# 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 delay dissolution until the drug reaches the small intestine, which may reduce gastric irritation.
## Primary Indications
* Pain relief (mild to moderate)
* Fever reduction
* Inflammation reduction
* Prevention of cardiovascular events (e.g., myocardial infarction, stroke) in certain high-risk individuals.
## Adult Dosing
* **Pain/Fever/Inflammation:** Typically 325 mg to 650 mg every 4 to 6 hours as needed. Maximum daily dose generally not to exceed 4000 mg. Doses may vary based on specific condition and physician guidance.
* **Cardiovascular Prevention:**
* Primary prevention: 75 mg to 100 mg once daily (lower doses preferred to minimize bleeding risk).
* Secondary prevention: 75 mg to 325 mg once daily.
* Higher doses (e.g., 325 mg) may be used acutely after cardiovascular events.
## Pediatric Dosing
Aspirin is generally **not recommended** for children and teenagers due to the risk of Reye's syndrome, a rare but serious illness, when used during viral infections like influenza or chickenpox.
## Dose Adjustments
* **Hepatic Impairment:** Use with caution; may require dose reduction.
* **Renal Impairment:** Use with caution; may require dose reduction, especially in severe impairment.
## Contraindications
* Known hypersensitivity to aspirin, salicylates, or NSAIDs.
* History of asthma, urticaria, or other allergic-type reactions after taking aspirin or other NSAIDs.
* Active peptic ulcer disease or gastrointestinal bleeding.
* Children and teenagers with viral infections.
* Certain bleeding disorders.
## Adverse Effects
Common: Nausea, vomiting, heartburn, dyspepsia, rash.
Serious: Gastrointestinal bleeding, ulceration, perforation, tinnitus, hearing loss, bronchospasm, anaphylaxis, Reye's syndrome (in children/teenagers with viral infections), renal impairment.
## Key Drug Interactions
* **Anticoagulants (e.g., warfarin, heparin, DOACs):** Increased risk of bleeding.
* **Other NSAIDs:** Increased risk of GI toxicity and bleeding.
* **Corticosteroids:** Increased risk of GI ulceration and bleeding.
* **Selective Serotonin Reuptake Inhibitors (SSRIs):** Increased risk of bleeding, particularly in the GI tract.
* **Methotrexate:** Aspirin can increase methotrexate toxicity.
* **Antihypertensives (e.g., ACE inhibitors, ARBs, diuretics):** Reduced antihypertensive effect and increased risk of renal dysfunction.
* **Valproic acid:** Aspirin can displace valproic acid from protein binding sites, increasing serum levels and toxicity.
## Monitoring
* Signs and symptoms of GI bleeding (e.g., black tarry stools, hematemesis).
* Signs of tinnitus or hearing loss.
* Renal function (especially in patients with pre-existing renal disease or those on concomitant nephrotoxic agents).
* Platelet function if antiplatelet effects are critical and monitoring is available.
## Clinical Pearls
* The enteric coating is intended to bypass the stomach; therefore, do not crush, chew, or break the tablets.
* Aspirin's antiplatelet effect is irreversible and lasts for the life of the platelet (7-10 days).
* Concomitant use of proton pump inhibitors (PPIs) or H2 blockers may be considered in patients at high risk for GI events when aspirin is used for cardiovascular protection.
* Inform patients to avoid alcohol while taking aspirin due to increased risk of GI bleeding.
