically starting at 2400 mg to 3600 mg per day in divided doses.
*Specific doses for cardiovascular prevention should align with current guidelines or local protocols.*
## Pediatric Dosing
**Aspirin should generally be avoided in children and teenagers with viral infections (including influenza and varicella) due to the risk of Reye's syndrome.**
When indicated for other conditions, doses are typically based on weight:
* **Analgesic/Antipyretic:** 10 mg/kg to 15 mg/kg per dose orally every 4 to 6 hours. Maximum pediatric dose is generally 650 mg per dose.
## Dose Adjustments
* **Renal Impairment:** Use with caution. Dose reduction may be necessary in severe renal impairment.
* **Hepatic Impairment:** Use with caution.
## Contraindications
* Known hypersensitivity to aspirin, salicylates, or NSAIDs.
* Active peptic ulceration or active gastrointestinal bleeding.
* History of bronchospasm, urticaria, or allergic-type reactions after taking salicylates or NSAIDs.
* Hemophilia or other bleeding disorders.
* In children and adolescents with viral infections (risk of Reye's syndrome).
## Adverse Effects
* **Gastrointestinal:** Dyspepsia, nausea, vomiting, abdominal pain, occult bleeding, peptic ulceration, GI perforation.
* **Hematologic:** Increased bleeding time, bruising, epistaxis.
* **Hypersensitivity:** Bronchospasm, urticaria, angioedema.
* **Ototoxicity:** Tinnitus, hearing loss (often with higher doses).
* **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 COX-2 Inhibitors:** Increased risk of GI toxicity, renal toxicity, and potential for reduced aspirin's cardioprotective effect.
* **Corticosteroids:** Increased risk of GI ulceration and bleeding.
* **Methotrexate:** Increased methotrexate toxicity.
* **Uricosuric agents (e.g., probenecid):** Decreased efficacy of uricosuric agent.
* **Alcohol:** Increased risk of GI bleeding.
* **Valproic acid:** Aspirin may displace valproic acid from protein-binding sites, increasing free valproic acid levels.
## Monitoring
* **Signs and symptoms of GI bleeding:** Melena, hematemesis, abdominal pain.
* **Bleeding:** Monitor for excessive bruising, prolonged bleeding from cuts, epistaxis.
* **Renal and hepatic function:** Especially in patients with pre-existing impairment or those on long-term therapy.
* **Tinnitus or hearing changes:** May indicate toxicity.
## Clinical Pearls
* The enteric coating may delay absorption but does not eliminate the risk of gastric irritation or bleeding, especially with higher doses or long-term use.
* For patients requiring daily low-dose aspirin for cardiovascular protection, taking it consistently is crucial.
* Always counsel patients on the risks of bleeding and advise them to report any signs of GI distress or unusual bleeding.
* Advise patients to avoid alcohol while taking aspirin.
