# Ecospirin (Aspirin Enteric-Coated)
## Overview
Ecospirin is an enteric-coated formulation of aspirin, a nonsteroidal anti-inflammatory drug (NSAID) and antiplatelet agent. The enteric coating is designed to prevent dissolution in the stomach, releasing the medication in the small intestine, which may reduce gastric irritation.
## Primary Indications
* Pain relief (analgesic)
* Inflammation reduction (anti-inflammatory)
* Fever reduction (antipyretic)
* Prevention of cardiovascular events (e.g., myocardial infarction, stroke) in specific patient populations.
## Adult Dosing
Dosing varies significantly based on indication.
* **Analgesic/Antipyretic/Anti-inflammatory:** Typically 325 mg to 650 mg every 4 to 6 hours as needed. Maximum daily dose generally not to exceed 4000 mg, though lower maximums are often recommended for long-term use.
* **Cardiovascular Prevention:** Doses are often lower. Common doses include 75 mg to 100 mg once daily for primary and secondary prevention. Higher doses (e.g., 325 mg daily) may be used in specific acute settings like post-myocardial infarction or percutaneous coronary intervention, as per institutional protocols.
## Pediatric Dosing
Aspirin is generally **contraindicated** in children and adolescents for viral infections or febrile illnesses due to the risk of Reye's syndrome. For other indications where aspirin may be considered in pediatric patients, dosing should be guided by specific clinical guidelines and physician judgment, typically based on weight. Precise, universally established pediatric doses for all indications are not provided here due to the contraindication and variability.
## Dose Adjustments
No specific dose adjustments are typically required for renal or hepatic impairment unless severe. However, caution is advised in patients with mild to moderate impairment, and the lowest effective dose should be used.
## Contraindications
* Known hypersensitivity to aspirin, salicylates, NSAIDs, or any component of the formulation.
* Active peptic ulceration or history of recurrent gastrointestinal (GI) bleeding.
* Severe hepatic impairment.
* Severe renal impairment.
* Bleeding disorders.
* Use in children and adolescents with viral infections or febrile illnesses (risk of Reye's syndrome).
* Third trimester of pregnancy.
## Adverse Effects
Common adverse effects include GI upset, nausea, vomiting, heartburn, and dyspepsia. More serious effects include GI bleeding, ulceration, hypersensitivity reactions (including bronchospasm, urticaria), tinnitus, and increased bleeding risk.
## Key Drug Interactions
* **Anticoagulants (e.g., warfarin, heparin, DOACs):** Increased risk of bleeding.
* **Other NSAIDs and COX-2 Inhibitors:** Increased risk of GI toxicity and bleeding.
* **Corticosteroids:** Increased risk of GI ulceration and bleeding.
* **Selective Serotonin Reuptake Inhibitors (SSRIs):** Increased risk of bleeding.
* **Methotrexate:** Aspirin can increase methotrexate toxicity.
* **Uricosuric agents (e.g., probenecid):** Aspirin may reduce the efficacy of uricosuric agents.
* **Alcohol:** Increased risk of GI irritation and bleeding.
## Monitoring
* Monitor for signs and symptoms of GI bleeding (e.g., melena, hematemesis, abdominal pain).
* Monitor for signs of hypersensitivity reactions.
* Monitor for tinnitus, which may indicate toxicity.
* For patients on long-term therapy for cardiovascular prevention, monitor for bleeding events.
* In patients with renal impairment, monitor renal function.
## Clinical Pearls
* The enteric coating is intended to delay absorption and reduce gastric irritation. Tablets should be swallowed whole and not crushed, chewed, or broken.
* The risk of GI bleeding is present even with enteric-coated formulations, especially at higher doses or with prolonged use.
* Aspirin is not typically used for fever in children due to the risk of Reye's syndrome.
* Patients should be advised to avoid alcohol while taking aspirin to minimize GI risk.
