# Ecospirin (Aspirin Enteric-Coated)
## Overview
Ecospirin is an enteric-coated formulation of aspirin, a nonsteroidal anti-inflammatory drug (NSAID) of the salicylate class. The enteric coating is designed to delay the absorption of aspirin until it reaches the small intestine, potentially reducing gastrointestinal irritation.
## Primary Indications
* **Pain relief:** Mild to moderate pain (e.g., headache, muscle aches, dental pain).
* **Fever reduction:** Reduction of fever.
* **Inflammation:** Management of inflammatory conditions.
* **Cardiovascular protection:** Prevention of myocardial infarction and stroke in patients with a history of these events or with specific risk factors. This is often referred to as low-dose aspirin therapy.
## Adult Dosing
* **Analgesic/Antipyretic:** 325 mg to 650 mg orally every 4 to 6 hours as needed. Maximum daily dose typically not to exceed 4000 mg.
* **Anti-inflammatory:** 2400 mg to 3600 mg orally per day in divided doses (e.g., 650 mg every 4 hours, or 975 mg every 6 hours). Doses should be individualized based on patient response and tolerance.
* **Cardiovascular Protection (Prophylaxis):**
* **Secondary Prevention:** 75 mg to 325 mg orally once daily.
* **Primary Prevention:** Dosing varies based on risk assessment and local guidelines; commonly 75 mg to 100 mg orally once daily.
Specific dosing for cardiovascular indications should adhere to established guidelines and physician judgment.
## Pediatric Dosing
* **Analgesic/Antipyretic:** Dosing is typically based on weight.
* **10 mg/kg/dose to 15 mg/kg/dose orally every 4 to 6 hours.**
* **Maximum daily dose:** 75 mg/kg/day, not to exceed 4000 mg/day.
* **Inflammatory Conditions (e.g., Juvenile Idiopathic Arthritis):** Higher doses are used, typically initiated at 30 mg/kg/day to 60 mg/kg/day in divided doses and titrated up to 80 mg/kg/day to 100 mg/kg/day, not to exceed 4000 mg/day. Dosing requires careful monitoring.
**Important Note:** Aspirin should be avoided in children and teenagers with viral infections (e.g., influenza, chickenpox) due to the risk of Reye's syndrome.
## Dose Adjustments
No specific dose adjustments are typically required for renal or hepatic impairment, but caution is advised, especially in severe impairment, due to potential for accumulation and increased risk of adverse effects.
## Contraindications
* Hypersensitivity to aspirin, salicylates, or NSAIDs.
* Asthma, urticaria, or other allergic-type reactions after taking aspirin or other NSAIDs.
* Active peptic ulceration or gastrointestinal bleeding.
* Bleeding disorders.
* Severe hepatic or renal impairment.
* Children and teenagers with viral infections.
## Adverse Effects
* **Gastrointestinal:** Dyspepsia, heartburn, nausea, vomiting, abdominal pain, gastritis, peptic ulceration, GI bleeding, perforation.
* **Hematologic:** Increased bleeding time, bruising, epistaxis, prolonged bleeding from wounds.
* **Auditory:** Tinnitus, hearing loss (especially at higher doses).
* **Renal:** Renal insufficiency, interstitial nephritis.
* **Hepatic:** Hepatic dysfunction.
* **Hypersensitivity:** Bronchospasm, urticaria, angioedema, anaphylaxis.
* **Reye's Syndrome:** In children and teenagers with viral infections.
## Key Drug Interactions
* **Anticoagulants (e.g., warfarin, heparin, direct oral anticoagulants):** Increased risk of bleeding.
* **Other NSAIDs and Salicylates:** Increased risk of GI toxicity and bleeding.
* **Corticosteroids:** Increased risk of GI ulceration and bleeding.
* **Antihypertensives (e.g., ACE inhibitors, ARBs, diuretics):** NSAIDs can reduce the efficacy of these drugs and increase the risk of renal impairment.
* **Methotrexate:** Increased methotrexate toxicity due to reduced renal clearance.
* **Uricosuric agents (e.g., probenecid):** Decreased uricosuric effect.
* **Selective Serotonin Reuptake Inhibitors (SSRIs):** Increased risk of bleeding.
* **Alcohol:** Increased risk of GI bleeding.
## Monitoring
* **Signs and symptoms of GI bleeding:** Melena, hematemesis, abdominal pain.
* **Bleeding:** Monitor for increased bruising, prolonged bleeding from cuts, epistaxis.
* **Renal function:** Especially in patients with pre-existing renal disease or those taking concomitant nephrotoxic agents.
* **Hepatic function:** Particularly with long-term, high-dose therapy.
* **Tinnitus and hearing changes:** May indicate salicylate toxicity.
## Clinical Pearls
* The enteric coating is intended to reduce gastric irritation but does not eliminate the risk of GI bleeding or ulceration. Take with food or milk if GI upset occurs, though this may delay absorption.
* Do not crush or chew enteric-coated tablets, as this will destroy the coating and may lead to premature release and gastric irritation.
* Aspirin's antiplatelet effect is irreversible and lasts for the life of the platelet (about 7-10 days).
* In patients undergoing surgery, aspirin should generally be discontinued 7-10 days prior to elective procedures to minimize bleeding risk.
* Salicylate toxicity can manifest as tinnitus, hearing loss, dizziness, confusion, and hyperventilation.
