# Ecospirin (Aspirin Enteric-Coated)
## Overview
Ecospirin is an enteric-coated formulation of aspirin, a nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase (COX) enzymes. The enteric coating is designed to delay the dissolution of the tablet until it reaches the small intestine, potentially reducing gastric irritation.
## Primary Indications
* **Cardioprotection:** Prevention of myocardial infarction, stroke, and cardiovascular death in patients with established cardiovascular disease or risk factors.
* **Analgesia and Antipyresis:** Mild to moderate pain and fever (though less common with low-dose formulations).
* **Inflammation:** Inflammatory conditions (less common with low-dose formulations).
## Adult Dosing
* **Cardioprotection:** Typically 75 mg to 162 mg once daily. Higher doses may be used initially for acute events, followed by a lower maintenance dose. Specific dosing for acute coronary syndromes or post-PCI may vary based on institutional protocols.
* **Analgesia/Antipyresis:** Doses range from 325 mg to 650 mg every 4 to 6 hours as needed, not to exceed 4 grams daily.
* **Inflammation:** Doses can range from 2.6 grams to 5.4 grams per day, divided into multiple doses.
## Pediatric Dosing
* **Cardioprotection:** Not generally recommended for primary prevention in children.
* **Analgesia/Antipyresis:** Dosing is based on weight. Typical doses are 10 mg/kg to 15 mg/kg every 4 to 6 hours. **Avoid aspirin in children and adolescents with viral illnesses due to the risk of Reye's syndrome.**
## Dose Adjustments
* **Renal Impairment:** Use with caution. Dose reduction may be necessary in severe impairment.
* **Hepatic Impairment:** Use with caution. Monitor liver function.
## Contraindications
* Known hypersensitivity to aspirin, salicylates, NSAIDs, or tartrazine.
* History of bronchospasm, asthma, rhinitis, or urticaria induced by aspirin or other NSAIDs.
* Active peptic ulcer disease or gastrointestinal bleeding.
* Children and adolescents with viral infections (risk of Reye's syndrome).
* Third trimester of pregnancy.
## Adverse Effects
* **Gastrointestinal:** Dyspepsia, heartburn, nausea, vomiting, abdominal pain, occult bleeding, peptic ulceration, perforation.
* **Hematologic:** Increased bleeding time, bruising, epistaxis.
* **Hypersensitivity:** Bronchospasm, urticaria, angioedema.
* **Renal:** Acute kidney injury, interstitial nephritis.
* **Hepatic:** Elevated liver enzymes, hepatitis.
* **Other:** Tinnitus, hearing loss (especially with higher doses).
## Key Drug Interactions
* **Anticoagulants (e.g., warfarin, heparin, DOACs):** Increased risk of bleeding.
* **Other NSAIDs:** Increased risk of GI toxicity and reduced cardioprotective effect of aspirin.
* **Corticosteroids:** Increased risk of GI ulceration and bleeding.
* **Antihypertensives (e.g., ACE inhibitors, ARBs, beta-blockers):** NSAIDs may reduce their efficacy.
* **Methotrexate:** Increased methotrexate toxicity.
* **Uricosuric agents (e.g., probenecid):** Decreased efficacy.
* **Alcohol:** Increased risk of GI bleeding.
## Monitoring
* **Bleeding:** Monitor for signs of bleeding (e.g., melena, hematemesis, bruising).
* **Renal function:** Monitor creatinine and BUN, especially in patients with risk factors.
* **Liver function:** Monitor LFTs if hepatic impairment or significant side effects are suspected.
* **Tinnitus/Hearing:** Assess for symptoms of salicylate toxicity.
## Clinical Pearls
* The enteric coating delays absorption and may reduce gastric distress but does not eliminate the risk of GI bleeding, especially with chronic use.
* For cardioprotective indications, low-dose aspirin is generally preferred. Taking with food may help reduce gastric irritation.
* Discontinue aspirin at least 5-7 days before elective surgery, if possible, to reduce bleeding risk.
* Do not crush or chew enteric-coated aspirin tablets.
