# Ecospirin Enteric-Coated (Aspirin)
## Overview
Ecospirin is an enteric-coated formulation of aspirin, a non-steroidal anti-inflammatory drug (NSAID) that possesses analgesic, anti-inflammatory, and antipyretic properties. The enteric coating is designed to protect the stomach lining from irritation and to delay the absorption of aspirin until it reaches the small intestine.
## Primary Indications
* Pain relief (mild to moderate)
* Fever reduction
* Inflammation reduction
* Prophylaxis of cardiovascular events (e.g., myocardial infarction, stroke) in specific patient populations.
## Adult Dosing
Dosing is highly variable and depends on the indication.
* **Analgesia/Antipyresis:** 325 mg to 650 mg every 4 to 6 hours as needed. Maximum daily dose typically not to exceed 4000 mg.
* **Cardiovascular Prophylaxis:** Typically 75 mg to 162 mg once daily.
## Pediatric Dosing
Aspirin is generally **not recommended** for use in children and teenagers due to the risk of Reye's syndrome, a rare but serious illness.
## Dose Adjustments
* **Renal Impairment:** Use with caution. Dose reduction may be necessary in severe impairment.
* **Hepatic Impairment:** Use with caution.
## Contraindications
* Hypersensitivity to aspirin, salicylates, or NSAIDs.
* History of aspirin-induced asthma or urticaria.
* Active peptic ulceration or gastrointestinal bleeding.
* Certain bleeding disorders (e.g., hemophilia).
* Severe renal or hepatic impairment.
* Children and teenagers with viral infections (risk of Reye's syndrome).
## Adverse Effects
* **Gastrointestinal:** Dyspepsia, nausea, vomiting, abdominal pain, heartburn, occult or overt GI bleeding, ulceration.
* **Hematologic:** Increased bleeding time, bruising, epistaxis.
* **Hypersensitivity:** Bronchospasm, urticaria, angioedema, anaphylaxis.
* **Ototoxicity:** Tinnitus, hearing loss (typically with higher doses).
* **Renal:** Sodium and water retention, renal impairment.
* **Reye's Syndrome:** In children and teenagers with viral infections.
## Key Drug Interactions
* **Anticoagulants (e.g., warfarin, heparin):** Increased risk of bleeding.
* **Other NSAIDs and COX-2 Inhibitors:** Increased risk of GI toxicity, potential for reduced aspirin cardioprotective effect.
* **Corticosteroids:** Increased risk of GI ulceration.
* **Methotrexate:** Increased methotrexate toxicity.
* **Antihypertensives (e.g., ACE inhibitors, ARBs, diuretics):** Reduced antihypertensive effect, increased risk of renal dysfunction.
* **Antacids:** May decrease absorption of enteric-coated aspirin. Separate administration.
* **Alcohol:** Increased risk of GI bleeding.
## Monitoring
* Signs and symptoms of GI bleeding (e.g., melena, hematemesis, abdominal pain).
* Signs of bleeding (e.g., bruising, epistaxis).
* Renal and hepatic function, especially with prolonged use or in patients with underlying impairment.
* Hearing, particularly with higher doses.
## Clinical Pearls
* The enteric coating delays absorption; do not crush or chew enteric-coated tablets, as this will destroy the coating and increase the risk of gastric irritation.
* Patients taking aspirin for cardiovascular prophylaxis should be advised to take it consistently as directed.
* Due to the increased risk of bleeding, aspirin should be discontinued several days before elective surgery.
* For pain and fever, consider acetaminophen as an alternative in patients with contraindications or intolerance to aspirin.
