# 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 protect the stomach lining from direct irritation and to delay absorption until the drug reaches the small intestine.
## Primary Indications
* **Cardiovascular prophylaxis:** Prevention of myocardial infarction and stroke in patients with established cardiovascular disease, or at high risk.
* **Analgesia and antipyresis:** Mild to moderate pain and fever.
* **Inflammation:** Rheumatic conditions.
## Adult Dosing
* **Cardiovascular prophylaxis:** Typically 75 mg to 162 mg once daily. Lower doses (e.g., 75-100 mg) are often preferred for long-term prevention to minimize bleeding risk.
* **Analgesia/Antipyresis:** 325 mg to 1000 mg every 4-6 hours as needed. Maximum daily dose generally 4000 mg.
* **Inflammation:** 2000 mg to 4000 mg per day in divided doses.
*Note: Dosing for cardiovascular prophylaxis often follows specific clinical guidelines; consult local protocols.*
## Pediatric Dosing
Aspirin is generally **contraindicated** in children and adolescents with viral infections due to the risk of Reye's syndrome. Limited specific dosing is established for pediatric use due to this risk.
## Dose Adjustments
No specific dose adjustments are typically required for renal or hepatic impairment, but caution is advised due to potential for accumulation and increased toxicity, especially in severe impairment.
## Contraindications
* Known hypersensitivity to aspirin, salicylates, NSAIDs, or any component of the formulation.
* Children and adolescents with viral infections (risk of Reye's syndrome).
* Active peptic ulcer disease or history of gastrointestinal bleeding.
* Bleeding disorders.
* Severe hepatic or renal impairment.
* Severe heart failure.
* Third trimester of pregnancy.
## Adverse Effects
* **Gastrointestinal:** Dyspepsia, nausea, vomiting, abdominal pain, heartburn, gastritis, GI bleeding, perforation.
* **Hematologic:** Increased bleeding tendency, bruising, epistaxis, prolonged bleeding time.
* **Hypersensitivity:** Bronchospasm, urticaria, angioedema, anaphylaxis.
* **Renal:** Acute kidney injury, interstitial nephritis.
* **Hepatic:** Hepatotoxicity.
* **Other:** Tinnitus, hearing loss, Reye's syndrome (in children/adolescents).
## Key Drug Interactions
* **Anticoagulants (e.g., warfarin, heparin, DOACs):** Increased risk of bleeding.
* **Other NSAIDs and COX-2 inhibitors:** Additive GI toxicity and increased bleeding risk.
* **Corticosteroids:** Increased risk of GI ulceration and bleeding.
* **Selective Serotonin Reuptake Inhibitors (SSRIs):** Increased risk of bleeding.
* **Methotrexate:** Increased methotrexate toxicity.
* **Uricosuric agents (e.g., probenecid):** Reduced efficacy of uricosuric agents.
* **Alcohol:** Increased risk of GI irritation and bleeding.
## Monitoring
* **Signs of GI bleeding:** Melena, hematochezia, hematemesis, abdominal pain.
* **Signs of bleeding:** Bruising, epistaxis, prolonged bleeding from cuts.
* **Renal function:** Especially in patients with pre-existing renal disease or those on concomitant nephrotoxic agents.
* **Hepatic function:** Especially with long-term or high-dose therapy.
* **Tinnitus/hearing changes:** May indicate salicylate toxicity.
## Clinical Pearls
* The enteric coating delays absorption but does not eliminate the risk of GI irritation or bleeding, especially with long-term use or in susceptible individuals.
* Do not crush or chew enteric-coated aspirin; it must be swallowed whole.
* For acute pain or fever, immediate-release aspirin may provide faster relief. Enteric-coated aspirin is primarily for chronic use or when GI protection is prioritized.
* In patients requiring urgent antiplatelet therapy (e.g., acute coronary syndrome), immediate-release non-enteric-coated aspirin is preferred for faster onset of action.
