# Ecospirin (Aspirin, Enteric-Coated)
## Overview
Ecospirin is an enteric-coated formulation of aspirin, a nonsteroidal anti-inflammatory drug (NSAID) that functions as an antiplatelet agent. The enteric coating is designed to delay absorption and reduce gastric irritation.
## Primary Indications
* **Cardiovascular risk reduction:** Primary and secondary prevention of myocardial infarction and stroke.
* **Analgesia and anti-inflammatory:** Mild to moderate pain and inflammatory conditions. (Note: Lower doses are typically used for antiplatelet effects).
## Adult Dosing
* **Cardiovascular prophylaxis:** Commonly 75 mg to 100 mg once daily. Higher doses like 325 mg may be used in specific secondary prevention scenarios or as directed by guidelines.
* **Analgesia/Anti-inflammatory:** Typically 325 mg to 650 mg every 4-6 hours as needed. Maximum daily dose: 4000 mg.
## Pediatric Dosing
Aspirin is generally **not recommended** for use in children and adolescents due to the risk of Reye's syndrome, particularly when used for fever or viral illnesses. Specific indications under strict medical supervision (e.g., Kawasaki disease) should follow specialized pediatric guidelines.
## Dose Adjustments
No specific dose adjustments are typically required for hepatic or renal impairment, but caution is advised, especially in severe disease, due to potential for adverse effects.
## Contraindications
* Hypersensitivity to aspirin, salicylates, NSAIDs, or any component of the formulation.
* Active peptic ulcer disease or history of gastrointestinal bleeding.
* Bleeding disorders.
* Severe hepatic or renal impairment.
* Children and teenagers with viral infections (due to risk of Reye's syndrome).
* Concurrent use of NSAIDs or anticoagulants may increase bleeding risk.
## Adverse Effects
* **Gastrointestinal:** Dyspepsia, nausea, vomiting, abdominal pain, GI bleeding, ulceration.
* **Hematologic:** Increased bleeding time, bruising, petechiae, epistaxis.
* **Hypersensitivity:** Bronchospasm (especially in asthmatics with nasal polyps), urticaria, angioedema.
* **Other:** Tinnitus, dizziness, headache.
## 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.
* **Alcohol:** Increased risk of GI irritation and bleeding.
* **Methotrexate:** Aspirin can increase methotrexate toxicity.
* **Uricosuric agents (e.g., probenecid):** Aspirin may impair the uricosuric effect.
* **Antihypertensives/Diuretics:** Aspirin may reduce efficacy.
## Monitoring
* **Bleeding:** Monitor for signs and symptoms of bleeding (e.g., melena, hematemesis, bruising, prolonged bleeding from cuts).
* **GI Symptoms:** Assess for dyspepsia, abdominal pain.
* L* **Renal function:** Particularly in patients with pre-existing renal disease or those on concomitant nephrotoxic agents.
* * **Hearing:** Tinnitus may indicate salicylate toxicity.
## Clinical Pearls
* Enteric coating delays absorption but does not eliminate gastric risk entirely, particularly with prolonged use or in susceptible individuals. Do not crush or chew enteric-coated aspirin.
* For acute situations requiring rapid antiplatelet effect or higher doses, immediate-release aspirin formulations are preferred.
* Discontinue aspirin at least 5-7 days prior to elective surgery, if clinically permissible.
* Cessation of aspirin for non-urgent reasons, particularly in secondary prevention, requires careful risk-benefit assessment due to potential for rebound thrombotic events.
